The technical field

This invention relates, generally, to the field of small portable electronic devices and, in particular, to a dual-mode portable communication devices or mobile stations with the input using the keyboard. More specifically, this invention relates to keyboards for text input, intended for use in such devices.

The level of technology

Existing or keyboard small keyboard small portable devices often use a standard 12-key telephone small keyboard (herein collectively called "small keyboard"). Such small keyboards typically contain four rows of keys with three keys in each row. The first three series usually consist of numbers 1-9, arranged from left to right, from top to bottom in ascending order. The fourth row consists of a key "*", "0" and "#". Alphabetical values assigned to the number keys 2-9 in a standardized alphabetical order. Typing using such a small keyboard requires input unaccustomed to the user. Other types of keyboards correspond to the models of Dvorak keyboards or, what is more location is defamiliarised, QWERTY and are used in portable mobile devices such as RIM 950 Wireless Handheld™. In this type of keyboard, optimized for portable devices that use many small individual keys that are optimized for performance using the thumbs of the user. However, this keyboard contains a significantly greater number of keys than the small keyboard, and a larger number of individual keys requires more space on a printed circuit Board (PCB), than this requires a small keyboard. Usually for each key on the printed circuit Board requires its own bearing surface and the switch. Because of the relatively small size of such portable devices PCB space is limited, and the keyboard type QWERTY or Dvorak takes on the PCB valuable floor space.

In addition, to create such a keyboard in a large volume required technical processing to be placed in the housing of the portable device a large number of individual keys. This technical processing increases the cost of production. In addition, on your keyboard type QWERTY difficult to enter numbers, such as entering a phone number. Traditionally, phone numbers injected, using a small keyboard, and the application for the implementation of such a keyboard type QWERTY, which cimiracemoside in the row above the letters, is inconvenient for the user.

So desirable is to reduce the number of keys required for a layout keyboard type QWERTY or Dvorak used in portable devices or in conjunction with them. Also desirable is the Union of the functionality of the keyboard type QWERTY and a small keyboard for use in the dual mode communications device.

Brief description of the invention

The purpose of this invention is to eliminate or reduce at least one of the drawbacks of the existing keyboards or small keyboards that are used in small portable electronic devices or in conjunction with them.

In the first aspect of the invention is a keyboard for a mobile device. The keyboard contains an alphabetic key, set of alphanumeric keys, the command key and the Converter keyboard. Alphabetical key corresponds to at least one alphabetic value and is used for the excitation signal corresponding to at least one alphabetic key value. Each of the set of alphanumeric keys correspond to the digital value and at least one alphabetic value and is used for the excitation signal, which corresponds to digital and at least one alphabetic value CL is Vichy. Many alphanumeric keys are arranged in such a way as to create a digital layout small phone keyboard, and existing in the present preferred embodiment, a full small keyboard. The specified set of alphanumeric keys located together with an alphabetical key to create a standard layout keyboard. The command key is used for the excitation signal corresponding to the value of the command key. Converter keyboard is designed to receive signals generated by an alphabetic key, set of alphanumeric keys and command keys, and for converting the received signals into a sequence of alphanumeric, alphanumeric and command values. In the existing presently preferred embodiment, a standard layout keyboard is a traditional layout of the QWERTY keyboard and the keypad is located in its center. In an alternative embodiment, the alphabetic key, set of alphanumeric keys and the command key is created by using touch electronic display, which preferably is a sensitive to touch (touch) LCD display. In another the embodiment, the alphanumeric keys contain only alphabetical values. In another embodiment, the invention alphabetic key and each of the set of alphanumeric keys create one signal input for Converter key is pressed, which uses the predictive input text to convert the received signals into a sequence of alphanumeric and command values. In another embodiment, a command key corresponds to one of a group of keys consisting of ALT, SPACEBAR keys, RETURN key, BACKSPACE and SHIFT keys.

According to the second aspect of the invention is a mobile device, such as a two-way pager, a device for data transmission, a personal information device (personal digital assistant) and cell phone. The mobile device includes a keyboard, a microprocessor, and software executed by the microprocessor. The keyboard contains an alphabetical key that corresponds to at least one alphabetic value for the excitation signal corresponding to at least one alphabetic key value, lots of alphanumeric keys, each of the multiple keys correspond to the digital value and at least one alphabetic value, each key is designed to vozbuzhdeno the signal, a digital and at least one alphabetic values, many of the alphanumeric keys is thus to create a digital layout small phone keyboard, and is located together with the alphabetical key to create a standard layout keyboard command key for the excitation signal corresponding to the value of the command key, and the Converter keypad for receiving signals generated by an alphabetic key, set of alphanumeric keys and the command key, to convert the received signals into a sequence of alphanumeric, alphanumeric and command values. The microprocessor in online mode connected with a keyboard and receives from the keyboard a sequence of alphabetic, alphanumeric and command values, which are used to control the operation of the device. Application software is designed to produce a variety of performance and to create these characteristics in the exercise of certain inputs from the keyboard.

Detailed description

In General, the invention is a reduced-size keyboard for mobile devices, which enables the user to use a standard keyboard with fewer keys at the same time preserving the layout of the digits standard small keypad, such as keypad DTMF (Dual-Tone Multi-Frequency (DTMF set (numbers)) (DTMN). Although preferred in the present embodiment of the invention provides a complete duplication of the standard small keyboard, various embodiments of the present invention offer only the layout of the digits standard small keyboard, and the keys "*" and "#" are located in other positions on the keyboard. Preferred in the present embodiments of the invention offer a standard small keyboard DTMN, but also provides other standard small keyboard, such as those which are equipped with computer keyboards.

By reducing the number of keys that are used to create a standard keyboard, this invention enables the manufacturer to reduce the number of convex switches on the circuit Board and the amount of technical tools needed to create holes on the front Board of the mobile device. In addition, the abbreviated number is the primary objective of the keys also allows the user to operate the keys of a larger size, placed on the same surface of the device, which would otherwise be required to accommodate keys for all twenty-six alphabetic values, ten digital values and at least two non-alphanumeric values. As disclosed herein, the keys associated with alphabetic characters, less than 26, so that the number of alphabetic keys is reduced in comparison with the standard keyboard layout. The number of alphabetic keys more than nine. Thus, the keyboard keys associated with alphabetic characters, less than 26 and more than nine, so the number of alphabetic keys is reduced in comparison with the standard keyboard layout. The use of keys larger size reduces the complexity associated with the actuation of a single small key, which is surrounded by other keys.

According to the drawings Figure 1 is a block diagram of the mobile communication devices 10, which can be used in this invention. The mobile device 10 connection preferably is a dual-mode communication device that has the capacity, at least to transmit the voice signals and information. The device preferably has communication capabilities with other computer systems via the Internet. Depending on the functions the optional features of the preferred device can be used as a device for data transmission bilateral pager, cell phone with the capability to transmit data wireless device to access the Internet or a wireless device for data transfer (which may or may not have phone capabilities).

In those cases, when the device 10 has the ability to perform two-way communication, the device may contain a subsystem 11 communication that includes a receiver 12, a transmitter 14 and associated components, such as presented in the singular or more, preferably embedded or internal antenna elements 16 and 18, local oscillators 13 and CPU processing module, such as the processor 20 digital signal processing (DSP). As is obvious to experts in the field of communications, particular design of the subsystem 11 will be dependent upon the communication network in which the device is intended to work. For example, the device 10, which will be used for the North American market may include a subsystem 11 communication, designed for operation within a mobile communication system Mobitex™mobile communication system, the DataTAC™ or data network based on CDMA 1X, while the device 10 intended for use in Europe may contain a subsystem 11 communication General Packet Radio Service (GPRS) service (General packet radio use).

When the I, requirements for accessing a communication network, will also largely depend on the type of network 19. For example, in networks Mobitex and DataTAC mobile devices such as device 10, register on the network using a unique personal identification number or PIN associated with each device. However, in the GPRS access network associated with a subscriber or user of the device 10. Therefore, for a device intended for operation in GPRS network, is required to establish the identity of the subscriber (not shown), typically called a SIM card. Without a SIM card, the device operating in the GPRS network, will not be fully functional. Communication functions of a local character or brick and mortar (if they exist) can be carried out, but the device 10 will be unable to perform any functions that use the communication within the network 19. When required network registration or activation is completed, the device 10 may send and receive communication signals within the network 19. The signals received by the antenna 16 through a network of 19 links, are input to the receiver 12 information, and the receiver 12 may perform such common features of the receiver as the amplification of signals, transformation with decreasing frequency, filtering, switching channels, and so forth, and in the example system shown in figure 1, the analog-to-digital is converting video. Analog-to-digital conversion of the received signal allows more complex communication functions such as demodulation and decoding, which will be executed in the CPU 20 of the digital signal processing. Similarly, signals that are transmitted, treated, including, for example, modulation and coding, using the processor 20 digital signal processing and applied to the transmitter 14 for digital to analog conversion, conversion with increasing frequency, filtering, amplification and transmission over the network 19 communication via an antenna 18.

The CPU 20 of the digital signal processing not only processes communication signals, but also provides control of the operation of the receiver and transmitter. For example, amplification, created for communication signals in the receiver 12 and the transmitter 14 can be adaptively controlled by algorithms of the automatic gain control used in the processor 20 of digital signal processing.

The device 10 preferably includes a microprocessor 38, which controls all operations of the device. Communication functions, preferably including at least data and voice signals are performed using subsystem 11 connection. The microprocessor 38 also interacts with additional device subsystems such as the display 22, flash memory 24,random access memory (RAM) (or RAM) 26, an additional subsystem 28 input/output (I/O), serial port 30, keyboard 32, speaker 34, microphone 36, the subsystem 40 near relations, and any other subsystem of the device, generally indicated as 42.

Some of these subsystems is shown in figure 1, functions, communication-related, whereas other subsystems may provide "resident" or function that is directly associated with the device. Notably, some subsystems, such as the keyboard 32 and the display 22 can be used for functions related to communication, such as entering a text message for transmission over the communications network, and for resident functions such as a calculator or task list.

Software operating system used by the microprocessor 38, preferably stored in a persistent store such as flash memory 24, or in the permanent memory (ROM) or similar element for storage (not shown). For specialists in this field it is clear that the operating system, special application devices or parts thereof, may be temporarily loaded into temporary memory such as RAM 26. It is assumed that the received communication signals can also be stored in RAM 26.

The microprocessor 38, in addition to its operating system functions, predpochtitel is but provides the ability to perform on the device application programs. Predefined set of application programs which control basic device operations, including, for example, an application program for transmitting data and voice signals can usually be installed on the device 10 during manufacture. The preferred application program, which can be loaded into the device, can be an application program, the personal information management (PIM) (PIM)with the ability to organize and manage data pertaining to the user device, such as, but not limited to, e-mail, calendar events, voice mails, arrangement of appointments and task list. Naturally, the device must be accessible to one or more storage memory to facilitate data storage FOXES. The application program LIS preferably has the ability to send and receive data using a wireless network. In a preferred embodiment of the invention LIS data is fully integrated, synchronized and updated via the wireless network, with the relevant data user of the device, stored or associated with the system host computer, thus creating a mirror of the host computer on the mobile device in relation to at least the data. This may be OS is especially advantageous in the case, when the system host computer is on a mobile device of a computer system office user. Additional applications can also be downloaded to the device 10 via the network 19, an additional subsystem 28 for I/o, serial port 30, the subsystem 40 near field communication, or any other suitable subsystem 42, and they can be installed by the user in the RAM 26 or preferably in long-term memory (not shown) for execution by the microprocessor 38. This flexibility in the installation of application programs increases the functionality of the device and can provide advanced features that are directly associated with the device, the advanced features associated with the transmission of information, or both. For example, applications for secure communication can be made possible when using the device 10 functions of e-Commerce and other similar financial transactions.

In the data transmission mode of the received signal, such as a text message or downloading a web page is processed by a subsystem 11 communication and input to the microprocessor 38, which preferably additionally processes the received signal for output to the display 22 or, alternatively, an additional device 28 for input/output. The user of the device 10 mo the et also create data such as, for example, email messages, using the keyboard 32, which is preferably a complete alphanumeric keyboard or a small telephone type keypad, in conjunction with the display 22 and possibly an additional device 28 for input/output. The thus created data can be transferred over the communication network using the subsystem 11 connection.

For the purpose of transmitting voice signals General operation of the device 10 is basically similar, except that received signals are output to the speaker 34, and signals for transmission are generated by using a microphone 36. The device 10 can also be applied alternative voice or audio subsystem for input/output, such as a subsystem, recording a voice message. Although the output of the voice or audio signal is preferably carried out mainly through the speaker 34 can also use the display 22 to provide indication of the identity of the calling party, duration of a voice call, for example, or other data associated with the voice call.

Serial port 30, as shown in figure 1, is usually used in the communication device of the type of personal information devices (PDA), for which it may be desirable to synchronize with the desktop computer user (not shown), however, he Pawleys mandatory element of the device. A port 30 allows the user to set preferences through an external device or computer application program and may expand capabilities by providing information or software downloads to the device 10 other than those obtained using the wireless communication network. You can use, for example, an alternate load path in order to download to the device key encryption using a direct and thus reliable and credible connection to thereby provide secure device communication.

Subsystem 40 near relations is an additional optional element that can be used for communication between the device 24 and different systems or devices, which need not necessarily be a similar device. For example, the subsystem 40 may include a device operating on the principle of infrared radiation, and interactive diagrams and elements or Bluetooth communication module™ to create a connection with similarly performed by systems and devices.

Thus it is obvious that the portable device of this type perform a large number of complex functions and creating a keyboard that is compact enough to match the form factor per the man-portable devices but which would be required by the user the required level of functionality, is a difficult task.

Figure 2 presents a view of the device from above, showing the device in two parts: the front part of the frame 50 and the rear housing 52. This drawing also shows the location of the non-mandatory device 54, operating on the principle of infrared radiation. On the right side of the device 10 there are many additional input devices, including the coordinate pointing device 56.

Figure 3 presents a view of the device from the front. The front housing 50 contains a few holes for connection with multiple devices for input and output. Speaker 62, a display 22, a keyboard 32 and a microphone (not shown) preferably mounted inside the front surface 50 of the device. Preferably, the speaker is placed above the display 22 near the top of the front housing 50 about midway, when viewed horizontally, the front surface 50. Speaker 62 is situated above the display 22. Below the speaker 62 in the Central part of the front surface 50 sets the display 22. Although figure 3 shows the display 22 of rectangular shape, you can also use the display of another geometric shape. Arrow key 60 is preferably placed in close proximity to the display.

It is Aviator 32 and the microphone is preferably installed in the front case 50 below the display 22, although alternative microphone may be located between the display 22 and keyboard 32. The keyboard 32 is preferably placed in the Central part of the front surface 50, similarly include a display 22.

The keyboard 32 contains a lot of alphabetic and alphanumeric keys 32A, forming in one embodiment of the invention, the layout type QWERTY, as will be described in more detail below. In addition to the specified alphabetic and alphanumeric keys on the keyboard includes function keys and are not mandatory the spacebar 32V. Functions associated with these keys are defined by the arrangement of input devices. Alternative layout according to specific variants of execution of the invention shown in the drawings.

Figure 4 presents a view of the device on the right side according to a variant implementation of the present invention, the device contains a variety of input devices. These input devices may include a coordinate pointing device 56, the cursor keys 58, 60 and the key 64 of the transition. Other input devices are obvious to experts in the field. Although figure 4 shows the arrangement of these input devices, in which the arm 56 preferably is located between the two arrow buttons 58, 60, and the 64 transition is located below manip is the system 56, you can also use the alternative layout.

Figure 5 presents a view of the device with the left hand. On this side of the device illustrated in this case, the embodiment of the invention does not show any input devices, although alternate embodiments of the invention may contain on this side of the input device. In one envisaged embodiment of the invention, input device, shown in figure 4, is moved to the left side of the device to create a device with left-hand orientation. As should be clear to experts in this field, other alternative embodiments of the invention, in which the input device is distributed between two parties, or there is a back input device.

The location of the keyboard, as shown in Figures 6-12, is designed to minimize the number of keys required to create keyboard. The keyboard consists of alphabetical keys, which are keys that have only literal values, and alpha-numeric keys that correspond to keys having at least one literal value and the digital value. Keys have to literal values alphabetic and alphanumeric keys located in accordance with the standard is based layout of the keys. In addition, a key feature so that digital values alphanumeric keys located in accordance with the layout standard small phone keyboard. In addition to alphabetic and alphanumeric keys include at least one command key, which allows the user to switch between keyboard input so that the user could easily enter only alphanumeric values or only numeric values. In certain embodiments of carrying out the invention there are other command keys, such as "space"key, and a value of "space" can be assigned to the same key, which is assigned a numerical value, for example zero. Below, embodiments of the invention illustrate the layout of the QWERTY keys, although there are other standard configuration, such as the Dvorak keyboard. A reference to a standard keyboard or a standard layout keyboard should be understood as a reference to the configuration QWERTY, Dvorak and other known configuration.

Due to the fact that many keys correspond to many alpha (alphanumeric) or numeric values, the number of keys required to create a standard layout keyboard, reduced, making possible savings due to the fact that the circuit Board is required will attach the smaller number of keys. In addition, reducing the number of convex switches is necessary to ensure that the keys could operate in cooperation with the PCB. Reducing the number of keys used to create keyboard, makes possible a corresponding decrease in the technical means necessary for the manufacture of the front housing 50, which, consequently, reduces manufacturing costs and simplifies the design. This is advantageous for manufacturers of mobile devices such as portable devices become significantly smaller.

Figure 6 shows one possible layout for alphanumeric inputs on the keys 32A keyboard. Although an embodiment of the invention, shown in Fig.6, contains the keys that are assigned up to four different values (inputs), each key can be assigned more or fewer values. The invention is in no way limited to the specific distribution of marks shown in Fig.6.

The keyboard shown in Fig.6 illustrates the first embodiment of the layout of the keys on this invention. The Central section of keys, bounded by the dashed line 32C, forms a standard telephone small keyboard with numbers from 1 to 9, 0, symbols of the "stars" and "grid". The keys corresponding digital Zn is the values from 1 to 9, represent the alphanumeric keys, as in the possible values they have both numbers and letters. In this embodiment, the alphabetic keys, i.e. keys only alphabetical values are near the upper row of keys on each side of the alphanumeric small keyboard. This allows you to have two letters of each of the keys in the top row with the formation of the top row of a standard QWERTY keyboard. The second row of the small keyboard is increased on the left side due to the alphabetical keys, and on the right side due to the command key, which in this case is key, no alphabetical or numeric values. The command key on the right side of the middle line corresponds to the value of "ENTER" ("return") or RETURN ("return"). The bottom row of keys in a small keyboard ends on both sides of the command keys, one of them corresponds to the value of "ALT" (alternative), and the other corresponds to the value "BACKSPACE" ("return one position"). The symbols"*", "grid" and zero are in the bottom row, which is usual in the construction of a small keyboard. Key with a value of zero also assign the value "space", while the key with the symbol " * " with the key "ALT" can be used as a digital or basic use is based lock. The key with the symbol "grid" can be used with ALT to bring into effect the value of "SHIFT" ("change case") or "CAPS LOCK" (lock register capital letters"). Thus, in an embodiment of the invention, shown in Fig.6, assign two or three alpha values all alphabetic and alphanumeric keys.

The following embodiment of a layout of keys contains three rows, 31, 33 and 35, of the five keys in each and contains the key 32 In the space and two function keys 32F and 32G, below the three rows. In the first row 31 three middle keys allow for input of letters and numbers, and the keys along the edges allow for entering letters. Each key in the first row 31 is connected at least with the two literal values. In the second row 33 three middle keys allow for input of letters and numbers. The left button allows you to enter letters. The last key 32D is set to ENTER or RETURN. Because of this the values of the specified key, each of the two leftmost key in this row 33 is set to two literal values, while each of the keys 32I and 32J has three literal values. For example, in the layout key 32J allows you to enter the letter "G", "H" and "I", and the 32I allows you to enter the letter "J", "K" and "L".

In the third row 35 three middle keys which allow for the input of letters and numbers. The leftmost key N functions as the ALT key, allowing you to access special characters that can be assigned to each key 32A. When together with a key IN ALT press any of the alphanumeric keys, the user can access special characters or symbols (not shown).

The rightmost key E in the third row 35 preferably functions as a BACKSPACE key. When press E, removed any text input, which was carried out immediately before pressing E.

In the third row 35 three middle keys are alphanumeric and in this example, key 32M allows three letter input, namely "Z", "X" and "C".

Key 32V SPACE is located in the center, below the third row 35. On each side of the SPACE key function keys are 32G and 32F. In this example, the right soft key 32F (marked) is preferably used as CAPS for the implementation of the letter to upper case. When you press the function key 32F, any letter key you press after that will be to enter upper case letters.

Left soft key 32G (marked as "123") are used preferably as NUMERAL keys ("digital") to access the numeric entry marked within pun is Tierno line 32C. Digital values of the keys that are restricted by the dashed line 32C form a conventional small keyboard DTMN. What these keys form the usual small keyboard DTMN, makes it easier for the user to enter such number sequences, as phone number. For the user it would be much harder to enter a phone number, if keys to enter numbers were located, as in the QWERTY keyboard.

Whenever you press the function key 32G "123", after you press one of these keys, enter the numbers above the alphabetic characters on the keys within the dotted line 32C.

7 shows a second embodiment of the present invention. As can be seen in Fig.7, the location of the small keyboard creates a standard digital small keyboard for the phone. Alphabetical values assigned to each of the alphanumeric keys, positioned so that each key assign only two alphabetic values, while in the embodiment of the invention, shown in Fig.6, you can assign a specific alphanumeric keys three alphabetic values. In an embodiment of the invention, shown in Fig.7, the command key corresponding to "ENTER"is moved in the second row from the bottom, and the value of the "SHIFT" key with the designation of "grid" is replaced by fu is the Ktsia "BACKSPACE". The value of "ALT" in this embodiment of the invention corresponds to the asterisk key. Thus, an embodiment of the invention, shown in Fig.7, offers layout of the keyboard, in which each alphabetic or alphanumeric key assigned no more than two alphabetic values.

In an embodiment of the invention, shown in Fig.7, each key 32A assign at most two literal values. Key 32K RETURN can be located where the rightmost key of the third row 35. Key 32L BACKSPACE is an extreme right soft key next to 32V SPACE, which is located below the third row 35. Key 32M ALT is an extreme left soft key next to 32V SPACE. In contrast to the layout shown in Fig.6, the layout of the keyboard shown in Fig.7, requires the use of additional keys out of the keyboard to make entering numbers located within the dotted lines 32C, and enter uppercase.

On Fig, 9, 10, 11 and 12 show other embodiments of the keyboard/small keyboard according to this invention. As shown in these drawings, the alphanumeric keys have one digital and at least one literal value. In addition, there are alphabetic keys, which is passed only have literal values. These keys can have one or many values. Values denoting commands can be assigned to either the command keys, or they can be combined with either alphabetical or numeric value. In each of the embodiments each key can be attributed to the category alphabetic, alphanumeric, or command keys. In an embodiment of the invention shown in Figure 10, the digital values of the small keyboard is located in the left part of the configuration key, while the key with the symbol "grid" and "stars" are located in the right part. In addition, there is a guide keypad with additional command functions. To a person skilled in the art will understand that the guide a small keyboard can be replaced or set of rails keys, or device type joystick.

On Fig shows an embodiment of the present invention, in which the standard TMN layout 32C small keyboard reproduce in the Central part of the keyboard 32. Rows 31, 33 and 35 create three row of a standard QWERTY keyboard. Press "*" with the key "ALT", on the left side of number 35, is used to switch between letter and number modes. When the letter (alphabetical) mode key "#" is set or "SHIFT"or "CAPS LOCK", so that through it you can enter upper the e letter. When the alphabetic mode, press "0" to serve as a "SPACE BAR". Value "BACKSPACE" and "ENTER" is assigned to the rightmost keys in rows 33 and 35, respectively.

Figure 9 shows an embodiment of the present invention, in which the standard TMN layout 32C small keyboard reproduce in the Central part of the keyboard 32. Rows 31, 33 and 35 create three row of a standard QWERTY keyboard. Press "*" with the key "ALT"below the leftmost key in row 35, is used to toggle between alphabetic and numeric modes. When the alphabetic mode key "#" is set or "SHIFT"or "CAPS LOCK", so that through it you can enter uppercase letters. This arrangement represents the configuration of the keyboard in which one key assign no more than two alphabetic values. When the alphabetic mode, press "0" to serve as a "SPACE BAR". The value of the "BACKSPACE" assign extreme right in row 35, and ENTER keys located below the BACKSPACE key.

The layout of the keyboards shown in Figures 8 and 9 differ from the layout of the keyboards shown in Figures 6 and 7 in relation to the location of the key "BACKSPACE" and "ENTER".

Figure 10 shows an embodiment of the present invention, in which the standard TMN keyboard 32C is located on the half of the standard small keyboard. Nine digital value is located in the first three columns of the rows 31, 33 and 35. Key "0" is lower than the number 35 in a relatively Central position in relation to the small keyboard DTMN. The keys "*" and "#" are located on the second half of the keyboard so that fully represented only a small layout keyboard DTMN digital values. This arrangement creates an extended configuration and keyboard contains a separate press "SPACEBAR", at the same time reducing the number of keys required to create the full standard keyboard.

Figure 11 shows an embodiment of the present invention, in which the standard TMN layout 32C small keyboard reproduce in a relatively Central part of the keyboard 32. Rows 31, 33 and 35 create three row of a standard QWERTY keyboard. Press "*" with the key "ALT", which is the leftmost key in row 35, is used to toggle between alphabetic and numeric modes. When the alphabetic mode key "#" is either the value of "SHIFT", or is "CAPS LOCK", so that through it you can enter uppercase letters. This arrangement creates a configuration keyboard, in which a single key assign no more than two alphabetic values. In the alphabetic mode, press "0" to serve as a "SPACE BAR". Value "BACKSPACE" and "ENTER" is assigned to the rightmost keys in rows 33 and 35, respectively.

On Fig shows a variant is carried out this invention, in which the standard layout keyboard 32 create by using four columns. Layout 32C small keyboard DTMN create three columns, located on the keyboard to the left, while to a person skilled in the art will understand that a small keyboard DTMN can also be represented in the form of three columns located on the right. In rows 31, 33 and 35 are three row of a standard keyboard. Press "*" with the key "ALT", which is located below the rightmost key in row 35, is used to toggle between alphabetic and numeric modes. In alphabetical mode key "#" is either the value of "SHIFT", or is "CAPS LOCK", so that through it you can enter uppercase letters. In the alphabetic mode, press "0" to serve as a "SPACE BAR". Value "BACKSPACE" and "ENTER" is assigned to the rightmost keys in rows 33 and 35, respectively.

For the person skilled in the art it is clear that once installed on a printed circuit Board, each key activates convex switch or other similar device known to specialists in this field. When pressing the key initiates a signal that is happening by clicking on the convex switch and due to the fact that the electric current reaches Converter keyboard, which receives the signal from the convex switch. On the basis of the received signal of the inverter keypad may determine, what key was pressed.

When using this invention, the user gets the opportunity to work with a standard keyboard layout, such as configuration QWERTY or Dvorak. This allows the user to avoid using way to find the letter and enter it" ("hunt-and-peck"), which applies when using a standard telephone small keyboard, in which alphabetic values assigned to each key are in normal alphabetical order. When pressed, she initiates a signal corresponding assigned alphabetical and numerical values, depending on what you want. For keys with multiple alphabetic values used Converter key is pressed in the Converter keypad to determine the implied alphabetical value corresponding to each key. The Converter keypad or use the input predictable text, or to use what is called in the art "method. (on the keys)". In the way "." button to click once to get the first alphabetic value assigned to the key press press a second time to show that the desired is the second alphanumeric value assigned to the key, and so on. Therefore, the user may need to press the key several times to get the desired value. When using input predictable text Converter pressing receives a sequence of keystrokes, coordinates of the received sequence with the database sequences that match the words. Conventional algorithms input predictable text available under trademarks Tegic T9™ and Motorola's iTAP™. Specialist in the art will easily understand the advantages of using input predictable text with this arrangement, a small keyboard.

It is assumed that the use predictable text can be activated once committed a certain number of keystrokes so that you can identify the root word and the whole word to predict. Initial signs in the root of a monomial with a minimum length can be selected manually, for example by pressing a key several times by holding the key down, or by actuation of the next key or enter the hold at the same time, key in the pressed state.

It is also assumed that a small keyboard you can create on the electronic touch screen such as a liquid crystal display (LCD) (LCD), and that the switch between alphabetical and numerical values by entering the command will be removed from displaylink alphabetical values, either the numeric values assigned to the keys so that the user can recognize which mode is used. The following estimated embodiment, the alphanumeric keys assign only alphabetical values, so that creates embodiment of a keyboard with fewer keys, preserving at the same time, standard layout keyboard. In this configuration, the number of the numeric keys is usually combined with the layout of the keyboard to create a small keypad for entering phone numbers.

As shown by the many embodiments of the invention, the scope of the present invention is not limited to a specific location alphabetic and alphanumeric keys, as simple swap these keys within the scope of the present invention, can be performed by a person skilled in the art after reading the present description. Thus, this invention provides a configuration of a small keyboard/keypad containing a reduced number of keys, which reduces the amount of technical equipment for manufacturing and processing devices in order to reduce the occupied area on the circuit Board and allows the user to quickly enter data.
