DETAILED DESCRIPTION of embodiments of the INVENTION

In versions of the invention, the user can implement the security in the electronic device 10 by executing an ordered sequence of rotations of the rotator 32. The device 10 provides, separately from the rotator 32, feedback to the user when turning the rotary device 32 at the time ordered sequence for oratov. Checks whether an ordered sequence of rotations performed by the user, the preset sequence of turns. This check may occur in the device 10.

Figure 1 illustrates the portable electronic device 10 containing the memory 12, the means 20 user input device 14 audio output, the image output device in the form of a display 16 and a processor 18. The processor 18 is connected to receive input control signals from the means 20 input and to apply the appropriate control signals to the device 14 audio output and a display 16. The processor 18 is also connected to memory 12 is read from the memory 12 and the entries in the memory 12.

The device 14 audio output provides an electrically amplified audio output signal to the user.

The memory 12 stores the secret code in the form of a predetermined sequence of characters. Predefined sequence of characters may be specified by the user.

Portable electronic device in this example operates as a mobile cell phone. In other examples, the portable electronic device may not have this functionality. The electronic device 10 further comprises a cellular transceiver 13, connected to the processor 18, which makes possible the implementation of communication in a cellular network St is zi (not shown).

Means 20 include input rotary tool 30 input and additional function keys 22. The rotary means 30 takes the input from a first control input signal 31 in the processor 18, and the function keys 22 serves the second control input signals 23 to the processor 18.

The rotary tool 30 entry includes rotated by the user rotating the device. The rotation of the rotator changes the continuous analogue electrical characteristic of the rotary input means. Periodically take samples electrical characteristics and quanthouse obtaining quantized values. The quantized value is some value from a discrete set of quantized values, each of which represents a different angular position of the rotary device. The quantized value is periodically sent to the processor 18 as a time varying first digital signal 31 of the control.

An example of executing a turning means 30 input schematically shown in cross section on figa and plan on figv.

The rotary tool 30 input in this example replaces the keyboard. The rotary tool 30 input can be used for data entry, for example, to dial a phone number or enter alphanumeric text. Each of the many different angular positions of the rotary device which may correspond to a particular input symbol.

The rotary tool 30 entry includes discoid rotary device 32 installed with the possibility of rotation around the axis 34, in response to tactile stimuli to the user. Discoid rotary device 32 has a circular flat top tactile surface 36 that is designed to impact the user's fingers.

When using the device, the user touches the upper tactile surface 36 of the finger. When the movement of the finger in contact with the upper tactile surface 36, the friction between the user's finger and the upper tactile surface 36 causes discoid rotary device to rotate.

Circular upper tactile surface 36 has a downward curved edge 38 that is essentially inaccessible to the user. The axis 34 of rotation in this example is essentially perpendicular to the upper tactile surface 36. Electronic device 10 has a front surface 11 and the axis 34 of rotation in this example is essentially perpendicular to the front surface 11 of the electronic device.

The processor 18 provides the means of verification of the current user-entered sequence of rotations of the rotator (test sequence) by comparing with a predetermined sequence of rotations of the rotator. The EU and the verification is successful, the procedure security is successfully completed, and access. If the verification fails, the procedure of the security fails and access is denied. Access can refer both to the use of an electronic device 10 in General, and some of the functionality provided by this device.

The processor 18 receives the first control signal 31 from the rotary means 30 input. This signal indicates the current angular position of the rotator 32. The processor 18 also receives the second control signal 23 from the first function keys selectable by the user to indicate completion of the rotation, and the second function keys selectable by the user to indicate completion of a sequence of turns.

The user rotates the rotator and then presses the first soft key to indicate completion of the rotation. This is repeated for each rotation of the sequence of rotations of the rotator. Then the user presses the second function key to indicate completion of a sequence of turns.

After each complete rotation processor 18 converts the current quantized value, which is the first control signal 23, a single data value from a set C is achene data "character". In this example, the transformation is performed in the ASCII character set. The processor 18 stores the symbol in the memory 12 as a serial addition test sequence of characters.

After completion of the sequence of turns, marked by the signal input of the second function key, the CPU 18 checks the user-entered test sequence of characters matches a stored predetermined sequence of characters. If the verification is successful, the procedure security succeeds, and access is allowed. If verification is unsuccessful, the procedure of the security fails and access is denied. Access can refer both to the use of the electronic device 10, and some of the functionality provided by this device.

The processor 18 in addition to performing the function of providing secure access, described above, also controls the feedback provided to the user during security procedures. Provide feedback is separate from any noise or tactile feedback provided to the user turning device 32 as it rotates.

The processor 18 controls the display to provide visual feedback, as the show is about to figa, 3B, 3C and 3D.

The display is initially controlled by the processor 18 to display the image locked box 40 that is illustrated in figa. The image of the safe includes a housing 42 of the safe, the door 44 of the safe and dialer 46 safe on the door 44 of the safe. The current input symbol 50 is displayed by displaying the current angular position of the dialer safe. The sequence of characters 52 is displayed by the display previously entered turns dialer box 46 in the current sequence.

The image to be displayed during the rotation of the rotator 32 clockwise to its next discrete quantized value, illustrated in figv. When the processor 18 determines that the first input signal 31 is changed, since the rotary device is rotated until the next discrete quantized values, the processor 18 converts the new discrete quantized value in the symbol indicates this symbol on the display, and turn the dialer safe on the image of a safe and delivers the first control signal sound in the audio output device.

In more detail, when the controller 18 determines that the first input signal 31 is changed, the processor 18 converts the current quantized value represented by the first control signal 23, ASCII character, otobrazhayut value as the current input symbol. This example shows the current input symbol 50 is "4". The value displayed is the current input symbol discretely increases as the rotation of the rotator clockwise and discretely decreases as the rotation of the rotary device in a counterclockwise direction. The display under control of the processor 18 provides feedback on the absolute degree of rotation of the rotary device, represent the current input symbol 50.

In more detail, when the controller 18 determines that the first input signal 31 is changed, the processor 18 converts the change of the first input signal 31 to change the displayed image of the box so that the dialer box shown on the picture seems to be rotatable together with the rotating device and is similar to him. The angular position illustrated in the drawings with the use of arrows.

In more detail, when the controller 18 determines that the first input signal 31 is changed, the CPU 18 supplies the first control signal sound in the audio output device. This signal controls the audio output device to produce an audible "click"sound that mimics the sound that is created by the rotation of the dialer safe. Thus, the audio output device under control of the processor 18 provides feedback on the relative change in the structure of the angular position of the rotator. Each preset position when turning the device enables the change of the quantized signal, which in turn provides a 'click'.

When the processor 18 determines that the turn is finished, it controls the display so that the current input character is moved in the sequence of characters in place of the last character of the sequence 52 of symbols, see figs.

If the verification performed during the security procedures, the successful, the processor 18 controls the image presented on the display 16, so that it seemed as if the door opens, as shown in fig.3D, and simultaneously controls the audio output device to make a sound similar to the sound of the opening door.

In the above description, the end of the turn is marked by the user pressing the first soft key. In other embodiments, the completion of the rotation can be indicated by the user in other ways. For example, the user can change the direction of rotation of the rotary device on the opposite, the processor 18 may be configured to detect changes direction and takes quantized values that occurred before the change of direction as the input value corresponding to the end of the turn. Or, n the example, the user can pause in the movement of the rotary device, for example, more than 0.5 seconds, and the processor 18 may be configured to recognize such a long pause and take quantized values in the moment of pause, as the input value corresponding to the end of turn.

Although embodiments of the present invention have been described above with respect to various examples, it should be understood that modifications of these examples can be made without deviating from the essence and in the framework of the claimed invention. For example, although described discoid rotary device can be used in other forms of rotary devices. For example, the rotator may have the form of a wheel or drum, where the user acts on the curved surface of the rotator. Or, for example, although in the described example, the verification procedure is done in hardware, it can alternatively take place anywhere. For example, the secret code in the form of a predetermined sequence of characters can be stored on the remote station, and the device may send a message indicating the test sequence of characters to the remote station, a remote station may provide a means of verification for the comparison of the received test sequence of characters stored ZAR is it a given sequence of characters.
