The technical field to which the invention relates.

This invention relates to a controlled using the touch screen navigation device that can display navigation data. The device may be used, in particular, as a navigation system installed in the vehicle.

The level of technology

Based on the global positioning system (GPS) devices are commonly known and widely used as car navigation systems. The prior art known software series Navigator applicant of this application TomTom B.V. It is a software that when used in a personal digital assistant (PDA) such as the Compaq iPaq), connected to an external GPS receiver that allows the user to enter into the PDA start and end address. Then the software can calculate the best path between two endpoints and display commands for navigation on this route. Through the use of positional information obtained from the GPS receiver, the software may with uniform intervals to determine the position of the PDA (usually mounted on the dashboard of your car) and can display the current position of the vehicle on the map and display (and pronounce) suitable navigation commands (the example turn left after 100 meters). Graphic symbols showing the subject performing the action (for example, the left arrow next left turn) can be displayed on the ruler, and superimposed on the corresponding intersections/turns, etc. of the streets shown on the map. Also known device that integrates a GPS receiver in a computing device programmed with a database of maps and executed with the ability to create navigation commands on the display. The concept of "navigation device" refers to a device that allows the user to specify a path to a specific destination. The device may have an internal system for receiving location data such as GPS receiver, or may be performed only with the possibility of connection with the receiver that can receive location data.

In PDA usually use the touch screen to let the user select or enter text/numbers using the virtual keyboard. Usually, touch input is performed with the use of a thin pen, because the size of the individual virtual keys or other selectable objects is relatively small. When navigating to a screen related to a single function or type of function, the implementer is on to another function or type of function, it is assumed that you select with the stylus virtual keys, control panels, independent switches, etc. as appropriate zones touch controls are relatively small.

However, in some applications, such as the use of the calculator, each digital key may be large enough for selection using your finger, not a stylus. However, when you want to display simultaneously a large number of keys (for example, for a standard keyboard or a virtual keyboard in a different format with all the letters of the alphabet), it is necessary to use a much smaller virtual keyboard; in this case, the private key must be selected using the pen. Therefore, the device according to the prior art can mix large numeric keys available on one screen, with much smaller keys on another screen, but the keys have the same importance. Not to say that the basic functions are designed uniformly and consistently for the efficient and reliable operation of the fingers because it is assumed that in most cases users are working with the pen.

The invention

According to the first aspect of the present invention created a navigation device programmed with a database of geographical CT and software which provides route planning between two user-defined points, where the device is additionally programmed to enable communication of any function relating to the basic set of functions, with non-overlapping area of the touch input, which is large enough for reliable actuation using a finger.

Therefore, this invention is based on the understanding that it is possible to identify a set of basic functions and then provide them a reliable choice/actuation by touching a finger to a touch area input large enough for reliable actuation. It is especially preferred for automotive navigation devices, in which the basic functions are those functions that are likely to actuation by the driver, while the device is mounted on the dashboard and the driver leans forward, doing the driving (for example, standing or moving, if traffic conditions allow it). Basic functions preferably include functions that cannot be selected or used with the same screen (i.e. they are not limited to only certain keys displayed simultaneously on the display). Therefore, the basic function is to usestat on several different screens.

This approach to user interaction with the system is simpler, more flexible and more intuitive than the approaches according to the prior art.

Detailed description of the invention

The principle of operation of the system

This invention implemented in software company TomTom B.V. called Navigator. This software via the touch screen (i.e. the UE is supplied with a pen) a pocket PC or personal digital assistant (PDA), such as the Compaq iPaq. This provides a GPS based navigation system, PDA when connected to a GPS receiver. Combination of PDA and GPS receiver system is designed for use in car navigation system. The invention can be implemented in any other layout of the navigation device, such as integrating a GPS receiver, a computer display, or in the navigation device is not for use in the car (for example, pedestrians, or vehicles other than the vehicle (e.g. aircraft). The navigation device may use any technology to determine the location and is not limited to GPS; it can be implemented using any other global satellite navigation systems (GNSS), such as the European Galileo system. It also is not limited based on satellites systems determine position/velocity, and can be carried out using a bound to the surface of the rays or any other system that allows the device to determine the geographic location.

Software Navigator when used in PDA leads to the creation of the navigation device displays the normal mode navigation is shown in figure 1 display. This display provides commands using the m combinations of text, characters, voice commands, and moving maps. Key elements of the user interface are: two-dimensional geographical map 1, which occupies most of the screen. The map shows the car user and the immediate environment, is rotated so that the direction in which the car is traveling, is always on the top. On the bottom quarter of the screen is line 2 States. The current location of the device that identifies the device itself using a normal GPS system, and its orientation (defined direction) indicated by an arrow 3. The route calculated by the device (using the algorithm of calculation of the route stored in the memory device in the data maps stored in the database of maps in a memory device) shown as the shaded path 4 overlaid with arrows indicating the direction of movement. The darkened path 4 all major actions (e.g., turns, intersections, turns, etc.) is schematically shown by arrows 5, is applied to the path 4. Line 2 States also includes at its left-hand side of the sign 6 indicating the next action (in this case, turn to the right). Line 2 States also shows the distance to the next action (i.e. to turn to the right be the tion is 220 m), extracted from the database of the entire route, calculated by the device (for example, a list of all streets and related actions that define the route chosen). Line 2 indicates the name of the 8 current street, estimated time 9 before arrival to the goal (in this case 2 minutes and 40 seconds), the actual arrival time 10 (11.36) and the distance 11 to the destination (1.4 km). GPS signal strength is indicated in the indicator 12 power signal for use in mobile phones.

If the user touches the center of the screen 13, the menu appears on the navigation screen; with the help of this menu you can initiate or manage other basic navigation functions of the application program Navigator. Providing a selection of basic navigation functions from the menu screen, which itself is very easy invoked (for example, one step from display maps to the menu screen), greatly simplifies the user's interaction with the system and makes it faster and easier.

The area of the touch zone, which must touch the user, much more than in most systems with touch screen using the stylus. It is made large enough so that it can be reliably choose a single finger without much precision, i.e. simulation of real conditions for the driver operating the vehicle; he had the t little time to contemplate complex images on the screen with small icons management, and even less time for precise clicking on one of these small icons management. Therefore, the use of very large touch screen associated with the specified programmable key (or a hidden soft keys, such as the center of the screen 13)is a deliberate feature of the design of this implementation of the invention. Unlike other based on the use of the pen applications, this characteristic structure is applied consistently in the Navigator to select the basic functions that you will probably need the driver while driving. Therefore, when the user gets a choice of icons on the screen (for example, icons or control keys or virtual keys to enter, for example, the address of the destination), the design of these icons or keys is kept simple, and the corresponding area of the touch screen to increase the size, which allows to accurately select icons or keys with your finger. In practice, the corresponding area of the touch screen is of the order of at least 0.7 cm2and is usually square area. In normal navigation mode, the device displays a geographical map. Disposable (or two in some embodiments, execution) touch maps (i.e. touch screen) near his summe is zi centre of the screen (or any other part of the screen in another embodiment, the), causes the navigation menu (see figure 3) with large icons corresponding to the various navigation functions such as the ability to calculate an alternative route, or re-calculation of the route to exclude the next stretch of road (useful when you encounter obstacles or large tube); or to re-calculate the route to the exceptions specifically mentioned streets.

The actual physical structure of the device may not be different from any normal computer, except integrated GPS receiver or feed GPS data from an external GPS receiver. Therefore, the memory contains algorithms for computing routes database of maps and software user interface; the microprocessor interprets and processes user input (for example, using a device with a touch screen for entering the start and end addresses and all other input control signals), and uses algorithms to calculate the route to calculate the optimal route. The "optimal" may refer to criteria such as minimum time or minimum distance, or any other relevant to the user factors.

Namely, the user enters their original location and the desired location on the values in the usual way in software Navigator running in the PDA, using the virtual keyboard. The user then selects the calculation method of the route: various modes, such as "fast" mode, which calculates the route very quickly, but the route may not be the shortest; "full" mode, which loops through all possible routes and chooses the shortest, but the calculations take more time, etc. other cases, when the user specifies the scenic route, which, for example, passes the most interesting points that have been identified as the most picturesque, or passing points of interest to children, or has the least number of intersections, etc.

The streets described in the database of maps, which is a piece of software Navigator (or to which there is another access), running in the PDA, in the form of lines, i.e. vectors (e.g., start point, end point, direction of the street with all the street consists of many hundreds of such sections, each of which is uniquely set start point, end point and direction). Thus, a geographical map is a set of such vectors streets with the addition of interesting points, names of streets and other geographic features, such as borders parks, river banks, etc. that are all set in the form of vecto the RC. All signs of maps (for example, vectors of streets, interesting points, and so on) specified in the coordinate system that matches or corresponds with the coordinate system of the GPS that allows you to display the location of the device determined using the GPS system, the appropriate street shown on the map.

To calculate the route uses complex algorithms that are part of software Navigator. The algorithms used for the calculation of a large number of different possible routes. Then software Navigator evaluates them according to user-defined criteria (or failure device), such as the full scan mode, the scenic route, museums and the lack of security cameras for observing the speed limit. Then the route that best meets the criteria is calculated by the processor in a PDA and is stored in the data RAM in the form of a sequence of vectors, street names, and subject to action at the end points of vectors (for example, match a given distance along each street route, such as a left turn on the street X 100 m).

The approach to the design of the user interface using finger

This invention relates to the actuation of the touch area with each set of base function with the transactions; this area is large enough to select a single finger without much precision. It shows the real conditions for the driver operating the vehicle; it does not have a lot of time for examining the detailed screen with small icons management, and even less time to correct clicking on this little icon control.

This characteristic of the user interface using finger consistently applied in software Navigator 2.0 to all your basic functions, but not the selective way, when the screen design allows you to display large icons control; therefore, in all cases, when the user has a choice on the screen of the certain items related to basic functions (for example, icons control or keyboard, or virtual keyboard for input, for example, the address of the destination), the design of these icons or keys remains simple, and the corresponding area of the touch screen expand to such a size that it is possible to accurately select each icon or press with your finger. In addition, when the display includes selectable graphical elements (for example, icons, names, independent switches and so on), each of these elements is associated with the display non-overlapping area with namogo input which is big enough for a reliable trigger with a finger.

Therefore, the device does not prompt the user at different points of time a mixture of selectable graphical elements related to the core functions, some of which are large enough to reliably trigger with your finger, and the other too small, so to bring them into action, you need the pen. The key point is that the design of the user interaction with the system is based on the analysis of possible underlying functions that may be subject to fulfillment by the driver while driving, and to enable actuation of the selected elements (for example, large graphic icons)associated with an unusually large area of activation of the touch screen. Approaches to the design of the user interface according to the prior art are not capable of logical to identify the basic functions and handle them this way.

In practice, the corresponding area of the touch screen is at least 0.7 cm2(much more than usual zone activate the touch screen), and is typically square area.

Examples of basic functions that logically using this approach are:

(i) moving between n the andá tertiary level in the menu hierarchy and the next lower level;

(ii) the exit screen in the normal navigation mode;

(iii) the selection of the elements that trigger the function to re-calculate the route;

(iv) set the current location as the position to be marked on the map.

This approach can be illustrated in several contexts. First, to facilitate access to the functions that enable the calculation of alternative routes through the menu location of the graphic icons for these functions (or any other way that allows selection of functions, such as lists, independent switches etc) on the menu screen, to which you have easy access to the main navigation screen, i.e. the screen that is displayed during an actual or simulated/preview navigation (see figure 1 or 2). As mentioned above, in the normal mode navigation device displays a moving map that shows the position of the navigation device while driving. Touching the map (i.e. touch screen) once (or twice in another embodiment, the near center of the screen (or any part of the screen in another embodiment, the) calls menu recalculation (see figure 3) with large icons corresponding to different functions re-calc the tion of the route, such as the calculation of an alternative route; recalculating the route, so as to exclude the following part of the street (useful in case of obstacles or large tube); and re-calculating the route with the exception of specific listed streets. These functions calculate an alternative route run by touching the appropriate icon on the menu screen recalculation (which is the one the user interacts with the system, such as touching the screen off screen normal navigation mode). Access to other functions recalculate the route, you can get at a lower level menu structure. However, they all achieved by selecting the elements such as graphical icons, lists, independent switches that are uniquely linked to areas of the touch screen, which are large enough to let the user select them with your finger while driving, they are usually at least 0.7 cm2.

Virtual keyboard

As mentioned above, a key characteristic is the use of large areas of the touch screen for each graphical icon that triggers the basic function that the driver may be performed by the automatic control is Biel. This approach is also used for the keys of the virtual keyboard (for example, ABCD format, as shown in figure 4, the QWERTY format and so on). Because the device can display large alphabetic keyboard, much larger than a normal keyboard-based screen in the PDA, it allows the user to enter text more easily and without removing the device from the support or the dashboard and even using your finger instead of a pen.

The optimal size of the iPaq device (240×320 pixels or 106 pixels per inch, or 48 pixels 1 cm) consists of:

for images QWERTY/ AZERTY:

horizontal distance: 25 pixels from center to center (from key to key),

vertical length: 32 pixels from center to center (from key to key);

for images of the keyboard ABC:

horizontal distance: 40 pixels from center to center,

vertical length: 32 pixels from center to center.

Note: the image of a numeric keypad is a mixed (both small and large keys). In addition, some keys can be 1 pixel smaller in width than the other keys (for aesthetic reasons), so the distance between the centers can be different in different keys.

The size of the individual keys in pixels (width, height) is:

36×28 (image klaviatur the s ABC),

21×28 (image QWERTY/AZERTY),

46×28 (arrow images QWERTY/AZERTY),

70×28 (the return key and space images QWERTY/AZERTY).

Note: some keys can be 1 pixel smaller in width than the other keys (for aesthetic reasons).

Overall dimensions (width, height) images of different keyboards is:

240×155 (image keyboard ABC),

240×155 (image QWERTY keyboard),

240×155 (image keyboard AZERTY),

240×62 (image 2 digital lines/arrow keys),

240×31 (image 1 line arrow keys).

Note: including white field with a width of 1-3 pixels.

These dimensions allow you to display a programmable keyboard that the user can easily operate with one finger when the device is mounted on a support dashboard when the vehicle is moving and without significant distraction from driving.

The tolerances on the above dimensions are approximately 25% (plus or minus).

Waypoint

If the driver passes the points of interest on the street (e.g., while driving), then he can save the information about this location, using a very simple action, such as a quick double-tap to the specified area on the screen, this ka is the area size of 0.7 cm 2located in the center of the current position of the vehicle, the display device (or submission of a voice command). This saves the label in database track points; essentially coordinates interesting places. This is another example of the basic functions (refer to the current location as a waypoint), which is run using the area of the touch screen, large enough to ensure reliable selection using your finger even during the control by the user of the vehicle. A waypoint can also be noted on the map as an icon POI (interesting point). Later the user can retrieve and use it (or annotate it and save). For example, if the place is designated as an interesting point on the map, the user can choose an interesting point on the map that leads to the opening of the window for the annotation, in which the user can enter text (for example, "big bookstore").
