A kind of automatic navigator that does not have hard button
Technical field
The invention belongs to the vehicle mounted guidance technical field, relate to a kind of automatic navigator that does not have hard button, particularly a kind of automatic navigator that replaces hard button with touch-screen.
Background technology
Usually; Traditional automatic navigator all needs a plurality of button layouts on housing; The result makes that more extra button influences are attractive in appearance on the product appearance; Particularly similar android operating system, much all need " homepage ", " returning ", " menu ", and " closing " several hard buttons accomplish complete system operation.Caused based on the automatic navigator outward appearance of android system plain, if but hardware on do not support these buttons, can cause a lot of third party applications can't use or system works undesired.Therefore, press for a kind of solution that can take into account the normal operation of attractive in appearance and system.
Summary of the invention
The present invention is in order to make existing automatic navigator more attractive in appearance and do not influence the normal operation of system again; Designed a kind of automatic navigator that does not have hard button; Replace the various hard push-botton operation on the present hardware configuration with touch-screen; Realized zero firmly by key technology, the two can perfectly combine thereby realize the attractive in appearance of product appearance and operation practicality.
The technical scheme that the present invention adopts is: a kind of automatic navigator that does not have hard button; Comprise the housing that is provided with command input device, output display screen in the structure; And the central processor CPU of supporting setting on the enclosure interior circuit board, display driver circuit, and GPS communication unit; Key is: described command input device is based on the soft keyboard of touch-screen input; On circuit board, set up and store " homepage ", " returning ", " menu ", and start self-starting private memory, touch location detection circuit, the touch signal coding circuit of " closing " four soft-key button groups menu; The output terminal of touch signal coding circuit, display driver circuit, and the GPS communication unit link to each other with the data bus of CPU respectively, comprise in the method step based on the no hard button of above-mentioned navigating instrument realization:
A, starting up, CPU visits private memory, the soft-key button group menu of storing in the private memory is carried out the soft-key button window show in touch display screen;
B, touch location detection circuit touch operation according to user's the hand in the soft-key button window to carry out the position and catches, detects, and position detection signal is sent to the touch signal coding circuit;
C, touch signal coding circuit are encoded, and the signal behind the coding is sent to CPU handles;
Signal after D, CPU handle by display driver circuit, and display screen export demonstration.
The invention has the beneficial effects as follows: import through touch-screen; Use the virtual soft dish to substitute the hard button of layout on hardware configuration; Realized based on android operating system zero firmly by key technology, the user through click software push buttons on the virtual soft dish accomplish with hardware button on the same function; The user can show in needs or hiding software push buttons group simultaneously; And the user position that can arbitrarily move the software push buttons group to be adapting to the layout at each different application interface, thus realize the attractive in appearance of product appearance and operation practical the two can perfectly combine.

Embodiment
A kind of automatic navigator that does not have hard button; Comprise the housing that is provided with command input device, output display screen in the structure; And the central processor CPU of supporting setting on the enclosure interior circuit board, display driver circuit 4, and GPS communication unit; Importantly: described command input device is based on the soft keyboard 1 of touch-screen input; On circuit board, set up and store " homepage ", " returning ", " menu ", and start self-starting private memory 6, touch location detection circuit 2, the touch signal coding circuit 3 of " closing " four soft-key button groups menu; The output terminal of touch signal coding circuit, display driver circuit 4, and the GPS communication unit link to each other with the data bus of CPU respectively, comprise in the method step based on the no hard button of above-mentioned navigating instrument realization:
A, starting up, CPU visits private memory 6, the soft-key button group menu of storing in the private memory is carried out the soft-key button window show in touch display screen;
B, touch location detection circuit 2 touch operation according to user's the hand in the soft-key button window to carry out the position and catches, detects, and position detection signal is sent to touch signal coding circuit 3;
C, touch signal coding circuit 3 are encoded, and the signal behind the coding is sent to CPU handles;
Signal after D, CPU handle by display driver circuit 4, and display screen export demonstration.
Soft-key button group menu carries out window window displayed attribute in touch display screen be can be by the top-level windows that any other window covered.
Described automatic navigator is the serial automatic navigator of smooth peace that Lu Chang company produces.
The operating system of automatic navigator is android operating system.
When concrete the use; During this automatic navigator of starting up; CPU visits private memory; With " homepage " stored in the private memory, " returning ", " menu ", and " closing " four soft-key button groups menu load and be presented at top-level windows, this window can not covered by any other window.The touch click event of its region is all handled by soft-key button group menu.This soft-key button group menu floats on other all windows, and is all effective to guarantee on any Application Program Interface.
When the user feels when some Application Program Interface do not need to feel this window; Can close it by the X button of soft-key button group by selected element; The soft-key button group window will be removed out this moment, on screen, will hide this soft-key button group menu, like movie interface or interface.
When the user need show that soft-key button group menu is operated again behind hiding soft-key button group menu; Can eject soft-key button group menu through on screen, using specific gesture operation, this kind situation is generally used for releasing to be used or shows the application setting option and get back to sight such as main interface.
When the user when some scene need move this soft-key button menu; It supports the user to drag any position of soft-key button group menu to screen with finger; The user only need pin and move to assigned address behind the soft-key button group menu and unclamp; Soft-key button group menu will be moved to assigned address, and finger when moving soft-key button group menu also move thereupon.To carry out the self-adaptation operation for screen simultaneously; When moving to the top of screen or bottom, soft-key button group menu carries out horizontal layout automatically and shows, when moving to left or during edge, the right; Soft-key button group menu carries out vertical layout automatically and shows, with user-friendly attractive in appearance with demonstration.
When the user need dwindle this soft-key button group menu when showing in some scene; It supports to minimize function; The user click the soft-key button group minimize button after soft-key button group menu will be shown as a small icon in the fixed position of screen; This small icon also exists and can be covered by any other window as the top-level windows of screen always, like this when the user at any interface when whenever clicking this small icon, soft-key button group menu will get location restore before hiding and normally shows original.
