Existing all-in-one is incorporated into main frame, display and various output input device together, and the inner member height is integrated, and machine has only a power lead; All-in-one because of its brief wireless, save advantages such as space, the integration that overflows, energy-conserving and environment-protective, trend outward appearance, special purpose computer field in public places is subjected to market and welcomes; And at present a lot of all-in-one adopts touch-screen to realize, also some integrated keyboard and mouse; Touch-screen, keyboard and mouse are the input equipments of contact.But all-in-one generally is placed on the public place, if frequently touched or press, damage easily, and the maintenance cost height, simultaneously many finger contacts are unhygienic, spread disease easily.
Summary of the invention
Technical matters to be solved by this invention is to need to realize that all-in-one is carried out contactless gesture to be controlled, and to prolong the serviceable life of all-in-one, improves user's experience, has also overcome a sanitarian difficult problem simultaneously effectively.
To this, the invention provides a kind of all-in-one of supporting gesture identification, comprising:
Outer electrode;
Electric field induction gesture identification module, described electric field induction gesture identification module comprise that the 3D based on electric field induction follows the tracks of and the gesture controller chip, and described electric field induction gesture identification module is connected with outer electrode;
Main frame, described main frame converts the electric field induction signal in the electric field induction gesture identification module to by the gesture instruction modular converter control signal of system command, to preestablish and the gesture storehouse of process checking and the coupling between the system command to finish, described gesture instruction modular converter operates on the driver of 3D tracking and gesture controller chip; And,
Display, described display is connected with main frame.
The present invention is suitable for the special purpose computer field of public place, for example show and use, the user is usually also uncomplicated alternately with the all-in-one of supporting gesture identification, and the operation of using morely is that picture is dwindled in page turning up and down or amplification, can substitute these uncomplicated operations with certain gestures; The simplest hand of brandishing up and down for example, corresponding page turning up and down; Finger opens gathering, and corresponding the amplification dwindles picture etc.And at the application of mutual complexity, also can keep display and be mode such as touch-screen to import, function commonly used replacements that can use gesture is to reduce the touch number of times.
The all-in-one of support gesture identification of the present invention is a kind of special purpose computer, be used for satisfying the application-specific demand of particular place, this all-in-one is incorporated into main frame, display and various output input device together, the inner member height is integrated, machine has only a power lead, the present invention is applied in Gesture Recognition in the all-in-one, proposes the all-in-one of the support gesture identification of the contactless operation of support, can control running software by gesture.
The present invention adopts the configurable 3D based on electric field induction to follow the tracks of and gesture controller chip realization electric field induction gesture identification module, and then the all-in-one of gesture identification is supported in realization, wherein, integrated main frame, display, outer electrode, electric field induction gesture identification module and output input device in the all-in-one of described support gesture identification; Outer electrode is connected with electric field induction gesture identification module, and electric field induction gesture identification module preferably links to each other by USB with main frame; Display can adopt touch-screen; Output input device, for example loudspeaker, camera, keyboard and mouse etc. determine according to specific application demand whether needs dispose, and if desired, can allow all-in-one keep traditional input-output operation mode, realize the support to gesture identification simultaneously; If do not need, then do not dispose.In a word, output input device disposes according to application demand.
Described main frame converts the electric field induction signal in the electric field induction gesture identification module to by the gesture instruction modular converter control signal of system command, to preestablish and the gesture storehouse of process checking and the coupling between the system command to finish, described gesture instruction modular converter operates on the driver of 3D tracking and gesture controller chip; Predefined gesture storehouse and system command are one to one relation, and each is all unique corresponding with system command by the gesture of checking, to realize controlling the all-in-one of supporting gesture identification by control signal.
In other words, namely described gesture storehouse is predefined gesture and system command instruction set one to one, is used for the gesture that identifies is converted to corresponding instruction and execution.This gesture storehouse is pre-set, makes in actual use, and is effective more fast for the identification meeting of gesture; Preferably, self-defined setting can be carried out according to user's demand in this predefined gesture storehouse, and sets shortcut.Tourist attractions are introduced and the all-in-one of the support gesture identification that map is checked as being used for, recommending scenery spot and map guide and are to use the very high function of frequency, the present invention can fixing gesture be opened recommending scenery spot as shortcut and map guides by setting, be very beneficial for visitor's operation, and prolong the serviceable life of all-in-one, improve user's experience, also overcome a sanitarian difficult problem simultaneously effectively, especially under particular environment, brought good beneficial effect.
