Abstract
The invention discloses a method for implementing a wireless mouse by the aid of laser straight rays. The method particularly includes that on a projection demonstration panel or a liquid crystal television set or a display is provided with a laser receiving device with a certain quantity of miniature laser sensors, the miniature laser sensors are arranged in an X-direction and a Y-direction, the wireless mouse in the hand of a user is a mouse capable of emitting the perpendicular laser straight rays, the crossed laser straight rays can be projected on the miniature laser sensors on the laser receiving device along with movement of the mouse, and position coordinates of received laser straight rays can be continuously coded and are transmitted to a computer host via wireless interfaces.
Description
Technical field
The present invention relates to wireless mouse, the interaction of projection demonstration system is hand-written, touch-screen, and for fields such as the amusement light guns in computer game and commercial game machine, is reform the one of these devices existing.
Background technology
Existing wireless mouse, can be divided into three classes substantially:
The first kind is that mouse has a set of wireless launcher, be used for launching the X of mouse, the information of Y-coordinate and button, host computer then has a corresponding radio receiver to be responsible for acceptance, the wireless mouse of this type, only reach the function of that line removed between mouse and computer, the function of " indication is namely shown " that real wireless mouse has can not be realized.Use this wireless mouse, user still must rely on mouse pad and desk, and wrist posture is fixed, easily tired, directly affects the authenticity of game and recreational.
Equations of The Second Kind wireless mouse, be launch a laser spots by wireless mouse, receiving trap is a picture position sensor.If the patent No. is CN201120569209.1 " a kind of wireless laser pen with air mouse function ", disclose one and utilize laser spots, project on the sensor of picture position, then draw coordinate position by the laser spots detected above position transducer; Also have the patent No. to be 201210026754.5 " controlling the mouse system of projection demonstration based on laser pen ", also disclose one and project camera by laser spots, catch laser spots through camera, then realize location by algorithm.The wireless mouse of this type, although the effect that can reach " indication is namely shown ", but, the difficulty no matter realized from cost is not only complicated but also expensive.
3rd class wireless mouse realizes its location object by gyroscope, and it is more complicated that it realizes principle, and cost is higher, and positioning precision is not high.
Secondly, widely used light gun in computer shooting game fan at present, it is also the one expansion of wireless mouse application in essence.Such as, amusement light gun on the PS2 of Japan, its principle of work is also rather complicated, and it is by Games Software, and main control system realizes the location of coordinate position.For NTSC, after user presses the trigger of light gun, Games Software main control system sends a hololeucocratic frame, it is need from top to bottom that televisor shows this white frame, scan from left to right, so from this frame scan first point, receive this mistiming of white light T (pos) to muzzle, just can calculate coordinate position.If all situations (scan-hidden, flyback, effective scanning line etc.) is considered, computation process wants complicated a lot, and the cost of realization is quite high.And old televisor, the televisor of lining by line scan, also has projection screen can not be suitable for this kind of light gun.
Summary of the invention
In order to solve the problem, the present invention neither adopts the method for PS2 amusement light gun, laser spots is not adopted to coordinate imageing sensor yet, and gyrostatic method, but adopt two bundle orthogonal laser rectilinear(-al)s coordinate system, to with Y-direction, the laser receiver of miniature laser inductor is all housed in conjunction with an X, forming one can be remote, and pinpoint wireless mouse system, without the need to contact screen, just can reach the object of long distance positioning, carry out alternative above product.The technical solution adopted in the present invention is: at projection demonstration plate, LCD TV, touch-screen or computer screen, installs a laser receiver, and this laser receiver has the X-direction of some and the miniature laser inductor of Y-direction arrangement.And " wireless mouse " in user's hand, it is then a mouse that can send the mutually perpendicular laser straight line of two bundles, along with the movement of this mouse, miniature laser inductor above laser receiver, is constantly undertaken encoding and sending host computer to by wave point by the Cross hair laser linear position coordinate received.
The present invention program compares with PS2 amusement light gun with the wireless mouse of above three types, has and is easy to realize, registration, reliable and stable, cheap, the advantages such as remote control distance is far away.And realize location by remote laser straight line due to the present invention, directly do not contact with screen, the specific common fault of wearing and tearing of general touch-screen can be avoided, thus may be used for alternative various forms of touch-screen.

Embodiment
In FIG, when user presses wireless mouse switch 1., wireless mouse 1. can produce vertical laser straight line 2. with horizontal laser light straight line 3., be radiated on computer screen, and at the upper side frame of computer screen and lower frame, 800 miniature laser inductors are all installed, the left frame of computer screen and left frame are provided with 600 miniature laser inductors, and in other words, the resolution of embodiment of the present invention wireless mouse is 800 x 600.Whenever vertical laser straight line be 2. radiated at or some positions of lower frame time, inside frame, corresponding miniature laser inductor can produce a signal connected or disconnected, show vertical laser straight line 2. now residing X square to position coordinates, similarly, when 3. horizontal laser light straight line is radiated at some positions of left or right frame, miniature laser inductor inside corresponding frame also can produce a signal connected or disconnected, show the position coordinates of the Y-direction that horizontal laser light straight line is 3. irradiated, like this, at synchronization, the frame of computer screen just can know the coordinate position that 1. wireless mouse in user's hand will point to whenever and wherever possible, along with the movement of the 1. constantly up and down or left and right of the wireless mouse in user's hand, 2. and 3. mutually perpendicular two bundle laser straight lines also constantly to irradiate the miniature laser inductor of relevant position of screen frame, constantly produce simultaneously and connect or disconnect signal, these signals send host computer to by wave point after being encoded by scrambler.
In fig. 2, when 1. the wireless mouse in user's hand points to the upper left corner of computer screen time, pass through Fig. 4, we can be clear that 7. 2. vertical laser straight line be radiated at X-direction the 25th miniature laser inductor inside upper side frame, this miniature laser inductor can produce a signal connected or disconnected, show vertical laser straight line 2. now the X-coordinate of present position be 25, simultaneously, pass through Fig. 4, we also can be clear that 6. 3. horizontal laser light straight line be radiated at Y-direction the 9th miniature laser inductor inside left frame, this miniature laser inductor also can produce a signal connected or disconnected, show horizontal laser light straight line 3. now the Y-coordinate of present position be 9.Like this is exactly, and the coordinate of the screen position that we can learn pointed by wireless mouse is (25,9).
Similarly, in figure 3, when the wireless mouse in user's hand points to the lower right corner of computer screen time, by Fig. 5, can see that the coordinate of the screen position pointed by wireless mouse is (786,590).
The wireless mouse of illustrated example; a just application special case of the present invention; purposes of the present invention, except may be used for wireless mouse, touch-screen; projection is interactive hand-written; amusement light gun etc., the holder of patent can also to the present invention in claims limited range, does further technological improvement and perfect; and develop associated application, also should be included within protection scope of the present invention.
