Detailed description of the invention
For making the purpose of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
Refer to the flow chart that Fig. 1, Fig. 1 are tv wireless sky Mus cursor location method preferred embodiments of the present invention.As it is shown in figure 1, described tv wireless sky Mus cursor location method, including step:
Step S100, each menu area of menu area multiple on screen is all divided into many sub regions, and each subregion is arranged corresponding change in displacement coefficient.
In presently preferred embodiments of the present invention, before moving when empty Mus wireless described in user operation, the multiple menu area on screen are each divided into many sub regions, and namely each menu area is at least divided into two sub regions.After completing the division to menu area, each subregion is arranged corresponding change in displacement coefficient, and the change in displacement coefficient being positioned at all subregions of same menu area is different from.
Described change in displacement coefficient is that namely wireless empty Mus light is marked on the motion sensitivity in this region for determining the parameter that wireless empty Mus light is marked in this region mobile accelerated factor.
Owing to each menu area in telescreen has been divided into multiple region all in advance, and each region is all provided with different change in displacement coefficients, therefore the bigger region of wireless empty Mus light is marked in screen change in displacement coefficient is moved comparatively fast, the region that change in displacement coefficient is less in screen is moved slowly.
Step S200, obtain the mobile displacement of wireless empty Mus, and described mobile displacement is changed into, by default linear scale, the location variation that wireless empty Mus light is marked on screen.
In presently preferred embodiments of the present invention, when user manipulate wireless empty Mus aloft move time, the mobile displacement of wireless empty Mus namely the actual amount of movement of wireless empty Mus can be obtained.Owing to being move in a three dimensions when wireless empty Mus is aloft moved, historical facts or anecdotes border amount of movement vector is a three-dimensional vector when characterizing.Wireless empty Mus cursor both can be move on the two dimensional surface in two-dimensional picture screen simultaneously, it is also likely to be on the three-dimensional planar in three-dimensional picture screen and moves, therefore the mobile displacement of wireless empty Mus is converted into the location variation that wireless empty Mus light is marked on screen, linear transformation need to be carried out.
Such as, when TV is two-dimensional picture, can set up one with a certain right-angle side intersection point of telescreen be zero O, with telescreen be XOY plane, be perpendicular to telescreen and be Z axis through the straight line of zero O rectangular coordinate system in space.Now when user manipulates when wireless empty Mus is aloft moved from A(xA, yA,zA) move to B(xB, yB,zB), then the mobile displacement of wireless empty Mus is (xB-xA, yB-yA,zB-zA), when its linear transfor is the actual amount of movement that wireless empty Mus light is marked on screen, by (xB-xA, yB-yA,zB-zA) orthographic projection is to XOY plane, namely have ignored wireless empty Mus movement in the Z-axis direction.
Obviously, when in TV being three-dimensional picture, then the linear scale passing through to preset is by the mobile displacement (x of wireless empty MusB-xA, yB-yA,zB-zA) it is converted into the location variation that wireless empty Mus light is marked on screen.When being embodied as, the linear scale preset in step S200 is 0.5-5.Best, described linear scale is 1, namely the mobile displacement of wireless empty Mus is equal with the actual amount of movement that wireless empty Mus light is marked on screen at the orthographic projection component of telescreen.
