    • The present invention discloses a method and apparatus for controlling an object movement on a screen. The method senses a first change in a position of a pointing device in a coordinate system to obtain a first displacement, and controls the object movement by a first displacement output ratio according to the first displacement. The method senses a second change in a position of the pointing device in a coordinate system to obtain a second displacement, and controls the object movement by a second displacement output ratio when a difference between a direction of the first displacement and a direction of the second displacement exceeds a first angle threshold, wherein the second displacement output ratio is lower than the first displacement output ratio.
    • 本发明公开了一种用于控制屏幕上的物体运动的方法和装置。 该方法感测坐标系中的指示装置的位置的第一变化以获得第一位移,并且根据第一位移来控制物体移动第一位移输出比。 该方法在坐标系中感测指示装置的位置的第二变化以获得第二位移,并且当第一位移的方向与第二位移的方向之间的差异时,控制物体移动第二位移输出比 位移超过第一角度阈值,其中第二位移输出比低于第一位移输出比。

    • An interactive image system includes a host generating interactive images; a light source generating at least one light beam; and an interactive control device transmitting data to the host and switching between an operation status and an idle status. The interactive control device includes: an image sensor capturing a first picture in the idle status, wherein the first picture has a reference point image formed by the light beam; and a control circuit selecting a pixel area according to the position of the reference point image in the first picture, controlling the image sensor to obtain a second picture according to the pixel area, and comparing a threshold value with the brightness information of at least one pixel in the pixel area of the second picture to confirm whether the interactive control device is still in the idle status.
    • 交互式图像系统包括生成交互图像的主机; 产生至少一个光束的光源; 以及向主机发送数据并在操作状态和空闲状态之间切换的交互控制装置。 交互式控制装置包括:图像传感器,其捕获处于空闲状态的第一图像,其中所述第一图像具有由所述光束形成的参考点图像; 以及控制电路,根据所述第一图像中的所述参考点图像的位置选择像素区域,根据所述像素区域控制所述图像传感器以获得第二图像,并且将阈值与至少一个的亮度信息进行比较 像素在第二图像的像素区域中,以确认交互式控制装置是否仍处于空闲状态。
