指针定位系统
摘要：
一种指针定位系统，包含有一影像形成装置、一光点产生装置、一操控装置、一运算电路以及一主机；该影像形成装置用以于一显示区域上形成影像；该光点产生装置用以于该显示区域上形成复数光点；该操控装置与该光点控制装置电性连接，用以指向该显示区域、并撷取具有部分该些光点的影像；该运算电路依据撷取的影像运算出该操控装置所指向于该显示区域上的位置；该主机依据运算的结果输出讯号给该影像形成装置，以于该显示区域上形成对应的影像。
摘要（英）：

Disclosed is a pointer positioning system. The pointer positioning system comprises an image forming device, a light spot generating device, a control device, a computing circuit and a host. The image forming device is used for forming an image in a display area; the light spot generating device is used for forming a plurality of light spots in the display area; the control device is electrically connected with the light spot generating device for pointing at the display area and capturing the image provided with parts of the light spots; the computing circuit computes the position pointed by the control device to the display area according to the captured image; the host outputs signals to the image forming device according to computed results for forming a corresponding image in the display area.
