推荐答案

1. 在没有木板或家具的墙壁之前是理想的.
2. 将网络摄像头对准墙壁，并保持一定距离，以使理想情况下，所有墙壁都被网络摄像头图像覆盖.
3. 让程序从摄像机读取视频流，并进行分析以识别单击，双击，定位甚至手势.

读取视频流并从中读取帧将非常简单，也许可以在这里找到:多功能WebCam C#库 [ ^ ].由于激光笔很亮，并且大多数都具有独特的颜色，因此获取激光点在框架上的位置也不会造成问题.如果您的激光笔有一个可以打开和关闭的按钮，则可以轻松地模拟鼠标.将激光关闭一定的TBD时间将被记录为单击，双击也是如此.激光再次重新亮起时，应同时触发咔嗒声和双击声.

Reading of a video stream and fetching the frames from that would be pretty much straight forward and maybe can be found here: Versatile WebCam C# library[^]. Since laser pointers are rather bright and mostly have a distinctive color fetching the position of the laser dot on the frame should also pose no problem. If your laserpointer has a button with which it can be turned on and off you could easily emulate the mouse with that. Turning the laser off for a certain TBD amount of time would be registered as a click and the same goes for the double click. The click as well as the double click should be triggered when the laser finally comes back on.
