Hi. I want to implement a mouse using a webcam. I would be tracking a laser pointer dot using a webcam and converting that point to mouse coordinates. I want to develop a java application for it. I am a beginner in java so i would be very thankful if you please help me out with the following:

- How to launch a java application at startup in windows and linux?
- How to stream live video from a webcam in java?
