Control your computer using a laser or IR pen.

Step 4 Final Adjustment

After you adjust everything, go into control panel, and folder options, and make it so you can open things with only one click, because the program only currently clicks once. After that, check the boxes control cursor and enable click. Now, your laser or IR pen will control the cursor and click. Just make sure if you are using a laser, the webcam is pointing at the wall and for an IR pen, you have it pointing towards you and the image mirrored. Move the IR pen around away from the screen and the cursor will move. Move the laser around on the wall where the camera can see it and the cursor will move around.Now there is no need for a mouse. Please vote for me, as I put a lot of work into this instructable. It's not as accurate as others like the ones using wiimotes, but it works.
