Project update

Time goes so fast, it's already the 5th week! For my project, I finally linked the pd tracking program to control the real mouse cursor that can move around and make click by staying at a same point for a few seconds. However, there are still some problem need to be solve. When I tested it, I found that there are some positions that can't be reached by the tracking control. This is because I translate the rather small head movement space into much more bigger screen cursor movement space by multiply it to some ratio. The example below shows how this gap happened. The ratio in this example is 3, when the tracked target moved from the blue pixel to the green pixel, the movement are enlarged so there will be two pixels jumped (but it's almost unnoticeable on the screen).

This gap is a trade off between movement sensitivity and control, the smaller the gap the more we had to move our head. For now, the ratio is around 7 to 20, still try find a balance.
