Camera Mouse

Introduction


•Alternative mouse is widely used for disabled people.
•Camera mouse can be implemented either in embedded system or on PC.
•LED pointer can be fixed anywhere on users to provide them the most convenience.

Embedded System Hardware Design



Algorithm design


Tracking Demo On PC(to verify the algorithms)


The small square under the LED pointer shows the tracking result. To verify the algorithms, I did a test in another environment which was darker. The demo is shown:

Hardware Test Result

•Test Step: Nios saves one image from Hardware into a text file, and send it to PC. The result is plotted by Matlab as below.
