[finger tracker PIC] Chapter VBI-7.   Finger Tracking with TopCodes


This chapter does not appear in the book.


This chapter describes how to implement finger tracking using TopCode markers. The objective is to use a webcam to track finger movements, employing them as the equivalents of mouse moves and button presses inside an application (shown above).

The movement of my fingers shown in the webcam image on the right of the screenshot causes the crosshairs image to move and change in the panel on the left.

This doesn't use all the functionality offered by TopCodes, so I'll also spend some time explaining how to access and utilize those other features.
