Currently the hand should not be farther away than 100 - 120 cm from the Kinect to reliably detect fingers. Should the Microsoft Kinect SDK (or another driver, or even another device) offer better resolution, then hands and fingers could also be detected farther away.
Plans for the weekend
- Find the center of the palm (in addition to the center of the whole hand cluster)
- Improve hand and finger detection performance
- Hand detection without fixed depth segment
