Demo - Fingertip Tracking for Different Gestures
Gestures are defined for the use of building 3D CAD model without mouse.
For example, first, a 3D block is built in the CAD environment, then different gestures correspond to different operations on the 3D block as explained below.
move the block to another coordinates
rotate the block along the fingertip's moving direction
zoom in the current workspace for more detailed modeling.
Fingertips are marked by red dot, and red arrow pointing along its orientation.
Green circles corresponds to estimated fingertip radius.
