Pinch Recognition Using Finger Zones

A non-transitory computer readable medium comprising computer readable code executable by one or more processors to:

• obtain hand tracking data based on one or more camera frames;
• detect a contact event between a first finger and a second finger based on the hand tracking data, wherein the contact event corresponds to a first gesture;
• determine, on the first finger, a first contact location where the first finger makes contact with the second finger;
• determine, on the second finger, a second contact location wherein the first finger makes contact with the second finger;
• and
• in response to a determination that the first contact location is within a first region of a predefined gesture zone for the first gesture and the second contact location is within a second region of the predefined gesture zone for the first gesture, enable a gesture-based input event corresponding to the first gesture.
