Gesture Signal Processing and Music: Difference between revisions

Revision as of 07:24, 12 October 2009

What is a gesture? Physical. Bodily: hands, face, posture. Non-verbal. What do gestures communicate? Is a gesture more like a button or a handle?
What is a musical gesture?

Camera-based
- 2D image processing
- 3D Motion Capture using many cameras
Goniometry: measuring joint angles with physically attached sensors
- Laetitia Sonami's Lady's Glove: http://www.youtube.com/watch?v=HYTrNOmSRSo&feature=player_embedded
Electromyography: measures muscle activation by measuring electrical activity
- Pamela Z's controller (which I believe uses emg): http://www.pamelaz.com/VociMov.html
With accelerometers attached to the body (e.g. wiimote, iphone)

Position: x
Velocity: v = dx/dt
Acceleration: a = dv/dt
- Proportional to force (Newton's 2nd law of motion: F = ma )
Jerk: j = da/dt
