Gesture and Measuring Movement

  • 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?

Techniques for measuring human movement

Really basic physics

  • 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
