The Interface and Wheel
Haptic Wheel

Haptic Interface

  • Enables human/computer interaction through sense of touch
    • Force feedback
    • Virtual reality simulators (flight, driving)
    • Training (surgery, assembly)
    • Teleoperation (manufacturing)
  • Human visual sensor: 30 Hz
  • Human haptic sensor: 500 Hz - 1 kHz
  • Ideal pedagogical tool...
    • Student satisfaction
    • Virtual reality algorithms easy to understand
    • Tricky to get right

Haptic Wheel

  • Developed by Professor Brent Gillespie, Mechanical Engineering Department, University of Michigan
    • DC motor
    • PWM amplifier with current controller
    • Optical encoder
    • 128/18 gear ratio
