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
