1. Pressure
2. Light
3. Proximity
4. Acoustic
5. Tilt
6. Motion
7. Orientation

b. Overview of Multi-touch Systems
i. Resistive
ii. Surface Wave
iii. Capacitive/Dielectric
iv. Infrared
v. Vision Systems
1. FTIR - Frustrated Total Internal Reflection
2. DI – Diffused Illumination
a. Front
b. Rear

6. Deciding When to Use a Gesture-Based System
a. Inappropriate for:
i. Heavy Data Input
ii. Reliance on The Visual
iii. Reliance on The Physical

b. Appropriate for
i. More Natural Interactions

  1. I don't think we have the gestures down for bathroom interactions. If you find yourself traveling quite a bit, you know what I mean.

    You have to do a little toilet dance to get the thing to flush in one restroom, and in another, just reaching for the toilet paper will give you a huge surprise.

    And then you need to learn a variety of other dances to figure out how to turn on the hot water, get some liquid soap, and dry your hands.

    We need to look more at affordances (no pun intended).
