Questions:

1. In the video, I talk about the types of mechanoreceptors that are found in the skin. Do a search on the Internet and find which types there are. Please don't cut-and-past your answer, but give a short overview.
2. In the video, I talk about the tight coupling between sensing and action within the haptic sense. How is this interaction loop influenced by other sensory information gathered from the interaction?

Question:

1. Given the variation in haptic "resolution" on different parts of the body, discuss how and where would you construct a "haptic HUD" for information such as:
   
   1. a map for navigating to an objective in an FPS,
   2. the number of laps you've completed in a racing game, and
   3. the action of picking up a health pack.

Questions:

1. What do you see as the main tradeoffs between active and passive haptic feedback?
2. Do you think sensory substitution as it is commonly used in games is effective?
