EXERCISE 21.6 [extra - not in book]

Chapter 2 of Human-Computer Interaction explores a number of traditional input and output devices. The pace of technological change means that such an exploration will always be incomplete. This exercise asks you to conduct a search on the Web to uncover information about novel (at least novel to you) input and output devices.

For each device (one input, one output) produce a short description of its function, web references for more information and, if possible, information on vendors for the product.
