EXERCISE 20.6 [extra - not in book]

What is the difference between an ambient display and a peripheral display? Suggest some designs for ambient displays for use in a university environment.

answer available for tutors only

Ambience in this sense is a relationship between the display and its nearby environment. Peripheral is a relationship between a display and a user who might view the display. To be peripheral is to be outside the main focus of attention (in the background versus in the foreground). Effective design of an ambient display would allow for it to be in the periphery except when it reflects some important change of information it is reporting.

The design portion of this question is fairly open-ended and could be addressed as a group project. The HCI literature from the late 1990's has had many suggestions for ambient or peripheral displays, and even some work on how to evaluate their effectiveness.
