EXERCISE 20.7 [extra - not in book]

'Ubiquitous computing suggests that the interface itself can take on the responsibility of locating and serving the user'. In the past, adaptive user interface systems have struggled to get enough information about the user.

Will ubiquitous computing mean that users have to spend all their time telling the computer what they're doing? Consider various current commercial and research ubiquitous computing devices. Find out

(i) to what extent they embody knowledge about the user's location, tasks, etc.

(ii) how they discover this contextual information

(iii) whether you think they do this in a way that is is sufficiently unobtrusive for the user.

(The eClass project in the Future Computing Environments group at Georgia Tech, http://www.cc.gatech.edu/fce/eclass/, studies the impact of ubiquitous computing on education.)
