Time-to-Adoption: Four to Five Years
It is now practical to produce computers that can make decisions based on contextual clues, such as what the user is attending to, the user's location and orientation, what the user is focused on, the date and time of day, lighting conditions, other objects or people in the environment, accessible infrastructure in the immediate vicinity, and so forth. The implications are only beginning to be explored, but may be profound. Context-aware computers can interact with the user or can program themselves to have particular responses appropriate to a situation; for example, to lower the volume of music being played when a telephone rings nearby, or to silence all calls during a meeting or class.

Relevance for Teaching, Learning & Creative Expression
- allow tailored presentation experiences; for instance, automatic adjustment of lighting, sound, and projector brightness as faculty moves through a lecture (brighter lights on the faculty when s/he steps away from the screen, or brighter projection when his/her attention returns to it)
- identify the teacher and enable him/her to control projection, lighting, and other room features from anywhere in the room
- deliver information relevant to the learner's location (in a library, museum, or other physical space)
Examples
- Tsinghua University has developed a smart classroom that incorporates pervasive computing technologies to sense where learners are in the physical space, what they are doing, and what they may need. The lecturer controls the display with voice and gesture.
- The context-aware cell phone project at MIT is attempting to build a wearable cell phone which will receive signals about the user's location and behave appropriately (turn themselves off, for example). In a prior MIT project, researchers developed a phone that acquired data about whom the user knows , where the user goes, and what the user habitually does, and then can give the user feedback based on the information it collects. http://www.eurekalert.org/pub_releases/2004-11/ns-tpt112404.php
