Supporting automated systems will therefore have to take into account varying levels of specification, autonomy, complexity, and the interactions among them. This context scope is an example of individual preferences. People can be expected to have preferences for every aspect of their interactions with computer and communications systems. Those preferences will include the permissible demotions they will allow in different locations. An example of a permissible demotion is having an e-mail message read over the telephone.
Graphic information is lost, but the message is conveyed.
Other preferences might include what contexts could be established from what locations and what level of security would be involved. These are examples of applying preferences to the communications channels and devices available at different locations. They illustrate the interaction between context, preferences, and location. Finally, individuals certainly will want to maintain some interaction with several contexts simultaneously. The priority call that has to get through is one example.
