Context is more than location. Schmidt, Beigl, Gellerson.
These chaps break down the concept of “context” as it relates to human using mobile computing devices, into this hierarchy:
- Human Factors
- User (knowledge of habits, emotional state, biophysiological conditions, …)
- Social Environment (co-location of others, social interaction, group dynamics, …)
- Task (spontaneous activity, engaged tasks, general goals,…)
- Physical Environment
- Location (absolute position, relative position, co-location,…)
- Infrastructure (surrounding resources for computation, communication, task performance…)
- Location (noise, light, pressure,…)
This paper also includes a number of good links to other work on context.
