Toward context-aware computing: Experiences and lessons

View publication


Distractions occur especially in mobile environments, because walking, driving, or other real-world interactions often preoccupy the user. To minimize distractions, a pervasive-computing environment must be context aware. This paper defines an activity-attention framework for context-aware computing. In addition, the spatial and temporal aspects of applications developed are discussed and introduces a pervasive-computing architecture.
