2. Context
• There are approximately 150 definitions of
context coming mainly from the web in
different domains of disciplines. Researchers

different domains of disciplines. Researchers
are not unanimous in what context is. They
emphasized that context is an ill- defined
concept (Bazire and Brézillon, 2005).

8. Context-Aware Application?
“Context-Aware Computing (CAC)is a mobile computing
paradigm in which applications can discover and take advantage
of contextual information (such as user location, time of day,
nearby people and devices, and user activity)”(Chen, G., & Kotz,
D. , 2000)
8
D. , 2000)
Applications that use context to make a better understanding of
users, called Context-Aware Applications (Dey,2001).
CAC is an interdisciplinary research area in the field of HCI
(Panniello et al, 2009).
