Location-based services, digital geocaches, and proximity interactions are previously described in context awareness research. Previous research explored the interaction between people and environmental changes.
I made a presentation to survey previous work in context awareness. This presentation considers four dimensions to analyze the use of the location variable within context-aware systems:
The presentation concludes with the limitations of location-based information.
