Awareness of the future and some thoughts about classification
It finally occurred to me that the area of location-based application is now well differentiated by the time spectrum it covers. What I called mutual location awareness in my dissertation (knowing where other people are located) can relate to the past, the present and the future. Theories in Computer Supported Collaborative Work describes this in term of synchrony: participants may either be aware synchronously (knowledge about events that happen currently) or asynchronously (knowledge about events in the past). The problem here is that some asynchronous systems are both conveying elements about the past and the present; in addition, this variable does not account for knowledge about future events. Therefore, instead of using the synchrony metaphor, let's use "time span".
Why do I blog this? sorting out ideas for a paper about mutual location-awareness.
