Sensor-Based Context-Awareness for Situated Computing
Hans W. Gellersen, Michael Beigl, Albrecht Schmidt · Lancaster EPrints (Lancaster University) · 2000
It can be argued that pervasive access to information and services becomes more valuable when they are related and adapted to the real world situations of their use. We discuss sensor-based approaches to awareness of such situations based on experience from two projects, one investigating context-awareness as add-on technology for mobile devices, and the other exploring the use of everyday things as context suppliers. INTRODUCTION Global and mobile networks make information and computer-based services available almost everywhere irrespective of location, embedded technologies let global information infrastructures stretch far into our everyday environments, and advances in information interfaces extend accessibility. Beyond the ultimate availability and accessibility an entirely new quality is added when information and services get related and adapted to the real world situations in which they are used. Situations of use have inherent locality, but there are many other aspects of si...
