Context Awareness by Analysing Accelerometer Data

Cliff Randell, Henk Muller, Context Awareness by Analysing Accelerometer Data. The Fourth International Symposium on Wearable Computers. Blair MacIntyre, Bob Iannucci, (eds.). ISSN 1530-0811, pp. 175–176. October 2000. PDF, 16 Kbytes.


In this paper we describe continuing work being carried out as part of the Bristol Wearable Computing Initiative. We are researching processing techniques for data from accelerometers which enable the wearable computer to determine the user's activity. Techniques already employed by others have been explored and we propose new methods for analysing the data delivered by these devices. We try to minimise the number of devices needed by using a single X-Y accelerometer device. Using our techniques we have adapted our GPS based Tourist Guide application to vary it's multimedia presentation according to the user's activity as well as location.
