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 its multimedia presentation according to the user's activity as well as location.
