Pervasive computing environments consist of many independent collaborating electronic devices, including sensors and actuators. Ad-Hoc extendibility of such systems is desirable but the current network technologies use the concept of a central coordinator device in the network or define application profiles which are not easy to extend and maintain. The distributed architecture proposed in this paper allows these devices to organize themselves automatically to execute some pervasive system application without the intervention of a central controlling device. The knowledge that defines interactions between these devices is derived from an ontological model of a particular domain. This knowledge is distributed over the devices such that every device only has information about its own interactions and operations. A simple demonstration of this architecture is presented. © 2010 EDAA.

In this paper we describe the design and exploratory field evaluation of an experience tagging and sharing application for people with expressive aphasia. We conducted a probe study with representatives from this target user group to gain a deeper understanding of the potential use of technology to capture and share everyday experiences. We used the obtained insights in the design of a new experience tagging tool (XTag). Our field study with the resulting prototype suggests that multimedia (picture, audio and GPS) indeed offer great potential for assisting aphasics while retelling their past experiences. Specifically, the tagging application improved support over a digital camera as it could be more easily operated single-handedly, which was much appreciated by aphasics. We also share some methodological lessons that we learned from our study. © 2010 ACM.
