XTag : designing an experience capturing and sharing tool for persons with aphasia

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.
