In this paper we argue that temporal aspects of interactions have not yet received enough attention in interaction design research. We find this lack of concern to negatively influence both interaction design practice as well as research. This paper is therefore a first attempt to explore and examine potential techniques that might be usable to describe and(More)
Not only are people or contexts subject to change in the trajectory of artifact use, many interactive products or systems themselves also change over time. Joining the trend of longitudinal studies of user experience with cognitive, behavioral, social or historical perspectives, we propose an <i>artifact-centered temporal approach</i> for analyzing(More)
The Nabaztag rabbit is an ambient digital device with customized functions. It was advertised as an ambient display, using strong product images suggesting that it is a pet alternative. However, after early interest, the popularity of this product did not last long. In this paper, we demonstrate interaction criticism as an approach to design research,(More)
Each user of interactive systems experiences prolonged engagement with applications, products and systems. Because of limitations of contemporary long-term user research methods and imperfection in human memory, approaches for longitudinal user experience are still under-explored. In this paper, we review a recent methodological shift in user research aimed(More)
As HCI becomes more aware of long-term use experience, users' retrospection might be one starting point to explore prior interactive use. However, due to the limitation of current methodologies and human memory, research participants might recall specific prior use episodes and less their experience over time. In this note, we examine how to encourage(More)
A stairway falling detection prototype is designed to warn when elderly people fall on the stairs and also accumulatively and unobtrusively study elderly people's walking patterns. With this prototype, we try to demo a new design strategy, a pervasive way, to facilitate developing proper algorithms and living patterns for elderly people at home. Evaluation(More)
