Designing Physical Interaction with Sensor Drawbacks in Mind

Physical interaction often relies on information stemming from sensors perceiving the real world. Sensors however, have imperfections resulting in drawbacks such as uncertainty and latency. Consequently, the improvement of sensors and perception methods is important. In this paper we argue however that imperfections of sensing will remain and that the key to better physical interaction lies in taking into account those sensor drawbacks explicitly during the design of the interaction. In order to take a first step in this direction we analyze sensor drawbacks and their effects on physical interaction. Based on this discussion we propose example solutions to the arising problems.
