designing for a proximity and orientation-aware environment
In the everyday world, much of what we do is dictated by how we interpret spatial relationships. This is called proxemics. What is surprising is how little spatial relationships are used in interaction design, i.e., in terms of mediating people’s interactions with surrounding digital devices such as digital surfaces, mobile phones, and computers. Our interest is in proxemic interaction, which imagines a world of devices that has fine-grained knowledge of nearby people and other devices – how they move into range, their precise distance, and even their orientation – and how such knowledge can be exploited to design interaction techniques. In particular, we show how we used proxemic information to regulate implicit and explicit interaction techniques. We also show how proxemic interactions can be triggered by continuous movement, or by movement in and out of discrete proxemic regions. We illustrate these concepts with the design of an interactive vertical display surface that recognizes the proximity of surrounding people, digital devices, and non-digital artefacts – all in relation to the surface but also the surrounding environment. Our example application is an interactive media player that implicitly reacts to the approach and orientation of people and their personal devices, and that tailors explicit interaction methods to fit.
