abstract

The computational and contextual edifice around which we will build our ubicomp user interfaces are complex and constantly changing. This context include physiological, environmental and computational state. In this regard, can we model the physiological differences between people and use the models to adapt and personalize designs, user interfaces and artefacts? Can we model, measure and predict the cost of users altering their gaze in single or multi-display environments? If so, can we personalize interfaces using this knowledge. What about when moving and while the distance between user and screen is varying. Can this be considered a new modality and used to personalize the interfaces along with physiological differences and our current gaze. In this talk we seek to answer some of these questions. We define Ubicomp User Interfaces and introduce an Individual Observer Model of human eyesight, which we use to simulate 3600 biologically valid human eyes. We also report on controlled lab and outdoor experiments with real users. This is to measure both gaze and distance from the screen in an attempt to quantify the cost of attention switching along with the use of distance as a modality. In each case, for distance, gaze or expected eyesight we would like to develop models which can allow us to make predictions about how easy or hard it is to see visual information and visual designs, along with altering the designs to suit individual users based on their current context.
