abstract = {Motion correlation interfaces are those that present targets moving in different patterns, which the user can select by matching their motion. In this paper, we re-formulate the task of target selection as a probabilistic inference problem. We demonstrate that previous interaction techniques can be modelled using a Bayesian approach and that how modelling the selection task as transmission of information can help us make explicit the assumptions behind similarity measures. We propose ways of incorporating uncertainty into the decision-making process and demonstrate how the concept of entropy can illuminate the measurement of the quality of a design. We apply these techniques in a case study and suggest guidelines for future work.},

abstract = {Eye gaze is a fast and ergonomic modality for pointing but limited in precision and accuracy. In this work, we introduce BimodalGaze, a novel technique for seamless head-based refinement of a gaze cursor. The technique leverages eye-head coordination insights to separate natural from gestural head movement. This allows users to quickly shift their gaze to targets over larger fields of view with naturally combined eye-head movement, and to refine the cursor position with gestural head movement. In contrast to an existing baseline, head refinement is invoked automatically, and only if a target is not already acquired by the initial gaze shift. Study results show that users reliably achieve fine-grained target selection, but we observed a higher rate of initial selection errors affecting overall performance. An in-depth analysis of user performance provides insight into the classification of natural versus gestural head movement, for improvement of BimodalGaze and other potential applications.},

abstract = {Gaze may be a good alternative input modality for people with limited hand mobility. This accessible control based on eye tracking can be implemented into telepresence robots, which are widely used to promote remote social interaction and providing the feeling of presence. This extended abstract introduces a Ph.D. research project, which takes a two-phase approach towards investigating gaze-controlled telepresence robots. A system supporting gaze-controlled telepresence has been implemented. However, our current findings indicate that there were still serious challenges with regard to gaze-based driving. Potential improvements are discussed, and plans for future study are also presented.},

abstract = {We present an interface for control of a telerobot that supports field-of-view panning, mode selections and keyboard typing by head- and gaze-interaction. The utility of the interface was tested by 19 able-bodied participants controlling a virtual telerobot from a wheelchair mounted on rollers which measure its wheel rotations, and by 14 able-bodied participants controlling the telerobot with a exercise bike. Both groups tried the interface twice: with head- and with gaze-interaction. Comparing wheelchair and bike locomotion control, the wheelchair simulator was faster and more manoeuvrable. Comparing gaze- and head-interaction, the two input methods were preferred by an equal number of participants. However, participants made more errors typing with gaze than with head. We conclude that virtual reality is a viable way of specifying and testing interfaces for telerobots and an effective probe for eliciting peoples subjective experiences.},
