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. },
