Abstract
We demonstrate two-dimensional navigation with velocity control on a single button. Users can vary the speed of the controlled object by rhythm tapping, and can control direction by pressing and tilting, releasing the button once the desired rotation is achieved. Feedback is multisensory. Tactile pulses are being delivered at 30-degree intervals during rotation, simulating the detents of a rotary encoder. Simultaneously, a sonic glissando accompanies rotation, raising or lowering pitch according to the change of direction. Absolute positional feedback is provided visually as well as auditorilly, with an intermittent auditory tone whose pitch conveys vertical position, panned to the left or to the right depending on horizontal position. The rhythmic pace corresponds directly to the on-screen element speed, defined by the tapping interval. Participants will be engaged in a target-following task, thus being able to appreciate the precise speed and direction control of the multisensory navigation experience.
