Abstract

In this paper, we describe a technique to determine user preferences concerning in-car micro-gesture interaction. The approach is derived from the theater technique [1] and implies a collaborative adjustment of parameters with the experimenter until the subject has decided about the final settings. We evaluated three systematically selected gestures (zooming, sweeping, and circling) for controlling four exemplary comfort functions of the car (window lifter, air condition, radio volume, and seat heating). The main result of our study is the geometry of a “sweet spot” for micro-gesture recognition close to the steering wheel, which is independent from the underlying technical recognition approach. Additionally, preferred sizes, angles, and pause times for the investigated gestures are provided. We give indications on which of the gestures is preferred by the users (the sweeping gesture). Finally, we provide a more detailed view on the interaction between gesture preferences and function.
