Background

The steady trend towards the integration of new comfort and entertainment functions in the automobile leads to an increase in control elements for the driver. In order to position as many functions as possible within the optimum reach of the driver, the focus is increasingly placed on complex operating concepts using turn-push dials or touch displays that guide the driver through various menu levels. However, this increases the mental strain, the necessary hand-eye coordination, the visual distraction and the duration of the operation. Here, the non-contact gesture control as an innovative operating concept offers the possibility of making human-machine interaction more efficient while driving.

Aims

This project examines which gestures can in principle be used with regard to distinctiveness, intuitive comprehensibility, efficient operation and distraction.

Method

After hand gestures had been defined and categorised, a comprehensive catalogue of gestures was compiled. This catalogue contains a total of 45 static and dynamic gestures that can, in principle, be performed while driving. In a first test series in the driving simulator, the influence of a gesture-based operation on distraction was analysed in comparison to a conventional haptic operation. Subsequently a series of laboratory tests was carried out to determine which gestures are intuitively chosen by drivers to operate selected functions in the vehicle. The theoretically derived gesture catalogue was then extended to 75 gestures. In a further study in the driving simulator, the influence of dynamic gestures on motor distraction was investigated.
