Evaluation of a Haptic Interface for In-Vehicle Systems

• By introducing information and communication systems higher demands are put on the human-machine-interface in the vehicle. Concurrently the load on the driver isincreasing especially concerning visual tasks, a sensory channel that from a safety perspective should be used primarily for the demanding on-road situation. Hapticinterfaces present innovative and complementary ways for the driver to communicate with the systems in the vehicle. The objective of this study was to evaluate a hapticinterface, consisting of a haptic device and a graphic display, for in-vehicle-systems. By means of a driving simulator a usability evaluation with thirteen subjects was carried out for a haptic interface and a traditional interface. In sum, it cannot be concluded that neither a haptic interface nor a traditional interface for driver in-vehicle systems is preferable as a rule. Though, it looks as if the former should be considered when the tasks become more complex while the latter is more suitable and faster in relation to simpler tasks. Furthermore, the traditional interface appears to be advantageous from a safety point of view, based on the diversion of gaze from the road. Yet, this result is not conclusive since the haptic interface is regarded as imposing less task-load, being easier to use and understand, and mainly the first choice between the two interfaces. It might be that the haptic interface is experienced as more consistent.
