Haptic Interface for Vehicular Touch Screens

Once the domain of purely physical controls such as knobs, levers, buttons, and sliders, the vehicle dash is rapidly transforming into a computer interface. This presents a challenge for drivers, because the physics - based cues which make traditional controls easy to operate with limited visual confirmation are absent on traditional screens. The authors investigate the addition of programmable physics–based cues to a visual display as a method to reduce eyes–off–road time. A TPaD variable friction touchpad was installed in the Ford VIRTTEX motion driving simulator. Subjects performed target acquisition and slider adjustment task s under visual, visual/haptic, and haptic feedback conditions. For the two tasks, the authors found that the visual/haptic condition resulted in 39% and 19% decreases in total eyes–off–road time per task while showing negligible differences in task performance. Subjects showed a clear preference for combined visual and haptic feedback.
