Intermodal differences in distraction effects while controlling automotive user interfaces

In this study, the haptical and gestural user input modes are compared with regard to distraction from a controlling task similar to steering a car. The examination is carried out in a driving-simulation laboratory. While performing the controlling task permanently, the test subject has to execute a variety of user input with a given modality. Haptical input is done by using buttons or a rotary knob while gestural input consists of dynamic right hand movements in a designated space. During the experiment, the controlling error, the object recognition performance, and the required duration for each user input are measured. The results show a significant benefit for gestural input.     «
