Point Select: Designing an Interaction Technique for Inputting Surrounding Point of Interests in Driving Context
share
We propose an interaction technique called "Point Select." It enables a driver to directly enter a point of interest (POI) into the in-vehicle infotainment system while driving in a city. Point Select enables the driver to directly indicate with a finger, identify, adjust (if required), and finally confirm the POI on the screen by using buttons on the steering wheel. Based on a comparative evaluation of two conditions (driving-only and driving with input-task) on a simulator, we demonstrated the feasibility of the interaction in the driving context from the perspective of driver performance and interaction usability at speeds of 30, 50, and 70 km/h. Although the interaction usage and speed partially affected the driver's mental load, all the participants drove at an acceptable level in each condition. They carried out the task successfully with a success rate of 96.9 of 1.82 seconds on average.
