Point & Select: Designing an Interaction Technique for Inputting Surrounding Point of Interests in Driving Context
This addresses the challenge of safe and efficient in-vehicle infotainment input for drivers, though it is an incremental improvement over existing interaction methods.
The paper tackles the problem of enabling drivers to input points of interest (POIs) while driving by proposing the 'Point & Select' interaction technique, which achieved a 96.9% success rate and an average task completion time of 1.82 seconds in a simulator evaluation.
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% and task completion time of 1.82 seconds on average.
