Abstract

© 2016 ACM. In this paper, we first give an overview of the predictive display concept, which aims to minimise the demand associated with interacting with in-vehicle displays, such as touch-screens, via free hand pointing gestures. It determines the item the user intends to select, early in the pointing gesture, and accordingly simplifies-expedites the target acquisition. A study to evaluate the impact of using a predictive touchscreen in a car is then presented. The mid-air selection pointing facilitation scheme is applied, such that the user does not have to physically touch the interactive surface. Instead, the predictive display auto-selects the predicted interface icon on behalf of the user, once the required level of inference certainty is achieved. The study results, which are based on data collected from 20 participants under various driving-road conditions, demonstrate that a predictive display can significantly reduce the workload, effort and durations of completing onscreen selection tasks in vehicles.
