An Investigation of Smart Glasses for Motorcyclists as a Head-Up-Display Device - Performed on a Riding Simulator

The use of a head-up-display has been extensively researched in the context of two track vehicles, human system interaction and improved road safety. The aim of this study is to measure workload and response time for a secondary task while riding a powered-two-wheeler. For this purpose, a head mounted smart glasses device was used to provide driving information. A secondary task was implemented for comparison with a conventional digital information display in the motorcycle segment. The focus was to determine the “response time”, “response rate”, “mental workload”, “obtrusiveness” and “usefulness” for both displays. During the 15-min ride, the secondary task consisted of confirming the perception of a direction change in the navigation arrows. The mental workload was measured using the rider-activity-load-index questionnaire and compared between both displays. The results show a lower workload using the head-up-display and a faster response time and frequency fulfilling the secondary task. Usefulness depends on the shown information, which should be further investigated.
