In the Right Place at the Right Time? A View at Latency and Its Implications for Automotive Augmented Reality Head-Up Displays
In the presented study, latency between physical event and displayed content is considered in order to provide a quantifiable criterion. In a driving simulator the influence of a contact-analog lane marker which was subjected to different stages of latency (17 ms, 50 ms, 100 ms) is examined. In total 43 participants took part in this experiment. A detection response task was conducted to evaluate the subjects’ reaction times and cognitive workload . Usability was assessed by applying the system usability scale . Changes in latency have a significant influence on stress and usability. Specifically latencies over 50 ms have a negative effect on the dependent variables. Results suggest that latencies of up to 50 ms are still considered acceptable in terms of usability as evaluated in the implemented use case.
