Practical issues in the application of occlusion to measure visual demands imposed on drivers by in-vehicle tasks.

摘要: Occlusion is a practical technique to measure the visual demand imposed by in-vehicle tasks and assess whether task can be resumed having been interrupted. This study describes number of important factors variables that need controlled ensure reliability results. Training participants on found help consistency five training sessions are required for complex tasks. No significant differences in with without occlusion goggles reported. The sample size dependent variability task; those investigated an appropriate 14. For systems exhibit delay response user, improved when these delays excluded from timing measurements. In terms calculating parameter R, within-participant basis most consistent taking ratio respective median total shutter open time times across trial repetitions completed one participant each under evaluation and, purposes identifying interface designs poor resumability, 85th percentile value identified as suitable. Findings discussed future application information (IVIS).
