Driver interface/HMI standards to minimize driver distraction/overload
This paper describes (1) the telematics distraction/overload problem, (2) what distraction and overload are and how they differ, (3) the standards and guidelines that apply to the design and evaluation of driver interfaces/human-machine interfaces (HMI) for telematics (and their strengths and...
Legibility index for examining common viewing situations a new definition using solid angle.
The legibility levels of text and graphics can be assessed using the Legibility Index, conventionally defined as the distance at which material can be read with perfect accuracy (the legibility distance) divided by the character height. The ratio equals the inverse tangent of the visual angle...
Glance strategies for using an in-vehicle touch-screen monitor
In this study, subjects in a driving simulator followed a lead vehicle that continuously changed speed while they also performed a secondary task on a touch-screen monitor that could be located at various positions within the simulator. Subjects were instructed to give priority to the following...
Validation of the static load test for event detection during hands-free conversation
To see if visual event reaction times (RTs) during handsfree conversation conditions in the Enhanced Static Load Test (ESLT) can predict RTs in similar conditions in on-road driving. Methods. Brake reaction times to random center and side light events were measured while watching a driving video,...
