This report proposes a method (for SAE Recommended Practice J2365) to estimate in-vehicle task times and reviews the related human factors literature. This method will be used to evaluate alternative driver interface designs and to check compliance with the 15-second task time limit specified in SAE Recommended Practice J2364 (Navigation Function Access While Driving). Application of this method will enhance the safety and usability of driver information systems. A review of the human factors literature (Kurokawa's dissertation, Levison's Integrated Driver Model, the NASA MIDAS software, the Integrated Performance Modeling Environment, etc.) revealed that there was no personal computer software available or hand calculation methods tailored for this purpose. Therefore, the approach taken was to extend the Keystroke-Level Model (popular in human-computer interaction) using data from automotive navigation studies for calibration. |
