Touch-Screen Task-Element Times for Improving SAE Recommended Practice J2365: A First Proposal.

摘要

This report describes the identification of task elements and the estimation of their times for in-vehicle tasks such as dialing a phone number or finding a song using a touch screen. These elements were derived from an experiment in which 24 drivers distributed across three age groups completed 40 trials involving various in-vehicle tasks. These data will be used to develop a new version of Society of Automotive Engineers Recommended Practice J2365, which is used to predict task times when the driver interface is at the wireframe stage, well before hardware and software are available to collect driver-performance data. The predicted, static (non-driving) task times are used to predict which tasks are most likely to be unacceptably distracting and unsafe to do while driving.
