This SAE Recommended Practice defines key terms used in the description and analysis of video based driver eye glance behavior, as well as guidance in the analysis of that data. The information provided in this practiced is intended to provide consistency for terms, definitions, and analysis techniques. This practice is to be used in laboratory, driving simulator, and on-road evaluations of how people drive, with particular emphasis on evaluating Driver Vehicle Interfaces (DVIs; e.g., in-vehicle multimedia systems, controls and displays). In terms of how such data are reduced, this version only concerns manual video-based techniques. However, even in its current form, the practice should be useful for describing the performance of automated sensors (eye trackers) and automated reduction (computer vision).
The revised version of J2396 addresses the definitions and experimental measures related to driver visual behavior. It was prepared and adopted in 2016. This document was previously issued in 2000 and subsequent technologies have increased the pervasiveness and challenges of measuring driver visual behavior. One goal of this review and revision was to update the document with current terminology and references. In addition, terms were made consistent with other SAE documents. The updates to J2396 are intended to remain consistent with the International Organization for Standardization (ISO) 15007-1:2014 and 15007-2:2014.
