Alcance
This document provides procedures that can be used as a secondary task in a dual task setting to determine whether that evaluation setting is standardized and valid for purposes of assessing driver attentional demand due to the use of an in-vehicle system. This document does not define calibration procedures for other evaluation activities that a laboratory might undertake.This document provides guidance on selecting a calibration task given a specific primary task. The primary tasks of interest include those that would be used in the evaluation of attentional demand. Such primary tasks are defined in other documents.The description of a calibration task includes its application, experimental setup, data collection, and procedures for analysis of results.The purpose of this document is not to define a reference criterion as to whether a given secondary task is suitable for use while driving. Although specific settings of parameters of a calibration task might be used to realize such a predefined pass/fail criterion, this document does not provide such a criterion for a given level of attentional demand.
