1 Scope
This Technical Specification 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 Technical Specification does not define calibration procedures for other evaluation activities that a laboratory might undertake.
This Technical Specification provides advice on the selection of an appropriate candidate calibration task , given an attentional demand evaluation procedure that uses primary driving-like task settings and procedures which are defined outside of this Technical Specification.
The description of a calibration task includes its application, experimental set-up, data collection, and procedures for analysis of results.
The purpose of this Technical Specification 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 Technical Specification does not provide such a criterion for a given level of attentional demand .
