Standard Test Method for Measuring Exoskeleton Cognitive Fit, Perceived Safety, and Acceptance
1.1 This test method covers a procedure for assessing the user’s intent to accept working with an exoskeleton, their perceived safety while using the exoskeleton, as well as the cognitive fit of the exoskeleton. This test method, the Cognitive Fit, Perceived Safety, and Acceptance (CSA) during exoskeleton use assessment tool, is a subjective questionnaire designed to discover the cognitive fit, acceptance, and perceived safety of a particular exoskeleton design for a user given a particular task.
1.1.1 It is vital that this test method be conducted by personnel having the knowledge and experience appropriate to perform human factor and usability assessments. Fundamental notions of human factors and ergonomics can be found in Salvendy, G., 2012,2 or Wilson, J.R. and Corlett, N., 2005.3 Fundamental notions of usability can be found in ISO 9241-11:2018.
1.1.2 This test method consists of two questionnaires: a ranked choice safety perception questionnaire and a Likert scale questionnaire (see Fig. 1). These two questionnaires are given to a worker twice, once after the work activity is performed without the exoskeleton and once after the work activity is conducted with the exoskeleton. An example of these questionnaires is in Appendix X1.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
