A Framework for Selecting and Assessing Wearable Sensors Deployed in Safety Critical Scenarios

Robert Houghton et al. Sensors (Basel). .

Abstract

Wearable sensors for psychophysiological monitoring are becoming increasingly mainstream in safety critical contexts. They offer a novel solution to capturing sub-optimal states and can help identify when workers in safety critical environments are suffering from states such as fatigue and stress. However, sensors can differ widely in their application, design, usability, and measurement and there is a lack of guidance on what should be prioritized or considered when selecting a sensor. The paper aims to highlight which concepts are important when creating or selecting a device regarding the optimization of both measurement and usability. Additionally, the paper discusses how design choices can enhance both the usability and measurement capabilities of wearable sensors. The hopes are that this paper will provide researchers and practitioners in human factors and related fields with a framework to help guide them in building and selecting wearable sensors that are well suited for deployment in safety critical contexts.

Keywords: design; psychophysiology; safety critical; usability; wearable sensors.

Comprehensive framework of principles which should be used to develop and guide evaluation of wearable devices which monitor human psychophysiology. Design is centered, as it represents the core tenet which maximizes both the “pillars of measurement, and usability”. The arrows indicate that sensors may be iterated through some or all of these parameters before a final version is deemed suitable for its context. Usability and measurement may interact with one another through iteration, with different priorities being focused upon, dependent on user needs and user feedback.
