Wearable Robot Acceptance: Understanding the Impact of Trialability on User Perception

Abstract

The use of emerging technologies such as Wearable Robots (WRs) or exoskeletons has gained considerable attention in the construction industry in recent times. WRs or exoskeletons augment workers' physical capacity when performing physically demanding tasks. While there is growing interest in exoskeletons, existing literature suggests that some workers oppose WR use on job sites. This resistance is largely driven by second-hand information gathered through multiple channels, and not based on actual use. Therefore, it is important to assess how hands-on experience (trialability) influences the end-user perception of the use of exoskeletons. To fill this gap, the researcher utilized a mixed-method approach consisting of a structured literature review, controlled experiment, and surveys (pre-post experiment surveys). Statistical analyses revealed that in most cases, trialability had a positive influence on technology acceptance constructs assessed (including “Behavioral Intention to Use”), confirming the important role of hands-on experience in exoskeleton integration research and practice.
