Sažetak
In this paper we present the results of a user study focused on evaluating the overall usability of a wearable video- communication system aimed at facilitating hands-free communication between a field technician and a remote expert. An asymmetrical cooperative electronics-based bomb defusal game was used to examine the subject’s ability to perform a manual technical task with the aid of a head- mounted-display (compared to only verbal communication) in terms of both subjective(perceived usefulness for the given task) and objective (time to complete task, number of errors) metrics. We analyze different dimensions of usability (overall system usefulness, information quality, interface quality, and device comfort) as we discuss the impact of human factors (i.e., gender, wearing Rx eye-glasses) on user experience. While system use has been shown to improve both subjective and objective metrics in some cases, results appear to be highly dependant on the task itself. Furthermore, our findings highlight the importance of exploring different ways in which ergonomic issues present in commercial smart glasses may decrease perceived usability in certain demographics.
