| Abstract The impact of wearing personal protective equipment (PPE) on the usability of a set of interaction devices was examined using a single experiment. Participants performed two concurrent tasks: tracking and monitoring/response, while wearing or not wearing PPE, and the resulting performance impact was measured. A differential impact of gloves on device usability according to the glove characteristics was shown. Heavy gloves impaired performance on both response times and the tracking task. Light gloves did not impede task performance. Some headwear was found to hinder colour change detection. Tentative conclusions regarding effects of device orientation and error rates were also made. The results were used to create an update to the extant UK defence standard. Areas proposed for further research include the impact of performance shaping factors on PPE and usability of interaction devices; study of usability impact with different task types; and specific design investigations regarding interaction device design for use with PPE. |
