Do Hand-Held Devices have a future in Augmented Reality real-life remote tasks? Refections on impact/acceptance versus Head-Mounted Displays
European Society for Socially Embedded Technologies (EUSSET)
Augmented Reality (AR) is a powerful tool for supporting remote scenarios. Despite the broad adoption of Hand-Held Devices (HHDs), one common assumption is that Head-Mounted Displays (HMDs) may revolutionize such activities, since collaborators can visualize situated instructions given by remote experts, while in a ’hands-free’ setting. This claim is typically based on toy problem user studies with rather low complexity (Lego Blocks/Tangram puzzles), but what works best for real-life scenarios is not clear. This shows a need for understanding the use/adoption of such devices in real scenarios. In this work, motivated by a partnership with the Industry sector, we discuss how HMDs and HHDs are viewed by different audiences (user study participants, domain experts and target users) for supporting on-site workers during remote maintenance tasks. After all, most stakeholders defend HHDs are still the way to go to address real-life scenarios.
