N2 - While research in the field of augmented reality (AR) has produced many innovative human-computer interaction techniques, some may produce physical and visual perceptions with unforeseen negative impacts on user performance. In a controlled human-subject study we investigated the effects of mismatched physical and visual perception on cognitive load and performance in an AR touching task by varying the physical fidelity (matching vs. non-matching physical shape) and visual mechanism (projector-based vs. HMD-based AR) of the representation. Participants touched visual targets on four corresponding physical-visual representations of a human head. We evaluated their performance in terms of touch accuracy, response time, and a cognitive load task requiring target size estimations during a concurrent (secondary) counting task. After each condition, participants completed questionnaires concerning mental, physical, and temporal demands; stress; frustration; and usability. Results indicated higher performance, lower cognitive load, and increased usability when participants touched a matching physical head-shaped surface and when visuals were provided by a projector from underneath.
