abstract = {In a controlled human-subject study we investigated the effects of mismatched physical and visual perception on cognitive load and performance in an Augmented Reality (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. Results indicated higher performance, lower cognitive load, and increased usability when participants touched a matching physical head-shaped surface and with visuals provided by a projector from underneath.},

abstract = {In this paper we report on an investigation of the effects of a self-avatar's visual similarity to a user's actual appearance, on their perceptions of the avatar in an immersive virtual reality (IVR) experience. We conducted a user study to examine the participant's sense of body ownership, presence and visual realism under three levels of avatar-owner visual similarity: (L1) an avatar reconstructed from real imagery of the participant's appearance, (L2) a cartoon-like virtual avatar created by a 3D artist for each participant, where the avatar shoes and clothing mimic that of the participant, but using a low-fidelity model, and (L3) a cartoon-like virtual avatar with a pre-defined appearance for the shoes and clothing. Surprisingly, the results indicate that the participants generally exhibited the highest sense of body ownership and presence when inhabiting the cartoon-like virtual avatar mimicking the outfit of the participant (L2), despite the relatively low participant similarity. We present our experiment and main findings, also, discuss the potential impact of a self-avatar's visual differences on human perceptions in IVR.},

simulators has different limitation that could be mitigated with various degrees of fidelity to represent medical cues. As we are exploring different ways to simulate a human patient and their effects on

learning, we would like to compare the dynamic visuals between spatial augmented reality and a optical see-through augmented reality where a patient is rendered using the HoloLens and how that

affects depth perception, task completion, and social presence.},
