We conduct extensive user evaluations which demonstrate the perceptual benefits of our algorithm. Our approach also allows the user to interact with the agents from a first-person perspective in immersive settings. Interactions, and results in smoother and plausible locomotive behaviors.

Simulating Movement Interactions between Avatars & Agents in Virtual Worlds using Human Motion Constraints The results suggest that reach estimations become more accurate as the visual fidelity of the avatar increases, with accuracy for high fidelity avatars approaching real-world performance as compared to low-fidelity and end-effector conditions.
Performance with a virtual avatar was also compared to real-world performance. This study tested the effect of three levels of avatar fidelity on the accuracy of distance estimations in the near-field. While research has demonstrated that self-avatars can enhance ones sense of presence and improve distance perception, the effects of self-avatar fidelity on near field distance estimations has yet to be investigated.

Investigating the Effects of Anthropomorphic Fidelity of Self-Avatars on Near Field Depth Perception in Immersive Virtual EnvironmentsĮlham Ebrahimi, Leah Hartman, Andrew Robb, Christopher Pagano, Sabarish V. Our main result shows that affinity towards virtual characters is a complex interaction between the character’s appearance and personality, and that realism is in fact a positive choice for virtual characters in virtual reality. We used a number of perceptual metrics such as subjective ratings, proximity, and attribution bias in order to test our hypothesis. We were particularly interested in whether different render styles (realistic, cartoon, etc.) would directly influence appeal, or if a character’s personality was the most important indicator of appeal. In this paper, we conducted a large-scale experiment on over one thousand members of the public in order to gather information on how virtual characters are perceived in interactive virtual reality games. In Virtual Reality, there have been few attempts to investigate this phenomenon and the implications of rendering virtual characters with high levels of realism on user enjoyment. This effect, described as the uncanny valley, is the reason why realism is often avoided when the aim is to create an appealing virtual character.
