Adventures in Hologram Space: Exploring the Design Space of Eye-to-eye Volumetric Telepresence

Modern volumetric projection-based telepresence approaches are capable of providing realistic full-size virtual representations of remote people.

Abstract

Modern volumetric projection-based telepresence approaches are capable of providing realistic full-size virtual representations of remote people. Interacting with full-size people may not be desirable due to the spatial constraints of the physical environment, application context, or display technology. However, miniaturizing remote people can create eye-gaze matching problems. Eye contact is essential to communication as it allows for people to use natural nonverbal cues and improves the sense of 'being there'. In this paper, we discuss the design space for interacting with volumetric representations of people and present an approach to dynamically manipulate scale, orientation, and position of holograms that guarantees eye contact. Results garnered from a 14 participant test of our augmented reality prototype show improved collaboration and mutual participant awareness.
