Continuum of virtual-human space: towards improved interaction strategies for physical-virtual avatars

In this work, a broad continuum of 3D space that encapsulates avatars, ranging from artificial to real in shape, appearance and intelligence is defined. The research focuses on the control of physical-virtual avatars that occupy a specific region in this space that may be suitable for interacting with elements in the environment. To facilitate this control, a paradigm called microposes is developed that overcomes the need for high network bandwidth during remote tele-operation of avatars. The avatar itself uses a control strategy that interprets the received microposes data and executes motions that appear natural and human-like in the presence of data loss and noise. The physical-virtual avatar is used in several training and learning scenarios. Results during testing reveal a reduced bandwidth requirement during remote tele-operation of physical virtual avatars and a good motion tracking performance with respect to a commanded pose from the inhabiter.
