An Auto-Multiscopic Projector Array for Interactive Digital Humans

Presented at the recent SiggraphAutomultiscopic 3D displays allow a large number of viewers to experience 3D content simultaneously without the special glasses or head gear. The display uses a dense array of 216 video projectors to generate images with high angular density over a wide field of view. As users move around the display, their eyes smoothly transition from one view to the next.

The installation presents "time-offset" interactions with recorded 3D human subjects. A large set of video statements was recorded for each subject, and users access these statements through natural conversation that mimics face-to-face interaction. Conversational reactions to user questions are retrieved through speech recognition and a statistical classifier that finds the best video response for a given question. Recordings of answers, listening, and idle behaviors are linked together to create a persistent visual image of the person throughout the interaction. This type of time-offset interaction can support a wide range of applications, from creating entertaining performances to recording historical figures for education.
