A team of researchers from Disney Research, the California Institute of Technology, the University of Illinois at Urbana-Champaign, and Walt Disney Imagineering is imbuing animatronic robots with lifelike eye gaze.
The system they are using decides where to gaze by first identifying a person to target using an RGB-D camera; if multiple people are visible, the system calculates a curiosity score for each, based on the amount of motion, and chooses the highest-scoring target.
The robot then will display high-level gaze behavior (reading, glancing, engaging, or acknowledging) determined by score.
An underlying subsumption architecture dictates lower-level motion behaviors like breathing, small head movements, eye blinking, and saccades.
