Abstract Cognitive load refers to the amount of effort required by an indi- vidual to process information. Dating back more than fifty years, the cognitive psychology community has conducted experiments showing that the cognitive load experienced by an individual can be measured using sub-millimeter fluctuations in their pupil size, assessed using medical grade infrared devices […]

Real-Time Emotion Recognition

Abstract This paper discusses facial expression recognition based on the Eigen faces method and using depth data from a ToF (Time-of-flight camera) camera in order to resist varying lighting conditions in real-time applications and computer games. For each frame, the system extracts a matrix transformation for a bitmap image, and applying the same matrix to […]
