Understanding user engagement from sensed data

Spatial and Situational Awareness Techniques

Based on social psychology, we measure nonverbal behavior of users, such as speaking times (turns), hand gesture, head direction, gaze and interpersonal distance and so on, and establish regression model to estimate user’s group activities such as engagement and efficiency. We focus on establishing the estimation model as well as new exploring new sensing methods using ambient devices (e.g., cup-shaped ambient device).
