► We perform eye-tracking from a head-mounted device designed for children. ► We use Support Vector Regression to map eye-image pixels to gaze coordinates. ► Passive lighting allows tracking on very wide field of view (96° × 96°). ► Tracking accuracy is higher for adults (1.59°) than for children (2...
