Head Pose Estimation

A computer vision technique that determines the orientation or direction a person's head is facing, typically classifying whether someone is looking towards or away from the camera. In accessibility contexts, head pose estimation can help blind users determine whether a passerby is looking at them — a critical social cue for deciding whether to initiate an interaction. The technique uses face detection models and additional classification layers to estimate head orientation from camera images, though accuracy can be limited by factors such as distance, lighting, and partial face visibility.
