Development of a Head Gesture Interface for a Self-portrait Camera

Most existing digital camera user interfaces place little emphasis on self- portrait options. Therefore, it is not always easy to take self-portraits using conventional user interfaces. This paper presents a vision-based head gesture interface for controlling a self-portrait camera that helps users to take self-portraits effectively and efficiently. Intu- itive nodding and head-shaking gestures control the camera zoom in/out on the face, and a mouth-opening gesture triggers the camera to take a picture. We evaluated its usability factors (effectiveness, efficiency, and satisfaction) and compared it to a remote control in a user study. The results suggest that our interface is useful for taking self-portrait pictures.
