PukuPuCam: a recording system from third-person view in scuba diving

In this paper, we propose "PukuPuCam" system, an apparatus to record one's diving experience from a third-person view, allowing the user to recall the experience at a later time. "PukuPuCam" continuously captures the center of the user's view point, by attaching a floating camera to the user's body using a string. With this simple technique, it is possible to maintain the same viewpoint regardless of the diving speed or the underwater waves. Therefore, user can dive naturally without being conscious about the camera. The main aim of this system is to enhance the diving experiences by recording user's unconscious behaviour and interactions with the surrounding environment.
