POV Display and Interaction Methods extending Smartphone.

Persistence of Vision (POV) display uses a technique that presents an after-image that occurs when rhythmic blinking LEDs are moved swiftly. It is a cost-effective and simple method used to turn a large surface into a display. In addition, a characteristic visual expression, such as one floating in the air, can be produced. This technique is widely used because of its advantages, however, it has the limitation of poor interactivity. In this study, a system in which a smartphone can be used as a POV display by mounting a rotation mechanism and installing original applications is suggested. Furthermore, examples of the application and the possibility of interaction methods using this system are presented, including the concept, implementation, experimental results, and implications.
