Implementing Phicons: Combining Computer Vision with InfraRed Technology for Interactive Physical Icons
This paper describes a novel physical icon [3] or “phicon-” based system that can be programmed to issue a range of commands about what the user wishes to do with handdrawn whiteboard content. Merely placing a labeled phicon in proximity to the whiteboard content material, automatically executes the chosen command. This is achieved using infrared signaling in combination with image processing and a ceiling-mounted camera system. We leverage existing camera systems that are already used for capturing whiteboard content [4] by further augmenting these systems to detect the presence and location of IR beacons within an image. An HDLC-based protocol and a built-in IR transmitter is used to send these signals.
