Various embodiments of a modular position sensing system and method for using the system are described. The system may be used to detect the position of one or more radiation blocking objects in a sensing region. The sensing region may overlie a surface such as a wall, whiteboard, display screen or a modular display screen. When used with a modular display screen, the system may include system modules dimensions to correspond to display modules used to form the modular display screen. |
