Abstract: A remote controllable electronic whiteboard system and method of operating the remote controllable electronic whiteboard system are provided. An exemplary remote controllable electronic whiteboard system includes an electronic whiteboard in communication with a remote control device. Methods of operating the electronic whiteboard system including the use of a remote control device are also provided.

Abstract: An eraser for use on an electronic whiteboard with a protrusion area on the erasing surface forming a convex area on the erasing surface for establishing a positive point of contact with the whiteboard; an electronic whiteboard system including such an eraser, a controller for storing data relating to information written on and erased from the whiteboard data, and a filter for preventing the storage of digital data relating to contacts with the whiteboard not attributable to normal writing or erasing actions.

Abstract: A technique for building touch-sensitive panels which permits construction of large, low-cost electronic whiteboards with improved feel. The electronic whiteboards are of the resistive membrane type, in which a touch on a flexible membrane causes the membrane to come into contact with a surface and that in turn changes the resistances across the membrane and the surface, permitting determination of the location of the touch. A gap between the flexible membrane and the surface is maintained primarily by the use of relatively large spacing structures located between the membrane and the surface, instead of by tension on the membrane. The use of large spacing structures permits the surface to be made using relatively irregular and therefore low-cost material. The spacing structures are backed by an elastic layer, which permits the spacing structures to yield to a touch on the screen.
