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.
Claims18
An eraser for use on a flexible membrane electronic whiteboard, said eraser comprising:
- an eraser body portion having a flat surface;
- at least one member protruding from said flat surface;
- and
- an erasing surface on said flat surface covering said protruding member.
A method for simultaneously erasing physical and electronic indicia on a flexible membrane electronic whiteboard, said method comprising the steps of:
- (a) contacting a first area of a flexible membrane electronic whiteboard to be erased with an eraser, wherein said eraser body portion has a flat surface, at least one member protruding from said flat surface, and an erasing surface on said flat surface covering said protruding member;
- (b) communicating a positive eraser position upon contact of said eraser with a first area of said electronic whiteboard;
- (c) maintaining pressure on said eraser in contact with said electronic whiteboard while moving said eraser to a second area of said electronic whiteboard, and
- (d) simultaneously erasing physical and electronic indicia from said electronic whiteboard.
An electronic whiteboard erasing system for an electronic whiteboard system having a digitizer with a flexible membrane writing surface capable of sensing changes in applied pressure comprising:
- (a) a computer adapted to be communicatively connected to said digitizer;
- said computer capable processing changes in applied pressure on the flexible membrane to delimit an area to be erased and capable of erasing electronic data associated with said delimited area;
- and
- (b) an eraser for simultaneously erasing physical and electronic indicia, wherein said physical and electronic indicia are identified when said eraser contacts said writing surface, said eraser body portion has a flat surface, at least one member protruding from said flat surface, and an erasing surface on said flat surface covering said protruding member.
