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.

11. 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. - View Dependent Claims (12, 13, 14)
filtering errant data not associated with erasing functions.

13. The method of claim 12, wherein said filtering is based on using predetermined velocity values to distinguish between writing velocity and erasing velocity.
-
14. The method of claim 13, wherein said erasing velocity value is greater than said writing velocity value.

15. 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. - View Dependent Claims (16, 17, 18)
