Keyboard for an electronic writeboard and method
CA 2252302 A1
Abstract
An electronic writeboard for communicating with a computer including applications software and running an active application comprises a touch sensitive panel on which the screen image output of the computer is displayed. The touch sensitive panel is responsive to user contact and generates events. A keyboard window is displayed on the touch sensitive panel and includes a keyboard having a plurality of user selectable keys. A driver receives the events and senses user contact on the touch sensitive panel within the keyboard window and generates messages in response thereto. A controller executing a keyboard application receives the messages. The keyboard application processes the messages to provide data to the active application running on the computer corresponding to keys of the keyboard contacted by the user.
