Claims
- 1. A retrofittable apparatus for converting a substantially planar surface into a writing surface for an electronic data capture device, the apparatus comprising:a unitary sensor array that securely and rigidly fixes a relation between a plurality of sensors and that provides a tracking function to determine the position of a marking implement on the writing surface; and a means for removably coupling the unitary sensor array to the substantially planar surface.
- 2. The apparatus of claim 1, wherein said substantially planar surface is any of a whiteboard, a blackboard, a table, a video display, a wall, a bulletin board, and a floor.
- 3. A retrofittable apparatus for converting a substantially planar surface into a writing surface for an electronic data capture device, the apparatus comprising:a unitary sensor array that provides a tracking function to determine the position of a marking implement on the writing surface, an active area on the planar surface; and a means for removably coupling the unitary sensor array to the substantially planar surface.
- 4. The apparatus of claim 3, wherein the active area comprises any of a toolbar, video window, and other feature.
