A digital pen adapter 602 that can be attached to a digital pen 600 allows the functionality of the digital pen to be expanded. The digital pen has a writing tip and the adapter has a writing tip 604 (e.g. similar to a marker pen writing tip) that is exposed for contact with a writing surface (e.g. a flip chart) in place of the writing tip of the digital pen. The digital pen provides an imaging system adapted to image a portion of the writing surface located at or at a predetermined position from the tip of the digital pen writing tip when the digital pen writing tip is in contact with the writing surface. |
