System and method for capturing editable handwriting on a display

摘要

Systems, methods, and apparatus for a touch sensitive display device providing editable handwriting capture are described. A display device with a detachable front panel is capable of interactive touch sensing and editable handwriting capture. An ultraviolet or near ultraviolet light source and camera can be configured to capture images of textual input made on the detachable front panel of the device with a pen having water soluble fluorescent ink that is transparent or nontransparent such that the notes are visible under ultraviolet or near ultraviolet light and transparent when little or no ultraviolet or near ultraviolet light is present. The detachable front panel may be removed from the display device for cleaning and ease of use.
