8. A computer-readable storage medium on an electronic pen, wherein the computer-readable storage medium has computer-executable instructions for causing the output of pen interface information in response to a detection of a semantic ink object, the instructions comprising: detecting, on the electronic pen, one of: audio information external to the electronic pen, wherein the audio information is detected by a microphone of the electronic pen and recorded to a memory of the electronic pen, or a semantic ink object, wherein the semantic ink object is detected by a semantic input interface on the electronic pen; when audio information is detected by the microphone of the electronic pen, associating the stored audio information with an electronic document presently being modified by the electronic pen, storing the audio information with the electronic document, and displaying an icon in the presently modified electronic document adjacent to the portion of the document presently being modified, wherein the icon indicates a presence of the audio information; and when the semantic ink object is detected by the semantic input interface on the electronic pen, matching the semantic ink object to preexisting output interface information and outputting the preexisting output interface information on a sensory output interface of the electronic pen.
