1. An electronic pen, comprising: a semantic input interface on the electronic pen; a sensory output interface on the electronic pen; a microphone on the electronic pen; a processor on the electronic pen; and a memory on the electronic pen, wherein the memory includes computer-executable instructions stored on the memory, wherein the computer-executable instructions are configured for: detecting one of: audio information external to the electronic pen, wherein the audio information is detected by the microphone of the electronic pen device and recorded to the memory of the electronic pen, or a semantic ink object, wherein the semantic ink object is detected by the semantic input interface on the electronic pen; when audio information is detected by the microphone of the electronic pen device, 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 that indicates 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 the sensory output interface of the electronic pen.
