Binaural Recording For Smart Pen Computing Systems
First Claim
1. A pen-based computing system for recording and playing back audio comprising:
- a left audio device adapted to fit proximate to a user'"'"'s left ear, the left audio device having an integrated left microphone for recording a left audio channel, and an integrated left speaker for playing back the recorded left audio channel;
a right audio device adapted to fit proximate to a user'"'"'s right ear, the right audio device having an integrated right microphone for recording a right audio channel and an integrated right speaker for playing back the recorded right audio channel;
a smart pen device configured to capture handwriting gestures and configured to record left and right audio channels from the left and right audio devices, the smart pen further configured to synchronize the captured handwriting gestures in time with the left and right audio channels; and
an interface for transmitting the left and right audio channels recorded by the left and right microphones to the smart pen device and for transmitting the recorded left and right audio channels from the smart pen device to the left and right speakers for playback.

Abstract
A pen based computing system concurrently captures handwriting gestures and records audio using binaural recording. A binaural headset communicatively coupled to the smart pen device uses at least two microphones. A left microphone is placed in or near the left ear and the right microphone is placed in or near the right ear, each facing outward. Speakers are integrated into a shared housing with the microphones facing inward towards the ear canal to play back the audio recordings. By recording audio with microphones placed close to the ears, the system provides realistic sounding playback and allows users to more easily differentiate between multiple sources of audio.

13. A headset for recording and playing back audio, comprising:
-
a left earbud adapted to fit substantially within a left ear, the left earbud comprising an integrated left microphone for recording a left audio channel and an integrated left speaker for playing back the recorded left audio channel, the left microphone facing opposite the left speaker; a right earbud adapted to fit substantially within a right ear, the right earbud comprising an integrated right microphone for recording a right audio channel and an integrated right speaker for playing back the recorded right audio channel, the right microphone facing opposite the right speaker; and an interface for transmitting the left and right audio channels captured by the left and right microphones to a memory and for transmitting recorded left and right audio channels from the memory to the left and right speakers for playback. - View Dependent Claims (14, 15, 16)

17. A method for recording and playing audio in a smart pen computing system, comprising:
-
recording left and right audio channels using a left microphone located proximate to a left ear and a right microphone located proximate to a right ear; capturing handwriting gestures concurrently with the recording the left and right audio channels using a smart pen device; synchronizing the left and right audio channels with the captured handwriting gestures; and playing back the left and right audio channels through left and right speakers, wherein the left speaker shares a first housing with the left microphone and the right speaker shares a second housing with the right microphone. - View Dependent Claims (18, 19, 20, 21)
