Abstract
In a pen-based computing system, a pair of microphones captures audio concurrently with a smart pen device capturing handwriting gestures. The audio captured by the pair of microphones is processed to produce an enhanced audio recording. Noise cancellation techniques may be applied to reduce noise generated by the smart pen device interacting with the writing surface to produce a higher quality audio recording. In addition, beam steering techniques may be applied to adjust the gain of portions of the audio signal from different directions and allow the user to focus between multiple audio sources.
Claims26
A method for recording audio in a smart pen computing system, the method comprising:
- capturing audio using a first microphone and a second microphone, the first and second microphones located at different positions in the smart pen computing system;
- capturing handwriting gestures by a smart pen device of the smart pen computing system concurrently with capturing the audio;
- processing the audio captured by the first and second microphones;
- and
- synchronizing the processed audio with the handwriting gestures captured concurrently with the audio.
A computer program product for recording audio in a smart pen computing system, the computer program product comprising a computer-readable storage medium containing computer program code that comprises:
- an audio capture module for capturing audio using a first microphone and a second microphone, the first and second microphones located at different positions in the smart pen computing system;
- a gesture capture module for capturing handwriting gestures, the handwriting gestures captured concurrently with capturing the audio;
- an audio processing module for processing the audio captured by the first and second microphones;
- and
- a synchronization module for synchronizing the processed audio with the handwriting gestures captured concurrently with the audio.
A pen-based computing system for recording audio, the system comprising:
- a gesture capture system on a smart pen device for capturing handwriting gestures of a user interacting with a writing surface;
- a first microphone placed at a first position and communicatively coupled to the smart pen device for recording audio concurrently with capturing the handwriting gestures;
- a second microphone placed at a second position and communicatively coupled to the smart pen device for recording the audio concurrently with capturing the handwriting gestures;
- a processor programmed to process the audio captured by the first and second microphones and to synchronize the processed audio with the handwriting gestures captured concurrently with the audio;
- a memory for storing the processed audio and the handwriting gestures;
- and
- an interface for transferring the processed audio and the captured handwriting gestures to an external computing system.
