INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240214761 titled 'INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM
Simplified Explanation
The patent application describes a system that uses two speakers and one microphone to measure the position of the microphone. By analyzing the audio signals received from the speakers, the system can calculate the microphone's position based on the difference in arrival times of the signals.
- The system includes two speakers and one microphone.
- Audio signals from the speakers are used to calculate the microphone's position.
- The system utilizes spread spectrum modulation and cross-correlation to determine the microphone's location accurately.
Key Features and Innovation
- Utilizes audio signals from two known positions to calculate the microphone's position.
- Uses spread spectrum modulation for accurate measurements.
- Calculates the microphone's position based on arrival time differences.
Potential Applications
- Game controllers
- Head-mounted displays (HMD)
Problems Solved
- Accurately measuring the position of a microphone in a system with multiple speakers.
- Providing a method for calculating the microphone's location based on audio signals.
Benefits

Original Abstract Submitted
there is provided an information processing device, an information processing method, and a program that enable a system including two speakers and one microphone to measure a position of the microphone. an audio reception block receives an audio signal including a spreading code signal obtained by performing spread spectrum modulation on a spreading code, the audio signal being output from two audio output blocks existing at a known positions, and calculates a position of an audio reception unit on the basis of an arrival time difference distance that is a difference between distances to the two audio output blocks based on an arrival time at which a peak of cross-correlation is detected. the present invention can be applied to a game controller or an hmd.
