Voice and position localization

A system comprising

• a) apparatus configured for processing of both audible and ultrasonic sound inputs, comprising:
• a sensor with a frequency response spanning both audible and ultrasonic frequencies;
• and
• processing electronics configured to separate the audible and ultrasonic input frequencies for independent use, and comprising a first filter configured to filter audible frequencies and a second filter configured to filter ultrasonic frequencies and a multiplexer for switching between the separated frequencies to provide a single output, the multiplexer allowing for simultaneous processing, by the processing electronics, of audible and ultrasonic output frequencies from the sensor, the processing including performing noise cancellation;
• and
• b) a pointing device configured to emit ultrasonic sound.

A system for processing of both audible and ultrasonic sound inputs, comprising:

• means for detecting the audible and ultrasonic sound inputs, the means for detecting the audible and ultrasonic sound inputs having a frequency response spanning both audible and ultrasonic frequencies;
• means for filtering the audible and ultrasonic sound inputs to separate the audible sound input and the ultrasonic sound input for independent use;
• means for multiplexing the separated audible sound input and the ultrasonic sound input to switch between the separated audible sound input and the ultrasonic sound input to provide a single output for simultaneous processing;
• and
• means for simultaneously processing the separated audible sound input and the ultrasonic sound input, the processing including performing noise cancellation.

A computer-readable medium including instructions that when executed by a processor causes the processor to perform a method comprising:

• filtering audible and ultrasonic sound inputs detected using a sensor having a frequency response spanning both audible and ultrasonic frequencies to separate the audible sound input and the ultrasonic sound input for independent use;
• multiplexing the separated audible sound input and the ultrasonic sound input to switch between the separated audible sound input and the ultrasonic sound input to provide a single output for simultaneous processing;
• and
• simultaneously processing the separated audible sound input and the ultrasonic sound input, the processing including performing noise cancellation.
