C11644: New 3D Sound Head Tracking SystemNovelty:
A headphone based head-tracking system that improves location of sound as the head rotates.
Value Proposition:
Current head tracking equipment uses expensive electromagnetic based approaches. Commercial gaming headsets are also available, but use infrared tracking so they are only line-of-sight. They usually do not support full head rotation over all angles and they require an infrared sensor to be attached to a TV. The head-tracking systems benefits are:
• Sensors cost only a few dollars each(similar to the sensors used in modern smart phones).
• This method is widely applicable to gaming, entertainment, and virtual training/simulation.
• This method works whether sound is recorded from a microphone array, or synthesized in software.
Technical Details:
Johns Hopkins researchers have developed an auditory headphone system to be overlaid with a real acoustic environment that the user can use spatial location as the user moves about a space. The development of a left and right ear head-related impulse response (HRIRs) headphones with inexpenensive head tracking device. This system uses a small Microelectromechanical Systems(MEMS) based system with a 3-axis accelerometer, 3-axis gyroscope, and 3-axis compass attached to a pair of headphones.
Looking for Partners:
To develop and commercialize the technology as an headphone based head-tracking systems to be use in gaming, entertainment, and virtual simulation.
