Researchers at Cornell University<\/a> have developed a wearable with batlike sonar that could improve upper-body tracking in virtual reality and other applications. The Cornell team fitted a generic pair of eyeglasses with a tiny sonar system, demonstrating how acoustic signals can be used instead of cameras to capture the body\u2019s movement.\u00a0<\/p>\n

Not only would sonar be more efficient in terms of battery consumption, the team told the Cornell Chronicle<\/em>, but it would also do away with the privacy risks that come with headsets\u2019 externally facing cameras. The system, dubbed PoseSonic, uses two pairs of microphones and speakers to send and receive acoustic signals, according to a recently published paper<\/a>. With help from their deep learning model, it can then estimate 3D poses at nine different points \u2014 the shoulders, elbows, wrists, hips and nose \u2014 as these signals bounce off the upper body.<\/p>\n

The team tested it both in the lab and \u201csemi-in-the-wild,\u201d and found it wasn\u2019t negatively affected by environmental noise in any significant way. With this technique, \u201cwe use less instrumentation on the body, which is more practical, and battery performance is significantly better for everyday use,\u201d senior author Cheng Zhang told the Cornell Chronicle. <\/em><\/p>\n

In addition to its potential use in augmented and virtual reality, the researchers say sonar could make for better health tracking by capturing more detailed information on the body\u2019s movements. They\u2019ve only got the upper-body covered at the moment, though \u2014 VR legs continue to elude us.<\/p>\n
