Imagine a future where smart glasses can accurately track your movements without the need for cameras. Scientists at Cornell University have developed a groundbreaking technology called “PoseSonic” that utilizes micro sonar and artificial intelligence to create an echo profile image of the wearer. This innovation has the potential to revolutionize the smart glasses industry by enhancing privacy, improving accuracy, and reducing production costs.<\/p>\n
PoseSonic: A New Era in Smart Glasses Technology
\nPoseSonic combines micro sonar, powered by CHIRP technology, with AI to capture an accurate echo profile image of the wearer. The micro sonar captures sound waves that are inaudible to humans, allowing for precise tracking of body movements. The technology has been successfully tested and published in the journal ACM Digital Library.<\/p>\n
Cheng Zhang, an assistant professor at Cornell and co-author of the study, believes that PoseSonic offers tremendous potential as a future sensing solution for wearables. Zhang highlights the advantages of sonar-based tracking over camera-based solutions, including improved privacy, cost-effectiveness, and efficiency.<\/p>\n
Enhanced Privacy and Affordability
\nCurrent augmented reality smart glasses on the market rely on cameras to track wearers’ movements. However, continuous video recording drains the battery quickly and raises privacy concerns. In contrast, sonar-based tracking is not only more affordable and efficient but also less invasive and privacy-conscious.<\/p>\n
PoseSonic utilizes microphones, speakers, a microprocessor, Bluetooth module, battery, and sensors. The prototype was created for less than $40, and with further manufacturing at scale, the cost could be reduced even further. In comparison, the ill-fated Google Glass cost $152 to make a decade ago.<\/p>\n
How PoseSonic Works
\nThe speakers fitted alongside the microphones emit sound waves that bounce off the wearer’s body and return to the microphones. The microprocessor then generates a profile image, which is fed into an AI model that estimates the 3D positions of nine body joints, including the shoulders, elbows, wrists, hips, and nose. Unlike other wearable systems, PoseSonic’s algorithm can work on any user without requiring specific training.<\/p>\n
Extended Battery Life and Future Applications
\nDue to the lower power consumption of audio equipment compared to cameras, PoseSonic can run on smart glasses for over 20 hours continuously. This extended battery life opens up new possibilities for integrating the technology into AR-enabled wearable devices without compromising comfort or adding bulkiness.<\/p>\n
Furthermore, the use of sonar technology enhances privacy. The algorithm processes only the sound waves it produces, eliminating the need for capturing images or using external sounds. Additionally, the data can be processed locally on the wearer’s smartphone, reducing the risk of interception.<\/p>\n
The future of smart glasses may lie in sonar-based tracking technology. PoseSonic, developed by scientists at Cornell University, offers a promising solution that combines micro sonar and AI to accurately track the movements of wearers. This innovation not only enhances privacy and affordability but also opens up new possibilities for monitoring behavior and providing detailed feedback during physical activities. As the world of augmented reality continues to evolve, PoseSonic represents a significant step forward in creating more advanced and user-friendly smart glasses.<\/p>\n","protected":false},"excerpt":{"rendered":"
