Are sonar-equipped glasses the future of VR body tracking? Find out the potential downsides and benefits

1. Improved upper-body tracking: Sonar-equipped glasses have the potential to significantly enhance the accuracy and precision of upper-body tracking in virtual reality and other applications.
2. Wearable and convenient: Being attached to a generic pair of eyeglasses, the sonar system is a wearable technology that is easy to use and does not require additional bulky equipment.
3. Wide range of applications: Sonar-equipped glasses can be used in various fields, such as gaming, computer animation, rehabilitation, and training simulations, offering a versatile solution for multiple industries.
4. Non-invasive: Unlike some other tracking technologies, such as motion capture suits, sonar-equipped glasses do not require body sensors or markers, making it a less invasive option.
5. Potentially low cost: Integrating sonar systems into existing eyeglasses may be a more cost-effective solution compared to developing entirely new tracking devices.

1. Limited range and accuracy: Sonar technology has limitations, such as reduced accuracy in certain conditions and a limited tracking range. This might affect the overall tracking performance and user experience.
2. Potential privacy concerns: With sonar systems, there is a possibility that personal spaces and privacy could be compromised due to the use of sound waves to track body movements.
3. Learning curve: Adapting to sonar-equipped glasses might require users to learn new tracking methods, which could take time and slow down initial usage and adoption rates.
4. Compatibility issues: As sonar-equipped glasses would be an addition to existing VR systems, compatibility with different hardware and software platforms can be a challenge.
5. Potential physical discomfort: Wearing glasses with additional technology may cause discomfort to some users, especially those who already wear prescription glasses or have limited tolerance for additional weight and accessories.


A team of researchers from Cornell University has created a unique wearable device that incorporates batlike sonar technology. This innovative device has the potential to enhance upper-body tracking in virtual reality and other applications. The researchers at Cornell modified a regular pair of eyeglasses to include a small sonar system, effectively showcasing its capabilities.
