Patent Alert: Sony's Prescription VR Glasses

April 10, 2019

 

 

US20190101980A1 was published by Sony that describes a head mounted display and prescription glasses to be worn with it. Instead of incorporating the eye tracking system in the HMD alone like their traditional headset, Sony decided to implement it in the prescription glasses as well. This could eliminate the image distortions created by the lens of the prescription glasses as seen before. The user information captured by the glasses is transmitted through a wireless signal to the HMD by the emitter. This signal is in the form of pulses of data that carry the gaze information to the HMD. Electro optical elements such as infrared LEDs are implemented in the glasses to illuminate the user's eyes.
