Amazing stuff! From smartphone, to smart watches, to smart eyeglasses ...
When can my thoughts and gaze operate my laptop! I would be wasting much less time clicking, taking screen shots, changing menus etc.!
"... The technology is small enough to fit on commercial smartglasses or virtual reality (VR) or augmented reality (AR) headsets, yet consumes significantly less power than similar tools using cameras. ..."
From the abstract:
"In this paper, we present GazeTrak, the first acoustic-based eye tracking system on glasses. Our system only needs one speaker and four microphones attached to each side of the glasses. These acoustic sensors capture the formations of the eyeballs and the surrounding areas by emitting encoded inaudible sound towards eyeballs and receiving the reflected signals. These reflected signals are further processed to calculate the echo profiles, which are fed to a customized deep learning pipeline to continuously infer the gaze position. In a user study with 20 participants, GazeTrak achieves an accuracy of 3.6° within the same remounting session and 4.9° across different sessions with a refreshing rate of 83.3 Hz and a power signature of 287.9 mW. Furthermore, we report the performance of our gaze tracking system fully implemented on an MCU with a low-power CNN accelerator (MAX78002). In this configuration, the system runs at up to 83.3 Hz and has a total power signature of 95.4 mW with a 30 Hz FPS."
