Get a grip Slippage-robust and glint-free gaze estimation for real-time pervasive head-mounted eye tracking

, 2019
A key assumption conventionally made by flexible head-mounted eye-tracking systems is often invalid: The eye center does not remain stationary w.r.t. the eye camera due to slippage. For instance, eye-tracker slippage might happen due to head acceleration
