Recently, we published a prototype for gaze-guided object classification at UbiComp conference 2016. This topic also raised interest of Pupil Labs, the manufacturer of the applied eye tracking device.
Recent advances in eye tracking technologies opened the way to design novel attention-based user interfaces. This is promising for pro-active and assistive technologies for cyber-physical systems in the domains of, e.g., healthcare and industry 4.0. Prior approaches to recognize a user’s attention are usually limited to the raw gaze signal or sensors in instrumented environments. We propose a system that (1) incorporates the gaze signal and the egocentric camera of the eye tracker to identify the objects the user focuses at; (2) employs object classification based on deep learning which we recompiled for our purposes on a GPU-based image classification server; (3) detects whether the user actually draws attention to that object; and (4) combines these modules for constructing episodic memories of egocentric events in real-time.
