The lightweight device based on a Samsung Galaxy Note 4 adds more freedom of movement and mobile connectivity options to daily life research and application scenarios. It captures eye gaze data of consumers, athletes, patients and other users allowing them to naturally perform their tasks at hand.

With its live trigger support, the smart recorder allows for easy synchronization of visual attention with biometrics, motion tracking and other external data streams with no compromise on mobility. The wireless SDK for online data access also makes SMI’s Eye Tracking Glasses the perfect eye tracking platform for custom, multi-sensor applications.

SMI Eye Tracking Glasses are designed to capture a person’s gaze in a natural environment, e.g. in a supermarket, at a work place or in other daily life scenarios. Via wireless control from a remote computer, operators can observe live gaze traces in a scene video and add live annotations on a user’s behaviour.

Now, the slim and lightweight ETG smart recorder with a local user interface and full wireless data access makes mobile eye tracking even easier to implement in stand-alone as well as in multi-sensor scenarios.

As the research on emotional and cognitive engagement of consumers, users or trainees is moving into real-world scenarios, researchers seek to integrate various sensors into multimodal scenarios.

With the mobile connectivity of the ETG smart recorder, they can even better use SMI’s Eye Tracking Glasses in combination with EEG, GSR, NIRS, heart rate or others in mobile settings. The same applies to sports scientists seeking to analyze eye and body movements in order to understand athletes’ performance. Also, mobile gaze and motion data helps medical professionals to advance behavioral and neurological diagnosis and rehabilitation.

Developers can easily access SMI’s enhanced wearable eye tracking platform and integrate mobile eye tracking data in custom applications and sensor networks via the SMI SDK. SMI’s wireless SDK feeds a real-time stream of gaze, pupil data and eye tracking video into connected applications.

Wireless logging of incoming trigger messages supports synchronization with events in other data streams. To facilitate synchronization, SMI plug-ins are available for standard communication protocols such as Lab Streaming Layer or VRPN. The SMI ETG also supports multisensory research with specific application modules.

Magnus Berlander, CTO at Qualisys: "We decided to add eye tracking data to our motion capture software, Qualisys Track Manager, because it allows our customers to gain a better understanding of the interplay of visual information input, human motion, cognitive skills and learning."
