Eye Tracking Glasses

Easy, robust & versatile mobile eye tracking solution


SMI Eye Tracking Glasses 2W with HD Scene Camera

Now researchers can easily record, synchronize, and analyze biometric data and mobile eye tracking data during interactive tasks using SMI Eye Tracking Glasses 2 Wireless (ETG 2w) by SensoMotoric Instruments (SMI) BIOPAC wireless, wearable BioNomadix Logger, and BIOPAC AcqKnowledge software. The ETG 2w eye tracking glasses record a person’s natural gaze behavior in real time, in a broad range of applications, and with outstanding robustness, mobility and ease of use. BIOPAC wireless hardware and software deliver world-class, research-quality biometric data in an easy-to-analyze format with extensive analysis tools.

The ETG 2w comes with a slim and lightweight ETG smart recorder which ensures full wireless data access with no compromise of mobility. iViewETG eye tracking software. The PRO also includes SMI BeGaze qualitative analysis (event detection, event overlay on video, other features) and quantitative analysis features a multi-user semantic gaze mapping module and the ability to aggregate multiple participant gaze and behavioral data onto target areas.

SMI mobile eye tracking is ideal for use with BIOPAC’s BioNomadix Logger and BIOPAC MP systems with AcqKnowledge.

AcqKnowledge software allows the playback of the SMI eye tracking video file and the video is synchronized  with the physiological data. Place the cursor anywhere in the physiological data and the video will jump to the corresponding frame in the video. The cursor automatically advances through the physiological data file marking the corresponding spot when the video is played.
