SMI Eye Tracking Glasses 2 Wireless - Easy, Robust and Efficient

SMI Eye Tracking Glasses 2 Wireless (SMI ETG 2w) are designed to record a person’s natural gaze behaviour in real-time in a broad range of applications - at a sampling rate up to 120 Hz and with outstanding robustness, mobility and ease of use. The ETG2w system with a glasses-type eye tracker and a lightweight smart recorder supports real-time data access and full study control via a wireless connection. The solution covers the whole process from study design to efficient analysis.

Use lightweight mobile eye tracking in everyday research scenarios

The glasses come with a lightweight SMI ETG 2w smart recorder based on a Samsung Galaxy Note 4. It captures eye gaze data of consumers, athletes, patients and other users allowing them to naturally perform their tasks at hand. The SMI ETG 2w has been proven by best-in-class customers with more than 100,000 participants worldwide.

NEWRecord native, binocular eye tracking up to 120 Hz

SMI’s high quality eye tracking technology provides native, binocular tracking up to 120 Hz sampling rate over the whole trackable field of view. Combined with a high definition scene camera and automatic parallax compensation this ensures accurate data over all distances.

Capture a person's natural gaze behavior

The Natural GazeTM design of the head gear for SMI ETG 2w is designed for natural recording of gaze behavior. It provides maximal peripheral and binocular vision - important for realistic depth perception and natural visual orientation. For best and robust fit, the glasses come with flexible temple arms.

Observe and annotate in real-time

With the wireless live capabilities of the SMI ETG 2w, professionals and scientists have full wireless control of a study. From a remote computer or tablet connected via Wi-Fi, operators can collect participant properties, perform a calibration, observe live gaze traces, transmit live audio and add live annotations to a user’s behaviour. For enhanced productivity, annotations can be used in SMI BeGaze powerful analysis software to efficiently focus data analysis on relevant sequences of the recorded data.

NEWSynchronize with EEG, motion tracking and other data streams

The SMI ETG 2w with mobile connectivity and network time synchronization allows for low latency synchronization with EEG, motion tracking, virtual reality and other external data streams - online and offline, with millisecond precision and no compromise on mobility.

Access live data with wireless SDK

Developers can access SMI’s enhanced wearable eye tracking platform and integrate mobile eye tracking data in custom applications and sensor networks. The 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.

Be efficient and productive in design, setup and recording and analysis

The SMI ETG 2w covers the whole process from study design, participant setup and data recording to efficient analysis. The software interface collects participant properties and questionnaires. Live feedback of calibration and live observation of the recording make it easy to control study progress even with demanding subject groups.

With its easy and calibrationless setup, the SMI ETG 2w is ready to start recordings of a participant within seconds. The smart recorder enables full mobility even in highly dynamic everyday research tasks.

SMI BeGaze analysis software and SMI Automated Semantic Gaze Mapping (ASGM) technology allow for efficient analysis of mobile eye tracking data.

Observe special user groups with snap-on corrective lenses and sun glasses

The magnetic snap-on corrective lenses for mobile eye tracking studies allow to cover the maximum user population. The SMI ETG 2w also comes with insertable sun glasses which ensure robust tracking in outdoor situations.
