The ETVision system is a high-speed binocular eye tracking solution designed for mobility, precision, and versatility in both indoor and outdoor environments. Built into a lightweight eyeglasses-style frame, the ETVision Eye Tracker allows researchers to monitor eye movements and collect comprehensive visual attention data during natural, real-world tasks.
Whether participants wear prescription glasses, contact lenses, or have uncorrected vision, the ETVision is designed for universal compatibility and comfort. Its compact form factor and ergonomic design ensure that the device can be worn for extended recording sessions without compromising data quality or participant mobility.
The ETVision Eye Tracker captures real-time data from both eyes, including pupil position (horizontal and vertical) and pupil diameter. Each eye is monitored separately using built-in miniature cameras embedded within the eyeglass frame. In addition, a forward-facing scene camera records the participant’s visual environment, while an integrated microphone, positioned above the brow line, captures ambient sound or spoken feedback.
This multimodal recording approach allows researchers to synchronize eye movement data with scene context and audio, enabling in-depth behavioral and cognitive analysis. Video and audio are recorded in parallel with eye movement data, with all recordings timestamped for seamless integration during post-processing.
The ETVision frame is engineered to provide an optimal and customizable fit for different facial structures. The system includes three interchangeable nosepieces that allow users to adjust the vertical positioning of the glasses on the face. To ensure accurate tracking, each side of the frame contains a rotating panel housing an eye camera and LED illuminators, which can be adjusted vertically to align with the participant’s eyes. These adjustments are especially useful when facial features cause the frame to sit at nonstandard angles or heights.
An optional clip-on visor is available for glare reduction in bright environments. The visor attaches via slots on the upper corners of the frame and can be removed easily when not needed.
The ETVision system supports both wireless streaming and standalone data logging. Data can be transmitted live to a computer over a wireless LAN connection, or recorded locally to a microSD card housed in the ETV-Controller unit. This flexibility makes it ideal for both laboratory and field research.
The ETV-Controller unit powers the system with a rechargeable Li-Po battery, providing over 5 hours of continuous recording in standard configurations. When using the onboard storage, researchers can typically record up to 2 hours of synchronized eye-tracking, video, and audio data, depending on configuration and resolution settings.
The ETVision includes an intuitive software interface that simplifies setup and calibration. Researchers can perform single-point or multi-point calibration routines tailored to the experiment’s accuracy requirements. The software also supports real-time monitoring and data visualization when operating in streaming mode, offering immediate feedback during setup or data collection.
The ETVision system consists of:
Optional accessories include the clip-on visor, additional nosepieces, and external batteries for extended use.
