ETVision System

- Mobile eye tracking system
- For indoor and outdoor research
- Intuitive interface
- Single and multi-point calibration
- Data is transferred to a laptop via Wi-Fi, LAN, micro SD card
- Battery power supply lasts for 5 hours of operation
- Bidirectional audio allows the researcher to talk to the participant and the participant to talk to the researcher during the task

- Eyewear can be worn over prescription glasses
- Frames include two eye cameras, near-infrared light sources, scene camera and microphone
- Connected via standard HDMI cable to the ETVision controller
- Linux-based controller can be worn on a detachable strap, in the participant's pocket or anywhere

- ETVision can be integrated with many position tracking systems to implement the function Argus Science ET3Space
- ETVision data can be processed using the comprehensive ETAnalysis application
- Data can be streamed over the network and also saved to a data file
- Data logging can also be controlled from an external device using network commands.
- The ETAnalysis application can be used to extract additional information from the recorded data

Key Features

Artificial Intelligence (AI) Object Detection
The AI ​​model can be used to automatically detect and track multiple objects in the scene image in real time and mark gaze periods. Custom AI models can be “trained” to recognize specific objects using an improved version of ETAnalysis.

Live Area of ​​Interest (LAOI) Tracking
The feature detection algorithm can be used to track the exact outline of objects of interest in the scene image in real time and mark gaze periods. When Gaze is on the LAOI, gaze position can be reported relative to a coordinate system defined on the object.

ET3Space
The ETVision system can integrate with a variety of commercially available position tracking systems to determine gaze lines relative to 3D, a “room” coordinate system, and gaze points on stationary surfaces in the environment.

Live Fixations/Blinks
Live and recorded data includes gaze points relative to the scene camera image, pupil diameters based on ellipse fit, fixations, upper and lower eyelid position, and blink detection.

ETPhone
An iOS or Android phone app called ETPhone can be used to view live video feeds from the ETVision eye camera and scene camera, to provide a target for automatic calibration, control SD card recording, and several other functions.

EEG
The optional controller synchronization feature provides TTL-level synchronization pulses directly from the controller to external devices such as EEG recording systems, enabling precise time synchronization of ETVision and EEG data files (or other external device).

Stationary Camera
Video from the external camera can be displayed in real time and synchronously recorded along with video from the eye camera and head-mounted scene camera.

180 Hz Eye Video Recording
ETVision can record video of both eyes at 180 fps. Using ETVision playback mode, you can review eye video frame by frame or use it to recalibrate and recalculate gaze.

Live Bar Graphs
ETVision can display real-time (“live”) bar graphs of statistics, including total time, number of fixations, and more, for each detected AI or LAOI object.
