The ETVision system from Argus Science, provides high update rate and binocular measurement, with the ultimate in ease of use and complete mobility indoors or out.
ETVision builds upon our experience with lightweight, un-obtrusive eye trackers and takes these capabilities to the next level.
Conceived to allow the investigator to capture data in multiple ways over a longer period of time, the ETVision may be worn either by participants with uncorrected vision…or by participants wearing their own prescription glasses, or contacts. The intuitive interface allows for single point or multiple point calibration. Data is sent to a laptop PC via WiFi or LAN, or may be captured locally on a microSD card. Battery power allows recording time of well over 5 hours.
The system is designed to handle the increasingly diversified demands of eye tracking in a variety of applications including:
The participant simply puts on the “glasses” frames, which include the two eye cameras, near IR light sources, scene camera and microphone. The frames can be worn over prescription glasses and are connected with a standard HDMI cable to the ETVision Controller. The Controller is a linux based lightweight unit that may be carried either with a removable belt, or in the participants pocket or anywhere one might carry a cell phone.
The ETVision system can integrate with numerous commercially available position tracking systems to implement the Argus Science ET3Space function. Argus Science StimTrac function is also supported, along with Argus Science ETAnalysis software.
ETVision, combined with new Argus Science StimTrac (Stimulus Tracking) data analysis technology and the ETAnalysis program, allows use of one eye tracker for multiple applications which, in the past, would have required different types of eye tracker systems.
For example, in the case of a participant seated in front of a display monitor, the data analysis advantages afforded by a desk top eyetracker can now be realized with ETVision by using the optional Argus Science StimTrac (Stimulus Tracking) feature.
