Introduction to Arrington ViewPoint EyeTracking Software

NordicNeuroLab has formally tested the VisualSystem HD for compatibility with the ViewPoint EyeTracker software by Arrington Research, Inc.

The Arrington ViewPoint Eyetracker provides a complete eye movement evaluation environment that includes integrated stimulus presentation, simultaneous eye movement and pupil diameter monitoring (monocular and binocular), and a software development kit (SDK) for communication with third party applications in real time.

Equipment Required

The built-in eye-tracking cameras of the VSHD operate independently of one another with their own dedicated HDMI input. These HDMI cables connect from the NNL Control Room Interface (CRI) to independent composite video converters.

The CRI HDMI inputs for eye-tracking are circled in red.

The Arrington 2.0 USB Silverbox is required when purchasing the ViewPoint software.

When using binocular eye tracking, the converters will be connected directly to the Eye A and Eye B BNC connectors on the Arrington 2.0 USB Silverbox via BNC cables and a BNC (female) to RCA (male) adapter. When performing monocular eye-tracking, 1 video converter, BNC cable, and BNC to RCA adapter will be needed to connect to the Eye A output on the Silverbox.

The Arrington USB 2.0 Silverbox is connected to the video converters via BNC cables and the BNC to RCA adapters. The video converters link to the CRI through the HDMI cables.

*Note: The video converters are powered by the attached USB cables which will need to be connected to a USB port on the user computer.

System Schematic

The visual stimuli are sent to the VSHD goggles via HDMI and fiber signal. Through the dual HD OLED screens, the patient experiences stimuli in either 2D or 3D. As the patient is viewing the stimuli, the infrared (IR) LEDs illuminate the eyes and create glints. The integrated eye-tracking cameras record the eyes\' images and send the signals from the VSHD back to the CRI. In combination with the equipment mentioned above, the Arrington USB 2.0 Silverbox captures the digital signal and applies it with image segmentation algorithms to locate the areas of the pupils and glints for monitoring and recording of eye movement and pupil dilation.
