The Tobii Pro Eye Tracker enables you to output eye tracker position and gaze direction, with binocular gaze tracking. Its nodes (Tobii Pro Glasses 2 and Tobii Pro Glasses 3) are displayed under the Devices node.
The Tobii Pro Eye Tracker is compatible with current Vicon cameras. A minimum of two cameras are required for use with the system. Note that Nexus supports the use of only one pair of glasses at a time.
For information on setting up a Vicon system that includes Tobii Eye Tracker, see Use Tobii Eye Tracker with Nexus.

| Name | Enter a display name for the device. Default: Blank |
| Delay Compensation (s) | The delay compensation value (in seconds). Many eye tracking systems, particularly new wireless systems, may introduce a small delay in transmission of data. This delay may cause a misalignment between Vicon frames of data and eye tracking frames of data. The Delay Compensation slider bar enables you to correct this difference and properly align Vicon data with eye tracking data. To find the amount of delay for an eye tracking system, refer to the operating manual of the eye tracking system. All devices have a delay compensation value which adjusts the synchronization offset between the device and the Vicon data. Analog data collected with the Vicon connectivity devices should already be synchronized, so this value should be set at 0. Values can be set between -10 and 10. Default: 0 |
