iView X™ HED

The fully mobile, head-mounted gaze tracker

Reliable mobility

The iView X™ HED is the latest generation mobile eye-tracking system, combining full freedom of movement with easy setup and efficient operation. Robust and reliable, the use of a lightweight headset and tablet PC makes it perfect for indoor and outdoor use.

Fully automated

Easily set up within minutes, the iView X™ HED features fully automatic tracking for instant results. Scene video recording in broadcast quality allows for seamless integration with video analysis packages, as well as customizable video overlays for gaze cursors, time stamps, trial information, logos, etc. The data and message recording includes pupil size and user messages from auxiliary devices, and this can be streamed online via a network or serial link to other systems.

Quantity & quality

The iView X™ HED optionally includes the Mobility Package for virtually unlimited working range and non-stop operation with additional batteries and an external charger. Another option is the Head Tracking Package for the quantitative recording of 3D gaze vectors in complex environments, such as simulators or virtual reality setups.
