The SMI iViewX™ RED is an eye tracking system with entirely novel properties. The system measures human gaze on a monitor, as well as on projection screens and newspapers to assess print media, websites, TV spots and designs. The SMI iViewX™ RED does not distract the user while offering high usability and modular flexibility. The implementation combines camera and infrared illumination in one housing. The design puts the system in a modern, factual context to the monitor and the environment. The eye tracking system is “invisibly” connected to the monitor and can also be mounted on a stand-alone foot.
