Tobii Pro, Reston, Va., launched Tobii Pro Nano, what is said to be the world’s smallest research-grade eye tracker.

Designed to use with portable screens, Tobii Pro Nano is ideal for researchers wanting to take their attention-based studies outside the lab environment.

Tobii Pro Nano plugs into the USB port of a Windows laptop or tablet and collects gaze data at 60 hertz (Hz). The data generated from the eye tracking provides unique insights on human behavior, which is useful in marketing and behavioral economics.
