Without an eye tracking device, the Tobii Pro Sprint app allows you to live view and record usability test sessions of participants.
In order to get the full Pro Sprint experience and see what your participants see, you will need an eye tracking device. Pro Sprint currently supports the Tobii Eye Tracker 4C, both Sprint Edition and regular versions.
