Presentation transcript:

Choosing an eye tracker Desktop mount  high sampling rate (up to 2000 Hz)  high precision and resolution  uncomfortable for writing Choosing an eye tracking device is a balance between performance, participant comfort and setup constrains. Some possible adaptation ? April 2012, Mshs, University of Poitiers, France

Remote mount :  low (30 Hz) to high sampling rate (up to 1000 Hz)  medium precision and resolution  comfortable for writing But problems to setup for writing:  with these systems, eye must be “filmed by under” ( upper eyelid )  arm can pass between camera and eye causing temporary (but frequent) lost of eye picture April 2012, Mshs, University of Poitiers, France

Head mounted  low (60 Hz) to medium sampling rate (up to 500 Hz)  medium precision and resolution  comfortable for writing April 2012, Mshs, University of Poitiers, France
