Point of Regard is an open source (GPL2) head and eye tracking software making use of the Polhemus FASTRAK and ISCAN eyetracker hardware. This currently still makes use of firmware loaded from a Microsoft Window's machine and the provided software for eye image calculations. The project provides:
- Driver for USB Polhemus FASTRAK which tracks the position (X, Y, Z) and orientation (azimuth, elevation, roll) of a small receiver as it moves through space.
- Driver for reading from the serial port the angle of the eye from an ISCAN eyetracker.
- Library to calculate the point of interception on the defined screens. This allows you to display the point a user is looking at with single screens, multiple screens, CAVE environments and multiple screens separated around the environment
- A GTK based interface to control the core library
