SR Research, the makers of eye tracking hardware and software, have
released Pylink.
Pylink can be used with the Vision Egg!
According to SR Research:
Pylink allows for tracker control, real-time data access, and
external synchronization with eye data via custom messaging.
Many people find Python to be a simpler, yet still powerful,
alternative to C. Pylink can also be used in combination with the
excellent third party open source Vision Egg software; providing a
combined visual presentation and eye tracking scripting package.
Distributed with Pylink is a modified Vision Egg demo using realtime
tracker data to move a Gaussian-windowed grating in a gaze-contingent
fashion. Following this example, it should be easy to create other
VisionEgg/Pylink scripts for a variety of vision experiments involving
eye tracking.
