I’m developing the app which records programmer’s gaze area of source codes by using EyeX SDK. Most of the researchers usually use high spec eye tracking device like X60/X120, but it is too expensive easily to get one.
The prototype consists of two programs. One is to get fixation data from EyeX Controller by using the MinimalGazeDataStream included in Tobii EyeX SDK for .NET 0.32 with a few modification. The other is to visualize the fixation points by using Processing. Two programs communicate with each other using TCP/IP socket.
Currently I am working on my master thesis using tobii eye tracker. In my project I need to visualize the fixation points by using Processing as you had mentioned. Can you please share with me the methodology you had used in your source code.
I don’t use EyeX any more, especially in the research that needs to analyze EyeX’s gaze data because its strict license policy, see http://developer.tobii.com/license-agreement/, and the project files are missing…I’m sorry I couldn’t help you.
