If you're looking for software to download, it can be found in the "Releases" section on the right. Only a Windows binary is available pre-compiled at the moment.
This software is a free, open-source tool which can be used to validate the accuracy and precision of an eye tracker system. The tool works on Windows and should also work on Linux and OS-X, though this hasn't been tested. It has been designed to allow new trackers to be easily added and tested with minimal coding; the demo programs included with your eye tracker will probably contain all the code you need.
If you use this tool and add a new tracker, please submit a pull request to allow others to make use of your work.
If you use this software for research, please cite the following paper:

The number of dependencies has intentionally been kept small to allow the code
to be built and run with minimal fuss. The build is managed by cmake, with UI
components managed by OpenGL. Both of these are widely available.
On Windows, the easiest way to get up and running is to open the folder with
Visual Studio. If you don't have cmake or a C++ compiler installed, they can
be added using the Visual Studio Installer. OpenGL is available in Windows by
default.
On Linux, the only additional dependencies are the OpenGL and X11 development libraries. To install on a debian-based system, use the following:
sudo apt-get install -y libgl1-mesa-dev libglu1-mesa-dev libxi-dev
If you don't have cmake or C/C++ compilers installed, you'll need these too:
sudo apt-get install -y build-essential cmake
Since this project uses cmake, your build tool can change depending on your
environment. The default settings are listed below.
From Visual Studio, simply build the target TrackerValidation. This will
generate the build files (ninja by default) and run them. Nothing else to do.
cmake will generate Makefile files by default. From the root directory, run
the following to generate the files:
cmake -B build -S .
To compile, run:
cmake --build build --parallel 16 --config Release
Note that if you don't add/remove any source code, libraries or other
dependencies, then you only need to run make after each code change. If you
do change dependencies, you'll need to run cmake . from the root directory
again.
