Pupil Capture is an open-source software developed by Pupil Labs for real-time eye tracking and gaze estimation. It serves as the primary interface for capturing, viewing, and processing eye tracking data from Pupil Labs hardware. Core Technology
The software relies on two main components to calculate where a person is looking.
Eye Cameras: Dark-pupil illumination and machine learning algorithms detect the pupil ellipse in real time.
World Camera: A forward-facing camera captures the user’s field of view.
Calibration: Geometry-based or polynomial mapping matches the pupil positions to specific pixels in the world video.
Open Source: The Python-based source code allows global developers to modify and extend its features. System Setup
Setting up Pupil Capture requires connecting compatible hardware and configuring the software environment.
Hardware: Plug the Pupil Core headset or compatible DIY eye tracker into a computer via USB.
Software: Download the installer for Windows, macOS, or Linux from the official GitHub repository.
Driver Installation: Windows users must install specific USB drivers using tools like Zadig for the cameras to register.
Video Configuration: Open the software and select the correct frame rates and resolutions for the eye and world cameras.
Calibration Run: Execute a calibration routine by tracking a moving marker on the screen or in the physical world. Primary Uses
Researchers and developers across multiple industries utilize Pupil Capture for high-fidelity gaze data.
Academic Research: Scientists study visual attention, cognitive load, and reading patterns in psychology and neuroscience.
UX/UI Design: Designers track user gaze on websites and applications to optimize layouts and remove friction.
VR and AR: Developers integrate the software with virtual reality headsets for foveated rendering and hands-free control.
Assistive Tech: Engineers build communication tools that allow individuals with motor impairments to type or navigate using eye movements.
