Pupil Capture

Pupil Capture is a cool tool that helps you track eye movements and gaze points. With the rise of wearable cameras, there's been a lot of buzz around egocentric vision and eye tracking. Why? Because our eyes are super important in how we see the world! By automatically analyzing what we look at, scientists can learn more about which objects catch our attention in different settings.

Understanding Egocentric Vision

Egocentric vision is a growing area in computer vision. It focuses on how we perceive things from our own viewpoint. The measurements you get from this perspective can give us neat insights into how our eyes, head, and hands work together. This info could really help out in medicine!

What is Pupil Capture?

Pupil Capture is an open-source app built to track pupil movement and gaze with great accuracy. To use it, you'll need to wear special pupil mobile eye tracking headsets. The developer offers hardware options, but if you're feeling crafty, you can even make your own headset! Just keep in mind that if you're not using this data for commercial purposes, DIY might be the way to go.

Getting Started with Pupil Capture

Before jumping into recording data, you'll want to calibrate your camera first. It's all about getting the right focus! Don't worry though; once you set up the world camera and hardware correctly, these settings will stick around until you unplug your headset.

Pupil Detection Made Easy

A key feature to keep an eye on (pun intended!) is pupil detection. Once you've got that red circle focused around the edge of your pupil, you're good to go! After calibrating both cameras and ensuring pupil detection works well, capturing data for your research becomes pretty straightforward.
