Pupil Capture

Along with the rise in popularity of wearable cameras, there has also been an increasing interest in researching the egocentric vision and eye tracking. Considering that a person senses the visual world through eye fixations, the automatic analysis of the first-person perspective can provide scientists with clues about what constitute the most salient objects in a landscape.

It is important to note that egocentric vision is one of the emerging fields of computer vision and the first-person perspective measurements can provide valuable insight regarding eye-head and eye-hand coordination. As a consequence, it could lead to major breakthroughs in the medical field.

Pupil Capture is an open-source application designed to capture the pupil movement, track the gaze and track markers in the subject's environment with high precision. You should know that the program requires you to wear a pupil mobile eye tracking headsets. While the developer can provide you with the hardware, you can also craft it yourself, especially if you do not intend to use the data for commercial clients.

Before you can start recording data, you should first take the time to calibrate the camera and, although obtaining the right focus entails configuring the world camera and the hardware, the good news is that the settings are saved until you unplug the headset.

A further noteworthy element to account for is the pupil detection, an option you can be sure it is saved once you get the red circle focused around the edge of the pupil. After you calibrated the two cameras and got the pupil detection, you can start capturing data for your research without too much effort.
