| Abstract: | In this thesis, we aim to investigate the potential of YET (Your Eye Tracker) as an ultra-low-budget do-it-yourself solution to make eye tracking technology more available and affordable. Our main objective is to systematically evaluate the accuracy and precision of YET compared to existing eye tracking systems. By conducting calibration tests and comparing data, we seek to determine the feasibility of YET for various applications. Employing a within-subject design, participants completed a calibration task before viewing stimuli displayed on both a white background (congruent with the calibration background) and a black background (incongruent with the calibration background). This variation aimed to examine the influence of screen background consistency on calibration accuracy. Additionally, three head-mounted lighting conditions (LED, near-infrared, and ambient lighting only) were tested to assess their effects on YET's performance under varying illumination. Results indicate that YET is able to achieve an accuracy close to established eye tracking systems at the center of the screen but shows reduced accuracy toward the outer edges of the screen. Incongruency of the screen´s background to the calibration screen resulted in a noticeable misalignment between stimuli and estimated gaze points whereas alignment was consistent in the congruent background condition. Variations in lighting conditions (LED, NIR, or no additional light) did not appear to impact YET’s performance. |
