Fig. 2: Comparison between accuracy of Tobii glasses vs. our model.
From: Accelerating eye movement research via accurate and affordable smartphone eye tracking
Study setup shows the four experimental conditions: Participant (an author for visualization purposes) views stimuli on the phone (mounted on a device stand) while wearing Tobii glasses (a) and without (b). c, d Similar to the above, but participant holds the phone in the hand. e, f Accuracy of specialized eye tracker (Tobii glasses) vs. our smartphone eye tracker (mean ± s.e.m., n = 13 participants) for the device stand and hand-held settings. Statistical comparison shows no significant difference in accuracy across both settings (device stand: t(12) = −2.12, p = 0.06; hand-held: t(12) = −1.53, p = 0.15; two-tailed paired t-test).
