Using Smartphones creates unique challenges for eye-tracking because users handle their phones in many different ways. Unlike desktops, where the screen stays in one position, people often change how they hold their devices, or move them closer or farther away from their faces. RealEye’s system adapts to these conditions to provide reliable gaze tracking, with consideration to how users interact with their phones.
To evaluate the Accuracy of RealEye on Smartphones, we performed a validation study that involved grid-based tasks (learn more in our Whitepaper). The Accuracy means how close the system’s prediction is to the actual point on the screen where a person is looking.
The results of the study showed that the average accuracy on Smartphones is ≈ 56 pixels. This means that on the horizontal axis, the average accuracy is around 1/6 of the screen width, while on the vertical axis, it is approximately 1/10 of the screen height. Additionally, 71% of the data landed within 75 pixels, 87% within 100 pixels, and 95% within 125 pixels.
