Tracking the user's gaze direction is crucial for augmented reality devices. While typically viewed as part of the user control interface, it is also essential for accurately projecting images in various systems and can be utilized to create peripheral vision effects and other applications. Current solutions primarily rely on computer vision techniques to analyze eye photos, with some advanced methods incorporating acoustic sensors or measuring the inductance of electrical loops integrated into contact lenses to enhance measurement precision.
In our study, to enhance eye tracking sensitivity, we have integrated a stereogram within the contact lens. This innovative approach leverages the dependence of the apparent position of a stereoscopic image on eye position, enabling reconstruction of the latter based on this effect. Our implementation of the stereogram utilizes the parallax barrier, which makes it passive, completely autonomous device. This novel approach not only paves the way for enhancement of eye tracking precision but also holds potential for other applications, such as serving as an identification mark for cybersecurity purposes.
