ECA Application Design: Augmented reality combined with eye-tracking technology based on Mobile device for myopia prevention

In daily life, with the popularity of mobile devices such as mobile phones and iPad, it is more and more common for children and adolescents to see myopia caused by long-term viewing of mobile device screens or failing to maintain a healthy visual distance. In response to this phenomenon and problem, we designed an intelligent eye care assistance system (ECA) based on mobile devices, which integrates web browsers and utilizes AR technology combined with depth camera technology. Compared with the current methods of controlling distance through ultrasonic sensors, infrared sensing devices, etc., the ECA system is more convenient to use and does not require any additional hardware equipment. The system implements the method of controlling the distance between the user and the mobile device screen through three steps: real-time eye tracking, distance measurement, and reminder for the user. And for the problem of users' long-term viewing of mobile device screens, we added a time reminder control function in the system design to better prevent myopia and protect users' eyesight. This paper proposes a common framework for an intelligent eye-protection ECA system to prevent various ophthalmic diseases [1] caused by short viewing distance watching mobile devices screens, including cataracts, glaucoma, retinal detachment, and myopic macular degeneration.
