Tobii Eye Tracking Device and Development of Unity Applications

Technology companies continuously innovate and develop new devices and software solutions that facilitate user interaction with smart technologies. The pace of development varies, with some devices advancing more rapidly than others. This article focuses on developing applications for the Tobii Eye Tracking device, which allows users to control a computer solely with their eye movements without needing a mouse or keyboard. We present two applications we have developed using the Unity game engine. These applications can assist individuals with disabilities in communicating via a computer or serve as a demonstration of how eye-tracking technology can be used for gaming. The first application introduces users to this technology. The player moves across the screen and attempts to collect points by focusing on green balls while avoiding red ones. The second application focuses on writing and drawing using only eye movements. This application is particularly useful for individuals with disabilities, providing them with an accessible way to interact with a computer
