Senior Software Engineer (VR)
  • I had the privilege of working for a company specializing in cutting-edge eye-tracking technology for Virtual Reality (VR) experiences. Their eye-tracking solution was so impressive that it garnered the attention of industry leaders. As a key contributor to this endeavor, I took on the responsibility of developing the entire VR experience using Unity. This encompassed everything from designing the immersive environment to creating the intricate network programming required for real-time synchronization.
  • The focus of this project involved showcasing their remarkable eye-tracking solution by creating an innovative multiuser VR environment. Unlike traditional VR experiences designed for single users, I conceptualized and developed an immersive shared VR environment. In this groundbreaking setup, two users physically located in the same space could also interact within a shared virtual space.
  • This shared VR experience not only offered full 6 Degrees of Freedom (6 DOF) immersion but also introduced the concept of avatars. Users were represented within the virtual world by avatars, and what truly set this project apart was the synchronization of the avatars' eye movements with the users' real eye movements.
  • Through this project, I showcased the potential of eye tracking in VR, pushing the boundaries of what was possible in shared virtual environments.
