Eye tracking in virtual reality refers to the technology that allows for the precise and real-time monitoring of a user’s eye movements while they are immersed in a virtual environment. This advanced technology uses specialized sensors and cameras to track the position and movement of the eyes, providing valuable data on where the user is looking and how their gaze is shifting within the virtual world. This information can then be used to enhance the user’s experience by adjusting the display and interactions accordingly, creating a more immersive and natural virtual reality experience. Eye tracking in virtual reality has numerous applications, from improving the accuracy and efficiency of virtual reality gaming to aiding in medical research and training simulations.
