The research area of foveated rendering focuses on optimizing the rendering of virtual reality (VR) or augmented reality (AR) environments by mimicking the behavior of the human eye. The fovea is the central region of the eye where visual acuity is highest, while peripheral vision is less sharp. By concentrating rendering resources on the foveal region and reducing detail in the periphery, foveated rendering can improve performance and reduce the computational load on hardware, making it particularly suited for resource-intensive applications like VR and AR. Researchers in this area explore techniques for accurately simulating foveal vision, developing algorithms for dynamic rendering based on eye tracking, and optimizing graphics pipelines to efficiently allocate resources based on visual attention.
