Microsoft was granted 1 patent in 1 category: VR & AR (1).
The patent addresses display technology for head-mounted devices, specifically frame rate adaptation for virtual and mixed reality applications. The VR & AR patent covers a system that dynamically adjusts display refresh rates based on changes in critical flicker fusion threshold, enabling optimized visual quality during head-mounted device operation.
Microsoft's single VR/AR patent describes a display system for head-mounted devices that adjusts refresh rates based on how human eyes perceive flicker under different visual conditions. The technology monitors factors like brightness, contrast, and color in the displayed content, then modifies the frame rate in response to changes in the critical flicker fusion threshold, the point at which the human visual system stops perceiving individual flashes and sees continuous light. This approach connects biological visual perception research directly to display Hardware control, moving beyond conventional adaptive sync methods that typically respond to GPU rendering speeds or content motion rather than perceptual thresholds. By accounting for how stimulus attributes affect flicker detection, the system can maintain optimal visual quality across varying VR and mixed reality scenarios without defaulting to a static refresh rate.
