This paper presents a method for enhancing the visual response of head-mounted displays (HMDs) by using view-dependent control over lighting. The technique dynamically amplifies light intensity based on the user's gaze direction to compensate for the narrow field of view and limited dynamic range of HMDs, demonstrating its effectiveness in simulating blinding lights in dark virtual environments.
