Ergonomic-Centric Holography: Optimizing Realism, Immersion, and Comfort for Holographic Display

Ergonomic-centric holography is introduced, an algorithmic framework that simultaneously optimizes for realistic incoherent defocus, unrestricted pupil movements in the eye box, and high-order diffractions for filtering-free holography. The proposed method outperforms prior algorithms on holographic display prototypes operating in unfiltered and pupil-mimicking modes, offering the potential to enhance next-generation virtual and augmented reality experiences. A computational framework is designed to enhance computer-generated holography (CGH)'s ergonomics, focusing on realism, immersion, and comfort. The framework optimizes a hologram that produces an incoherent out-of-focus response matching how real-world objects defocus (realism), minimizes the image quality variation across the entire theoretical eye box to allow unrestricted pupil movement with motion parallax (immersion), and simultaneously model high-order diffractions to eliminate the need for optical filtering and facilitate the design of a slim and compact display (comfort). image
