Computational Display for Virtual and Augmented Reality

[摘要] Wearable displays for virtual & augmented reality face tremendous challenges, including: Near-Eye Display: how to put a display as close to the eye as a pair of eyeglasses, where we cannot bring it into focus? Field of view: how to fill the user's entire vision with displayed content? Resolution: how to fill that wide field of view with enough pixels, and how to render all of those pixels? A "brute force" display would require 10,000×8,000 pixels per eye! Bulk: displays should be as unobtrusive as sunglasses, but optics dictate that most VR displays today are bigger than ski goggles. Focus cues: today's VR displays provide binocular display but only a fixed optical depth, thus missing the monocular depth cues from defocus blur and introducing vergence-accommodation conflict. To overcome these challenges requires understanding and innovation in vision science, optics, display technology, and computer graphics.
