You have found the first guide to head-mounted displays (HMDs) that places the emphasis where it belongs - on the end-user. This volume addresses key disciplines for future head-mounted virtual reality (VR), industrial and military display systems. It gives you a solid understanding of factors critical to end-user acceptance: user-centered design, imaging and optics, anthropometry, safety, human factors, visual perception, and system testing. HMD visual displays, image alignment, head and neck strain, and brain-actuated control are explored in depth. You also have access to a superb categorization of HMD optical designs, and a state-of-the-art model for stereoscopic viewing. From basic optical parameters to supporting HMDs with head-tracking data, this guide covers the important aspects of designing cutting-edge HMDs for the designer, user, and buyer of next-generation devices and systems.
