Design of Head mounted displays

This tutorial summarizes the design of head mounted displays. The HMD design is inherently an interdisciplinary subject fusing optical engineering, optical materials, manufacturing techniques, user interface design, computer science, human perception, and physiology for assessing the displays. The report focuses on the optical designs, human factors of HMD. Currently there are two types of microdisplay based HMD using different optics--eye piece optics and projective optics. We will talk about many key factors that associate the design of the HMD, such as the image FOV, resolution and pupil size. The human factors of HMD, which is closely related with prototyping process, will also be discussed.
