How much is enough? The human factors of field-of-view in head-mounted displays

摘要

Originally developed for military applications, head-mounted displays (HMD) are becoming more common for commercial virtual and augmented reality applications. One of the fundamental requirements of an HMD is the field of view (FOV), the apparent angular size of the virtual image as seen by the user. The size of the FOV has a major impact on the overall bulk, weight, resolution, cost and implied value of the HMD, so careful consideration must be given when determining how large it should be. There are key visual human factors guidelines that suggest how the field of view will allow the user to accomplish their specific tasks. These will be addressed in this paper.
