Title:

HEAD MOUNTED DISPLAY

Document Type and Number:

WIPO Patent Application WO/2016/132974

Kind Code:

A1

Abstract:

A head mounted display (HMD) is provided with a frame worn on the head of an observer and supporting an optical unit, and a position adjusting mechanism. The position adjusting mechanism adjusts the position, in a vertical direction, of the optical unit by moving a nose-pad portion in the vertical direction relative to the frame. The optical unit includes: an observation optical system positioned in front of the eyes of the observer to cause light representing an image generated by an image generation unit to be diffracted and reflected by a hologram optical element in the direction of the observer's pupil, thereby enabling the observer to observe a virtual image of the image; and a rotating mechanism for causing the optical unit to rotate about an axis along the eye-width direction of the observer and to be held in an arbitrarily defined position.
