HEAD MOUNTED IMAGING APPARATUS WITH OPTICAL COUPLING
20170371160 · 2017-12-28 ·

A head-mounted imaging apparatus includes a frame that houses a left-eye and a right-eye imaging apparatus. Each imaging apparatus forms a virtual image to an eye of an observer and includes a projector, a planar waveguide, and an optical coupler. The projector is supported by a temple member of the frame and emits a central projected light beam along a projection axis. The planar waveguide accepts the projected light beam through an input aperture and forms an expanded light beam that is output from an output aperture and directed toward the observer's eye. The optical coupler receives the central projected light beam along a first axis that is at an obtuse angle with respect to the waveguide surface, and the optical coupler redirects the central projected light beam along a second axis that is at an acute angle with respect to the waveguide surface.

The system may include a processor and a memory storing instructions. In addition, the system may include a first lens including a first waveguide for displaying a first image and a second lens including a second waveguide for displaying a second image. Furthermore, the system may include a first projector associated with the first lens to propagate first display light associated with the first image, a second projector associated with the second lens to propagate second display light associated with the second image and a disparity sensing port to receive the first display light and the second display light to determine a disparity associated with the first image and the second image.

Information processing to indicate a position outside a display region

The present technology relates to an information processing device, an information processing method, and a program that can more exactly indicate a position outside a display region. An outside-display-region-position designation unit designates a position outside a display region of an image display unit, and a drawing/sound control unit controls output of a sound of an AR object from a sound output unit while moving the AR objet toward the designated position. The present technology can be applied to a wearable computer, for example, a glasses-type device having a pair of image display units for a left eye and a right eye.
