摘要： An optical system has an aperture through which virtual and real-world images are viewable along a viewing axis. The optical system may be incorporated into a head-mounted display (HMD). By illuminating a viewing location with an infrared light source, an eye pupil may be illuminated. Infrared light is reflected from the viewing location and is collected with a proximal beam splitter. An image former is configured to reflect at least a portion of the visible light pattern generated by the display panel to form the virtual image and transmit at least a portion of the collected infrared light. The transmitted infrared light may be imaged by a camera. The HMD may use images from the camera to provide, for example, context-sensitive virtual images to a wearer.

摘要： An optical system includes a display panel, an image former, a viewing window, a proximal beam splitter, and a distal beam splitter. The display panel is configured to generate a light pattern. The image former is configured to form a virtual image from the light pattern generated by the display panel. The viewing window is configured to allow outside light in from outside of the optical system. The virtual image and the outside light are viewable along a viewing axis extending through the proximal beam splitter. The distal beam splitter is optically coupled to the display panel and the proximal beam splitter and has a beam-splitting interface in a plane that is parallel to the viewing axis. A camera may also be optically coupled to the distal beam splitter so as to be able to receive a portion of the outside light that is viewable along the viewing axis.

摘要： An optical system has an aperture through which virtual and real-world images are viewable along a viewing axis. The optical system may be incorporated into a head-mounted display (HMD). By modulating the length of the optical path along an optical axis within the optical system, the virtual image may appear to be at different distances away from the HMD wearer. The wearable computer of the HMD may be used to control the length of the optical path. The length of the optical path may be modulated using, for example, a piezoelectric actuator or stepper motor. By determining the distance to an object with respect to the HMD using a range-finder or autofocus camera, the virtual images may be controlled to appear at various distances and locations in relation to the target object and/or HMD wearer.

摘要： Disclosed are methods and devices for rendering interactions between virtual and physical objects on a substantially transparent display are disclosed. In one embodiment, the method includes displaying a user-interface on a substantially transparent display of a wearable computing device. The method further includes displaying a virtual object in the view region at a focal length along a first line of sight and detecting a physical object at a physical distance along a second line of sight. The method still further includes determining that a relationship between the focal length and the physical distance is such that the virtual object and the physical object appear substantially co-located in a user-view through the view region and, responsive to the determination, initiating a collision action between the virtual object and the physical object.
