  • Patent number: 10152141
    Abstract: A head-worn computer includes a camera system positioned to capture a surrounding environment in front of a user, a processor that identifies a position of a plurality of light emitters mounted on a hand-held controller from images captured by the camera system and tracks the position of the plurality of light emitters as the hand-held controller moves in the surrounding environment and interprets the tracked position as positional changes of the hand-held controller. The processor uses the position of the plurality of light emitters as markers in three dimensional space, the markers used as an anchor for virtual content presented in a see-through display of the head-worn computer.

  • Patent number: 10134321
    Abstract: A display device includes a display panel, a driver, a detector, and an acquisition part. The driver drives the display panel based on a video signal. The detector obtains a first detection value by detecting reflective light from reflective media, which occurs when ambient light is irradiated to reflective media, while obtaining a second detection value by detecting reflective light from reflective media, which occurs when the display panel irradiates its display light to reflective media. The driver corrects a drive value for the display panel such that the second detection value approaches the first detection value or such that the chromaticity represented by the second detection value approaches the chromaticity represented by the first detection value, and therefore the acquisition part acquires information concerning the color temperature of ambient light based on the corrected drive value.

    Abstract: To enable a state of an object to be changed based on a relationship between a line of sight of a user wearing a head-mounted display and a position of the object arranged in a virtual space, a specific object is arranged at a predetermined position in the virtual space. A determination is made whether the specific object is located outside a certain range from the line of sight of the user wearing the head-mounted display for a first predetermined period. Then, when the specific object is located outside the certain range from the line of sight of the user for the first predetermined period, a sound associated with the specific object is generated.
