Patent number: 9588341Abstract: The technology provides an augmented reality display system for displaying a virtual object to be in focus when viewed by a user. In one embodiment, the focal region of the user is tracked, and a virtual object within the user focal region is displayed to appear in the focal region. As the user changes focus between virtual objects, they appear to naturally move in and out of focus as real objects in a physical environment would. The change of focus for the virtual object images is caused by changing a focal region of light processing elements in an optical path of a microdisplay assembly of the augmented reality display system. In some embodiments, a range of focal regions are swept through at a sweep rate by adjusting the elements in the optical path of the microdisplay assembly.Type: GrantFiled: February 12, 2016Date of Patent: March 7, 2017Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Avi Bar-Zeev, John Lewis

Patent number: 9588347Abstract: A device for generating a virtual light image. The device includes a real light source, a curved retroreflector surface, and a semi-transparent mirror. The retroreflector surface is situated so that the light of the real light source transmitted through the semi-transparent mirror does not reach the retroreflector surface. A shape of the retroreflector surface for a given visibility range, at least in a subregion of the area that is essential for the image in the visibility range, is determined by the fact that at each point of the subregion, the pair of a reflection angle A and an optical distance between this point of the subregion of the retroreflector surface and the virtual light image is Pareto-minimal, provided that the subregion of the retroreflector surface does not interrupt primary beams from the real light source to the semi-transparent mirror.Type: GrantFiled: June 5, 2013Date of Patent: March 7, 2017Inventors: Igor Nikitin, Martin Göbel, Gernot Heisenberg

Patent number: 9588350Abstract: According to an embodiment, an image display device includes an optical element, a voltage controller, and a display. Regarding the optical element, the refractive-index distribution changes according to the voltage applied thereto. The voltage controller controls, in a first mode, the voltage applied to the optical element in such a way that a first-type refractive-index distribution is achieved which acts as a first-type Fresnel lens; and controls, in a second mode that is different than the first mode, the voltage applied to the optical element in such a way that a second-type refractive-index distribution is achieved which acts as a second-type Fresnel lens having a greater number of steps than the first-type Fresnel lens. The display is disposed on the back side of the optical element and displays images.Type: GrantFiled: April 24, 2014Date of Patent: March 7, 2017Assignee: Kabushiki Kaisha ToshibaInventors: Ayako Takagi, Shinichi Uehara, Masako Kashiwagi, Masahiro Baba

Patent number: 9588355Abstract: A construction for eyeglasses provides a frame with a first rim for securing a first fixed lens, a second rim for securing a second fixed lens, a first temple hinge for pivotally joining a first temple arm to the first rim, a second temple hinge for pivotally joining a second temple arm to the second rim, and a pair of double-knuckle hinges for joining pivotally joining a first selectable lens and a second selectable lens to the frame. The double knuckle hinges allow the first selectable lens and the second selectable lens to rotate 270 degrees, switching between a storage configuration and an active configuration. In the active configuration the selectable lenses overlap the fixed lenses in order to provide additional desirable properties. Thus the selectable lenses can be used in combination with the fixed lenses to act as bifocal glasses.Type: GrantFiled: January 23, 2015Date of Patent: March 7, 2017Inventor: Steven Cohn
