Head Mounted Display With Lens

Abstract

A head mounted display device that displays three dimensional images from a mobile device, which includes a viewing assembly, a housing, a mobile device holder, connected to the housing, a reflecting surface, connected to the housing that reflects images displayed by the mobile device, a lens, and an eyepiece onto which the reflecting surface reflects the images through the lens.

What is claimed is: 
     
         1 . A head mounted display device for displaying images from a mobile device, comprising:
 a housing that secures an inserted mobile device, which fits on the head of a human viewer, the mobile device comprising a forward-facing side with a display;   a reflecting surface, connected to the housing, that reflects images displayed by the mobile device display;   one or more lenses, connected to the housing, that focuses the images reflected by the reflecting surface, and   an eyepiece, connected to the housing, that reflects the images from the one or more lenses into the eye of the viewer.   
     
     
         2 . The device of  claim 1  wherein the one or more lenses consist of two lenses, a right lens and a left lens. 
     
     
         3 . The device of  claim 2 , wherein each of the two lenses is a Fresnel lens. 
     
     
         4 . The device of  claim 1 , wherein the housing fits a mobile device with a display of at least four diagonal inches. 
     
     
         5 . The device of  claim 1 , wherein the reflecting surface is sufficiently large to reflect substantially all of the light emanating from the mobile device display. 
     
     
         6 . The device of  claim 1 , wherein said mobile device displays a first image on its right side and a second image on its left side and wherein said reflecting surface comprises a right mirror that reflects the first and a left mirror that reflects the second image. 
     
     
         7 . The device of  claim 6 , wherein said housing further comprises an opaque optical block that prevents the first image from crossing over to the left mirror and prevents the second image from crossing over to the right mirror. 
     
     
         8 . The device of  claim 1 , wherein the eyepiece comprises two separate elements. 
     
     
         9 . The device of  claim 1 , wherein the eyepiece comprises a single element. 
     
     
         10 . The device of  claim 1 , wherein the eyepiece is half-silvered. 
     
     
         11 . The device of  claim 1 , wherein the focal length from the lens to the eyepiece is between 75 and 150 millimeters. 
     
     
         12 . The device of  claim 1 , wherein the lower extent of the housing rests at least 10 millimeters above the eyebrow of the viewer when the housing is fitted to the head of the viewer. 
     
     
         13 . The device of  claim 1 , wherein when fit against the head of the viewer the mobile device, lens, and reflecting surface are positioned by the housing above the eyebrow of the viewer. 
     
     
         14 . The device of  claim 1 , wherein the optical distance from the display to the lens is approximately equal to the optical distance from the lens to the eye. 
     
     
         15 . The device of  claim 1 , wherein the mobile device is secured in a substantially vertical position by the housing, the lens is secured in a substantially horizontal position, and the reflecting surface forms the hypotenuse of a triangle formed by the plane of the mobile device and the plane of the lens. 
     
     
         16 . The device of  claim 1 , wherein the mobile device is secured in a substantially vertical position by the housing, such that its display faces away from the viewer. 
     
     
         17 . The device of  claim 1 , wherein the mobile device is secured in a substantially horizontal position by the housing, such that its display faces downwards, towards the eyepiece.
