A lens assembly within the main body includes a first lens configured to focus vision of a wearer on a first area of a display of the mobile computing device when the mobile computing device is secured to the main body. A first contact point disposed in a fixed position relative to the first lens is configured to contact a surface of the display when the mobile computing device is secured to the main body. The first contact point is detectable by the mobile computing device and usable by the mobile computing device to derive a position of the display relative to the at least one lens. ## Claims ### Claim 1 A head mounted display system for use with a mobile computing device, comprising: a main body configured to be worn on a human head; a lens assembly within the main body comprising a first lens configured to focus vision of a wearer on a first area of a display of the mobile computing device when the mobile computing device is secured to the main body; and a first contact point disposed in a fixed position relative to the first lens and configured to contact a surface of the display when the mobile computing device is secured to the main body, a location at which the first contact point contacts the surface of the display detectable by the mobile computing device and usable by the mobile computing device to derive a position of the display relative to the first lens. ### Claim 2 (depends on 1) The head mounted display system of claim 1 wherein the first contact point is brought into contact with the surface of the display in response to securing the mobile computing device to the main body. ### Claim 3 (depends on 2) The head mounted display system of claim 2 wherein the mobile computing device is secured to the main body by insertion of the mobile computing device into a retention pocket. ### Claim 4 (depends on 1) The head mounted display system of claim 1, wherein the first contact point comprises a stylus having a length sufficient for a stylus tip to contact the surface of the display. ### Claim 5 (depends on 4) The head mounted display system of claim 4, wherein the stylus tip is movable and is retracted from the display until a user presses a button which advances the stylus tip into contact with the surface of the display. ### Claim 6 (depends on 1) The head mounted display system of claim 1, wherein the lens assembly further comprises: a second lens configured to focus vision of the wearer on a second area of the display when the mobile computing device is secured to the main body. ### Claim 7 (depends on 6) The head mounted display system of claim 6, wherein the second lens is disposed in a fixed position relative to the first lens and the first contact point. ### Claim 8 (depends on 6) The head mounted display system of claim 6, wherein the second lens is movable relative to the first lens and the first contact point, and the head mounted display system further comprises a second contact point disposed in a fixed position relative to the second lens and configured to contact the surface of the display when the mobile computing device is secured to the main body, a location at which the second contact point contacts the surface of the display detectable by the mobile computing device. ### Claim 9 (depends on 1) The head mounted display system of claim 1, further comprising: a button accessible to a user's finger external to the main body; and a conductive path from the button to the first contact point. ### Claim 10 A head mounted display system, comprising: a main body configured to be worn on a human head; a mobile computing device including a display secured to the main body; a lens assembly within the main body comprising a first lens configured to focus vision of a wearer on a first area of the display; and a first contact point disposed in a fixed position relative to the first lens and contacting a surface of the display, wherein the mobile computing device detects a location where the first contact point contacts the surface of the display to determine a position of the display relative to the first lens. ### Claim 11 (depends on 10) The head mounted display system of claim 10 wherein the mobile computing device controls a position of data displayed on the display based upon the position of the display relative to the at least one lens. ### Claim 12 (depends on 10) The head mounted display system of claim 10 wherein the mobile computing device derives horizontal and vertical positions of the first lens relative to the display based upon the location at which the first contact point contacts the surface of the display. ### Claim 13 (depends on 10) The head mounted display system of claim 10 wherein the first contact point is brought into contact with the surface of the display in response to securing the mobile computing device to the main body. ### Claim 14 (depends on 13) The head mounted display system of claim 13 wherein the mobile computing device is secured to the main body by insertion of the mobile computing device into a retention pocket. ### Claim 15 (depends on 10) The head mounted display system of claim 10, wherein the first contact point comprises a stylus having a length sufficient for a stylus tip to contact the surface of the display. ### Claim 16 (depends on 15) The head mounted display system of claim 15, wherein the stylus tip is movable and is retracted from the display until a user presses a button which advances the stylus tip into contact with the surface of the display. ### Claim 17 (depends on 10) The head mounted display system of claim 10, wherein the lens assembly further comprises: a second lens configured to focus vision of the wearer on a second area of the display. ### Claim 18 (depends on 17) The head mounted display system of claim 17, wherein the second lens is disposed in a fixed position relative to the first lens and the first contact point. ### Claim 19 (depends on 17) The head mounted display system of claim 17, wherein the second lens is movable relative to the first lens and the first contact point, and the head mounted display system further comprises a second contact point disposed in a fixed position relative to the second lens and configured to contact the surface of the display, a location at which the second contact point contacts the surface of the display detectable by the mobile computing device. ### Claim 20 (depends on 19) The head mounted display system of claim 19 wherein the mobile computing device derives an interpupillary distance based upon locations at which the first contact point and the second contact point contact the surface of the display. ### Claim 21 (depends on 10) The head mounted display system of claim 10, further comprising: a button accessible to a user's finger external to the main body; and a conductive path from the button to the first contact point. ### Claim 22 A head mounted display system for use with a mobile computing device, comprising: a main body configured to be worn on a human head; a lens assembly within the main body comprising a set of lenses configured to focus vision of a wearer on respective areas of a display of the mobile computing device when the mobile computing device is secured to the main body; and a contact point disposed in a fixed position relative to each of the set of lenses and configured to contact a surface of the display when the mobile computing device is secured to the main body, a location at which the contact point contacts the surface of the display detectable by the mobile computing device and usable by the mobile computing device to derive a position of the display relative to the set of lenses; wherein the position is usable by a mobile computing device to adjust a position of an image displayed on the display.
