First cartridge can hold the display such that when the first cartridge is coupled to the portion of the frame and holding the display, the display is oriented to face away from the frame at a selected angle. They cover structure is provided that removably attaches to a portion of either the frame or the first cartridge. A visor removably attaches to the cover structure and is disposed such that a surface of the visor reflects an image displayed on the display back toward the frame. ## Claims ### Claim 1 A head mounted apparatus comprising: a frame; a band structure removably coupled to the frame; a first cartridge removably coupled to a portion of the frame, the first cartridge configured to hold a display, wherein when the first cartridge is coupled to the portion of the frame and is holding the display, the display is oriented to face away from the frame at a selected angle; a cover structure removably attached to a portion of at least one of the frame and the first cartridge; and a visor removably attached to the cover structure and disposed such that a surface of the visor reflects an image displayed on the display. ### Claim 2 (depends on 1) The head mounted apparatus of claim 1, wherein the display comprises a first mobile device and the first cartridge comprises a first recess to removably couple to the first mobile device. ### Claim 3 (depends on 1) The head mounted apparatus of claim 1, further comprising a second cartridge configured to removably couple to the portion of the frame in place of the first cartridge, the second cartridge comprises a second recess to removably couple to a second mobile device, wherein the second recess and the second mobile device are each different sizes than the first recess and the first mobile device. ### Claim 4 (depends on 2) The head mounted apparatus of claim 2, wherein the first cartridge comprises an identifier readable by the first mobile device. ### Claim 5 (depends on 2) The head mounted apparatus of claim 2, wherein at least one of the cover structure and the cartridge comprises a mirror mechanism positioned to reflect eye movements of a wearer toward a camera of the mobile device. ### Claim 6 (depends on 1) The head mounted apparatus of claim 1, wherein the cover structure comprises at least one of a camera mount or a camera. ### Claim 7 (depends on 6) The head mounted apparatus of claim 6, wherein the camera mount comprises an electronic input-output interface for electronically coupling the camera to one of the display or a mobile device coupled to the display. ### Claim 8 (depends on 1) The head mounted apparatus of claim 1, wherein the surface of the visor comprises at least one transparent lens and the surface reflects the image displayed on the display toward the frame. ### Claim 9 (depends on 2) The head mounted apparatus of claim 2, wherein the first cartridge further comprises a bottom surface and sidewalls, the sidewalls being about at least a portion of the perimeter of the first recess. ### Claim 10 (depends on 1) The head mounted apparatus of claim 1, wherein the frame comprises at least one of a bracket and a clip that engage the first cartridge when the first cartridge is removably coupled to the portion of the frame. ### Claim 11 A method comprising: providing a frame; providing a band structure removably coupled to the frame; removably coupling a first cartridge to a portion of the frame, the first cartridge configured to hold a display, wherein when the first cartridge is coupled to the portion of the frame and holding the display, the display is oriented to face away from the frame at a selected angle; providing a cover structure removably attached to a portion of at least one of the frame and the first cartridge; and providing a visor removably attached to the cover structure and disposed such that a surface of the visor reflects an image displayed on the display. ### Claim 12 (depends on 11) The method of claim 11, wherein the display comprises a first mobile device and the first cartridge comprises a first recess to removably couple the first mobile device. ### Claim 13 (depends on 11) The method of claim 11, further comprising providing a second cartridge configured to removably couple to the portion of the frame in place of the first cartridge, the second cartridge comprises a second recess to removably couple to a second mobile device, wherein the second recess and the second mobile device are each different sizes than the first recess and the first mobile device. ### Claim 14 (depends on 12) The method of claim 12, wherein the first cartridge comprises an identifier readable by the first mobile device. ### Claim 15 (depends on 12) The method of claim 12, further comprising providing a mirror mechanism on at least one of the cover structure and the first cartridge, the mirror structure positioned to reflect eye movements of a wearer toward a camera of the first mobile device. ### Claim 16 (depends on 11) The method of claim 11, further comprising providing at least one of a camera mount or a camera on the cover structure. ### Claim 17 (depends on 16) The method of claim 16, wherein the camera mount comprises an electronic input-output interface for electronically coupling the camera to one of the display or a mobile device coupled to the display. ### Claim 18 (depends on 11) The method of claim 11 wherein the surface of the visor comprises at least one transparent lens and further comprising reflecting, by the surface, the image displayed on the display toward the frame. ### Claim 19 (depends on 1) The method of claim 1, wherein the first cartridge further comprises a bottom surface and sidewalls, the sidewalls being about at least a portion of the perimeter of the first recess. ### Claim 20 (depends on 1) The method of claim 1, wherein the frame comprises at least one of a bracket and a clip that engage the first cartridge when the first cartridge is removably coupled to the portion of the frame.
