The camera images can be captured automatically using a camera disposed within an augmented reality device worn by a user. The camera images can be processed automatically using a processor located within the augmented reality device. The virtual display images can be displayed automatically to the user within the augmented reality device while the user is looking through the augmented reality device and simultaneously viewing real objects through the augmented reality device. The virtual display images can be based on the processed camera images. Additional steps can include accepting a first user input, storing camera image(s) on a memory located within the augmented reality device based on the first input, accepting a second user input, and displaying stored image(s) to the user based on the second input. ## Claims ### Claim 1 A wearable augmented reality device comprising: a frame comprising a frame body; a first arm hingedly attached to the frame body; a second arm hingedly attached to the frame body; a camera positioned in a front portion of the frame body; a first processor positioned in the frame body; an optical display device positioned in a top portion of the frame body; a first lens optical element; a second lens optical element; a combiner prism optical element; wherein the first processor is configured to: project from the optical display device processed camera images towards the combiner prism optical element such that light emitted from the optical display device passes through a top portion of the second lens optical element and the combiner prism optical element and is projected from the second lens optical element back toward the combiner prism optical element, and then is reflected from a bottom portion of the combiner prism optical element towards a focused display position towards an eye of a wearer of the wearable augmented reality device. ### Claim 2 (depends on 1) The wearable augmented reality device of claim 1, wherein the first arm comprises a battery compartment in distal end of the first arm. ### Claim 3 (depends on 1) The wearable augmented reality device of claim 1, wherein the first arm is hingedly attached to the frame body at a degree of tilt ranging from 3-10 degrees. ### Claim 4 (depends on 1) The wearable augmented reality device of claim 1, wherein the combiner prism optical element has a spherical reflective surface. ### Claim 5 (depends on 1) The wearable augmented reality device of claim 1, wherein when the first arm and the second arm are in a folded position they are parallel to each other. ### Claim 6 (depends on 1) The wearable augmented reality device of claim 1, wherein the processor is further configured to move the focused display position by adjust a position of the image being projected from the optical display device. ### Claim 7 (depends on 1) The augmented reality device of claim 1 further comprising: a wearable control mechanism, comprising: a body having an curved shape; a second processor; a touch input surface; and an adjustable strap. ### Claim 8 (depends on 7) The augmented reality device of claim 7, wherein the wearable control mechanism is configured to be worn on a index finger and receive touch operations from a thumb. ### Claim 9 (depends on 7) The augmented reality device of claim 7, wherein the second processor is configured to receive an input from the touch input surface and wirelessly transmit a command to the first processor. ### Claim 10 (depends on 9) The augmented reality device of claim 9, wherein the first processor is further configured to: receive a command from the wearable control mechanism; and cause an adjustment to the operation of the optical display device. ### Claim 11 (depends on 9) The augmented reality device of claim 9, wherein the first processor is further configured to: receive a command from the wearable control mechanism; and cause an image to be taken by the camera. ### Claim 12 (depends on 1) The augmented reality device of claim 1, wherein the processed camera images comprise one or more virtual images. ### Claim 13 (depends on 1) The augmented reality device of claim 1, wherein the optical display device is a micro-OLED. ### Claim 14 (depends on 1) The augmented reality device of claim 1, further comprising: a rear housing element configured for attachment to a rear portion of the frame body. ### Claim 15 (depends on 1) The augmented reality device of claim 1, wherein the rear housing element comprises charging connectors. ### Claim 16 (depends on 1) The augmented reality device of claim 1, wherein the first processor is positioned in the frame body in an internal area adjacent to a nose bridge of the frame body. ### Claim 17 (depends on 16) The augmented reality device of claim 16, further comprising a reinforcement bracket positioned in the internal area, and a camera module holding the camera is affixed thereto. ### Claim 18 (depends on 1) The augmented reality device of claim 1, wherein the combiner prism optical element is positioned in the second lens optical element. ### Claim 19 (depends on 1) The augmented reality device of claim 1, wherein the first lens optical element is a solid optical lens without a combiner prism optical element. ### Claim 20 (depends on 1) The augmented reality device of claim 1, wherein the bottom portion of the combiner prism optical element has a coated and partially reflecting mirrored surface having the characteristics of a high reflection low incident angle and high transmission at high angles.
