     TECHNICAL FIELD 
     The present disclosure relates generally to electronic devices, and more particularly to wearable augmented reality devices. 
     BACKGROUND 
     Virtual reality systems and devices have become increasingly popular in recent years. Various video game arrangements, movie presentation systems, and other devices and systems can allow a user to view and sometimes even interact with a virtual reality world. For example, some sophisticated gaming systems allow a user to wear a headset that provides an entirely virtual environment to see and interact with. 
     Unfortunately, many virtual reality devices and systems can be unsafe when users are so immersed in a virtual world that they are unaware of their real life surroundings. Because many existing virtual reality devices and systems do not provide an ability to see what real things are there, users have been known to injure themselves or others when they are unable to perceive their real life environments. For those devices and systems that do allow some perception of an actual real life environment, there is typically little to no integration between real life items and virtual reality items. Furthermore, existing devices and systems often have no ability to adjust virtual reality displays and presentations based on the real life environment of a user. 
     Although traditional ways of providing a virtual or augmented reality for a user have worked well in the past, improvements are always helpful. In particular, what is desired are augmented reality devices and systems that integrate virtual displays and presentations with real life surroundings in a robust and safe manner, and that allow for customized adjustments to the virtual displays and presentations based on the environment of the user. 
     SUMMARY 
     It is an advantage of the present disclosure to provide augmented reality devices and methods for using them that integrate virtual displays and presentations with real life surroundings in a robust and safe manner, and that allow for customized adjustments to the virtual displays and presentations based on the environment of the user. The disclosed features, apparatuses, systems, and methods provide improved augmented reality solutions that involve virtual displays that enhance the experience of a user without impairing the ability of the user to perceive and act within their real life environment. These advantages can be accomplished in multiple ways, such as by providing an augmented reality device and system that readily couples to existing eyewear of a user, that provides virtual displays to the user in unique ways, and that records real life events around the user for customized playbacks on the virtual displays. 
     In various embodiments of the present disclosure, an augmented reality device can include an outer housing, an attachment component, a camera, and a display arrangement. The outer housing can have a front and a back that define parallel planes, are transparent, and are arranged to allow a user to see therethrough. The attachment component can be coupled to the outer housing and can be configured to removably attach the augmented reality device to eyewear of the user.

In some arrangements, the display arrangement can include a unibody optics enclosure, which can include an image emitting component, a unibody top prism, a unibody bottom prism, a combining optic component, and a projecting optic component. The unibody top prism can be bonded to the unibody bottom prism. At least one processor can be disposed within the unibody top prism and coupled to the camera and the display arrangement, and this at least one processor can be configured to receive camera images from the camera and provide the camera images to the display arrangement as at least a portion of the virtual display images. At least one memory device disposed within the unibody top prism and coupled to the at least one processor can be configured to store images captured by the camera. 
     In various further embodiments of the present disclosure, computer-implemented methods of operating an augmented reality device are provided. Pertinent process steps can include capturing camera images automatically using a camera disposed within an augmented reality device worn by a user, processing the camera images automatically using a processor located within the augmented reality device, and displaying virtual display images 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 virtual reality device. The virtual display images can be based on the processed camera images. 
     In detailed embodiments, the displaying step can include emitting the virtual display images from an image emitting component located within the augmented reality device, passing the virtual display images through a prism component located within the augmented reality device, and projecting the virtual display images through a projecting optic component located within the augmented reality device. Additional process steps can include accepting a first input from the user, storing one or more of the camera images on a memory located within the augmented reality device based on the first input, accepting a second input from the user, and displaying one or more of the stored images to the user based on the second input. 
     In still further embodiments of the present disclosure, an augmented reality system can include one or more non-transitory computer-readable media storing computer-executable instructions that, when executed on one or more processors, cause the one or more processors to perform operations on an associated augmented reality device. The operations can include at least capturing camera images automatically using a camera disposed within an augmented reality device worn by a user, processing the camera images automatically using a processor located within the augmented reality device, and displaying virtual display images 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 virtual reality device. The virtual display images can be based on the processed camera images. 
     In detailed embodiments, the augmented reality system can also include the augmented reality device.

     DETAILED DESCRIPTION 
     Exemplary applications of apparatuses, systems, and methods according to the present disclosure are described in this section. These examples are being provided solely to add context and aid in the understanding of the disclosure. It will thus be apparent to one skilled in the art that the present disclosure may be practiced without some or all of these specific details provided herein. In some instances, well known process steps have not been described in detail in order to avoid unnecessarily obscuring the present disclosure. Other applications are possible, such that the following examples should not be taken as limiting. In the following detailed description, references are made to the accompanying drawings, which form a part of the description and in which are shown, by way of illustration, specific embodiments of the present disclosure. Although these embodiments are described in sufficient detail to enable one skilled in the art to practice the disclosure, it is understood that these examples are not limiting, such that other embodiments may be used, and changes may be made without departing from the spirit and scope of the disclosure. 
     The present disclosure relates in various embodiments to features, apparatuses, systems, and methods for augmented reality devices. The disclosed embodiments can include augmented reality devices and methods for using them that integrate virtual displays and presentations with real life surroundings in a robust and safe manner, and that allow for customized adjustments to the virtual displays and presentations based on the environment of the user. In particular, the disclosed embodiments can utilize an augmented reality device that is wearable by a user and that preferably can be readily coupled to eyewear of the user. 
     Such an augmented reality device can be called a “monocle,” which can be a relatively small wearable device having a near-eye optical engine equipped with a camera and a display that are configured to capture visual data, process that data on the device, and display the resulting processed data as images and videos optically in front of the eye of the user while simultaneously transferring that data wirelessly off device. 
     In various detailed examples, which are merely illustrative and non-limiting in nature, the disclosed monocle can use one or more cameras and processors to monitor user surroundings, take images, and detect objects and depth information, as well as to provide zoom, pan, and tilt functionalities, language translation, health monitoring, and first and third person shooting, among other possible functions. Various detailed features can include storage of time stamped video on a circular buffer for display of a retroactive moment in time, high value zoom using an on-board camera to digitally capture a user perspective at a much higher resolution than the human eye, digital enhancement and optical display of captured images to the user using the digital display, a personal flashlight using on-device flash LEDs to project light out for a hands-free light word on face, and/or touch strip access around edges of the device for on-device control of user interface, among other possible features. 
     Although various embodiments disclosed herein discuss the provided augmented reality device as a monocle, it will be readily appreciated that the disclosed features, apparatuses, systems, and methods can similarly be used for any relevant device or system having multiple devices or views. For example, two monocles may be used in a given arrangement, with both monocles coupling to eyewear of a user to provide cameras and virtual images for each eye of the user. Other applications, arrangements, and extrapolations beyond the illustrated embodiments are also contemplated. It will be understood that reference herein to a monocle can also refer to such other devices and systems using other augmented reality device arrangements. 
     Referring first to  FIG.  1   , an example augmented reality device according to one embodiment of the present disclosure is illustrated in front elevation view. Augmented reality device (i.e., “monocle”)  100  can generally include a clip  110  or other coupling component, a camera  120 , and an outer housing  130 . Clip  110  can be used to couple monocle  100  to eyewear or another item worn by a user. Camera  120  can capture images of that which is being seen by the user. Outer housing  130  can be at least partially transparent, such that the user is able to look therethrough to see real life environments. 
     Continuing with  FIG.  2 A , the augmented reality device of  FIG.  1    is shown in front elevation view as being coupled to user eyewear. As shown, monocle  100  can be clipped over the front user eyewear  10  by way of clip  110 , such that the user can look through the eyewear (which is presumably transparent) and also the through monocle by way of transparent outer housing  130 .  FIG.  2 B  illustrates in front elevation view possible positioning of an augmented reality device relative to user eyewear. Again, clip  110  can be used to couple monocle  100  to user eyewear  10 . As a part of monocle  100 , clip  110  can allow the entire monocle to be positioned from side to side or up and down with respect to user eyewear  10  by simply sliding the entire monocle in the directions desired. In some arrangements, clip  110  can be over molded with a soft touch material, such as a thermoplastic elastomer, for example, which can securely couple monocle  100  to user eyewear  10  while preventing or limiting damage to the user eyewear. 
     Turning next to  FIGS.  3 A through  3 F  an example augmented reality device (i.e. monocle)  100  is shown in various views.  FIGS.  3 A and  3 B  depict monocle  100  in front perspective and rear perspective views respectively.  FIG.  3 C  shows monocle  100  in front perspective view showing internal components, while  FIG.  3 D  depicts the monocle in rear perspective view with the back outer housing removed.  FIGS.  3 E and  3 F  illustrate monocle  100  with the back outer housing removed and showing internal components in rear perspective and reverse rear perspective views respectively. As shown in these various views, monocle  100  can generally include several major components, which can include a unibody top prism  140 , a unibody bottom prism,  142 , an outer housing  130 , and a clip  110 . 
     Outer housing  130  can include at least an outer housing front  132 , an outer housing back  134 , and an outer housing side and top  136 , among other possible outer housing components. Outer housing front  132  and outer housing back  134  can define parallel planes, can be transparent or translucent, and can be arranged to allow a user to see therethrough, as will be readily appreciated. Outer housing  130  can also include a left side touch surface  137  on the left side of the monocle and a right side touch surface  138  on the right side of the monocle. Touch surfaces  137 ,  138  can be configured to accept user inputs, such as by a user touching or pressing on the touch surfaces. Alternatively, a button or other pushed component could be used in place of such touch surfaces  137 ,  138 . One or more touch sensor flex cables  139  can be configured to communicate user inputs from one or both touch surfaces  137 ,  138  to an onboard processor within monocle  100 . 
     Transitioning to  FIG.  4 A , a schematic diagram of a side view of a user looking through an example augmented reality device having a prism arrangement is provided. In various arrangements, the disclosed monocle or augmented reality device can have a unibody prism that can have two parts coupled together. Unibody top prism  140  can be bonded or otherwise coupled to unibody bottom prism  142 . Unibody top prism  140  can function both as a prism for device optics and a housing area for various internal electronic components, while unibody bottom prism  142  can function with unibody top prism  140  to provide virtual images for a user of the monocle in a unique manner. 
     The disclosed monocle or augmented reality device can use a reflective optical surface in conjunction with a folding prism to collect and project light from an optical display onto the retina of a user in a manner to provide a virtual display that is non-invasive with respect to being able to see real life objects in the environment of the user. 
     In various arrangements, the monocle can generally have two primary light paths with respect to the eye  1  of a user. A first light path  2  can be an optical display path for a virtual image. Light forming a virtual image can be projected into an optical prism  140 ,  142  from a micro-display or other optical display device  146  located within an upper housing  136  region downward past a combining optic  144 , which can be a 50/50 dielectric material, for example. The virtual image along first light path  2  can then be directed toward a projecting optic  148 , which can be spherical and have a reflective coating, such as an aluminum coating, for example. The virtual image along first light path  2  can then be collected at the projecting optic  148  and projected back up toward the combining optic  144  where the virtual image along first light path  2  is then redirected toward the user eye  1 , where it can enter the user pupil and be focused on the user retina, as shown. 
     A second light path  3  can be a “see-through” or real object view path, which can be generated from the real life environment of the user. Second light path  3  can pass directly through the front and back flat surfaces of the optical prism  140 ,  142  unimpeded for a real object view to enter into the user eye and be focused on the user retina. In various embodiments, the virtual image display can be projected along first light path  2  at a downward angle slightly below the normal forward glancing vision of the user such that the virtual image display does not impede the normal vision of the user viewing real objects along second light path  3 . As will be readily appreciated, the overall field of view of the user can have an upper bound or limit  4  and a lower bound or limit  5 , and both the first light path  2  and the second light path  3  can fall within this overall field of view of the user. 
       FIG.  4 B  illustrates a schematic diagram of light paths present in the augmented reality device of  FIG.  4 A  according to one embodiment of the present disclosure. Again, light  6  can be projected from an optical display  146 , past combining optic  144 , reflected off projecting optic  148  back to the combining optic, where it is then combined and directed toward user  1  as a virtual image  6 . Various adjustments to the optical display  146 , combining optic  144 , projecting optic  148 , and/or other optics components can be made to focus the final image for the user  1  in a customized manner, as will be readily appreciated. 
     Continuing with  FIGS.  5 A and  5 B  an example augmented reality device with its back outer housing removed is illustrated in front perspective and partially exploded view and rear perspective and partially exploded view respectively. Again, monocle  100  can include a unibody top prism  140  and a unibody bottom prism  142  which can be bonded together in the finished monocle. A beam splitter  145  can be located along the top of unibody bottom prism  142  to split the projected light image before it is then combined by the combining optic. A reflection mirror  147  can be located along the bottom of unibody bottom prism  142  to reflect the projected light image back to the combining optic. 
       FIG.  6    illustrates in fully exploded view the augmented reality device of  FIG.  5 A . As shown, monocle  100  can include a unibody top prism  140 , a unibody bottom prism  142 , an optical display device  146 , a camera  120 , a printed circuit board assembly  150 , an outer housing back  134 , and a clip  110 , among various other components. One or more fasteners  102 , which can be screws, for example, can fasten components together, such as through openings in outer housing back  134  and into mounting points  104  within unibody top prism  140 . Again, unibody top prism  140  can house various electronic components, such as optical display device  146 , camera  120 , and printed circuit board assembly  150 , which can include one or more processors and other electronic components. Optical display device  146  can be a micro-OLED, for example, although other types of display devices can be used. 
     Moving next to  FIGS.  7 A- 7 F , an example charging case for an augmented reality device is shown in various views.  FIGS.  7 A and  7 B  depict charging case  200  in front perspective and rear perspective views respectively.  FIGS.  7 C and  7 D  illustrate charging case  200  with an augmented reality device  100  docked therein in rear perspective and alternative rear perspective views respectively.  FIGS.  7 E and  7 F  show charging case  200  in a closed position in front perspective and rear perspective views respectively. 
     Charging case  200  can have a lid  202  and a base  204 , which can be coupled by way of a hinge  206  or other suitable coupling arrangement. Base  204  can carry a tray  208 , which tray can be sized and shaped to contain a monocle or other augmented reality device therein. Lid  202 , base  204 , and tray  208  can be formed from molded plastic material, for example, although other types of materials can be used. In various arrangements, lid  202  can be connected to base  204  and tray  208  by way of pins, which can be formed from steel, for example. 
     One or more pogo pins  210  or other suitable electrical connectors can be located within base  204 , and these pogo pins can be configured to electrically couple to a monocle docked within charging case  200  in order to charge the monocle. A magnet  212  located on lid  202  can facilitate locking the case closed when the lid is placed against base  204 . A top silicone sticker  214  or another soft component can be located on an under side of lid  202 , while a bottom silicone sticker  216  or another soft component can be located within tray  208 . These silicone stickers  214 ,  216  or other soft components can function to protect a docked monocle from scratches or other damage. 
     A communications port  218  can be located on an outer surface of base  204  and can facilitate communications with an outside device. For example, an outside computer, phone, tablet or other device can be coupled to communications port  218  in order to communicate with a monocle or other augmented reality device docked within charging case  200 . Communications port  218  can be a USB-C port, for example, although other types of ports can also be used. Charging case  200  can also include a battery, such as a lithium-ion rechargeable battery, for example, although other types of batteries may also be used. The battery can charge a docked monocle or other augmented reality device by way of pogo pins  210 . In some arrangements, the monocle or other augmented reality device can be held in place by magnets when docked. 
     In some arrangements, charging case  200  can function simply as a battery, such as to recharge a docked monocle or other augmented reality device. In other arrangements, charging case  200  can be more active and provide additional functions. For example, charging case  200  can be configured to receive images stored on a docked monocle and store them to a separate memory, such as an SD card. Charging case  200  can also be plugged into a computer, smart phone, or other computing device by way of communications port  218 , such that images can be taken from a docked monocle and stored to the other computing device. 
     In various arrangements, charging case  200  may also be configured to accept user inputs, such as through one or more buttons, touchpads, IMU or other haptic feedback sensors, and/or other types of user input components. Wireless communications with outside devices may also be possible and wired connections may transfer data as well as provide power, such that extended operation of the charging case and docked monocle may be possible. 
     Transitioning next to  FIG.  8   , a schematic diagram is provided of an example electronic system having an augmented reality device. Electronic system  300  can include various components related to monocle  100 . A primary system-on-module  302  can include a system-on-chip  304  having various communications connections to different system components. Such communications connections can include various wireless connections, such as, for example, Bluetooth and Wifi, as well as various wired connections, such as, for example, USB, MIPI, and the like. Different system components can include monocle  100 , one or more outside processors  310 , one or more outside computers  312 , one or more other cameras  314 , one or more outside storage devices  316 , which can be used to store various buffer clips, and one or more outside input devices  318 , among other possible components. 
       FIG.  9 A  illustrates a schematic diagram of an example traffic manager and software module arrangement of an electronic system having an augmented reality device. Arrangement  400  can include a traffic manager  402 , which can receive inputs from a variety of devices and provide outputs to one or more devices, such as an OLED display  404 . OLED display can correspond to optical display device  146  on monocle  100  above. A built in speaker (not shown) may also provide audio outputs in some arrangements. Inputs can include, for example, those coming from an inertial measurement unit (“IMU”)  406 , a microphone  408 , and/or a camera  410  (which can correspond to camera  120  above), among other possible inputs. 
     Traffic manager  402  can be located on the monocle or other augmented reality device, so as to minimize data transfer issues. As such, a compression module  412  feeding images, video and/or other data to traffic manager  402  and a decompression module  414  receiving images, video, and/or data from the traffic manager can also be located on the monocle itself. Traffic manager  402  can be in communication with a wireless communications module  416 , which can be Bluetooth Low Energy (“BLE”) enabled, for example. Wireless communications module  416  can also have its own processor, touch controller, and/or BLE antenna in some arrangements. One or more memory units  418 , such as a UFS NAND flash memory can be coupled to traffic manager  402 , and such memory units can also be located on the monocle device itself. 
       FIG.  9 B  illustrates a schematic diagram of an example communications arrangement for an electronic system having an augmented reality device. Communications arrangement  500  can involve one or more inputs, such as images captured by a camera  502  and/or sound captured by a microphone  504 , one or both of which can be located on a monocle or other augmented reality device. Such input(s) can be provided directly to a display  506  and/or speaker on the monocle for viewing and listening by a user  508 . In addition, such input(s) can also be provided to one or more outside devices  510 , such as a smart phone, computer, or the like. Transmission can be by way of an ISP  512  or other communications provider. Such input(s) can also be stored in one or more memory devices  514 . All or any combination of these input provisions can take place simultaneously for the same input(s), and a decompressor  516  can be used for such input(s) as may be necessary. 
     In addition to the foregoing details, the disclosed monocle or other augmented reality device can have various other features. Where wired connections are used, a USB connection can facilitate communication with another device, such as another body worn device, for example, for power and/or data transfer. In addition to providing stored images and/or audio captured by the monocle, the monocle display can also show live video from the monocle camera, as well as video and/or audio from other sources. In addition, the display can include annotations or other indicators with respect to real life objects in the actual field of view. 
     In various arrangements, the monocle can have zoom, pan, and tilt features using the onboard camera, such that magnified real view images can be presented to the user, and these functions can be performed digitally and/or in analog. The monocle can also take single higher resolution pictures that are stored to local memory. 
     While ordinary buttons can be used, a touch sensitive user interface surface can also be used for tapping or sliding motions. For example, a slide motion along a touch sensitive user interface can be used to advance or rewinds a given image playback. Speed of slide motion can also affect the speed of advance or rewind on a given buffer clip. An onboard accelerometer or IMU can also be used as a user interface by capturing head movements or other user movements, and an onboard microphone can capture audio from the user and/or the user environment. The microphone and IMU may be used either in isolation or together to implement a tap-based gesture interface 
       FIG.  10 A  illustrates a schematic diagram of an example buffer sequence for an augmented reality device. In various embodiments, the disclosed monocle can capture visual images and/or audio and save those visual images and/or audio as media clips to one or more buffers stored on the monocle itself. The monocle can write and rewrite a constant circular replay buffer of video for a set amount of time, such as, for example 30 seconds. This process can be performed continuously and can take place automatically or at the command of the user. In some arrangements, the user can provide one or more inputs that instruct the monocle to save a particular buffer segment without rewriting over that buffer segment. Saved buffer segments can then be replayed on demand. Such demand can be made by way of one or more user inputs, such as, for example, a button push, use of an onboard IMU or touch sensitive interface, or a user gesture or voice command, as well as through an outside device, such as a smart phone, smart watch, computer, or the like. Each buffer can be stored temporarily or permanently on the monocle and can also be offloaded to an outside device. 
     Multiple buffers can be used to store various events. As shown in buffer sequence  1000 , for example, a rotating sequence of four separate rewritable 30 second buffers can be used to temporarily store visual and/or audio data in real time as the user wears the monocle. If the user desires a particular sequence to be preserved, then a command can be given to store one or more buffer sequences to a kept memory location. If no such command is given, then each rewritable buffer can be written over with new data. Of course, more or fewer than four buffer segments can be used, and time lengths longer or shorter than 30 seconds can also be used. Captured images and/or audio can be streamed to the user as soon as may be practical, depending on remaining battery capacity and/or other operational factors. 
       FIG.  10 B  illustrates a schematic diagram of an example buffer management arrangement for an electronic system having an augmented reality device. Arrangement  1050  can include an arbiter or other processing component or module that controls the capturing and storing of visual image and/or audio inputs into different buffer segments. These buffer segments can be provided to an onboard monocle display, can be provided to an onboard monocle storage, or both. The arbiter can also control the rewriting of new material onto buffer segments, which can be rotated and overwritten. 
       FIG.  11    illustrates a schematic diagram of an example gesture state processing arrangement for an augmented reality device. Gesture state processing arrangement  1100  can include considerations for gesture states for a first input device (e.g., a button or touch surface) such as idle  1102 , triggered  1104 , pressed short  1106 , and pressed long  1108 . A certain amount of time, such as five seconds, for example, can separate each of these gesture states for the first input device. Gesture states for a second input device (e.g., a second touch surface) can include tapped  1110 , both pressed  1112 , and both pressed long  1114 . An initial gesture state  1116  can involve whether either button or touch surface has been pressed or touched, upon which a gesture state inquiry  1118  can determine which button or touch surface has been pressed or touched. In various arrangements involving touch surfaces, a slid gesture state  1120  can also be used. A compare actuated buttons/touch surfaces gesture state  1122  may also be implemented. 
       FIG.  12    illustrates a schematic diagram of an example state machine arrangement for an augmented reality device. The disclosed monocle can be a state device, and state machine arrangement  1200  can reflect various possible states for the monocle. An early initiation state  1202  can involve ultra-low device power situations, such as in the case of a low battery, which can then result in a powered down state  1204 . A full initiation state  1206  can involve low device power situations, which can cause transfer  1208  of vital data or assets and result in a shutdown pending state  1210 . Normal powered conditions can involve fully active device states within the realms of recording and capturing. Recording states can include a Record_D 0  (home state) state  1212  and a Record_D 1  state  1214 . Capturing states can include a Photo_D 0  state  1216  and a Photo_D 1  state  1218 . Capturing states can also include a Replay_D 0  state  1220  and a Replay_D 1  state  1222 . 
     Various example methods of operation for an augmented reality device will now be provided. It will be understood that the methods provided here are examples for purposes of illustration, and that many variations and other methods of use are also possible for the disclosed augmented reality devices and systems. 
       FIG.  13    illustrates a flowchart of an example method of operating an augmented reality device. In various embodiments, method  1300  can be applied using the various systems, devices, and features provided above. Some or all of the steps of method  1300  can be automatically performed, such that the entire method can be considered a computer-implemented method in some arrangements. 
     After a start step  1302 , a first process step can involve capturing camera images on the monocle or other augmented reality device. As noted above, this can be accomplished using a camera that is located on or within the monocle itself. Capturing images on the monocle can take place automatically, as a result of one or more user inputs, or both. 
     At a following process step  1306 , the captured camera images can be processed using a processor on the monocle or other augmented reality device. Such a processor can be located within an outer housing of the monocle, such as within a unibody top prism region. Camera image processing can involve altering the images, organizing the images, such as into buffer segments, and/or storing the images, among other possible image processing functions. 
     At the next process step  1308 , virtual images can be displayed to a user on the monocle or other augmented reality device based on the processed camera images. Displaying the virtual images can involve projecting the processed camera images through an optical system located within the monocle, as detailed above. Again, the display of virtual images can be done in a manner that does not impede the ability of the user to view the real life user environment. For example, the virtual image display can be along a light path that is separate from a straight ahead real life view path, such as downward from the straight ahead view path or in another direction within the peripheral view of the user. The method then ends at end step  1310 . 
     It will be appreciated that the foregoing method  1300  may include additional steps not shown, and that not all steps are necessary in some embodiments. For example, additional steps may include providing the monocle or other augmented reality device, communicating with one or more outside electronic devices, or stopping the display of virtual images. Other process steps can involve focusing the virtual images in a customized manner for the user or speeding up or slowing down the display of virtual images, among other possible actions. Furthermore, the order of steps may be altered as desired, and one or more steps may be performed simultaneously. For example, process steps  1304 - 1308  can all be performed simultaneously, which may take place on the same or different images. 
     Next,  FIG.  14    illustrates a flowchart of an example method of displaying virtual display images on an augmented reality device. In various embodiments, method  1400  can be applied using the various systems, devices, and features provided above. Some or all of the steps of method  1400  can be automatically performed, such that the entire method can be considered a computer-implemented method in some arrangements. In various embodiments, all of method  1400  can be considered a detailed process of step  1308  in method  1300  above. 
     After a start step  1402 , a first process step  1404  can involve emitting virtual images from an image emitting component located on the monocle or other augmented reality device. Again, this can be a micro-display or other optical display device located within an upper housing region of the monocle. In some arrangements, the virtual images can be emitted downward from the image emitting component to other optical components within the monocle. 
     At the next process step  1406 , the virtual images can be passed through a prism component located on the monocle or other augmented reality device. As noted above, such a prism component can be a folding prism having a top prism component and a bottom prism component bonded together to form a unibody prism. 
     At a following process step  1408 , the virtual images can be projected through a projecting optic component located on the monocle or other augmented reality device. Again, such a projecting optic can be spherical and can have a reflective coating, such as an aluminum coating, for example. The method then ends at end step  1410 . 
     It will be appreciated that the foregoing method  1400  may include additional steps not shown, and that not all steps are necessary in some embodiments. For example, additional steps may include passing the virtual images past a combining optic on a first pass, and then collecting the images at the combining optic after they have been projected through the projecting optic. The virtual images can then be redirected from the combining optic to the eye of the user. The order of steps may be altered as desired, and one or more steps may be performed simultaneously. For example, process steps  1404 - 1408  can all be performed simultaneously during a continuous displaying of virtual images. 
     Finally,  FIG.  15    illustrates a flowchart of an example method of operating an augmented reality device based on user inputs. In various embodiments, method  1500  can be applied using the various systems, devices, and features provided above. Some or all of the steps of method  1500  can be automatically performed, such that the entire method can be considered a computer-implemented method in some arrangements. In various embodiments, method  1500  can be considered in addition to method  1300  or method  1400  above, and it will be readily appreciated that some processes may include all steps from all of methods  1300 ,  1400 , and  1500 . 
     After a start step  1502 , a first process step  1504  can involve accepting a first input from a user of the monocle or other augmented reality device. Such a first user input can be any of a variety of inputs. Possible user inputs can include, for example, a button push on the monocle, a voice command, a gesture, user motion (which may be detected by an internal accelerometer), and/or various possible inputs on an outside device in communication with the monocle, such as a computer, smart phone, smart watch, charging case, or the like. Other user inputs are also possible. 
     At a following process step  1506 , one or more camera images can be stored in a memory located on the monocle or other augmented reality device based on the first user input. Such camera images can be organized and stored in one or more buffers in the onboard memory. In some arrangements, additional camera image storage can take place in one or more memory devices located outside the monocle as well. Such additional storage can involve the same camera images stored in the onboard memory, different camera images, or both. 
     At the next process step  1508 , a second input can be accepted from the user. Again, such a second user input can be any of a variety of user inputs, as listed above for process step  1504 . Second user input can be the same type of user input for the first user input, or it can be a different type of user input. For example, the first user input can be a voice command and the second user input can be a button push on the monocle. Other combinations of user inputs are also possible, and it is contemplated that all such combinations may be used. 
     At subsequent process step  1510 , the one or more stored images can be displayed to the user on the monocle or other augmented reality device based on the second user input. The displayed images can be provided by way of the optical arrangement detailed above, and the user can view the displayed images by looking toward them. For example, the displayed images can be shown within the monocle at an angle that is slightly below a straight ahead viewing angle, such that the user can simply look downward within the monocle to see the displayed images. The method then ends at end step  1512 . 
     Similar to foregoing methods  1300  and  1400 , it will be appreciated that method  1500  may include additional steps not shown, and that not all steps are necessary in some embodiments. For example, additional steps may include accepting a third user input that affects the manner in which the displayed images are provided. Such a third user input might control the zoom level, display angle, playback speed, and/or other aspects of the displayed images. The order of steps may be altered as desired, and one or more steps may be performed simultaneously. For example, process steps  1506  and  1510  can be performed simultaneously during a continuous process of storing and displaying various images. 
     Although the foregoing disclosure has been described in detail by way of illustration and example for purposes of clarity and understanding, it will be recognized that the above described disclosure may be embodied in numerous other specific variations and embodiments without departing from the spirit or essential characteristics of the disclosure. Certain changes and modifications may be practiced, and it is understood that the disclosure is not to be limited by the foregoing details, but rather is to be defined by the scope of the appended claims.
