     A smart device may be used to provide a camera for an otoscope. The smart device may be a smart phone, a smart tablet (e.g., an iPad), a computer, and/or the like. The smart device may include a camera, which may be used by the otoscope to take an image and/or a video. The camera on the smart phone may provide a cost-effective method of providing the otoscope with the camera. For example, smart phones may now be widely available, and users may already have access to one. By providing a user with a device, such as an otoscope clip device, to attach an otoscope to the smart phone, the user may be given the ability to use the otoscope to take a video which may then be sent to a medical professional. 
     When attaching an otoscope to a smart phone with the otoscope clip, the user may wish to align the otoscope with the camera on the smart phone. Aligning the otoscope with the smart phone camera may provide an image that may not be impeded by a component of the otoscope. Aligning the otoscope with the smart phone camera may help keep stray light out of the image (e.g., seal light out of the otoscope) to improve an image quality. To align the otoscope with the camera on the smart phone, a user may have to flip the phone back and forth as the smart phone camera may be on the opposite side of the display. 
     To minimize flipping the phone back and forth during a camera alignment, an overlay or image may be projected and/or displayed onto the screen of the smart phone. The overlay may be referred to as an alignment image. The alignment image may be complementary to an alignment feature, such as an alignment tab, on the otoscope clip such that a user may align the alignment image with the alignment tab. The alignment image may be complementary to at least a portion of the otoscope clip (e.g., at least a portion of an alignment feature, an alignment tab, and/or the like) such that a user may align the alignment image with the alignment tab. When the alignment image is aligned with the alignment tab, the viewing portion of the otoscope may be aligned with the smart phone camera. Aligning the alignment image with the alignment tab may also allow the user to align the otoscope with the smart phone camera while minimizing turning the phone back and forth during the alignment. 
     The alignment image may encourage the user to correctly attach the otoscope to the smart phone using the otoscope clip device. For example, the alignment image may be placed at the top of the smart phone to encourage the user to attach the otoscope. For example, the alignment image may be placed at a position on the smart phone to encourage the user to place the otoscope clip over the top of the smart phone. For example, the alignment image may be displayed in such a way to encourage the user to attach the otoscope clip so that the otoscope clip may not impede one or more buttons of the smart phone when the otoscope clip is attached to the smart phone. 
     The otoscope clip device may be designed to provide better ergonomics for a user. For example, the otoscope clip device may be designed to improve how a user may be holding a smart device. The otoscope clip may be designed to avoid impeding the ability of the user to place the otoscope in an ear of a patient. The otoscope clip may be designed to encourage a user to correctly place the otoscope in an ear of the patient. For example, the clip may be designed to allow a user to rest their hand against a head of a patient while using the otoscope attached to the smart phone via the otoscope clip. 
     The otoscope clip may be designed to provide a secure method of attachment to the smart device and may be designed to be attached to a number of different styles of smart phones. The otoscope clip may comprise a clamp assembly that may be used to secure the otoscope clip to the smart phone. The clamp assembly may assist in minimizing the movement of the otoscope during the process of taking an image. For example, the clamp assembly may minimize movement of the clip along an axis of a surface of the smart phone to improve the ability of a user to align the viewing portion of the otoscope with the camera of the smart phone. 
     The otoscope clip may be designed to avoid compressing one or more buttons of the smart phone. The otoscope clip may be designed to prevent a user from accidentally pressing one or more buttons of the smart phone. For example, the clip may avoid compressing the on/off switch, may avoid compressing a volume switch, may prevent a user from pressing the on/off switch, may prevent a user from pressing a volume switch, and/or the like.

For example, the alignment image  514  may pulse as it is displayed to indicate to a user where an alignment tab of the otoscope attachment device should be displayed. For example, the alignment image  514  may pulse to indicate to the user that it is time to place the otoscope clip device onto the smart device. 
     An alignment tab of an otoscope clip, such as alignment tab  106  described herein, may comprise one or more alignment tab features that may assist in aligning the otoscope with the camera. For example, the alignment tab may be placed within, near, or over the alignment image  514 , such that one or more alignment tab features align with one or more alignment image features. The alignment tab may be aligned with the alignment image when the otoscope may be aligned with the camera. For example, the otoscope may be aligned with the camera when the one or more alignment tab features are aligned with the one or more alignment image features. 
     An alignment image feature may be complementary to an alignment tab feature. For example, the first alignment image feature may be complementary to a first alignment tab feature or a portion of the first alignment tab feature, the second alignment image feature may be complementary to a second alignment tab feature or a portion of the second alignment tab feature, and the third alignment image feature may be complementary to a third alignment tab feature or a portion of the third alignment tab feature. 
     As shown in  FIG. 5 , the alignment image  514  may be placed at a location on the display of the smart device. For example, the alignment image  514  may be an icon or file that may be placed at a location (e.g., a correct location) to allow the otoscope to be aligned with the camera. The location on the display of the smart device may be determined in a number of ways. In an example, the smart device may determine the model identity of the smart device. The smart device may use the model identity to determine the location to display the alignment image on the smart device. The location may be stored in a database, table, and/or file that may be on the smart device and/or on another computing device (e.g., a server in the cloud). The smart device may use the model identity to look up a location that may be used to display the alignment image using from the database. 
     The smart device may determine one or more dimensions of a component of the smart phone and may use the one or more dimensions to determine a location to display the alignment image. The component may be a display, a camera, and/or the like. For example, the smart device may determine one or more dimensions that may indicate the center of the camera. The smart device may use those dimensions to determine a point on the display that may be associated with the center of the camera. For example, the point on the display may be intersected by an axis that is through the center of the camera and orthogonal to the display. 
     A dimension of a component of the smart phone may be a dimension from the edge of a display that may be used to display the alignment image. A dimension may be from an edge of the display to an edge of the alignment image. A dimension may be from an edge of the display to a center of the alignment image. A dimension may be from an edge of the smart device to a center of the camera. A dimension may be a resolution of a display that belongs to the smart phone. A dimension may be a density of a display, such as the pixels per square inch (PPI), that belongs to the smart phone. 
     The alignment image may be modified and/or generated based on the model of the smart device. For example, the alignment image may be displayed at one location and size for an iPhone 6, but may be displayed at another location and size for a Samsung Galaxy S. In an example, the alignment image may be displayed at one location and size for a first display resolution of a device, and may be displayed at another location and size for a second display resolution of a device. 
     The alignment image may be displayed with a visual effect (e.g., blinking, pulsing, etc.) to indicate when a user may attach the otoscope clip device to the smart device. The alignment image may indicate where a user may attach the otoscope clip device. 
     It may be determined that the otoscope clip device is aligned with the camera, for example, using a video captured by the camera. A user may view a video and/or image (e.g., a live video and/or image) from the camera at  512 . The user may use the video to determine that the otoscope clip device is not aligned with the camera. For example, the user may determine that a portion of the otoscope may be appearing in the video, which may block a portion of the camera view. In an example, the user may determine that the otoscope clip device is aligned with the camera by viewing a full circle in the camera view. 
     A user may be able to determine that the otoscope clip device may be misaligned or detached by looking at a camera view (e.g., viewing a video and/or image from the camera) at  512 . When the otoscope clip device moves away from the camera, the camera view displayed at  512  may look different. For example, a user may see that the camera view may be cut off or that there may be black shade near or around the edges. As another example, a user may see that the camera view may not be a clear circle (e.g., a full clear circle). The camera view at  512  may ensure that the content may be reflective of the alignment and the recording that may occur. This may assist the user in understanding how to align the otoscope clip device. This may assist the user in determining that the otoscope clip device is not aligned. 
     In an example, the user may be prompted to turn up the volume in order to hear audio guidance that may be provided. In an example, the user may be prompted with a diagram and/or image of an outer ear, an inner ear, and/or an ear canal to familiarize the user with what they may see. 
     At  508 , the user may be prompted indicate which ear of a patient will be examined with the otoscope of the otoscope clip device. The user may indicate that a right ear may be examined, a left ear may be examined, or both. The user may indicate which ear is to be examined so that a recorded video may be labeled with the associated ear. 
     In an example, the user may be prompted with a tutorial video. The tutorial video may explain how the otoscope clip device is intended to work with the smart device. The tutorial video may provide an overview of how to attach the otoscope clip device to the smart device and/or how to use to otoscope. 
     In an example, the user may be prompted with visual and/or written instructions as to how to straighten an ear canal. The visual and/or written instructions may be based on the age of a patient. For example, instructions may be provided to show how to position a child to assist in straightening an ear canal. 
     At  510 , the user may be prompted to place the speculum of the otoscope into the ear canal of the patient. A video and/or an image from the camera showing a view through the otoscope may be displayed on the display of the smart device. The smart device may provide instructions to the user as to how to improve the image, how to perform the examination, how long to record, and the like. 
     The smart device may display a countdown to indicate when the user should begin recording. For example, the user may insert the speculum gently and may begin recording after a three second countdown. The smart device may notify the user that videos and/or images are being recorded. The smart device may request that the user follow an arrow displayed toward the eardrum and may instruct the user to stop if anything blocks the view. 
     The smart device may display a countdown to indicate to the user that the user may continue to keep the speculum of the otoscope in the ear canal of the patient until the countdown has completed. This may be done, for example, to provide enough time to record a video of the outer ear, the middle ear, and/or the ear canal of the patient (e.g., the tympanic membrane).
