Abstract: A process for assessing at least one characteristic of a user's vision includes determining a characteristic of at least one camera of a mobile device; using the at least one camera, capturing at least one image of an object; determining, with reference to a portion of the at least one image composed of the object, a distance from the mobile device to the object at a time of capture of the at least one image; and receiving input from the user in response to material presented on the object.

Abstract: A method of operating a pupillary distance system is disclosed. The method comprises the steps of capturing, with at least one camera of the pupillary distance system a 2D image and a corresponding 3D depth map of a face of a subject. A determination of pupil localization information is made using the 2D image and corresponding 3D depth map. The pupil location is further refined based on the pupil localization information. Pupil center coordinates are determined and the pupillary distance is calculated for a subject between centers of each pupil. Processes and uses thereof are also disclosed.

Abstract: A frame comprises a front portion, connecting members, a first arm coupled to a first connecting member by a hinge, and a second arm coupled to a second connecting member by a hinge. The first and second connecting members are coupled to the front portion by hinges. The first arm is rotatable, relative to the first connecting member, about a first pivot axis, and the second arm is rotatable, relative to the second connecting member, about a second pivot axis. The first pivot axis and second pivot axis are parallel to each other and positioned at an angle relative to lengths of the first and second arms, respectively. The first and second connecting members are rotatable, relative to the front portion, about a third pivot axis, which is positioned at an angle relative to the first pivot axis and the second pivot axis.

Abstract: A system may include an image capture device a processor communicatively coupled to the image capture device. The image capture device may be configured to obtain one or more images. The processor may be configured to receive a first image obtained by the image capture device, determine if a first object is in the first image, determine if a size and a location of the first object in the first image meet threshold values if the first object is determined to be in the first image, determine at least one corrective action to be taken if at least one of the size and the location of the first object in the image does not meet the threshold values, and cause an instruction for taking the at least one corrective action to be communicated to a user. Methods and machine-readable storage media also are disclosed.

Abstract: A system includes a computing device including a processor communicatively coupled to a camera. The computing device is configured to, in response to receiving a request, capture an image via the camera and detect, within the image, a first plurality of locations of a first object. The computing device is further configured to segment the first plurality of locations of the first object by determining, for each location of the first plurality of locations, a likelihood the corresponding location includes a part of the first object. The computing device is configured to inpaint a second plurality of locations with an associated likelihood the corresponding location includes the part of the first object above a threshold value. The computing device is additionally configured to generate an augmented image by superimposing a selected second object over the image and display the augmented image on a user interface of the computing device.

Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for virtual try-on of items such as spectacles. A virtual try-on interface may be implemented at a server or at a user device, and may use collision detection between three-dimensional models of the spectacles and of a user's face and head to determine the correct size and position of the spectacles for virtual try-on. With the determined size and position, a virtual representation of the spectacles is superimposed on an image of the user.

Abstract: A server in communication with a first device capable of receiving input from a camera attached to the first device, and a second device capable of displaying output, is provided. The server is configured to receive, from the first device, data relating to characteristics of the camera and characteristics of an image obtained by the camera of a screen of the second device; determine a screen pixel length of the screen; and provide instructions to the second device to display on the screen an object at a desired visual angle in response to the data received from the second device and the screen pixel length, while the first device is positioned at an arbitrary distance from the screen.

Abstract: Spinnable frames for spectacles are provided. A spinnable frame allows a user to hold a distal end of one of the temples and freely spin the remainder of the spectacles around that end of the temple. A spin joint is provided in at least one of the temples that allows this spinning action. The spin joint may span an interface between the distal end of the temple and a proximal end of the temple, the proximal end being coupled to a front portion of the frame at a hinge interface. In this way, the temple arm is allowed to fold against the front portion for compact storage, as with conventional eyeglass frames, while facilitating spinning of the spectacles in a way that avoids excess forces on the hinge interface and/or other portions of the frame or lenses mounted therein.

Abstract: A method for virtual try-on of user-wearable items is provided. The method includes capturing, in a client device, a first image of a user, the first image including a reference token for a user-wearable item and displaying, in the client device, images of multiple user-wearable items for the user, receiving an input from the user, the input indicative of a selected user-wearable item from the user-wearable items on display. The method also includes segmenting the first image to separate the reference token from a background comprising a portion of a physiognomy of the user, replacing a segment of the reference token in the first image with an image of the selected user-wearable item in a second image of the user, and displaying, in the client device, the second image of the user.

Abstract: A lensmeter system may include a mobile device having a camera. The camera may capture a first image of a pattern through a lens that is separate from the camera, while the lens is in contact with a pattern. The mobile device may determine the size of the lens based on the first image and known features of the pattern. The camera may capture a second image of the pattern, while the lens is at an intermediate location between the camera and the pattern. The second image may be transformed to an ideal coordinate system, and processed determine a distortion of the pattern attributable to the lens. The mobile device may measure characteristics of the lens based on the distortion. Characteristics of the lens may include a spherical power, a cylinder power, and/or an astigmatism angle.

Abstract: Systems and methods for vision test and uses thereof are disclosed. A method may be implemented on a mobile device having at least a processor, a camera and a display screen.

The material presented on the display screen may be for assessing at least one characteristic of the user's vision. Mobile devices and non-transitory machine-readable mediums having machine-executable instructions embodied thereon for assessing a user's vision also are disclosed.

Fit information can be provided for a group of frames or for each individual frame selected by the user. The fit information can be provided with a static image of the frames and/or within a virtual try-on operation in which the frames are virtually placed on a real-time image of the user.
