A device includes memory and a processor. The device receives biometric information. The device receives location information. The device analyzes the received biometric information with stored biometric information. The device analyzes the received location information with stored location information. The device determines whether the received biometric information matches the stored biometric information. The device determines whether the received location information matches the stored location information. The device sends an electronic communication that indicates whether the received biometric information matches the stored biometric information and whether the received local information matches the stored location information.

Images perceived to be substantially full color or multi-colored may be formed using component color images that are distributed in unequal numbers across a plurality of depth planes. The distribution of component color images across the depth planes may vary based on color. In some embodiments, a display system includes a stack of waveguides that each output light of a particular color, with some colors having fewer numbers of associated waveguides than other colors. The stack of waveguides may include by multiple pluralities (e.g., first and second pluralities) of waveguides, each configured to produce an image by outputting light corresponding to a particular color. The total number of waveguides in the second plurality of waveguides is less than the total number of waveguides in the first plurality of waveguides, and may be more than the total number of waveguides in a third plurality of waveguides, in embodiments where three component colors are utilized.

A computer-implemented method of searching for a region indicative of a pathology in an image of a portion of an eye acquired by an ocular imaging system, the method comprising: receiving image data defining the image; searching for the region in the image by processing the received image data using a learning algorithm; and in case a region in the image that is indicative of the pathology is found: determining a location of the region in the image; generating an instruction for an eye measurement apparatus to perform a measurement on the portion of the eye to generate measurement data, using a reference point based on the determined location for setting a location of the measurement on the portion of the eye; and receiving the measurement data from the eye measurement apparatus.

An image processing method performed by a processor and including: a step of acquiring a choroidal vascular image; a step of detecting a vortex vein position from the choroidal vascular image; a step of identifying a choroidal vessel related to the vortex vein position; and a step of finding a size of the choroidal vessel.

A method for binocular ranging for children is provided in this disclosure, which includes following steps: acquiring an image of a target area and world coordinates of a human body in left and right eyes; correcting the image to obtain a corrected image of the target area; performing face detection on the corrected image of the target area to obtain a face image and an eye image; recognizing the face image and determining whether the face image is a child's face; if yes, performing image correction based on the obtained face image; inputting the eye image into a preset eye recognition model for recognition whether the human eye is staring at a screen; and performing ranging on the eye image based on the world coordinates of the human body to obtain a distance between the screen and the human eye, if the human eye is staring at the screen.

In authentication using sensor information, both reduction of processing burdens and assurance of security can be achieved.

Provided is an information processing device including an authentication unit configured to authenticate a user on the basis of collected sensor information, and the authentication unit authenticates the user on the basis of a single feature quantity extracted on the basis of sensor information collected by at least two sensors and a single registered feature quantity extracted on the basis of sensor information collected in advance by the at least two sensors.

Embodiments pertain to a method for characterizing a droopy upper eyelid performed on a computer having a processor, memory, and one or more code sets stored in the memory and executed in the processor. The method may comprise capturing an image of a patient's facial features comprising an eye and a droopy upper eyelid; identifying at least one geometric feature of a pupil of the eye within the image; and determining, based on the at least one geometric feature, whether the droopy upper eyelid is vision impairing or not, or whether the droopy upper eyelid is more likely vision impairing than not vision-impairing.

Disclosed is a method of identifying dementia by at least one processor of a device. The method includes performing a first task that causes a first object to be displayed on a first region of a screen displayed on a user terminal; and when a preset condition is satisfied, performing a second task that causes at least one object, which induces the user's gaze, to be displayed instead of the first object on the screen of the user terminal.

Disclosed in some examples are devices, methods, systems, and machine-readable mediums for enhanced meeting room solutions to provide increased inclusiveness for both remote and in-room participants for network-based communication sessions, such as hybrid network-based communication sessions. Content of a first type is placed in a location exclusive of a discontinuity in a display device and content of a second type is placed in a location inclusive of the discontinuity of the display device.
