Abstract:
Provided is a method, performed by an augmented reality (AR) device, of measuring a user's vision. The method includes: obtaining, by using a camera of the AR device, a background image including an image of at least one physical object; identifying an edge of the image of the at least one physical object in the background image; determining a first region for measuring the vision of the user on the background image based on the edge of the image; determining a second region corresponding to the first region on a display of the AR device; outputting a virtual object for measuring the vision of the user to the second region; obtaining a user input signal for vision measurement after the outputting the virtual object; and determining a vision prescription value of the user based on the user input signal.

Abstract:
A storage device is configured to be connected to a host device via a physical cable which includes a power line and a data line. The storage device includes a non-volatile memory, a data path controller configured to temporarily deactivate the data line while power is supplied from the host device via the power line, and a memory controller. The memory controller includes a biometric module configured to receive biometric data and perform user authentication based on the biometric data; a biometric processing circuit configured to change a state of the memory controller, based on a result of the user authentication; and a data processing circuit configured to encrypt and decrypt data. The data path controller is configured to temporarily deactivate the data line in response to the changed state of the memory controller.
Abstract:
According to certain embodiments, an electronic device may include a temperature sensor sensing temperature information, a processor, and a touch circuit. The touch circuit may identify that the temperature information is lower than or equal to a designated threshold temperature, and may identify whether values included in pieces of touch sensing information are within a designated range. Each of the pieces of touch sensing information may include multiple values corresponding to multiple nodes of the touch circuit. On the basis of the result of identifying whether the values included in the touch sensing information are within the designated range, the touch circuit may not output touch information associated with at least one first node having a value within the designated range, to the processor. Alternatively, the touch circuit may output touch information associated with at least one second node having a value outside the designated range, to the processor.
Abstract:
A diffusion lens includes a concave first lens surface, a convex second lens surface such that part of light incident on the first lens surface is output from the second lens surface, a side surface extending from a periphery of the second lens surface in a vertical direction of the diffusion lens such that part of the rest of the light incident on the first lens surface is output from the side surface, and a bottom surface extending from a periphery of the first lens surface in a horizontal direction of the diffusion lens to meet a periphery of the side surface. Rates of change of the first and second lens surfaces have the same sign. A pattern is formed on the side surface and the bottom surface to diffuse the light through the side surface and diffuse the light reflected by the bottom surface.
