Disclosed is a mirror display system. The mirror display system includes a sensor module, a mirror display including an optical mirror and a display, and at least one control circuit electrically connected to the sensor module and the mirror display, wherein the at least one control circuit may determine a first angle value indicating a graze direction of a user reflected in the optical mirror through the sensor module, determine a distance value between a subject reflected in the optical mirror and the mirror display, determine a depth value of the subject on the mirror display based on the first angle value and the distance value, and display an object having a depth value corresponding to the depth value of the subject through the display.

Method for controlling depth of object in mirror display system

A device-to-device (D2D) communication method is provided. According to an inventive concept, the method comprises, storing, by a first device, first authentication data including a hash chain, which is a sequential concatenation of hash values, and storing, by a second device, second authentication data including an initial hash value of the hash chain, transmitting, by the first device, a final hash value of the hash chain to the second device, determining, by the second device, whether authentication between the first and second devices has succeeded by repeatedly hashing the initial hash value stored in the second device until a hash value identical to the final hash value is returned, and if a determination is made that authentication between the first and second devices has succeeded, performing, by the first and second devices, a connection establishment process for establishing a connection between the first and second devices.

Device-to-device communication method including device-to-device authentication using hash chain

A display device is disclosed. The display device may comprise: a memory for storing a content; a display panel for outputting at least a part of the content; multiple contact points arranged on a side surface of the display device; and a control circuit electrically connected to the memory, the display panel, and the multiple contact points.

Content display using multiple display devices

An electronic device is provided. The electronic device includes a housing, a communication circuit configured to perform short range communication with a mobile device by using a first communication channel and perform wireless communication with an external output device by using a second communication channel and a control circuit configured to, when the mobile device is located on or in close proximity to the housing, obtain content that is being output by the mobile device through the first communication channel and transmit the obtained content to the external output device through the second communication channel.

Hotel service providing method and hotel service providing system

There is provided a method for manufacturing a semiconductor device including a substrate including a plurality of active regions, a plurality of gate electrodes extending in a first direction to intersect a portion of the plurality of active regions, and including first and second gate electrodes disposed to be adjacent to each other in the first direction, a gate isolation portion disposed between the first and second gate electrodes. The gate isolation portion includes a first layer and second layers disposed on both ends of the first layer in a second direction perpendicular to the first direction.
