Abstract:
A printing device for transferring an image representing contents on electronic paper is provided. The printing device includes an electronic paper controller for generating a control signal for transferring the image and outputting the generated control signal to the electronic paper, a touch sensor on a top surface of which the electronic paper is disposed to detect a user input command, a touch sensor controller for outputting a control signal to the touch sensor for driving the touch sensor and receiving the user input command detected by the touch sensor, and a main controller for controlling the electronic paper controller to change an image displayed on the electronic paper according to the user input command input from the touch sensor controller.
Abstract:
A wearable device and a method of outputting a virtual image by the wearable device area provided. The wearable device includes a projection type display unit that includes a variable lens and configured to project a light forming an image, a first sensor configured to detect a light reflected from an eye of a user, and a processor configured to control to display the virtual image on the projection type display unit by controlling one of a location of the variable lens and refractive power of the variable lens based on retina image information corresponding to the detected light.
Abstract:
A portable terminal provided with a cover is provided. The portable terminal includes a main body including an input/output unit; a cover attachable to and detachable from the main body, and provided with an output unit; a first sensor that detects folding/unfolding of the cover; and a controller that controls an output of the input/output unit or the output unit according to a detection signal of the first sensor.
Abstract:
A method and an apparatus are provided for performing wireless communication between terminals. An inquiry message is transmitted to a neighboring terminal. An inquiry response message is received from the neighboring terminal. It is determined whether the apparatus overlaps the neighboring terminal. When the apparatus overlaps the neighboring terminal, paging is automatically performed, without intervention of a user of the apparatus, and pairing between the apparatus and the neighboring terminal is established.
Abstract:
Provided is electronic paper that includes an imaging sheet for displaying content, a memory for storing the content, a mode switch unit for manually setting an operation mode of the electronic paper, and a controller for performing at least one operation from a plurality of operations including encryption of the content stored in the memory, deletion of the content stored in the memory, deletion of content displayed on the imaging sheet from a screen, and display of a lock screen that requires input of a password on the imaging sheet, according to an operation mode that is set by a user using the mode switch unit.
Abstract:
A method of operating a broadcasting receiver for payment. The method includes extracting an identifier code that is being displayed, receiving payment information matching to the identifier code from a portable terminal, and combining information extracted from the identifier code with the payment information and requesting payment approval to a payment service provider.
