Abstract:
A wearable device includes a display; a sensor configured to obtain a biometric information of a user; a memory configured to store at least one instruction; and at least one processor configured to execute the at least one instruction to: based on an event related to executing an application, identify execution of biometric authentication associated with the application; based on the identification, display a message indicating information corresponding to the biometric authentication to be performed in the wearable device; obtain, by the sensor, the biometric information of the user wearing the wearable device; identify authority using the obtained biometric information and registered biometric information stored in the memory; and display, by the display, a screen associated with the executed application based on the identified authority.
Abstract:
A device for removing security on content using biometric information includes a memory configured to store content on which security has been set based on first biometric information of a user; and a controller configured to obtain second biometric information of the user, which is of a different type than the first biometric information, and remove the security on the content based on the second biometric information, in response to a user input for executing the content.
Abstract:
A head mounted device (HMD) includes an imaging unit configured to capture at least one image of a partial region of an iris, an electrocardiogram (ECG) sensor configured to receive an ECG signal, and a control unit configured to acquire at least one image of the partial region of the iris and ECG signals, and authenticate a user by using the acquired image(s) of the partial region of the iris and the ECG signals.
Abstract:
A method and a device for providing content are provided. The device includes a display configured to display content, and an interface configured to receive a first input that selects a part of the displayed content, and a second input that requests to change a size of the displayed content. The device further includes a controller configured to control the display to display the selected part of the displayed content and an unselected part of the displayed content by changing a size of the selected part and a size of the unselected part to be different from each other, in response to the interface receiving the second input.

Abstract:
Provided is a device including: a display unit configured to display handwritten content based on an analog handwritten input of a user; a user input unit that receives a user input of selecting a portion of the handwritten content displayed on the display unit; and a control unit reproduces a segment of multimedia content, which corresponds to the portion of the handwritten content, from the multimedia content synchronized with the handwritten content.
Abstract:
A method and apparatus for reproducing a portion of handwriting displayed on a screen in a same temporal manner in which the handwriting was handwritten.
Abstract:
Provided is a wearable device including: an image sensor configured to sense a gesture image of a user setting a user input region; and a display configured to provide a virtual input interface corresponding to the set user input region.
Abstract:
A method and device for controlling an irradiating light for photographing an iris is provided. The device includes a light source configured to generate light, an active lens configured to adjust a refractive index of light passing through the active lens, an image capturer configured to capture an image of the iris by using a camera, and a controller configured to control the active lens to change the refractive index of the light passing through the active lens based on distance, motion and ambient light levels.
