Abstract: Disclosed are a wearable device and controlling method thereof. The present invention includes a flexible surface light source, a photo panel located on a top surface of the flexible surface light source, and a controller coupled with the flexible surface light source and the photo panel. The controller is configured to detect a first biometric image by controlling the flexible surface light source and identify a user by comparing the detected first biometric image to a second biometric image previously saved in a memory.

Abstract: An apparatus and method for measuring 3-dimensional (3D) interocular crosstalk is disclosed. A light sensor detects luminance of a stereoscopic image displayed in a display and outputs a luminance value indicating the detected luminance. A controller calculates 3D interocular crosstalk based on a gray difference and a residual luminance ratio.
Abstract translation: 公开了一种用于测量三维（3D）双眼串扰的装置和方法。 光传感器检测显示在显示器中的立体图像的亮度，并输出表示检测到的亮度的亮度值。 控制器基于灰度差和残余亮度比来计算3D对讲串扰。
