Wearable display market is a consistently growing field to handle a smart device with ease. Wearable display is an efficient device that can show the information to the user. In this paper, propose the scheme of a wearable display using LED and implement it including controlling remotely with BLE. Traditional outdoor LED display requires the dedicated controller and its software. Therefore, to control those LED display, it should implement a driver and its own way of communication. The proposed method is to ensure the independence and extensibility by separating driver module and communication module for controlling LED display. In addition, by adopting a short-range communication with Bluetooth 4.0 and a LED driver with low-power technology, it can be showed to control system configuration and display with a smart device.

Virtual reality exposure therapy (VRET) has been used for a several decades. However, we are not aware any studies that used a smart-phone based virtual reality techniques. In this study, we suggested a new smart-phone based VRET that included photorealistic techniques. We also evaluated the current system with 32 healthy participants, and results suggested that the current system evoked different emotional valences in indoor/outdoor and familiar/unfamiliar environments. The meaning of current results and potential applications of VRET were discussed.

Recently, most of people wants to have smart life for themselves like smart phones. In this paper, we propose the smart elevator based on the laser screen, speakers and air fresheners. Using this elevator, we could enjoy the various screen inside, and we could keep contacting with manager for wifi in the emergency situation. Also, the elevator could be operated with user's motion for Kinect. Finally, we did the survey for understanding preference of smart elevator. The grops are elevator manufacturing company, elevator distribution corporation and consumers, each group have 200 people.

This thesis suggests the application to the people who are using smart phone which is based on the Android operation system that makes it available to check their call and sms by a repeater and display in the limited places such as at the swimming pool or spa. This application is designed to save user's basic information. And when the user gets a call or a sms, it can make the sender number and fundamental information a data by PhonStateListener and SmsReceiver. The data is uploaded by bluetooth of a repeater. The smart phone user can use the repeater to check the received information by display.

This paper presents a technique for an Android mobile device to best utilize its surrounding external display device such as high-definition TV, in order to overcome the size and resolution limitation of the small LCD in the mobile device. Unlike current techniques that simply expand the LCD screen image to an external large display, our technique dynamically changes the resolution adapting to capability of the external display. And, the original screen become a remote controller.

최근 스마트폰의 꾸준한 발전으로 성능이 높아졌고, 디스플레이의 대형화가 되고 있다. 디스플레이가 대형화로 스마트폰을 보기 편해지긴 하였으나, 한 손 사용이 불편해졌다. 각 제조사는 사용의 편의성를 위해 한 손 조작모드를 제공하고 있으나, 기존의 방법은 화면의 크기를 축소시키거나, 여러 단계의 메뉴를 설정해야 하고, 물리적 지원방법으로 범용성이 떨어지는 문제가 있다. 본 논문에서는 이러한 문제점을 해결하기 위해 화면의 크기를 그대로 유지하고, 기존의 마우스 커서방식을 차용한 소프트웨어 지원방식의 가상 마우스패드를 설계 및 구현하였다.

Recently, with the explosive increase of video streaming services, real-time live broadcasting has also increased, which leads to an infringement problem for user privacy. So, to solve such problems, we proposed the real image blurring system using dlib face-recognition library. 68 face landmarks are extracted and convert into 128 vector values. After that the proposed system tries to compare this value with the image in the database, and if it is over 0.45, it is considered as different person and image blurring processing is performed. With the proposed system, it is possible to solve the problem of user privacy infringement, and also to be utilized to detect the specific person. Through experimental results, the proposed system has an accuracy of more than 90% in terms of face recognition.

Recently, smart devices can be used with a variety of programs. Because of these characteristics, suitable lectures are provided to mobile device in Korea educational facilities. However, it is possible to reduce the learning efficiency from taking courses. because of many smart devices are using in a small display. Therefore, we need effectively in a small display content layout for overcome these problems. In this paper, we proposed content layer format for smart devices by Illustrated Programs based on Golden Ratio.
