하나의 물리 머신만으로 복수개의 가상 머신을 지원할 수 있는 가상화 기술[5,6]이 발달함에 따라, 기업에서는 비용 절감을 위해 가상 데스크탑 기술 도입이 많이 이루어지고 있다. 또한, 일반 사용자들을 위한 가상 데스크탑 기반의 클라우드 서비스 역시 많이 소개되고 있는데, 이러한 가상 데스크탑의 효과적인 사용을 위해서는 원격 접속 기술이 필수적이지만, 이는 키보드, 마우스 및 디스플레이가 감추어져 있는 PC와 같은 정형적인 컴퓨터 환경에서만 접속이 가능하다[3,4]. 본 논문에서는 스마트폰을 이용하여, 사용자 주변에서 원격 컴퓨팅 장치로 사용할 수 있는 LCD TV, 키보드 등의 레거시 디바이스를 검색하고 해당 디바이스를 원격지에 있는 가상 데스크탑과 연계시켜[1,2] 사용자 주변의 디바이스를 통해 원격 가상 데스크탑 제어를 연계 할 수 있는 중계 소프트웨어에 대한 설계 및 구현 내용을 기술하고 있다.

Recently mobile users can access to internet using smart phone at any place and any time, through which they can search and share information. In addition, as the sensors with high-tech functions become cheaper and miniaturized along with the development of MEMS (micro-electo mechanical systems) technology, the extent to utilize smart phone is increasing. Smart phone is equipped with various sensors such as high-resolution camera, GPS, gyroscope and magnetic sensor, which is an appropriate system configuration for remote monitoring research using camera. The remote monitoring system requires camera for video and internet network to send video, for which it has a limitation that it is influenced by the monitoring location. This study is aimed to design and develop the monitoring app. which can be remotely monitored using smart phone technology. The developed monitoring app was designed to take images of ROI (region of interest) within the specified time and to automatically send the images to the server. The developed app. is also possible to be remotely controlled by SMS (short message service). The monitoring proposed in this study can take high-resolution images using CMOS built in the smart phone and send the images and information to the server automatically at any place and any time using 3G and Wi-Fi networks.

This paper proposes a method to track the center of pupil and perform the remote control for interface based on the substituted commands according to movements of pupil under smart phone environment. The proposed method, which is a remote control through the movement of eyes, may be helpful for the handicapped people or users who want a more convenient input method. A method based on webcam, which is representative one among the previous methods to track pupil of user, has a few limitations on distance and angle between location of user and webcam. However, this paper uses smart phone that is convenient to carry. The proposed method can perform the remote control through tracking of pupil using wireless network without any restriction on the location of users. Thus, the method is effectively applied for controlling the smart TV that should be controlled on the distance as well as the remote control for PC.

시각장애인은 주변 인지 장애로 정보 습득이 어렵고, 공간 정보 습득에 있어서 제약이 있는 신체조건으로 이동에 불편을 겪는다. 또한 특정 상황에서 적절한 분위기를 인지하고 그에 맞는 대응을 하기가 어렵다. IoT 시대에 맞춰 홈 네트워크 시스템이 널리 보급되어지는 추세이지만, 여전히 시각장애인이 사용하기에는 많은 어려움이 있고, 불편을 호소하는 게 현실이다. 본 논문에서는 이러한 시각장애인을 위해 스마트폰을 이용해 음성으로 집안의 사물을 원격 제어하는 구글 음성인식 홈 리모트 컨트롤 시스템을 제안한다.

In this paper, we designed a product that can prevent environmental pollution, waste of resources, and leakage of foreign currency by commercializing a green IT solution by merging a used smart phone with the IoT object communication technology for the first time in the world. For the experiment of the designed system, various performance and communication condition was experimented by installing it in the actual crop cultivation facility. As a result, when a problem occurs, the alarm sound and video notification are generated by the user's smart phone, and remote control of various installed devices and data analysis in real time are possible. In this study, it is thought that the terminal management board developed for the utilization of the used smart phone can be applied to various fields such as agriculture and environment.

Manipulating a car navigation system while driving can lead to car accident due to loss of concentration. This will be more serious for elders or beginner drivers. Recently, a new Road Traffic Law in Korea prohibits drivers from watching or operating any video displaying devices. So the car navigation system came hard to use. In order to solve the issue we design and implement a novel system where a remote person can control the car navigation system on behalf of the driver. In the proposed system, we suggest to utilize the driver's smartphone for allowing sharing the Internet connection of the phone with the navigation system. The required smartphone application and the server will also be designed and implemented.
