These days due to the introduction of the subject classroom system, the classrooms for the subject are arranged and various advanced educational equipment is provided in the classroom such as the actual object image processor, electronic blackboard, and educational photographer which are helpful to the class. With the increase of these equipments, the number of remote controller of individual educational equipment also increases, therefore it is complicate to manage the remote controllers and teachers need to learn the usage of them. So the system supports a remote control for managing the educational equipment by the one remote controller and the instructional supplement. The system consists of the hardware which is similar to popular remote controller and the software which is installed on the teacher's PC and supports controlling the educational equipments, recording the instruction, writing on the blackboard, and automatic power off of the equipment. By introducing the system the teacher could reduce the time consumed by the equipment's control and useless electric waste.

The IPTV which was commercialized and is being serviced to customers at present has a complicated GUI (Graphical User Interface) to provide two-way services and a remote control containing more than 40 buttons unlike the conventional TV. Accordingly, the remote control becomes one of the causes that make the usability of the IPTV worsen. In this paper, we suggest a LED button guide system as a solution to improve a usability of the IPTV, and analyze the effects of the interface obtained from the user evaluation on the user action.

Today cases of using individual service on community TV are increasing with the advent of smart TV. The traditional way for using individual service like e-mail or SNS on TV is not simple and puts in too much time because it has to type so many text using remote control that is unsuitable for typing. In this paper, interaction using cube remote control is proposed in order to facilitate individual service on TV. It is simple interaction like shaking and tapping instead of a complex interaction method. In addition, it is believed that the proposed simple interaction using cube interaction might be one of great alternatives for using individual service on smart TV.

스마트 홈 환경에서 일어나고 있는 상황을 인식하고 그에 따라서 환경을 제어하는 홈서버와 홈 환경에 설치된 가전기기 사이를 연결하는 통신기술은 전력선 통신방식, 전용선 통신방식이나 무선 통신방식 등이 있다. 이는 기존 가전기기들을 가지고 있지 않는 기능들이기 때문에 기존의 홈 환경에 스마트 홈 환경을 구축하려면 제품 교체 등에 소모되는 비용이 추가로 발생하는 문제점이 있다. 이러한 문제점을 해결하기 위해서 기존의 제품들이 대부분 지원하는 적외선 리모컨 방식을 이용하여 가전기기들을 통합하여 제어하는 방법을 고안해 내었고 이를 테스트 하였다.

Infrared remote controllers are widely used in controlling electronic devices due to its simplicity and convenience. This paper presents a smart phone application unifying any infrared remote controllers. We can select a device from device list menu of the application. Any new device can be added easily by downloading the protocol file of the device from protocol file server. Remote controller protocol files are stored in audio file format, and the file related to a specific menu button is transmitted through the audio jack of smart phones. The protocol file server is a standard file server, and protocol files for various devices are collected by infrared receiver module. For smart phones without infrared facility, a small infrared module translating audio signal to infrared signal is applied.

Modem consumer electronic products like TV, VCR etc, offer users the convience of switching the equipment on and off via a remote control handset. When this type of equipments is switched off, it is said to be in standby mode. In this paper, We proposed that the method of the blocking standby power from in industrial product including electronic and electronic appliauces. This method is perfectly blocking the standby power of electrical circuit.

최근 스마트폰을 비롯한 다양한 스마트 기기들의 사용이 폭발적으로 늘어남과 동시에 이 기기들에서의 멀티미디어 콘텐츠 소비 또한 급격하게 늘어나고 있다. 이것은 자연스레 홈 네트워크 환경에서 사용자들의 DLNA 기기 간 미디어 콘텐츠 공유에 대한 욕구로 이어졌다. DLNA 기술이 등장하면서 이러한 욕구가 해소되기는 했지만 DLNA 제품 간의 효과적인 콘텐츠 상호 공유 및 재생을 제어하고 관리하는 전용의 S/W가 요구되고 있다. 이에 본 논문에서는 DLNA와 UPnP의 분석을 통하여 미디어 공유와 제어를 동시에 수행하는 스마트 리모컨 S/W의 구현 구조에 대하여 논한다.

Audible Pedestrian Signal(APS) is an additional equipment to provide information about pedestrian signals in non-visual formats such as audible tones and verbal messages. It can provide information to pedestrians about the location and directions of a crosswalk, and the traffic signal status. In general, a pedestrian who is visually impaired uses a 358.5MHz wireless remote controller to activate the APS and crosses at the crosswalk with the help of the APS. The existing APS can only receive an activation message from the remote controller. Therefore, the APS has an issue, especially at intersections, that all APSs within the communication range of the remote controller are activated simultaneously. It makes to confuse the visual impaired pedestrians. In this paper, we propose a BLE-enabled APS that can enable two-way communication via Bluetooth with a smartphone. The proposed system solves the problem and provides them with additional information, so that visually impaired pedestrians can cross at the crosswalk more conveniently.

Since various applications is converged in digital televisions, playing game on DTV will be available in the immediate future. Game programming of DTV is more difficult than that of PC in a viewpoint of game development. Since TV use very simple remote controller as user interface, mapping type, choice type, and one-button type are used among mobile game user interfaces. In addition, we suggest to use text class, numeral class, bitmap class, and shape class of DTV OSD middleware which is proven software, instead of developing new DTV-oriented game engine. The proposed interfaces can be applied in various game situations and allow intuitive and fast operations. By using OSD middleware, game actions can be subdivided into state structures, OSD objects can be used as game objects, and events and actions of remote controller keys are easily defined.

Internet of Things technology is rapidly becoming a reality in many parts of our lives through various product services, and product development especially in the field of smart home is being actively carried out. Most controllers for controlling various smart home products use smart phone applications. However, smart phone applications are not suitable as smart home controllers, contrary to smart home services that emphasize intelligence and convenience. In order to provide intelligent smart home service, intuitive form of smart home controller is needed, which enables integrated control of smart home device. Therefore, this paper proposes a smart home remote control that can control the Internet devices and services of objects. The proposed smart home remote control provides an environment where users can build a smart home service through the IFTTT(If This Then That) automated service platform.
