In this paper, we propose and develop software controllable mobile controller contents using bluetooth concepts. The main features of the propsed system are as follows. Bluetooth communication is used for between smart phone and bluetooth. We develop two kinds of programs, clients and server, in which clients requests bluetooth communication and server responds. It's controllable to move toward the previous page and next page, and GUI environments can give efficient user oriented services. The results of performance evaluation show relatively good performances in view points of prices, functions, and portability.

In this paper we present the search on HC-06 Bluetooth based driver module for emergency LED Multi-Directional Indicator. Nowadays, a growing trends in which electronic displays such as LED, LCD or plasma monitors are being installed in public places like bars, stores, entertainment areas, restaurants, lobbies, etc. In this paper, the study is curried out on efficiency of HC-06 Bluetooth module based controller driver that relates generally to the field of emergency signage management systems for displaying various indicator contents remotely on electronic displays in public and privates venues. It allows user smart devices interaction remotely with digital signage by providing content for displaying on at least one display in a venue. Depending on the emergency case, HC-06 Bluetooth based driver module proves the high efficiency as well as good performance of processing and communicating remotely the indicator based message that is displayed from a venue management control system by using smart devices. The system combines smart device that linked to HC-06 Bluetooth module with ATmega168/328 embedded micro controller which result by switching the displayer containing the digital signage indicator based message.

Wii Remote is the primary controller for Nintendo's Wii console. A main feature of the Wii Remote is its motion sensing capability, which allows the user to interact with and manipulate items on screen via movement and pointing through the use of accelerometer and optical sensor technology. Another feature is its expandability through the use of Bluetooth. In this Study, use of motion sensors and Bluetooth capabilities. The user holding the remote on the screen, pointing to receive information about the values of the coordinates on the screen indicating the drawing of the implementation.

The audible pedestrian signal (APS) is an add-on device which connects to the pedestrian signaling device and informs the contents and changes of the signaling by sound. It provides walking direction information of the pedestrian crossing so that the blind people can safely cross the pedestrian crossing. In an intersection where a plurality of audible pedestrian signal (APS) are installed at an intersection crosswalk, existing audible pedestrian signal (APS) operate simultaneously in the communication radius of a wireless remote controller, which may cause confusion for the blind people and the public may complain about the noise. In this paper, we developed a BLE (Bluetooth Low Energy)-based audible pedestrian signal (APS) system capable of supporting two-way communications with a smart-phone that can cross the intersection safely and improve the walking comfort and traffic safety for the blind people. The proposed method is a method in which the BLE beacon communication based audible pedestrian signal (APS) presents active service to the blind people, and the existing audible pedestrian signal (APS) is a way of requesting the passive service by the blind people with the wireless remote control by the unidirectional communication based on 358Mhz. The developed system is installed in the crossroad of Doma-dong, Seo-gu, Daejeon, and it is tested and operated by the blind people. The satisfaction evaluation and analysis of the audible pedestrian signal (APS) for the blind people have good results and are planned to be expanded in the future.

The animatronics technique could be very important fact of technique not only to achieve full completion of visible image but also to offer lots of chances to express images by merging CG, special effects and special devices. In this thesis, we design and implement the Zigbee-based wireless transceiver and communication program to control animal animatronics such as a dog and bear. The wireless control utilizing the Zigbee protocol is that electrically consumption is more small than the Bluetooth and reliability of data transmission is better. The implemented control systems and program have the normal and replay function for control of animal models. This functions and operability are tested by a designed animatronics prototype under the wireless environment.

This paper proposes the wireless integrated service for controlling networked appliances. Using wireless devices such as celluar phone and PDA which can communicate through Bluetooth and CDMA technology, home appliances are accessed and controlled from outside of house. The XML and the SMS message format is designed to specify controlling information for home appliances. Also the mobile agent and the message processor for networked appliances are implemented in the home gateway. In order to verify the proposed service system, a universal remote controller for cellular phone and PDA and network appliance simulator on web browser are implemented. Correct operation is verified through simulation using them.
