For the service and creation of new space, the next generation smart device for interactive space using tailor-made contents process serve as an opportunity for the growth of new special display due to the integration of the latest digital technology. The application of next generation technology is in the field that most people expect. So, this thesis serving as the beginning, it is hoped that the smart mirror and wall industry in Korea will play a practical and academic momentum. An interactive environment which is the smart device can be realized when space displays based on smart device built on the experience of the user can provide various tailor-made processes such as academics, performances, meetings, virtual experience, exhibits and promotion, and through this a strategic direction was suggested for the development of each field.

Interactive-typed devices and contents that have been often applied in the field of entertainment and game are the technology that allows you to maximize the enjoyment and participation of users through the interaction of each. In this paper, we designed an interactive-typed smartphone app that is based on the Android platform, implemented the wearable Bluetooth device to control via a interactive interface with a vibration sensor and three-axis acceleration sensor. We tested the functionality and 3-axis motion's operability by using smartphone app, interface interactive-typed device that has been developed, prove useful as a wearable Bluetooth device that has the convenience of the user. Further, it is shown that by implementing the optimized protocol of the sensor data transfer over Bluetooth, it is possible to reduce the malfunction of the content of the smart phone.

Interactive media is a method of communication in which the output from the media comes from the input of the users. The interactive media lets the user go back with the media. Interactive media works with the user's participation. The media still has the same purpose but the user's input adds the interaction and brings interesting features to the system for a better enjoyment. We need a digital content using a dynamic motion and gesture of the mobile device. We made an authoring tool for content producers to easily create interactive content. We have tried to take advantage of the interaction by using a touch screen and a gravity sensor of the mobile device. This interaction may lead to allow the user to participate in the content, it can be used as a key device to assist in engagement. Furthermore, our authoring tool can be applied to various fields of publishing content.

An interactive web-based teaching tool for a power semiconductor course at the University of Central Florida is presented in this paper. A novel approach is introduced using Technology Aided Design Tools (TCAD) to generate time-lapsed 2D semiconductor device cross-section embedded in a webpage using $Adobe^{(R)}$ Flash (web design tool) platform to create interactive movies that demonstrate complex device physical phenomenon. Students can step through the interactive movies forward, backward, pausing, or looping. Each step represents a giving bias condition. Current-voltage plots are represented along with the semiconductor device and a visual point is placed on the IV curve to indicate the current bias conditions. The changes are then reflected in the 2D cross-section movie area and the IV plot. This tool was implemented in a classroom setting to augment the lectures or for discovery learning.

IoT technology application has been part of modern people's everyday life. This technology makes people to depend on smart devices. 'Smartphone' is the most typical example. Despite the advantages given by this device, the bad side effects are also notable. This paper presents interactive content on the dependence of smartphone device. The research objective is to make individuals to reduce the use of smartphones by realizing their own problems of smartphone dependency. Research was progressed by analyzing aspects obtained from users participating in the self-developed interactive game contents. As a result of the analysis, approximately 68% of people were aware of the problem through this content. This indicates the potential of using convergence research in interactive contents with other fields furthermore.

Due to the miniaturization and the network supporting functions of home appliances, there is growing need for mobile environment home network system which provides flexibility, mobility and convenience to users. In this environment, a interactive authentication between mobile devices is important but the related works have no enough convenience to users. This paper proposes a interactive device authentication mechanism using Home Robot and also shows its design and implementation.

In this paper we have studied about the interconnection technology between tablet device and interactive white board(IWB) system. For this study we have implemented the board writing software for both tablet device and interactive white board system which has contents management, page turning and basic writing functions. Then we defined the data format to communicate the control information and board writing information between two devices, and implemented the communication module for the real-time bidirectional communication by using the Socket programming. The page turning or writing information on tablet device were transferred to the IWB system in real-time and vice versa. From the result of performance test based on the error rate, latency time and communication coverage we derived that our implementation software has good performance between tablet device and IWB system. Also from the result of field test we proved that our solution is well suitable to use in real education environment.

In this paper, we develop IoT-HiAS(IoT-Human Interactive Advertising Service) for sharing economy. The HiAS device shooting the front of the device via a webcam and recognizes the person in real time through the SSD model using MobileNet. If the number of persons above the set threshold is recognized by counting the recognized person, the advertisement is reproduced on the idle resource through the beam projector. At the same time as the advertisement is reproduced, the captured image of the advertisement start time in the front of the device and the number of recognized persons are sends the IoT server of an oneM2M-compliant HiAS server using the IoT client. When the advertisement is finish, the webcam is shooting the front of the device and the image is sends the IoT server. We implemented the IoT-based human interactive advertising service by transmitting the received data to the advertiser and the advertising producers through the SNS(Social Network Service) agent of the HiAS server.

In this study, we assessed the performance of the test remote pointing device that is applicable to interactive TV (iTV). An empirical test was carried out with the pointing devices in three different interface methods that are recently tried in the industry. For the measurement, a directional task was performed on the linear track described in the conventional ISO 9241-Part 9. The measured variables included the movement time, accuracy, throughput and the subjective satisfaction. The result showed that the motion time was better in the device in the GyroPoint method than the other devices, but the accuracy of the GyroPoint device was lower than that of the devices in the Hall Mouse and OFN methods. It was found that the throughput and the subjective satisfaction were dependent upon the individual input devices. Since this study was conducted on the major point devices that are currently tried and analyzed the problems and characteristics, it is assumed that this study will provide useful data for the design of the remote pointing device that is more suitable to the iTV environment.
