  • The multi-function console system in ships has currently exposed operational difficulties due to its complex interfaces although it supports a variety of functionalities. In this paper the concept of a human computer interaction (HCI) based multi-function console system is proposed, which can support intuitive operation environments by the analysis of users' needs to shipboard systems. Expert interviews and surveys are carried out in order to obtain users' requirements. Through the survey results, the HCI based multi-function console system is conceptually designed, which is optimized to the input of multi-touch screen. It is expected that the HCI based multi-function console system can provide ship operators with easy interfaces to the console system as well as safe operation in a rough ocean environment.

  • In this paper, we propose user-centric immersible and interactive electronic book based on the interface of tabletop display. Electronic book is usually used for users that want to read the text book with multimedia contents like video, audio, animation and etc. It is based on tabletop display platform then the conventional input device like keyboard and mouse is not essentially needed. Users can interact with the contents based on the gestures defined for the interface of tabletop display using hand finger touches then it gives superior and effective interface for users to use the electronic book interestingly. This interface supports multiple users then it gives more diverse effects on the conventional electronic contents just made for one user. In this paper our method gives new way for the conventional electronics book and it can define the user-centric gestures and help users to interact with the book easily. We expect our method can be utilized for many edutainment contents.

  • With recent rapid development of computer capabilities, various technologies that can facilitate the interaction between humans and computers are being studied. The paradigm tends to change to NUI using the body such as 3D motion, haptics, and multi-touch with GUI using traditional input devices. Various studies have been conducted on transferring human movements to computers using sensors. In addition to the development of optical sensors that can acquire 3D objects, the range of applications in the industrial, medical, and user interface fields has been expanded. In this paper, I provide a model that can execute other programs through gestures instead of the mouse, which is the default input device, and control Windows based on the lip motion. To propose a model which converges with an Android application and can be controlled by various media and voice instruction functions using voice recognition and buttons through connection with a main client. It is expected that Internet media such as video and music can be controlled not only by a client computer but also by an application at a long distance and that convenient media viewing can be performed through the proposal model.

  • Biometrics are methods of recognizing a person based on the physiological or behavioral characteristics of his of her body. They are highly secure with little risk of loss or falsification by others. This paper has designed and implemented a security system of biometrics by precisely measuring heartbeat signals at two fingertips and using a photoplethysmogram, which is applicable to biometrics. A performance evaluation has led to the following result. The security system of biometrics for personal authentication which has been designed and implemented by this study has achieved a recognition rate of 90.5%. The security system of biometrics suggested here has merits of time saving and easy accessibility. The system is touch-based and collects the necessary biometrics information by simply touching the machine with fingers, so anyone can utilize the system without any difficulty.

  • Since domestic and foreign platform companies and mobile carriers adopt and use different kinds of smart platforms, developers should develop or convert contents according to each smart platform to provide a single smart content for customers. It takes long time and a lot of money to convert the conventional smart contents in order to serve other smart platforms. For the reason, more attention has been paid on Smart Cross Platform or Hybrid Platform, the core technologies of OSMU(One Source Multi Use) in which, once a program is coded, it can be executed in any platforms regardless of development languages. As a result, PhoneGap and HTML5 based Sencha Touch have been introduced. In this paper, we developed the smart virtual machine, which is built in smart cross platform based smart devices, unlike Android, iOS, Windows Phone devices being dependent of platforms, and helps to download and execute applications, being independent of platforms. the smart virtual machine supports C/C++, and Java language, being differentiated from JVM by sun microsystems that supports only Java language and .NET framework by microsoft that supports only C, C++ and C#. Therefore, it provides contents developers with the environment where they can get a wide range of options in choosing a language and develop smart contents.

  • Tabletop games have been applied to improve the ability of social collaboration based on the characteristics that more than two people simultaneously interact on the tabletop. Especially, the tabletop games can be used as an educational tool for children with autism when it is implemented by considering educational and psychological models for children's behavioral characteristics. However, the previous collaborative games were designed for only disabled children so that it is hard to reflect cognitive and humanistic effects in inclusive education, where disabled children and non-disabled children interact in a same spatiotemporal environment. In this paper, therefore, we design a collaborative game on a multi-touch tabletop to enable spontaneous communication between disabled children and non-disabled children. Through user study, we evaluate the improvement in terms of the positive interaction and the degree of attention by comparing with a conventional collaborative game(e.g., a board game). We found that negative interaction including disabled children's abnormal behavior decreased and positive interaction such as body gestures and verbal communications increased. In addition, the tabletop game supported high immersiveness to all children by deriving equal level of attention time including individual and joint attention. We anticipate that the proposed game design can be utilized to develop collaborative contents for people with differences on sociality and cognitive ability.

  • Recently the CPU performance of modem chipsets or multimedia processors of mobile phone is as high as notebook PC. That is why mobile phone has been emerged as a leading ICON on the convergence of consumer electronics. The various applications of mobile phone such as DMB, digital camera, video telephony and internet full browsing are servicing to consumers. To meet all the demands the image quality has been increasingly important. Mobile phone is a portable device which is widely using in both the indoor and outside environments, so it is needed to be overcome to deteriorate image quality depending on environmental light source. Furthermore touch window is popular on the mobile display panel and it makes contrast loss because of low transmittance of ITO film. This paper presents the image enhancement algorithm to be embedded on image enhancement SoC. In contrast enhancement, we propose Clipped histogram stretching method to make it adaptive with the input images, while S-shape curve and gain/offset method for the static application And CIELCh color space is used to sunlight readability enhancement by controlling the lightness and chroma components which is depended on the sensing value of light sensor. Finally the performance of proposed algorithm is evaluated by using histogram, RGB pixel distribution, entropy and dynamic range of resultant images. We expect that the proposed algorithm is suitable for image enhancement of embedded SoC system which is applicable for the small-sized mobile display.

Therefore, the authors of this paper studied the physical deformations and characteristics of flexible displays by user manipulation through literature and case studies. This research suggests the following guidelines for a flexible display interface design for the user experience. First, it must be designed to provide the functionality that users need in a variety of display environments. Second, in using the interface, external factors should be removed from the viewing angle of multi-users. Third, all possible user actions should be considered on flexible displays other than touch and contact. Fourth, flexible design of flexible display requires changing interface design for user experience.
