An estimated 1 billion mobile phone were sold globally in the year 2006. In Korea, people watch television 3.17 hours in a day. Television isn't what it used to be. Digital TV provides both interactivity and high definition. Mobile phone also transferred from 2G to 3G or 3.5G. This means the complexity of TV and mobile phone is increased, design of user interface is more difficult. Unlike the personal computer industry, TV and mobile phone industries have no standard user interface. A comparative study for user interface between TV and mobile phone is studied. User, task, system are analyzed in requirement analysis. User interface model and interaction are also analyzed between TV and mobile phone. This study provides some insights for user interface design. First, the UI designer have to consider another products because one user using one product at the same time using another products. Experience for one product affects that for another product. Second, TV and mobile phone show very similar pattern, especially interaction task and input interaction. Third, there are not sometimes optimized experience between service operator and device manufacturer. Cooperative design between them is required.

This paper suggests user interface method with wearable computer by means of detecting gaze under HMD, head mounted display, environment. System is derived as follows; firstly, calibrate a camera in HMD, which determines geometrical relationship between monitor and captured image. Second, detect the center of pupil using ellipse fitting algorithm and represent a gazing position on the computer screen. If user blinks or stares at a certain position for a while, message is sent to wearable computer. Experimental results show ellipse fitting is robust against glint effects, and detecting error was 6.5％, and 4.25％ in vertical and horizontal direction, respectively.

This paper is a research on the dynamic signature verification of error rate which are false rejection rate and false acceptance rate, the size of signature verification engine, the size of the characteristic vectors of a signature, the ability to distinguish similar signatures, the processing speed and so on. Also, we present our efficient user interface and performance results.

본 논문에서는 GUI(Graphical User Interface)를 이용하여 다수의 드론을 동시 제어하는 시스템 구현 결과를 보인다. 네트워크 소켓(Network Socket) 응용 프로그램인 Packet Sender를 이용하여 다수의 드론을 AP(Wireless Access Point)에 연결하였다. Python 응용 프로그램으로 UDP(User Datagram Protocol) 소켓을 통해 AP에 연동된 드론으로 명령을 전송하여 제어한다. Python GUI 모듈인 Tkinter를 이용하여 사용자에게 GUI를 제공함으로써 접근성(Accessibility)을 높인 시스템을 개발하였다.

Hand posture recognition is an important technique to enable a natural and familiar interface in HCI(human computer interaction) field. In this paper, we introduce a hand posture recognition method by using a depth camera. Moreover, the hand posture recognition method is incorporated with MPEG-U based advanced user interaction (AUI) interface system, which can provide a natural interface with a variety of devices. The proposed method initially detects positions and lengths of all fingers opened and then it recognizes hand posture from pose of one or two hands and the number of fingers folded when user takes a gesture representing a pattern of AUI data format specified in the MPEG-U part 2. The AUI interface system represents user's hand posture as compliant MPEG-U schema structure. Experimental results show performance of the hand posture recognition and it is verified that the AUI interface system is compatible with the MPEG-U standard.

Recently, there is study about interface for user convince. this users interface technology can apply to UI depend on user choice. For that, W3C study various technology which is N-screen service on different device, provide consistent service, and UI adjust service depends on user preference. Therefore, we need UI study based on this model and standard technology. In this paper, study UI technology based on basic model to develop UI for user's convenience. So it can be useful to apply next-generation Web applications and secure web-application measure plans.

The user interface is the medium, which provides the users to have an access to the web-based information system. The user interface is the means of improving usability and accessibility for the user, as well as being the core component in the web-based information system. In this paper, the audit framework of the user interface was developed to upgrade the usability and accessibility; it was based on the three basic components of the current audit framework in the web-based information system. At the time of an audit, the UI process of the 'Analysis', 'UI Design', 'UI Production', and 'Test' was defined, which was analyzed through the web development methodology. Also, for the area of an audit, the 'Information', 'Design', and 'Technology' were defined by the analysis of the components that makes up the user interface, From the view of an audit, the standard criteria of an assessment were set as 'Usability', 'Accessibility', and 'Cross Browsing'. Through the framework that was proposed in this paper, practical audit applies the performed examples. By this, the efficiency of the proposed framework was verified.

Until recently, ind ustrial designers designed the product packaging of Eletronic Media, and userInterface designers focused primarily on software design, But as computer related technology continues to evolve, this distinction has become ambiguous, As a natural consequence of these trends, industrial designers are getting more involved in user-interface design to develop interactive objects, Moreover, In the future, the whole Information of a product whIch means product packaging, marketing, training matenals, support as weIl as hardware and software will be regarded as a product, and user's entIre expenences including the material elements of product will be taken for the factors of user interface to expand the category of user interface design. The importance of interface design and its applications within industrial design has been stressed in the recent years, However researches on practical process in interface design developments have been rarely established. This paper aims to develop the interaction design process for the useful user-interface design by theoretical study and actual analysis of user-interface design.

An ubiquitous environment has been developed in order to allow users to use information more easily. These environments are based on advanced development of mobile ubiquitous hardwares. Currently, a various user interfaces are developed for mobile ubiquitous devices using the graphic or voice. In this paper, propose a specialized graphical user interface which is based on analysis of a user profile. This user interface can provides suitable interface for individual users using XML information on the small screen of mobile ubiquitous devices.
