Evaluation of user interfaces has to be performed in an intuitive and subjective manner by experts especially when the problem comes to the complexity and consistency of sophisticated interface procedures. The manual analysis and evaluation of logical interfaces also tends to be slow and laborious. To make the evaluation more formal and objective, the criteria and the procedure with which the evaluation can proceed must be explicitly prescribed. Furthermore, to make the formal procedure as practical as subjective expert evaluation, the criteria must reflect the user knowledge of the target tasks since the task knowledge plays the role of a basis for users to understand the interface organizations and procedures. This paper describes ESTIM, a support system for task-based evaluation of user interface, that includes the interface evaluation criteria and implies an evaluation procedure. The support system can be used either in an interactive manner by the analyst during the evaluation or in an automatic evaluation mode. It was verified that the result of automatic evaluation by ESTIM matched the results of expert evaluation fairly well.

In this paper, we proposed an interactive GUI (Graphical User Interface) system to model buildings with an editable script. Our system also provides probabilistic finite-state machine (PFSM) to define the relationships of sub-models with transformation matrices and transition probabilities for constructing new novel building models automatically. User can not only get various building models by PFSM but also adjust the probabilities of sub-models from PFSM to get desired building models. As shown in the results, the various and vivid building models can be constructed easily and quickly for non-expert users. Besides, user can also edit the script file which is provided by our system to modify the properties directly.

We are developing a simple low-cost wind velocity sensor based on small microphones. The sensor system consists of 4 microphones covered with specially shaped wind screens, 4 pre-amplifiers that respond to low frequency, and a commercial sound interface with multi channel inputs. In this paper, we first present the principle of the sensor, i.e., technique to successfully suppress the influence of external noise existing in the environment in order to determine the wind velocity and the wind direction from the output from a microphone. Then, we present an application for generating realistic motions of a virtual tree swaying in real wind. Although the current sensor outputs significant leaps in a measured sequence of directions, the interactive animations demonstrate that it is usable for such applications, if we could reduce the leaps to some degree.

This Paper describes the system configuration and implementation method of an IMPRES (Interactive Multimedia exPRESS) terminal. The terminal is developed in the form of a PC add-on board that is called MINIBA (Media and Network Interface Board Assembly). IMPRESS is a communication service platform that support various interactive multimedia services. The main objectives of developing IMPRESS are to implement DAVIC compliant services platform to verify DAVIC specification and to support testing environment. Currently IMPRESS terminal provides MPEG-2 quality movies on demand, switched video broadcasting, and home-shopping service to the service user, based on the ATM network.

In this paper, we propose a novel method for developing expressive typography authoring tools with personal emotions. Our goal is to implement an interactive typography system that does not rely on any particular language and provides an easy, natural user interface and allows for immediate interaction. For this purpose, we converted the text data entered by a user to image data. The image data was then used for interaction with the user. The data was synchronized with the user's skeleton information obtained from the depth camera. We decomposed the characters using the formality of language to provide a typographical movement that responds more dynamically to the user's motion. Thus, this system provides interaction as a unit of characters rather than as a whole character, allowing the user to have emotional and aesthetic emotional immersion into his or her creation.

본 연구는 변화하는 IT 환경에 따른 디자인 교육의 혁신 요구에 주목하여, 인터랙티브 디자인 분야의 학문적 가능성과 대학에서의 교육방안을 제시함으로서, 매체 및 기술의 변동에 따른 디자인 교육의 합리적인 방향성을 모색하였다. 본 연구는 사회적 요구에 따라 인터랙티브 디자인을 통한 고부가가치를 얻기 위해서는 그에 따른 연구와 학문적 기반이 갖추어져야 할 것이며, 특히, 대학에서의 독립적인 학문 영역 토대를 마련하고, 관련 교육과정의 구축이 선행되어야 할 것이라는 인식에 따라, 그 교육적 방향성을 제시하였다는데 의의가 있다. 본 연구를 통해 인터랙티브 디자인의 독자적 학문영역 구축의 필요성을 언급하였으며, 학문적으로 인터랙티브 디자인의 개념과 범위를 정립하였다. 인터랙티브 디자인학의 영역은 전통적인 기술만을 가르치는 것으로는 충분하지 않다. 따라서 전통적 디자인 교육의 보편적 한계를 넘어선 기술적 이해를 요구하면서, 복합적인 이슈를 다룰 수 있어야 할 것이며, 그에 따른 차별화된 교육방법의 모색이 요구된다.

향수자 일방의 관조적인 관람을 전제로 하는 작품 창작의 주류 속에서 관람자 참여의 문제가 본격적으로 대두된 것은 20세기 예술에서였다. 수동적 관람자로부터 능동적 참여를 끌어낸 옵아트나 키네틱아트 등은 향후 전개될 인터랙티브 아트의 견인차 역할을 했다. 작가와 관람자의 상호대면을 포맷화하는 '해프닝' 장르 등의 작업들도 TV나 아날로그 매체를 통한 관람자와의 소통 양식들을 적극적으로 끌어들이게 된다. 이후 컴퓨터를 이용한 디지털 매체가 본격적으로 등장하면서 관람자와 인터랙티브 아트의 상호소통을 통한 작품의 창작은 결정적 전기를 맞게 된다. 본 논문은 예술 사조사에서 인터랙티브아트의 생성과 전개의 맥락을 전형화하는 대표적 작품들의 사례 분석을 통해 인터랙티브 아트의 발전적 흐름을 고찰하고자 한다.

In Ubiquitous era. architecture is not the old building adapting ubiquitous technology. In order to take the role as new architectural paradigm in space, environment and technology, it has to develop technology continuously and experimental architecture at the same time. it must have co-evolution of architectural field and others through organic network. by that, the evolution of space will be in the way that combines space which is responded to human emotion and user-centric human-friendly. It will be the new paradigm of Ubiquitous digital space. Digital technology resulted in a change to a society as well as to the life of human and its way of thinking. Due to those changes, new terms or concepts come out and a new meaning is added to the conventional concepts. This aims to examine type of spatial contexts for interaction design experience. This study is performed through Literature research for theory by interactive space and case studies for construction elements to design. The range of case study is limited to interaction space in addition of interactive elements and user interface. And analysis conclusion is show the many type, First, Interactive space has special purpose for make a interaction by intelligent elements.(sensor, program, algorithm, New-technology) Second, Interactive space was cooperation with various professional for space purpose. Third. Interactive space is self-develop by algorithm, program, sensor network and that is harmonize with user. finally. Interaction space is show the temper elements about allness, metastatic, activeness, liquidity, relationship. That was written by ecological theory.

Designing a user interface is important because the user interface determines the level of physical and mental engagement of the user resulting in their level of learning. This paper investigated how physical engagement through a different user interfaces is associated with fun and learning and presented a theoretical physical engagement model called, PEM, developed based on an empirical user study. The PEM model describes how a game user interface is associated with the level of fun and learning, particularly in playing a full body engaged game. There are many different types of games but the Wii Tennis, an embodied interactive game, was chosen as an instance of full body engaged game. A user study with 32 participant's age ranged from 21 to 40 years old revealed that there is a positive correlation between both fun and learning and the level of physical engagement through two different user interfaces. The results of the study showed that the extent of fun and learning are associated with the physical engagement of the player through an interface. As an implication from the study, the result recommend that the level of user engagement is realized by an effective user interface, and the level of physical engagement is determined by the level of authenticity bridged by the user interface.
