This paper will explain the importance of using interactive prototyping tools in the HCI design process. The Future of HCI education project performed by ACM SIGCHI shows that students recognize that prototyping, especially paper prototyping and interactive prototyping, are both very important. Two widely-used prototyping tools in academy, Balsamiq and Oven, will be compared and rated by students according to their preferences. We choose the Balsamiq as our design tool because Oven can be designed on the web but applications cannot be designed directly on Mac or Windows. The Balsamiq tool will help you understand the task process of UI work and highlight the benefits of digital prototyping to test the execution of expected results in a fast fashion compared to high-level prototyping. We also present the outcome of this work through two case studies. In particular, the smart mirror project with voice recognition function shows the effectiveness of the proposed method as an example.

최근에 임베디드 시스템 개발자들을 위한 프로토타이핑 시스템 도구가 시장에 많이 출시되고 있다. 일찍부터 임베디드 시스템 설계에서 사용자의 요구사항을 분석하고 사용자 편의 인터페이스를 만드는데 있어서 프로토타입은 중요한 요소이다. 프로토타이핑 도구는 다음과 같이 Physical Prototyping (PP), Virtual Prototyping (VP), Modeling Prototyping (MP) 3가지로 나눌 수 있다. 이러한 프로토타이핑 기술을 통합하면 개발에 소모되는 비용내지 시간이 절약되므로써 시장진입시점이 빨라지고 제품의 경쟁력이 향상된다. 하지만 이러한 프로토타이핑을 통합하는데 있어서 여러가지 문제점이 존재한다. 본 논문에서는 여러 프로토타이핑 도구를 통합하는데 있어서 Javabean, ActiveX등과 같이 유연하고 재사용성이 용의한 컴포넌트를 이용하여 문제점을 해결하는 모습을 보여준다. 이러한 기술은 여러 임베디드 시스템을 개발시 재사용성과 유연성을 통한 편리성을 가질 수 있다.

To develop an effective virtual prototyping methodology for the PLC(Programmable Logic Controller) based real-time systems, a conversion algorithm from RLL(Relay Ladder Logic) to statechart is presented in this paper. The RLL is the main programming language to represent the operation of the PLC, and the statechart is the most widely used tool in the field of virtual prototyping in order to represent the behaviour of real-time systems. A virtual prototyping for an example case is implemened to evaluate the benefit of the proposed algorithm.

Internet technology opens up another domain for building future CAD/CAM environment. The environment will be global, network-centric, and spatially distributed. In this paper, we present a new approach to network-centric virtual prototyping (NetVP) in a distributed design environment. The presented approach combines the current virtual assembly modeling and analysis technique with distributed computing and communication technology fur supporting virtual prototyping activities over the network. This paper focuses on interoperability, shape representation, and geometric processing for distributed virtual prototyping. STEP standard and CORBA-based interfaces allow the bi-directional communication between the CAD model and virtual prototyping model, which makes it possible to solve the problems of interoperability, heterogeneity of platforms, and data sharing. STEP AP203 and AP214 are utilized as a means of transferring and sharing product models. In addition, Attributed Abstracted B-rep (AAB) is introduced as 3D shape abstraction for transparent and efficient transmission of 3D models and for the maintenance of naming consistency between CAD models and virtual prototyping models over the network.

The Rapid Prototyping and Tooling technology has been developed. However, most commercial ones currently use resins or waxes as the raw materials. These days. the direct metal deposition methods are researched as a true rapid prototyping and tooling technology. A fundamental study on rapid prototyping and tooling with wire welding technology using $CO_2$ laser radiation was carried out in this paper. The main focus is to develop a simple commercial rapid prototyping and tooling system with the exiting laser welding technology. The process is investigated as a function of laser parameters and process variables. Basic parts were fabricated as out-put and their microstructure, hardness and tensile strength are examined for the reliability. In addition, Its advantages and disadvantages are discussed as a rapid prototyping and tooling system.

가상 프로토타이핑 환경에서는 다양한 컴포넌트와 라이브러리를 제공함으로써 정밀한 단위까지의 목표 모델의 시뮬레이션이 가능하다. 그리고 실물 프로토타이핑 환경에서는 목표 모델의 임베디드 구동 환경에 가까운 시뮬레이션 환경을 제공한다. 하지만, 가상 프로토타이핑 환경에서는 실제 목표 모델의 구동 환경 요소까지의 시뮬레이션이 어렵고, 실물 프로토타이핑 환경에서는 다양하고 정밀한 제품까지의 시뮬레이션이 어려운 실정이다. 이런 가상과 실물 프로토타이핑 환경의 단점을 보완하기 위한 통합 프로토타이핑 시스템을 위한 연동 기법이 개발되었으며, 본 논문에서는 기존의 실물/가상 프로토타이핑 연동 기법을 개선해서 객체 기반의 임베디드 시스템 통합 프로토타이핑 개발 환경을 구축하였다. 이러한 새로운 임베디드 시스템 개발 환경을 구축함으로써, 재사용성, 유연성, 확장성 그리고 편리성을 가질 수 있다.

At present, the virtual prototyping technology for complex product is one of the research and application hotspots in current simulation technology. In authors viewpoint, the virtual prototype development for complex product has become a systematic engineering, which can be called the complex product virtual prototyping engineering (CPVPE). In this paper, the architecture, key technologies and its supporting environment of CPVPE are primary discussed firstly. Combined with the research project and primary practice undertaken by the authors, a typical application demonstration of the aerospace complex product virtual prototyping engineering (including mechanism, dynamics, software and control system) is also introduced based on the virtual prototype supporting environment developed by the authors. Finally, some further research works on CPVPE are also presented in this paper.

Rapid Prototyping(RP) techniques have revolutionized traditional manufacturing methods. These techniques allow the user to fabricate a part directly from a conceptual model before investing in production tooling and help develop new models with significant short time. This paper suggests to new process to manufacture large size hollow shape parts for prototype-car using Rapid Prototyping technology and Vacuum Molding with the reduction of delivery time. In addition, This paper introduces the dividing and combining method to make large size RP master model in spite of the limit of the build chamber dimensions of commercialized RP system and post-processing method to achieve sufficient surface quality.

In order to reduce the lead-time and cost, the technology of rapid prototyping(RP) has been widely used. This paper describes the methodology to fabricate a large object by using the principle of rapid prototyping. By laminating thick and sloping polystyrene foam plates, we can make the large model which has three dimensional, continuous surfaces faster and easier than conventional processes. Estimated error was much smaller than other RP products which have stepped effect. For accuracy improvement and post processing, machined metal plates are added between the thick plates. To keep the continuity of surface and strengthen the model, pilot holes and guide rods are applied. By the methodology described in this paper, a missile body with flush air intake was fabricated.
