  • The functional behavior of a portable consumer electronic (PCE) product is nearly all expressed with human-machine interaction (HMI) tasks. Although physical prototyping and computer aided design (CAD) software can show the appearance of the product, they cannot properly reflect its functional behavior. In this paper, we propose a virtual prototyping (VP) system that incorporates virtual reality and HMI functional simulation in order to enables users to capture not only the realistic look of a PCE product but also its functional behavior. We obtain geometric part models of the product and their assembly and kinematics information with the help of CAD and reverse engineering tools, and visualize them with various display tools. We adopt state transition methodology to capture the HMI functional behavior of the product into a state transition chart, which is later used to construct a finite state machine (FSM) for the functional simulation of the product. The FSM plays an important role to control the transition between states of the product. The proposed VP system receives input events such as mouse clicks on buttons and switches of the virtual prototype model, and it reacts to the events based on the FSM by activating associated activities. The VP system provides the realistic visualization of the product and the vivid simulation of its functional behavior. It can easily allow users to perform functional evaluation and usability testing. Moreover, it can greatly reduce communication errors occurring in a typical product development process. A case study about VP of an MP3 player is given to show the usefulness of the proposed VP system.

  • The importance of service industries is growing as the portion of the service sector increases fast in the recent decades. This research deals with service prototyping and testing in a service laboratory. While products are generally tested through prototyping in new product development processes, services are difficult to test because of the characteristic of service, intangibility. A service laboratory, named s-Scape, is the experiment environment which has been developed to test services in virtual space for the purpose of analysis and improvement of real-world services such as hospitals and automobile show rooms. In this research, we present a service prototyping tool and language to support service test in the service laboratory. We first analyze key elements of service prototypes, and then design the service prototype diagram (SPD) and the service prototype description language (SPDL). SPD, which is a variant of the service blueprint, is a graphical tool to be used to generate SPDL. SPDL is an executable language of describing a service prototype of a real-world service in extensible markup language (XML) to experiment the service environment in virtual space. SPD reflects the control and interface of virtual reality devices, as well as key elements of service modeling. SPD represents a service process in which service providers and customers interact with each other in a service scape.

  • Today's product development requires simultaneous satisfaction of low cost, high quality and fast time to market. It is, however, difficult for product designers and engineers to achieve this goal due to too many requirements. This study shows integrated Computer Aided Engineering (CAE) approach can help to achieve such goal. CAE can not only support designers when decision needs to be made during concept design period but also provide evaluation of the designed parts and guidance to the best design of products during detail design period. Furthermore, integration with virtual prototyping concept can reduce number of actual prototyping and consequently reduce product development cost and time considerably. In order to demonstrate its possibility, example of washing machine development using CAE and its results are presented in this study.

  • As the need for more variety of interactive media grows, alternative interaction methods beyond conventional ones such as mice and keyboards are vigorously explored recently. In particular, these new approaches are getting attentions because they can enhance the user experiences in the interaction. Howerver, since they are case-dependent and specific, it still becomes crucial to consider and evaluate the effects and possibilities of interactions. The study aims to explore the ways to design the interactions by applying Behavioral Prototyping Methods in the initial stage of design development, which it calls 'Interactive Prototyping Method'. With the case project, 'Shadow Theater', which is an interactive installation for children, children can play and participate in interactive story-making by wearing hand puppets, casting shadows of hand puppets, and interacting with virtual objects on screen. To explore and design the interactions of Shadow Theater at the initial design process, the study builds an interactive prototype which borrows puppet theater settings and lets children play with hand puppets and other objects. The session of user try-outs with the prototype help to understand what and how they interact with virtual objects, and to improve the interactions.

  • We present a use. interface(UI) simulator for developing a mobile phone. This simulator consists of 3 major modules: Graphic Tool Editor, User Interface Software(UI), and Network Command Processor(NCP). The Graphic Tool Editor can design a virtual mobile terminal. The NCP sends a command to the phone and then receives its status from the phone after completion of the command. We can add or modify lots of features easily to the phone using the UI module. These modules can interact each other by sharing the common area in the memory. By doing so, these modules can exchange their status and data to operate in real-time. We have designed and tested a virtual prototyping phone for the LGP 3200 manufactured by LGIC by using the simulator. Through a series of experiment, we have believed that our virtual prototyping interactive simulator can do shorten its development and testing cycle by applying it in the early design phase.

  • The process equipment for handling high level radioactive materials like spent fuels is operated in a hot cell, due to high radioactivity. Thus, this equipment should be maintained and repaired optimally by a remotely operated manipulator. The master-slave manipulators(MSM) are widely used as a remote handling device in the hot cell. The equipment in the hot cell should be optimally placed within the workspace of the wall-mounted slave manipulator for the maintenance operation. But, because of the complexity in the hot cell, there would be some parts of the equipment that are not reached by the MSM. In this study, the maintenance process for these parts of the equipment is developed using virtual prototyping technology. To analyze the workspace of the maintenance device in the hot cell and to develop the maintenance processes for the process equipment, the virtual mock-up of the hot cell for the spent fuel handling process is implemented using IGRIP. For the implementation of the virtual mock-up, the parts of the equipment and maintenance devices such as the MSM and servo manipulator are modeled and assembled in 3-D graphics, and the appropriate kinematics are assigned. Also, the virtual workcell of the spent fuel management process is implemented in the graphical environment, which is the same as the real environment. Using this mock-up, the workspace of the manipulators in the hot cell and the operator's view through the wall-mounted lead glass are analyzed. Also, for the dedicated maintenance operation, the analyses for the detailed area of the end effectors in accordance with the slave manipulator's position and orientation are carried out. The parts of the equipment that are located outside of the MSM's workspace are specified and the maintenance process of the parts using the servo manipulator that is mounted in the hot cell is proposed. To monitor the process in the hot cell remotely, the virtual display system by a virtual camera in the virtual work cell is also proposed. And the graphic simulation using a virtual mock-up is performed to verify the proposed maintenance process. The maintenance process proposed in this study can be effectively used in the real hot cell operation and the implemented virtual mock-up can be used for analyzing the various hot cell operations and enhancing the reliability and safety of the spent fuel management.

  • In the virtual prototyping (VP) of digital products, it is important to provide the people involved in product development with the visualization and interaction of the products, and the simulation of their human machine interaction (HMI) behaviors in interactive 3D virtual environments. Especially, for the HMI behavior simulation, it is necessary to represent them properly and to play them back effectively according to user interaction in the virtual environments. In a conventional approach to HMI behavior simulation, user interface (UI) designers use UI design software tools to generate the HMI behavior of a digital product of interest. Due to lack of reusability of the HMI behavior, VP developers need to analyze and integrate it into a VP system for its simulation in a 3D virtual environment. As this approach hinders the effective communication between the UI designers and the VP developers, it is easy to create errors and thereby it takes significant time and effort especially when it is required to represent the HMI behavior to the finest level of detail. In order to overcome the shortcomings of the conventional approach, we propose an approach for representing the HMI behavior of a digital product using XML (eXtensible Markup Language) and for reusing it to perform the HMI behavior simulation in 3D virtual environments. Based on the approach, a VP system has been developed and applied for the design evaluation of various products. A case study about the design evaluation is given to show the usefulness of the proposed approach.
