XML을 이용한 3D 가상 제품의 HMI 행동양태 모델링과 시뮬레이션 방안

Abstract

Received 2 December 2014; received in revised form 8 January 2015; accepted 16 January 2015ABSTRACTIn the virtual prototyping (VP) of digital products, it is important to provide the people involvedin product development with the visualization and interaction of the products, and the simula-tion of their human machine interaction (HMI) behaviors in interactive 3D virtual environ-ments. Especially, for the HMI behavior simulation, it is necessary to represent them properlyand to play them back effectively according to user interaction in the virtual environments. In aconventional approach to HMI behavior simulation, user interface (UI) designers use UI designsoftware tools to generate the HMI behavior of a digital product of interest. Due to lack ofreusability of the HMI behavior, VP developers need to analyze and integrate it into a VP sys-tem for its simulation in a 3D virtual environment. As this approach hinders the effective com-munication between the UI designers and the VP developers, it is easy to create errors andthereby it takes significant time and effort especially when it is required to represent the HMIbehavior to the finest level of detail. In order to overcome the shortcomings of the conven-tional approach, we propose an approach for representing the HMI behavior of a digital prod-uct using XML (eXtensible Markup Language) and for reusing it to perform the HMI behaviorsimulation in 3D virtual environments. Based on the approach, a VP system has been devel-oped and applied for the design evaluation of various products. A case study about the designevaluation is given to show the usefulness of the proposed approach.Key Words: 3D Virtual Prototypes, HMI Behavior Modeling, HMI Behavior Simulation, VirtualPrototyping, XML
