交互设计活动的展开需要在不同设计阶段制作原型对设计概念和设计方案进行验证。目前关于原型制作的理论和方法都只关注于软件界面设计,并没有从软硬件结合的交互系统层面对原型构建进行探讨。文章改进了David Benyon等人提出的PACT模型,提出了交互设计应该包括人、系统、情境三个方面的因素,进而说明了需要在交互设计过程中构建人物原型、系统原型、情境原型,并给出了原型构建所需的技术和方法。
The development of interactive design activities requires prototyping of design concepts and design scenarios at different stages of the design. At present, the theories and methods of prototyping focus only on the software interface design, and do not discuss the prototyping from the interactive system level of hardware and software integration. The paper improves the PACT model proposed by David Benyon et al. It proposes that interaction design should include three factors: people, system and situation, and then illustrates the need to build prototypes, system prototypes and situational prototypes in the process of interaction design. Out of the prototype building technology and methods required.
