User- and task-centred virtual model for product development with regard to further life phases, actors and environments

产品开发和制造公司通过提高创新频率（导致产品生命周期缩短）和增加可变性的更复杂产品来应对日益激烈的全球竞争。这对产品开发过程提出了新的和扩展的挑战。为了应对这些挑战，越来越多的数字化模型和方法被应用于虚拟产品开发中。这些应尽可能早地为虚拟产品开发的参与者提供有关产品、其行为及其生命阶段的详细信息。为了将这种类型的信息快速并以演示的方式呈现给异构开发团队，使用了虚拟现实（VR）等新技术。今天，数字方法和工具的开发和评估几乎完全集中在产品及其行为的正确建模上。然而，除了这些方面之外，在产品的每个生命阶段中，由人类和环境组成的背景也起着重要的作用。到目前为止，产品模型，产品行为，产品生命阶段，人类和环境的背景和-由此产生的-用户和任务为中心的方法和工具在虚拟环境中的关系还没有得到系统的研究。这些关系是这里提出的项目的重点。要实现以下目标：1。开发支持产品开发的扩展VR模型的一般描述。除了产品描述符之外，它还包括“参与者”和“环境”组件，然后才定义实现要求。2.根据第1条，制定用户界面创建指南，使用户和任务导向的交互与扩展的VR模型相结合。

Product developing and manufacturing companies react on the increasing global competition by raising innovation frequencies - resulting in shorter product life-cycles - and by more complex products with enhanced variability. This poses new and extended challenges on the product development process. In order to meet these challenges, more and more digital models and methods are applied in (virtual product development). These shall provide actors in virtual product development with detailed information about the product, its behaviour and its life-phases as early as possible. In order to present this type of information to heterogeneous development teams quickly and in a demonstrative way, new technologies such as Virtual Reality (VR) are utilised. Today, the development and evaluation of digital methods and tools almost entirely focus on a proper modelling of the product and its behaviour. However, in addition to these aspects the context consisting of humans and environment in each life-phase of the product plays an important role. So far, the relations between product model, product behaviour, product life-phases, the context of humans and environment and - resulting from that - user- and task-centred methods and tools in virtual environments have not been investigated systematically. These relations are the focus of the project proposed here. The following objectives are to be achieved: 1. Development of a general description for an extended VR-model supporting product development. In addition to product descriptors, this consists of the components "actor" and "environment" and only then defines requirements of implementation. 2. Development of guidelines for the creation of user interfaces that enable user- and task-oriented interactions with extended VR-models according to no. 1.
