Risk Assessment Using Virtual Reality

项目摘要

The planned Virtual Reality (VR)-based risk assessment method will allow conducting full risk assessments (RA) based solely on digital data at a very early stage in the product development process. In this context it is conjecturable that by using VR the influence of subjective experience will become more important as it already is for the conventional risk assessment. Therefore the evaluation of the influences of subjective experience when conducting a VR-based RA is the primary goal of the project.Therefore it is necessary to develop a method for the VR-based RA. As part of this method, concepts for the creation of the VR model, for the interaction with the VR environment as well as for the integration and usage of additional information have to be established. The main focus regarding the creation of the VR models are the data conversion from CAD to VR and the visualization of hazard factors (HF). After developing those concepts mentioned above, an instruction for the conduction of the VR-based RA has to be created.In parallel, survey questionnaires will be developed based on existing knowledge on perception of technical objects in virtual environments. Aspects like more complex visualization contents as well as the project focus on recognizing HF have to be considered. In addition it is necessary to combine merely psychological survey questionnaires, i.e. questionnaires that measure the risk tendency of the test person, with questionnaires that measure the sense of presence and account for object characteristics of the visualization. Those survey questionnaires will be used in user tests to evaluate aspects of perception, i.e. recognition and assessment of HF in VR. Furthermore tests will be conducted to assess the influence of the sense of presence as well as the impact of individual personality traits on the quality of the RA. Participants will be experts in RA (Industrial Safety Specialists, Designers) and will be asked to execute a VR-supported RA inside a 5-sided CAVE using the predefined methods.To deepen the knowledge about the influence of subjective experience, a second research aspect, the visualization of hazardous situations, is added. Here, the user tests target the evaluation of behavioral reactions in different hazardous situations. Thus a method to simulate and visualize such hazardous situations has to be developed and corresponding survey instruments have to be created.The results from both user tests will be used to improve the method of VR-supported risk assessment. In addition possible reasons for perception differences between reality and virtual reality will be evinced.

计划中的基于虚拟现实（VR）的风险评估方法将允许在产品开发过程的早期阶段仅基于数字数据进行全面的风险评估（RA）。在这种情况下，可以肯定的是，通过使用VR，主观经验的影响将变得更加重要，因为它已经是传统的风险评估。因此，在进行基于虚拟现实的RA时，主观体验的影响评估是本项目的主要目标，因此有必要开发一种基于虚拟现实的RA方法。作为该方法的一部分，必须建立用于创建VR模型、用于与VR环境交互以及用于集成和使用附加信息的概念。关于VR模型的创建，主要关注的是从CAD到VR的数据转换和危险因素（HF）的可视化。在开发上述概念后，必须创建用于进行基于VR的RA的指令。同时，将根据虚拟环境中技术对象感知的现有知识开发调查问卷。必须考虑更复杂的可视化内容以及重点识别HF的项目等方面。此外，有必要将仅心理调查问卷（即测量测试人员的风险倾向的问卷）与测量存在感并说明可视化的对象特征的问卷联合收割机组合。这些调查问卷将用于用户测试，以评价感知方面，即VR中HF的识别和评估。此外，将进行测试，以评估存在感的影响，以及个人的人格特质对RA质量的影响。参加者是RA（Industrial Safety Specialists，Designers）领域的专家，将被要求使用预定义的方法在5面CAVE内执行VR支持的RA。为了加深对主观体验影响的认识，增加了第二个研究方面，即危险情况的可视化。这里，用户测试的目标是评估不同危险情况下的行为反应。因此，必须开发一种模拟和可视化这种危险情况的方法，并创建相应的调查工具。用户测试的结果将用于改进VR支持的风险评估方法。此外，可能的原因感知现实和虚拟现实之间的差异将被证明。
