Virtual Reality based driving simulators are increasingly used to train and assess users' abilities to operate vehicles in a controlled and safe way. For the development of those simulators it is important to identify and evaluate design factors affecting perception, behaviour, and driving performance. In an exemplary power wheelchair simulator setting we identified the three immersion factors display type (head-mounted display v monitor), ability to freely change the field of view (FOV), and the visualisation of the user's avatar as potentially affecting perception and behaviour. In a study with 72 participants we found all three factors affected the participants' sense of presence in the virtual environment. In particular the display type significantly affected both perceptual and behavioural measures whereas FOV only affected behavioural measures. Our findings could guide future Virtual Reality simulator designers to evoke targeted user behaviours and perceptions.
基于虚拟现实的驾驶模拟器越来越多地用于以可控且安全的方式训练和评估用户操作车辆的能力。对于这些模拟器的开发而言，识别和评估影响感知、行为及驾驶性能的设计因素至关重要。在一个示例性的电动轮椅模拟器设置中，我们确定了三个沉浸因素：显示类型（头戴式显示器与显示器）、自由改变视野（FOV）的能力以及用户虚拟形象的可视化，这些因素可能会影响感知和行为。在一项有72名参与者的研究中，我们发现这三个因素均影响了参与者在虚拟环境中的临场感。特别是显示类型显著影响了感知和行为指标，而视野仅影响行为指标。我们的研究结果可为未来虚拟现实模拟器设计者提供指导，以引发有针对性的用户行为和感知。
