虚拟现实建筑场景中距离认知还原度研究
|
摘要
随着虚拟现实技术的日臻成熟与普及,在建筑设计等领域,虚拟现实技术为使用者提供了体验和感知未建成空间的机会,使设计实现在虚拟空间中。然而虚拟现实技术对空间尺度的还原度会影响人们在虚拟空间中的感知,进而影响设计效果。本研究以Oculus Rift DK2虚拟现实设备为平台,建立室内空间虚拟场景并与现实场景进行对比试验,收集被试在两种场景中水平距离判断的数据进行分析,寻找距离判断的差异性,提出建筑场景距离感知优化方法及修正公式。
With the development and popularity of virtual reality technology, it offers an opportunity for designers and users to experience un-built spaces in areas such as architectural design, making design realized in 3D space. However, the revivification degree of virtual reality on the spatial scale will affect people's perception in the virtual space, and then affect the impression of design and audience cognition. In this study, a virtual scene of the indoor space was established in the Oculus Rift DK2 virtual reality equipment comparing with the actual scene. Collecting the horizontal distance estimate data of volunteer subjects in the both virtual scene and the actual scene. Through Analyzing statistical methods and find the difference of people's judgment in this two kinds of space scale, Evaluating he simulation ability of Vizard virtual reality engine's spatial scale, Proposing a better method of scale cognition and correction coefficient in virtual reality scene.
