在估计真实的世界中物体的距离或大小时,我们经常使用自己的身体作为度量;这种策略称为基于身体的缩放。然而,由于技术限制,例如与人的真实的身体相比时虚拟身体的窄视场和低保真度,经由头戴式显示器呈现的虚拟环境中的对象大小估计不同于物理世界。我们专注于提高逼真度的参与者的身体表示在虚拟环境中与个性化的手使用个性化的特点和视觉忠实增强虚拟化方法。为了研究个性化手的影响,我们将其与通用虚拟手进行了比较,并测量了对虚拟身体所有权、空间存在和对象大小估计的影响。具体来说,我们要求参与者执行一项感知匹配任务,该任务基于缩放他们面前桌子上的虚拟盒子。我们的研究结果表明,个性化的手不仅增加了虚拟身体的所有权和空间存在,而且还支持参与者正确估计他们的手附近的虚拟对象的大小。
When estimating the distance or size of an object in the real world, we often use our own body as a metric; this strategy is called body-based scaling. However, object size estimation in a virtual environment presented via a head-mounted display differs from the physical world due to technical limitations such as narrow field of view and low fidelity of the virtual body when compared to one's real body.In this paper, we focus on increasing the fidelity of a participant's body representation in virtual environments with a personalized hand using personalized characteristics and a visually faithful augmented virtuality approach. To investigate the impact of the personalized hand, we compared it against a generic virtual hand and measured effects on virtual body ownership, spatial presence, and object size estimation. Specifically, we asked participants to perform a perceptual matching task that was based on scaling a virtual box on a table in front of them. Our results show that the personalized hand not only increased virtual body ownership and spatial presence, but also supported participants in correctly estimating the size of a virtual object in the proximity of their hand.
