由于虚拟现实(VR)内容的传播，可以使用的化身变得更加多样化。关于化身对用户的影响，已经进行了几项研究。关于头像形状对物体大小知觉和头像归属感的影响的研究一直很有限，但对头像形状知觉的影响还没有被研究。关于视觉效应的研究表明，瞳孔间距离(IPD)影响物体大小知觉和距离知觉。也有报道称，降低摄像头高度和缩短IPD可以让周围的空间看起来更大。这表明IPD可能会影响化身的形状知觉和拥有感。在这项研究中，我们专注于改变化身和IPD的形状。我们准备了与参与者身体形状相似的化身和具有极长/极短肢体的化身。然后，我们通过基于三个IPD(短、正常和长)之一来操作准备好的化身，检查了化身的形状感知和所有权意识的变化。研究结果证实，手臂和腿的长度和IPD可能会影响手臂和腿的长度和厚度的知觉以及化身的归属感。
Owing to the spread of virtual reality (VR) content, avatars that can be used have become more diverse. Several studies have been conducted on the effects of avatars on users. The investigation on the effects of avatar shape on the perception of object size and the sense of ownership of the avatar has been limited; however the effects on the perception of the avatar’s shape have not been investigated. Studies focusing on visual effects have reported that the interpupillary distance (IPD) influences object-size perception and distance perception. It has also been reported that lowering the height of the camera and shortening the IPD can make the surrounding space seem larger. This suggests that the IPD may affect the shape perception and the sense of ownership of avatars. In this study, we focused on changing both the shape of the avatar and the IPD. We prepared avatars with a shape similar to that of the participant's body and avatars with extremely long/short limbs. Then, we examined the changes in the shape perception and the sense of ownership of the avatar by manipulating the prepared avatar based on one of the three IPDs (short, normal, and long). The results confirmed that the length of arms and legs and IPD may affect the perception of length and thickness of arms and legs and the sense of ownership of avatars.
