摘要

主要贡献是实现一种有效的重定向工作(RDW)技术,利用触觉线索强烈地改变我们的空间感知。一些研究表明,用户可以在半径至少为22米的圆弧上重新定向,而不会通过在虚拟世界中显示一条直线路径来检测不一致。然而,这仍然太大,无法在有限的空间内展示演示。虽然大多数RDW技术只使用视觉刺激,但我们可以用多模态来识别空间。因此,我们提出了一种使用视觉-触觉交互的RDW方法,并开发了该系统,该系统显示平面墙壁的视觉表示,用户几乎沿着它直线行走,尽管在现实中,用户沿着凹凸表面的墙壁行走并触摸它。为了演示,我们开发了一种算法,该算法可以动态地修改变形量,使用户可以无限直地行走并自由地转动分支。有了这个系统,多个用户可以同时在一个虚拟的环境中行走一个没有尽头的走廊。

Unlimited corridor: redirected walking techniques using visuo haptic interaction
The main contribution is to realize an efficient redirected working (RDW) technique by utilizing haptic cues for strongly modifying our spatial perception. Some research has shown that users can be redirected on a circular arc with a radius of at least 22 m without being able to detect the inconsistency by showing a straight path in the virtual world. However, this is still too large to enable the presentation of a demonstration in a restricted space. Although most of RDW techniques only used visual stimuli, we recognize space with multi-modalities. Therefore, we propose an RDW method using the visuo-haptic interaction, and develop the system, which displays a visual representation of a flat wall and users virtually walk straight along it, although, in reality, users walk along a convex surface wall with touching it. For the demonstration, we develop the algorithm, with which we can modify the amount of distortion dynamically to make a user walk straight infinity and turn a branch freely. With this system, multiple users can walk an endless corridor in a virtual environment at the same time.
