Abstract

We have developed an interactive 4-D visualization system that employed the principal vanishing points operation as a method to control the movement of the eye-point and the change in the viewing direction in 4-D space. Different from conventional 4-D visualization and interaction techniques, the system can provide intuitive observation of 4-D space and objects by projecting them onto 3D space in real time from various positions and directions in 4-D space. Our next challenge is to examine whether humans are able to develop a spatial perception of 4-D space and objects through 4-D experiences provided by the system. In this paper, as the first step toward our aim, we assessed whether participants were able to get intuitive spatial understanding of 4-D objects. In the evaluation experiment, firstly, the participants learned a structure of a hypercube. Then, we evaluated their spatial perception developed in the learning period by tasks of controlling the 4-D eye-point and reconstructing the hypercube from a set of its 3-D projection drawings. The results indicated evidence for that humans were able to get 4-D spatial perception by operating the system.

利用三维屏幕交互可视化系统,通过超立方体识别任务建立四维空间感知
我们开发了一个交互式的四维可视化系统,该系统采用主消失点操作作为一种方法来控制眼球在四维空间中的移动和观看方向的变化。与传统的四维可视化和交互技术不同,该系统可以将四维空间和物体从四维空间的不同位置和方向实时投影到三维空间中,提供对四维空间和物体的直观观察。我们的下一个挑战是检查人类是否能够通过系统提供的4-D体验来发展对4-D空间和物体的空间感知。在本文中,作为我们目标的第一步,我们评估了参与者是否能够对4-D物体有直观的空间理解。在评价实验中,首先,参与者学习了一个超立方体的结构。然后,我们通过控制四维视点和从一组三维投影图重建超立方体的任务来评估他们在学习期间发展的空间感知。结果表明,人类能够通过操作该系统获得四维空间感知。
