论文摘要
在这项工作中，我们解决了文化遗产对象的虚拟代表触觉互动的问题。我们的主要重点是向不同能力的人提供对任何物理规模的艺术对象的触觉访问。这是一个低成本的系统，并与立体视觉展示结合使用，甚至为视力人士提供了更好的身临其境体验。为了实现这一目标，我们为点云数据提出了一种简单的多级，基于代理的触觉渲染技术，其中包括备受疑问的可伸缩性功能，使用户能够在触觉交互过程中自适应地改变对象的规模。对于拟议的触觉渲染技术，代理更新循环以比1kHz所需的触觉更新频率快100倍。我们观察到，这种功能随着经验的现实主义而很好地增强了。
In this work, we address the issue of a virtual representation of objects of cultural heritage for haptic interaction. Our main focus is to provide haptic access to artistic objects of any physical scale to the differently-abled people. This is a low-cost system and, in conjunction with a stereoscopic visual display, gives a better immersive experience even to the sighted persons. To achieve this, we propose a simple multilevel, proxy-based hapto-visual rendering technique for point cloud data, which includes the much-desired scalability feature which enables the users to change the scale of the objects adaptively during the haptic interaction. For the proposed haptic rendering technique, the proxy updation loop runs at a rate 100 times faster than the required haptic updation frequency of 1KHz. We observe that this functionality augments very well with the realism of the experience.
