Abstract

Quality evaluation is very important for haptic rendering. In this paper, an objective evaluation method for a haptic rendering system based on haptic perception features is proposed. In the method, the haptic rendering process is compared to the real world perception process in a simple standardized procedure based on feature extraction and data analysis. A complete evaluation process for a simple haptic rendering task of pressing a virtual spring is presented as an example to explain the method in detail. Compared with the traditional objective method based on error statistics, the method is more concerned about the consistency of human subjective feelings rather than physical parameters, which makes the evaluation process more consistent with the haptic perception mechanism. The results of comparative analysis show that the method presented in this paper is simple, gives reliable results reflecting the consistency with subjective feeling and has a better discrimination ability for different kinds of devices and algorithms compared with the traditional evaluation methods.
触觉渲染系统的客观质量评价方法——以硬度渲染为例
在触觉渲染中,质量评价是非常重要的。提出了一种基于触觉感知特征的触觉渲染系统客观评价方法。在该方法中,通过基于特征提取和数据分析的简单标准化过程,将触觉渲染过程与现实世界感知过程进行比较。一个完整的评估过程,一个简单的触觉渲染任务,按虚拟弹簧给出了一个例子,详细说明了该方法。与传统基于误差统计的客观评价方法相比,该方法更关注人的主观感受的一致性,而不是物理参数,使得评价过程更符合触觉感知机制。对比分析结果表明,本文方法简单,给出的结果可靠,反映了主观感受的一致性,与传统的评估方法相比,对不同类型的设备和算法具有更好的区分能力。
