【摘要】：本文设计了一个回忆性实验和一个再认性实验,使用自行研制的振动触觉表达装置作为实验平台,研究了人手腕部的振动强度触觉感知短时记忆特性。首先通过回忆性实验确定了人手腕部的振动强度触觉感知平均记忆容量(简称振动强度记忆容量),然后在记忆容量范围内又进行了再认性实验,对人手腕部的振动触觉再认正确率和反应时进行了数据分析。通过实验,我们得到人手腕部振动强度触觉感知相关的5个重要特性:(1)振动强度记忆容量为3±1;(2)振动触觉刺激的振动强度离散间隔越大,振动强度记忆容量就越大;(3)振动强度记忆容量具有显著的性别差异;(4)振动触觉短时记忆信息的提取是逐个比较的遍历扫描过程;(5)触觉感知再认正确率和反应时表现均远逊于视觉和听觉。这些实验结果有助于充分了解人体的触觉感知特性,是振动触觉表达编码方案的重要设计依据。
[Abstract]:In this paper, a recall experiment and a recognition experiment are designed. Using the self-developed vibratory tactile expression device as the experimental platform, the short-time memory characteristics of the vibration intensity tactile perception of the hand wrist are studied. First of all, the average memory capacity of vibration intensity tactile perception (called vibratory intensity memory capacity) was determined by recall experiment, and then the recognition experiment was carried out in the range of memory capacity. The accuracy rate and response time of vibration tactile recognition in human wrist were analyzed. Through experiments, we obtained five important characteristics related to tactile perception of hand wrist vibration intensity: (1) the memory capacity of vibration intensity is 3 卤1; (2) the larger the dispersion interval of vibration intensity, the larger the memory capacity of vibration intensity, (3) the greater the memory capacity of vibration intensity is. (4) the extraction of vibratory tactile short-term memory information is a traversal scanning process, and (5) the recognition accuracy and response time of tactile perception are much worse than those of vision and hearing. These experimental results are helpful to fully understand the tactile perception characteristics of human body and are an important basis for the design of vibratory tactile expression coding scheme.
