The invention discloses a tactile transmission method for identifying virtual keys on the intelligent surface of a cockpit, which comprises the following steps: acquiring the pressure of pressing the virtual keys through a pressure sensor, realizing a key function and providing normal response feedback when the pressure is heavy, and helping a user to identify the keys only through a tactile transmission method when the pressure is light, comprising the steps of 1, constructing a group of stimulation signals, presenting the stimulation signals to a user in pairs for subjective difference scoring, and obtaining a comparison distance matrix of each pair of stimulation; step 2, calculating a stimulation two-dimensional coordinate matrix after dimension reduction through a multi-dimensional scaling algorithm; 3, when the stimuli in the two-dimensional diagram are uniformly distributed, the difference sum of a set M with m stimuli is maximum, and the distance between each stimulation pair in the set is greater than the standard deviation, determining that the set of stimuli is the highest distinguishable stimulation set; and when the stimulation set meeting the condition does not exist in the graph, adding a new stimulation signal into the step 1, comparing with stimulation, and repeating the steps 2 and 3.
本发明公开了一种用于识别座舱智能表面虚拟按键的触觉传输方法,包括:通过压力传感器获取按动虚拟按键的压力,重压时实现按键功能且提供正常响应反馈,轻压时仅通过触觉传输方法帮助用户识别按键,包括:步骤一、构造一组刺激信号,将刺激信号两两呈现给用户进行主观差异评分,获得每对刺激的比较距离矩阵;步骤二、通过多维缩放算法计算出降维后的刺激二维坐标矩阵;步骤三、当二维图各刺激分布均匀,存在一组具有m个刺激的集合M差异和最大,并且集合中各个刺激对之间的距离均大于标准偏差,则确定这组刺激为最高可辨别性的刺激集合;当图中不存在符合条件的刺激集合时,则向步骤一中增加新的刺激信号,并与有刺激进行比较,重复步骤二和三。
