通过皮肤进行自然语言的交流使移动设备和可穿戴技术的出现引起了人们的兴趣。对候选触觉编码算法的有效评估仍然是一个重大挑战。我们提出了4种算法以及我们的评估方法，这些算法基于可区分性，可学习性和可推广性。有利地，不需要掌握广泛的词汇。触觉显示器使用了16或32个曲折的执行器，线性地排列或手臂上的网格。在研究1中，一种两种强制选择方案测试了10位参与者检测由3种声学算法编码的单词对差异的能力：频率分解（FD），显性光谱峰（DSP）（DSP）和自动编码器（AE）。在算法中，检测特异性没有差异，但是AE的灵敏度明显差于FD或DSP。研究2使用自定义视频游戏进行培训和测试，将16名参与者与DSP与基于音素的算法（pH）进行了比较。 pH组在所有测试阶段表现出色，并显示出对单词的更好识别和保留以及对新单词的普遍性的证据。
Communication of natural language via the skin has seen renewed interest with the advent of mobile devices and wearable technology. Efficient evaluation of candidate haptic encoding algorithms remains a significant challenge. We present 4 algorithms along with our methods for evaluation, which are based on discriminability, learnability, and generalizability. Advantageously, mastery of an extensive vocabulary is not required. Haptic displays used 16 or 32 vibrotactile actuators arranged linearly or as a grid on the arm. In Study 1, a two-alternative, forced-choice protocol tested the ability of 10 participants to detect differences in word pairs encoded by 3 acoustic algorithms: Frequency Decomposition (FD), Dominant Spectral Peaks (DSP), and Autoencoder (AE). Detection specificity was not different among the algorithms, but sensitivity was significantly worse with AE than with FD or DSP. Study 2 compared the performance of 16 participants randomized to DSP vs a phoneme-based algorithm (PH) using a custom video game for training and testing. The PH group performed significantly better at all test stages, and showed better recognition and retention of words along with evidence of generalizability to new words.
