被动触觉学习（PHL）是在不主动关注学习的情况下获得感觉运动技能。一种方法是在用户专注于另一项主要任务时，使用可穿戴触觉界面提供的振动提示来“教授”运动技能。我们创建了一个用于打字技能被动触觉学习的系统。在一项包含 16 名参与者的研究中，与对照组相比，接受被动指令的用户在盲文中输入短语的错误显着减少（平均错误率下降 32.85%，而错误率平均增加 2.73%）。 PHL 用户还能够识别并阅读该短语中更多的盲文字母（72.5% vs. 22.4%）。在第二项研究中，迄今为止已有 8 名参与者，我们在四节课中被动地教授完整的盲文字母表。接受 PHL 的参与者的打字错误减少速度更快、更一致，75% 的 PHL 用户与 0% 的对照组用户实现了零打字错误。到研究结束时，PHL 参与者还能够识别并阅读 93.3% 的盲文字母。这些结果表明，可穿戴计算机促进的被动触觉教学可能是教授盲文打字和阅读的可行方法。
Passive Haptic Learning (PHL) is the acquisition of sensorimotor skills without active attention to learning. One method is to "teach" motor skills using vibration cues delivered by a wearable, tactile interface while the user is focusing on another, primary task. We have created a system for Passive Haptic Learning of typing skills. In a study containing 16 participants, users demonstrated significantly reduced error typing a phrase in Braille after receiving passive instruction versus control (32.85% average decline in error vs. 2.73% increase in error). PHL users were also able to recognize and read more Braille letters from the phrase (72.5% vs. 22.4%). In a second study, containing 8 participants thus far, we passively teach the full Braille alphabet over four sessions. Typing error reductions in participants receiving PHL were more rapid and consistent, with 75% of PHL vs. 0% of control users reaching zero typing error. By the end of the study, PHL participants were also able to recognize and read 93.3% of all Braille alphabet letters. These results suggest that Passive Haptic instruction facilitated by wearable computers may be a feasible method of teaching Braille typing and reading.
