Tactile transmission of information to prevent improper use or incorrect operation

讨论了使用触觉指示器和触觉反馈防止不当使用和错误操作的方法。至于触觉指标，有人试图提出触觉指标来分别识别饮料和毒品的种类。在触觉反馈方面，讨论了按钮开关的操作感受、操作对象和物理特性之间的关系。主要研究结果和发现总结如下：1)明确了用于识别饮料种类的触觉指示器的形状和材料。2)提出了以触觉指标来鉴别毒品种类的方法。此外，还提出了触觉指示器，以防止剂量错误。3)揭示了按钮开关的操作感受、操作对象和物理特性之间的关系。此外，还提出了时间因素在讨论按钮开关的操作感受时的重要性。

It was discussed methods to prevent improper use and incorrect operation using tactile indicators and tactile feedbacks. As for tactile indicators, it was tried to propose tactile indicators to identify the kinds of drink and drug, respectively. Regarding tactile feedbacks, it was discussed the relationships among operational feelings, operation objects, and physical characteristics of the push-button switches. Main results and findings were summarized as follows.1) It was clarified the shapes and materials for tactile indicator to identify the kind of drink. 2) The guideline of tactile indicator was proposed to indentify the kind of the drug. In addition, tactile indicators were proposed to prevent dosage error. 3) It was revealed that the relationships among operational feelings, operation object, and physical characteristics of the push-button switches. Moreover, it was suggested the importance of time factor to discuss operational feeling of the push-button switch.
