| 目的 在预警场景下应用振动触觉传递警报信号以弥补受损的感觉通道，探索头戴振动设备的合理形式，从而为头戴振动设备的工业设计提供指导。方法 围绕空间分布位置、时间和振动参数设置实验，研究振动触觉的特征，提出一种振动触觉系统。在实验一中，对头部进行触觉感知性测量以比较不同位置的灵敏性，确定振动作用于头部的适宜部位。在实验二中，组合不同的时间模式以及强弱程度形成7种振动模式，通过比较得出适于传达警报信息的触觉模式。基于实验结论，设计出一款应用于建筑工地场景下的工程预警头盔。结果 前额无毛区域与颞部中央区域感受性最灵敏;时间间隔短、强度高的振动模式更适于传达警报信息。结论 感知实验的结论为振动组件的布置和振动警报模式的参数设定提供了依据，并有效地被运用于针对具体场景的头戴设备设计中。 |

| This study aims tocompensate for impaired sensory channels through vibrotactile warning signals and explore ideal forms of head-mounted vibrotactile devices to provide guidelines for industrial design. In order to study features of vibration, experiments in this study focused on the spatial locations, temporal patterns and parameters of vibrotactile stimuli, and proposed a vibrotactile early warning system. In the first experiment, measurements of tactile perception were conducted to assess the sensitivity of different positions on the head to identify suitable vibration positions. In the second experiment, seven vibrotactile patterns composed of different temporal patterns and intensities were compared to identify suitable warning patterns. Based on experiments, a vibrotactile warning helmet was designed to be used in construction sites. The results showed that the hairless region around the forehead and the center of the temporal regions have higher sensitivity, and those vibrotactile patterns with short intervals and high intensity are more suitable for transmitting warning information. These results from perceptual experiments provided evidence for placing vibration modules and determining parameters of vibrotactile stimuli, which can be applied to the design of head-mounted devices based on a specific situation. |
