利用幅度调制将低频振动呈现于面部
摘要
本研究提出一种方法，用于向面部呈现纯低频振动感，这种感受无法通过小型商业可用振动器实现。核心创新在于采用约200 Hz的载波频率进行幅度调制。由于面部区域不存在颗粒神经节——负责检测约200 Hz高频振动的受体器——因此仅感知到原始的低频信号。 conducted three experiments. Experiments 1 and 2 were performed on the forehead to confirm that the proposed amplitude modulation method could produce the desired low-frequency perception and to evaluate the subjective quality of the vibration. The results suggested that the proposed method could produce the perception of desired pure low-frequency vibration when applied to the forehead. In Experiment 3, the proposed method was applied to the whole face, and its range of applicability was explored. The results indicated that the original low-frequency vibration was clearly perceptible around the eyes, cheeks, and lower lip area.
