情感触摸与中空超声:与真实物质的心理物理比较
IEEE transactions on haptics
|December 23, 2025
概括
使用聚焦超声波的中空触觉可以模仿皮肤上柔软的刷子的愉快感觉. 振幅调制增强了这种效果,使得超声波感觉更像是真实的纹理.
科学领域:
- 触觉和人机交互的人机交互
- 神经科学与感官感知
背景情况:
- 情感触摸对儿童发育和成年人的幸福有积极的影响.
- 通过缓慢轻轻的触摸来激活的C-触觉纤维是情感感觉的关键.
- 中空触觉提供了一种新的方式,可以在没有身体接触的情况下诱导触觉感觉.
研究的目的:
- 为了调查中空触觉是否可以复制毛发皮肤上柔软的刷子冲动的感知体验.
- 将空中超声波的触觉感知与各种现实世界的纹理进行比较.
- 确定振幅调制对空中触觉感知现实性的影响.
主要方法:
- 进行了一项心理物理研究,将空中超声波刺激与真实材料 (砂纸,树脂,,布,刷子) 的比较.
- 参与者对刺激进行了评分,分别是愉快,惊喜,,柔和和温暖.
- 多变量分析评估了调制/不调制超声波和真实纹理之间的感知相似性.
主要成果:
- 超声波刺激与一些刚性材料 (树脂,砂纸,) 在有区别的触摸尺寸上有所不同.
- 振幅调节的超声波 (10 Hz) 被认为比砂纸更令人愉快.
- 超过一半的参与者将调制超声波识别为刷子或棉花,表明与真实纹理有显著的感知重叠.
结论:
- 中空触觉,特别是振幅调制,可以唤起类似于真实纹理的感知属性,包括在毛的皮肤上柔软的刷子.
- 幅度调制显著提高了空中触觉反的真实性.
- 这项研究为使用超声波技术实现现实的虚拟触摸体验开辟了可能性.

Ultrasonography
7.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Tactile and Chemical Senses
675
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.
