面部表情在日常社会交往中起着重要作用。为了增强视障人士的日常生活体验，我们提出了面部表情外观振动触觉系统（feat），该系统使用振动触觉椅作为视障人士的社交界面。一组振动马达被空间地安装在办公椅的背面。将局部线性嵌入（LLE）算法扩展到计算面部表情的流形，并将其用于控制电机的振动以呈现情绪。因此，椅子可以为视障人士提供与他/她交流的人的在线动态情感信息。对系统进行了可用性评估。结果令人鼓舞，并展示了视障人士的可用性。用户研究表明，该方法对情感类型的识别准确率较高。
Facial expressions play an important role in every day social interaction. To enhance the daily life experience for the visually impaired, we present the Facial Expression Appearance vibroTactile System (FEATS), which uses a vibrotactile chair as the social interface for the visually impaired. An array of vibrating motors are mounted spatially on the back of an office chair. The Locally Linear Embedding (LLE) algorithm is extended to compute the manifold of facial expressions, which is used to control vibration of motors to render emotions. Thus, the chair could provide the visually impaired with on-line dynamic emotion information about the person he/she is communicating with. Usability evaluation of the system is carried out. The results are encouraging and demonstrate usability for the visually impaired. The user studies show that perfect recognition accuracy of emotion type is achieved by the FEATS.
