To enhance the daily life experience for visually challengedpersons, the Facial Expression Appearance for Tactile systemis proposed. The manifold of facial expressions is used fortactile perception. Locally Linear Embedding (LLE) codingalgorithm is implemented for tactile display. LLE algorithmis extended to handle the real time video coding. The vibrotactilechair as a social interface for the blind is used to displaythe facial expression. The chair provides the visuallyimpaired with on-line emotion information about the personhe/she is approaching. The preliminary results are encouragingand show that it greatly enhances communication abilityof the visually impaired person.
