Multi-touch surface table with multi-point tactile feedback

Abstract

Currently, most of multi-touch surface tables do not provide any tactile feedback to the users. In this paper, a multi-touch surface table with tactile feedback is proposed. The proposed surface table provides the users with the ability of multi-point tactile feedback with variant patterns and levels of vibrations. A webcam is used to capture all finger-touch images as system inputs using computer vision. Interactive computer graphics is generated and projected on the surface table. In addition, the multi-point tactile feedback is produced by multiple motors attached below the display surface. Hence, the user will receive tactile feedback synchronized with multi-point interactive computer graphics. © 2011 Springer-Verlag.
