We propose TouchCast, which is an on-line platform for the creating and sharing of tactile content based on Tactile Copy & Paste. User-Generated Tactile Content refers to tactile content that is created, shared and appreciated by general Internet users. TouchCast enables users to create tactile content by applying tactile textures to existing online content (e.g., illustrations) and to share the created content over the network. Applied textures are scanned from real objects as audio signals, and we call this technique Tactile Copy & Paste. In this study, we implement the system as a Web browser add-on to create User Generated Tactile Content. Copyright is held by the owner/author(s).
