Web of TacTile Things: Towards an Open and Standardized Platform for Tactile Things via the W3C Web of Things

This work introduces our attempt for an open and standardized platform for tactile things, namely Web of Tactile Thing (WoTT). The WoTT extends the W3C Web of Things (WoT) to exchange haptic information from tactile sensing devices to cross-domain services via already proven Web technologies. We propose (i) haptic vocabularies to generate the WoT Thing Description for vision-based tactile sensing devices, as well as (ii) mechanisms to connect, update, and exchange tactile information efficiently. To prove the feasibility of the platform, a proof of concept includes (i) a tactile sensing device to produce tactile information and (ii) a WoT client that consumes proposed vocabularies to create a digital twin of the physical device, have been implemented. The feasibility of the proposed platform has been verified by abilities to reproduce the digital twin and reflect touch events timely and correctly via the WoTT.
