Abstract. In the last years we have witnessed an increasing adoption of haptic devices (allowing the user to feel forces or vibrations) in several fields of applications, from gaming, to mobile, automotive, etc. Some efforts have been done to enhance also Web applications interfaces with haptics, either to improve accessibility or, more in general, to improve usability. Despite the spreading of haptic applications, their development is still a time consuming task that requires significant programming skills. In particular, in the Web context no plug-ins or style extensions are currently available and applications must be developed from scratch. In this paper we describe a framework to easily include haptic interaction in Web applications, focusing both on haptic interaction modeling and on its implementation.
