Accessible Tangible User Interfaces in eXtended Reality Experiences for Cultural Heritage

This paper describes three Tangible User Interface (TUI) systems for smartphone-based eXtended Reality (XR) experiences: the Tangible VR Book, the Spectare device, and the Virtual Guia Fortress Playset. These examples, and the interactions they implement, demonstrate how accessible materials and technologies can be used in favor of Cultural Heritage (CH). They show that cheap, easy to find, easy to program materials can be used to create interesting and flexible TUI solutions. We argue that this approach can foster creativity around, and raise interest in CH.
