InTml: a description language for VR applications

We present the Interaction Technique Markup Language (InTml), a profile on top of the core X3D that describes 3D interaction techniques (InTs) and hardware platforms. InTml makes 3D InTs easier to understand, compare, and integrate in complete virtual reality (VR) applications. InTml can be used as a front end for any VR toolkit, so InTml documents that plug together 3D InTs, VR objects, and devices can be fully described and executed.
