A reusable library of 3D interaction techniques

We present a library of reusable, abstract, low granularity components for the development of novel interaction techniques. Based on the InTml language and through an iterative process, we have designed 7 selection and 5 travel techniques from [5] as dataflows of reusable components. The result is a compact set of 30 components that represent interactive content and useful behavior for interaction. We added a library of 20 components for device handling, in order to create complete, portable applications. By design, we achieved a 68% of component reusability, measured as the number of components used in more than one technique, over the total number of used components. As a reusability test, we used this library to describe some interaction techniques in [1], a task that required only 2% of new components.
