Designing Virtual and Augmented Reality User Interfaces Using Parameterized Function Structure Models

A challenge when designing virtual and augmented reality interfaces is the fact that such interfaces can, and will, be used in a variety of contexts that cannot be anticipated or controlled by the designer. Further, since a designer cannot accurately predict how an interface will be used, and the context of use of any interface is ever changing, users will appropriate such an interface by developing their own strategies for achieving their goals. This paper introduces parameterized function structures as a tool from design engineering that may be useful in understanding and analyzing the emergent interaction properties of a virtual or augmented reality user interface at an early stage in the design process.
