  Designed with an accessible first design approach, the presented paper
describes how exploiting humans proprioception ability in 3D space can result
in a more natural interaction experience when using a 3D graphical user
interface in a virtual environment. The modularity of the designed interface
empowers the user to decide where they want to place interface elements in 3D
space allowing for a highly customizable experience, both in the context of the
player and the virtual space. Drawing inspiration from todays tangible
interfaces used, such as those in aircraft cockpits, a modular interface is
presented taking advantage of our natural understanding of interacting with 3D
objects and exploiting capabilities that otherwise have not been used in 2D
interaction. Additionally, the designed interface supports multimodal input
mechanisms which also demonstrates the opportunity for the design to cross over
to augmented reality applications. A focus group study was completed to better
understand the usability and constraints of the designed 3D GUI.
