The system will enable us to determine what benefit; in terms of enhanced understanding and clarity of perception; such 3D displays; combined with enhanced information presentation; can provide to the controller. It is hoped that improvements in this area will permit more efficient and safe management of more aircraft over a wider airspace. Interaction schemes have initially been centred around the use of 3D interactors such as a 3D pointer but we have recently implemented a scheme for voice recognition which allows the user access to a much wider range of commands and actions without recourse to a static keyboard or complex button combinations. The exploitation of carefully selected voice controls frees the user to work within the VR environment using little or no hand-based interaction.
We intend to continue development of this system and expect that it will form an evaluation test bed for a wide range of new VR; 3D and other interaction technologies within this application area in the future.
