The Challenge

We focus on the application of augmented, virtual and mixed reality, simulation and visualization environments to genuine end-user problems, and the new tools, techniques and theories needed for their construction. Our particular strengths in underpinning technologies stem from work on novel systems and algorithms for modelling, simulation and rendering, and expertise in building, validating and integrating innovative display modalities.

The Approach

The strategy for ensuring a reputable and sustainable future for the group is to carry out evidence-based, fundamental computer science research that is grounded in the real world of users’ needs and aspirations.

 

Impact

Our impact is both theoretical and application oriented. An exemplar is the team’s theoretical framework on high-precision and efficient geometric reconstruction of human’s vascular system, part of which has been used in a wide range of applications, including MIPAV.

We have developed discipline-leading applications in radiotherapy training, radiological interventions, and training systems in general. VERT - Virtual Environment for Radiotherapy Training, became the foundation of a successful company, Vertual Ltd. VIC (Virtual Incident Command) and LIMA (Large Incident Multiple Agency) software applications, developed in conjunction with Humberside Fire and Rescue Service (HFR) and North Staffordshire Fire and Rescue Services (NSFRS), deliver training for multi-level emergency incidents.

View all projects
  • Wellcome Trust funded project analysing maxillofacial growth using 3D medical image analysis in collaboration with Dundee Dental Hospital and Dundee University. Accurate and robust 3D volume and surface land-marking has been developed to measure the external changes in soft tissues using CT, MRI and photogrammetry imaging modalities

  • The i-BIT project, where Virtual Reality and video games combine to provide a potential treatment for Amblyopia (Lay Eye) in children. The team in collaboration with Nottingham University and NHS Trust have secured both Wellcome Trust and Innovation for Industrial funding, completing two successful sets of clinical trials.

  • An assessment tool to measure and analyse the driving habits and reaction times of older drivers with chronic heart failure, was developed in collaboration with Hull and East Yorkshire NHS Trust.

  • An orthopaedic surgical training system, to build key procedure specific navigation skills, has been developed in collaboration with Northern Lincolnshire and Goole NHS Foundation Trust.

  • The application of GPU based Monte Carlo and Lattice Boltzmann physics simulations linked to computer graphics for special effects such as smoke and fire.
