Advanced Computer Graphics and Digital Human Lab
Our laboratory research deals with human-oriented modeling and development of visualization systems using VR tools, sensory devices, and experimental data bases. As a basis for the visualization systems, we develop real-time algorithms and methods for gridding, volume rendering, 3D segmentation, mesh reconstruction, and morphing, which are specifics for human-oriented modeling. We conduct body shape modeling using Digital Human manikin models and 3D full-body scan data. Modeling of body shapes can be done for the scenarios of weight gain/loss, muscularity gain, and effects of ageing, which are important for healthcare and beauty services. Combining with motion capture (MoCap) data, 3D scans are used to estimate dynamic parameters, necessary to realistically model human movements. Digital Hand models are used for ergonomics factors estimation, as such as grasp quality and stability. We pay attention to visualization systems with haptic devices for VR surgery and VR nursing. Digital Human modeling is driven by real-time sensory and feedback devices (trackers, accelerometers, haptics), and utilizes experimentally collected data bases (3D scans, CT/MRI data). We also conduct experimental processing of data collected from haptic devices to model and predict human hand movement in constraint dynamic environments and to study human balancing and reaction skills.
