Human computer interaction laboratory was built and equipped with the recent available peripheral devices for virtual reality. New collision detection algorithms for static and dynamic scenes take advantage of bounding volumes hierarchy with k-DOPs. The solution of dynamic collision tasks is based on prediction using hierarchy of extended k-DOPs.
The generic graphics architecture serves as the pattern for a scene graph implementation as well as for an implementation of global rendering techniques.
It allows to harmonize haptic rendering with classical rendering of an image of a scene.
A visualization of molecular force fields enriched with haptic exploration and interaction raises the visualization potencial significantly. Theoretically we solved the method for a stable presentation of the results of computational chemistry simulations. The application for their rendering and haptic exploration was designed and implemented.
In the HCI laboratory, huge and complex system connecting peripheral VR devices with computing resources. We realized many experiments with various forms and combinations of interaction methods.
Experiments with haptic force-feedback showed its potential to be used in assistive technologies for visually impaired subjects.
