This paper describes an experiment and its results concerning research that has been going on for a number of years in the area of anthropomorphic user interface feedback. The main aims of the research have been to examine the effectiveness and user satisfaction of anthropomorphic feedback in various domains. The results are of use to all interactive(More)
Ever since the development of the first applications in image-guided therapy (IGT), the use of head-mounted displays (HMDs) was considered an important extension of existing IGT technologies. Several approaches to utilizing HMDs and modified medical devices for augmented reality (AR) visualization were implemented. These approaches include video-see through(More)
We present a simple and rapid method for generation of perspective digitally rendered radiographs (DRR) for 2D/3D registration based on splat rendering. Suppression of discretization artefacts by means of computation of Gaussian footprints--which is a considerable computational burden in classical splat rendering--is replaced by stochastic motion of either(More)
We discuss the approximation of the meanfield terms appearing in computations of the multi-configuration time-dependent Hartree–Fock method for the solution of the time-dependent multi-particle (electronic) Schrödinger equation by hierarchical matrices. We give theoretical error bounds for the cross approximation defined by low rank approximations of(More)
