The document discusses several projects involving virtual reality and simulation tools for manufacturing and design applications. It describes using virtual reality to simulate factory floor operations like machine layout and part flow. It also discusses developing haptic and graphical interfaces to optimize design and manufacturing systems and guide users to optimal solutions. Several medical applications are mentioned like virtual inspection of dental implants, planning minimally invasive surgery, and analyzing brain tumor spectra.
2. Virtual Factory Project Virtual Reality and Synthetic Manufacturing Laboratory, University at Buffalo Cellular formation of machines within the factory floor Simulation of part flow between machines Provide a walkthrough mode for the operator to navigate the virtual factory environment for inspection and decision making.
4. A HAPTICS AND GRAPHICS BASED DECISION MAKING ENVIRONMENT Optimization Engine  Our mission is to apply Virtual and Synthetic Engineering tools towards achieving an integrated haptics and graphic framework for simulation-based optimization of Manufacturing and Design Systems . Graphical Feedback Haptic Feedback Optimum The graph in the above figure shows three trials for the placement of the blocks. One set of experiments is complete when an optimal solution is reached. The designer makes a decision using the color of the blocks, relative size and visual and haptic cues. Users strongly prefer a combination of both haptic effects and the graph for decision making. Input Variable Proposed module for Haptics based integrated visualization environment 1000 HZ 30 HZ  Clearly the interaction between the computation, visualization and haptic loop decides performance measure and has to be carefully studied.
