The MSVT is an immersive analytics system to analyze the result of computation fluid dynamics simulation. Three different visualization tools can be used to observe the trajectory of particle: streamlines, rakes, and colorplanes.

To navigate through the visualization, two datagloves are used. The movement are similar to classical touch device, i.e. closing a fist and moving your hand pan the representation, while closing two hands then moving them is used to perform rotation and scaling. The particularity of MSVT is to use voice recognition, which allow the user to pick up and drop tool by saying “Pick up” or “Drop” or removing visualization tool by saying “Remove”. Both interaction affecting the closest object from the dataglove. Moreover, snapshot of the current view is possible by saying “remember this view”.
