Demonstration of Transcalibur - A VR Controller that Presents Various Shapes of Handheld Objects.

We demonstrate Transcalibur, which is a hand-held VR controller that can render a 2D shape by changing its mass properties on a 2D planar area. We built a computational perception model using a data-driven approach from the collected data pairs of mass properties and perceived shapes. This enables Transcalibur to easily and effectively provide convincing shape perception based on complex illusory effects. Our user study showed that the system succeeded in providing the perception of various desired shapes in a virtual environment. In the demonstration, users can explore VR application that can feel the sensation of wielding sword, shield and crossbow and with these fight with a dragon.
