Date posted: 09/10/2006 First demonstrated at Wired NextFest on Friday, September 29, 2006, the Virtue Canoe is a product of from the Technology Institute of Tokyo.
The virtual canoe consists of several parts. There is the canoe itself, in which you sit. A seven foot high C1 projection screen in front of you, showing the section of river coming next, in considerable detail. A pool of virtual water below the canoe, represented by a mat, which responds to pressure, force, and waves created in the virtual world you are looking at. A haptic-wired paddle which feeds back the appropriate level of effort, and/or pressure sensations and drag, as it would do in an actual river under those conditions. Currently, it runs with a real-time water simulator with a pre-computed database of 3D fluid dynamics. The system simulates a real-time wave model with a database for complex and fast-flow areas around objects that creates realistic wakes and force feedback of water resistance. Virtual Canoe combines a pre-computed database and a real-time simulation ? something rarely done as of yet. The researchers believe both components are required to establish a realistic waveform. The real-time component is just a wave-function simulator, so it simply transmits water pressure and velocity. The pre-computed database provides a force pattern for any point on an object's surface, sort-of like a massively complex lookup table, that bypasses the need to compute in real-time. The pressure from the database affects the velocity of the water in the real-time wave simulation, which keys the query to the database. This enables the system to create a realistic waveform. The goal of the virtual canoe project its to create a real-time fluid model for use in all virtual environments, properly simulating the effects of flowing water, oil, tar, and any liquid. On top of that, it will develop visualisation/haptisation methods for interfacing with the fluid model, and to understand how fluids should move and flow for use in engineering.
