Interactive walk-through by a simple bicycle fitness facility on a GPU-accelerated terrain visualization system

Current bicycle fitness facilities mostly do not provide interactive visual feedback. People usually feel boring after using such kind of facilities for a few minutes. To cope with this, we presented a simple system that combines a simple bicycle fitness facility with a terrain visualization system. With the new system, the user may use the bicycle fitness facility as an input device to our terrain visualization system and interactive experience of riding on the custom load terrain in the virtual world.
