Resumen

The technological evolution has resulted in a series of benefits to the Virtual Reality area. Now it is possible to represent knowledge in an interactive way where visual, haptic and audible aspects are combined, allowing for the improvement of our perception, imagination and manipulation.

Virtual Reality scientists are always improving the interaction with the users using friendly environments and sophisticated tools. Nevertheless, the construction of a virtual environment involves many tasks, such as multi-screen displaying, computer-simulated worlds, stereoscopic...
