Abstract

In recent years many advances have enabled users to naturally navigate large-scale graphical worlds. The entertainment industry is increasingly providing visual and body-based cues to users to increase the natural feel of their navigational experience. So far, however, none of the existing solutions fully support the most natural locomotion through virtual worlds. Techniques and technologies which have the advantage of insights into human perceptual sensitivity thus have to be considered. In this context, by far the most natural way to move through the real world is via a full body experience where we receive sensory stimulation to all of our senses, i.e. when walking, running, biking or driving. With some exciting technological advances, people are now beginning to get this same full body sensory experience when navigating computer-generated, three-dimensional environments. Enabling an active and dynamic ability to navigate large-scale virtual scenes is of great interest for many 3D applications demanding locomotion, such as video games, edutainment, simulation, rehabilitation, military, tourism or architecture. Today it is still mostly impossible to freely move through computer generated environments in exactly the same way as the real world. Unnatural and artificial approaches are instead applied, providing only the visual sensation of self-motion. Computer graphics environments were initially restricted to visual displays combined with interaction devices - for example the joystick or mouse - providing often unnatural inputs to generate self-motion. Today, more and more interaction devices like Nintendo Wii, Microsoft Kinect or Sony EyeToy enable intuitive and natural interaction. In this context many research groups are investigating natural, multimodal methods of generating self-motion in virtual worlds based on such consumer hardware.
