Computational chemistry began with the birth of computers in the mid 1900s, and its growth has been directly coupled to the technological advances made in computer science and high-performance computing. A popular goal within the field, be it Newtonian or quantum based methods, is the accurate modelling of physical forces and energetics through mathematics and algorithm design. Through reliable modelling of the underlying forces, molecular simulations frequently provide atomistic insights into macroscopic experimental observations.
Imagine a person navigating on the trackball of a mouse - it would need full body control. In this article we describe the Virtual Balance, an input device for a responsive virtual environment. This device is driven by weight shift on a small platform and does neither require special training nor wearing uncomfortable equipment. The Virtual Balance aims at intuitive navigation through complex 3D space. It can be used to skate or fly like on a magic carpet through a virtual world. With shifts of body posture the navigator controls speed and direction of his/her movement in the model world, which is calculated from the changing pressure on three weight cells under the platform. Different fields of application are presented, showing scenarios already realized as well as a variety of possibilities for future use.
