The German Fraunhofer Institut for Medienkommunikation [IMK] develops a gesture based interface based on electric field sensing principle.

The EFS react directly on the physical condition and properties of the human body such as capacitance and conductance. This metaphorically exemplifies the attempt to explore new ways of reading the human body with computer systems, starting with their physical properties. Interaction is based on "body mapping"- no single point of the body is controlling the interface, instead any part can affect the resulting effects. Spatial memory, spatial thinking and feeling are the basis of interaction using EFS. Read more on the project web page.

The navigation in 3D is still an unsolved problem. The keyboard mouse combination every hard-core First person shooter player is using is just a crutch. But it is currently still the most efficient way to navigate in 3D virtual spaces. Maybe EFS can be the solution.
