The current generation of mice that work in two dimensions and have to use buttons and keyboard shortcuts to move in 3D space may about to be superceded by a truly three dimensional mouse. The Quattro mouse may look like a normal mouse, but it can be titled, twisted and turned as if in 3D space. The mouse uses the Hall Effect, discovered over 130 years by Edwin Hall, which allows an extremely sensitive measuring and sensing device to be created using electric current and a magnetic field. The mouse currently exists as a prototype - and creators Hall Effect Technologies are looking to work with hardware and software manufacturers to get the mouse integrated into 3D modelling and CAD systems. The company, which as yet does not have a Web site, can be contacted on 0161 877 7488.
