In the early 1970s, a Swedish engineer named Håkan Lans invented a tool for facilitating personal computer workflow. The device, which he called the "digitizer" was a point-and-click tool that connected to a machine's regular keyboard outlet. The invention never took off then, Lans didn't even take out a patent, but a few years later, Stephen Jobs and colleagues introduced the world to the computer mouse. Much has happened since, it's taken different forms, shapes and colors, it even became intelligent and now, there's an ergonomie solution, also originating in Sweden - the Trackbar Emotion, an economically correct computer mouse replacement device, which received the "Attendees' Choice" award at the National Ergonomic Conference and Exposition, held in Las Vegas in December, 2007.
