Engineers and computer types should never be allowed to design user interfaces. They love strange and over the top approaches; who else would have thought that hitting the <Ctrl> <Alt> <Del> keys on a keyboard would be the best way to reboot a computer. This is likely the reason that all these intellectuals are stumped by the projection system...
Apple seems to have been the only group to have figured out that an industrial designer, who understands "human needs" were able to move the rest of the world in the right direction; not only the product design but also how the user interface is designed. More companies need to let people like Jony Ive (

When it comes to cameras, the German industrial designer, Luigi Colani greatly influenced the modern Canon cameras and the Italian industrial designer Giorgetto Giugiaro's work with Nikon is legendary.
