Nanotechnology is being used to make
tiny objects (100 millionth of a
millimetre or less) that can augment
reality: such as contact lenses with
overlays and a Braille keyboard with
refreshable soft cells that will improve
interaction with computers. Apple is
among those developing technology to
make our mobile use of AR more
interactive. VR has become essential in
industries such as automotive, oil and
gas, to the visualisation of complex
processes. Accountants are using the
virtual world Second Life to recruit
trainees, attract clients and develop
new lines of business, and holding
meetings in online role-playing games
such as World of Warcraft.
