MEMS Motion Sensors Go Mainstream

With all the press lately about Sony's
Playstation 3 and Nintendo's
Wii the popular focus for game consoles is primarily on better graphics
and faster processors. While in the past, game platforms seem to have competed
on the basis of software, graphics and speed, the latest generation of consoles
let game controllers finally get in on the action.
These
new game controllers make use of tiny silicon based MEMS chips
that serve as motion detectors. This addition of motion sensitive game control
will represent a significant enhancement for players and more user interface
options for game designers and developers. Nintendo's Wii controller even
ups the ante by adding infra-red sensors that allow the user point to things
on screen.
So what's the big deal? These capabilities were on the leading edge of both
technology and cost just a few years ago, migrating from the auto industry,
they have now found their way into mass distribution via the consumer electronics
pipeline. Thanks to MEMS technology, these capabilities are mass produced on
silicon wafers and sold at consumer price points.
Game controllers are just the beginning. These new MEMS based motion sensing
solutions will soon find their way into everything that would benefit. Of particular
interest to me is how they will improve user interfaces for mobile IT technologies.
One thing that comes to mind immediately for me is the long awaited affordable
and practical gesture
interface.
