And its games have become popular among the casual gamers market, a market that companies like Microsoft and Sony are trying to reach with new motion-sensing devices like Kinect and PlayStation Move.

As for availability, well, it's pretty clear the hardware will have to come before the software -- a NUIA spokesperson told us she doesn't expect its kit will be commercially available until sensing devices like Tobii become integrated into Windows 8 PCs.

Even so, the equipment-makers argue that, though doable, all this sensing palaver makes white-space devices needlessly complicated and expensive.

The prototype white-space devices used in trials had little trouble sensing occupied TV channels, typically picking them up at signal strengths less than a thousandth of that needed to display an image on a TV screen.

Marvin Sackner, the doctor and inventor behind the LifeShirt, has adapted most of the sensing technology from bedside equipment in hospitals, finding ways to make such devices comfortably portable.

Most of the current wearable devices confine themselves to health and fitness uses and contain basic technology, such as a motion-sensing pedometer that may offer less than precise readings.
