Mouse Uses RFID Instead of Batteries

Posted by Zonk on from the bluetooth-concept-replacement dept.

ValourX writes "NewsForge (part of OSTG, like Slashdot) has a review of a mouse that is powered by RFID (and yes, it works with Linux). It's cordless and uses no batteries -- you just have to keep the mouse within 2 inches of the mousepad for it to work. What else could be powered by RFID?"

    The statement that the mouse is powered by RFID is a bit of a misnomer. It may be RF that transmits the mouse movement, but it is actually Inductive Coupling. The mouse pad has a coil that transfers power to a coil in the mouse using magnetic flux. This transfer of power is limited to short distances. Passive RFID uses radio frequency to transmit the power to the tag and relay the information back to the "server". I think that using inductive coupling for Mouse power is a great idea! Anything to reduce consumption of batteries that wind up in a landfill.

    The mouse pad cannot be operated on any metal surface. Since the warnings about this are printed on the box, in the manual, and on the mouse pad itself, I figured it was in my best interest to avoid finding out why metal and power-over-RFID don't mesh.

    Well there's a sentence that sure didn't end the way I wanted it to... Where's his sense of adventure?

    This is actually a step backwards. Optical mouses freed us from having to use a mousepad. Now we not only have to use a mousepad again, we have to have it plugged in.

    No thanks, I'll stick with an truly wireless mouse.
