[parsehtml]<p><img alt="disney " src="" /></p> <p>Companies and researchers are always trying to find innovative ways to expand the smartphones and tablets we use everyday, whether it&#39;s a new app or some kind of hardware accessory. And now, a&nbsp;team of researchers from Carnegie Mellon University and <a href="">Disney Research</a> are leveraging ultrasonic audio coming from our devices in order to <a href="">develop</a> new kinds of interactive mobile controllers.</p> <p>The research comes in the form of plastic add-ons known as Acoustruments. These accessories send ultrasonic sound from a smartphone&rsquo;s speakers and then re-route it back to its input. An internal app can then analyze the changes in the audio between the output and input to create user commands.&nbsp;</p> <p>The technology could be used to create any number of physical add-ons, not unlike what we see with NFC style toys. As you can see in the example video below, the researchers have a number of prototype applications for the tech including what appear to be interactive kids&rsquo; toys and other flashy phone and tablet controllers/add-ons. We could also see phone cases that can tell when the device is being held, squeezed (pressed) or just resting comfortably on the table.&nbsp;</p> <p>There are no immediate plans for the Acoustruments, but reports suggest the very lower power the technology requires from your smartphone will likely be a draw for some manufacturers.</p> <div class="video-container"><iframe allowfullscreen="" frameborder="0" height="390" src="//;showinfo=0&amp;modestbranding=1&amp;vq=hd720&amp;autohide=1" width="560"></iframe></div><p><a rel='alternate' href='' target='_blank'>Permalink to story.</a></p><p class='permalink'><a rel='alternate' href=''></a></p>[/parsehtml]

    Can it be modified to shoot ultrasonic beams at geese who think they own the road?
