While we recently saw just how important listening to your DAP
could eventually become when trying to shuffle through menus and playlists, a team of researchers at Swansea and Glasgow Universities are hoping to throw GPS into the mix while we're at it. Essentially, DAP / PMP owners would be able to program a destination into their handheld, and if headed in the right direction, music would be delivered in a perfect stereo split. Heading off course, however, would shift the volume to one ear or the other, providing auditory cues
of which way to turn in order to get back on track. Moreover, customized POI preferences could be programmed in so that users could be given an "aural nudge" when passing by something that the device knew would pique his / her interest. Hey, we're down with anything that allows us to focus more on our surroundings and less on that pesky display, but this stuff should probably come with some sort of disclaimer before being loosed on the GPS-obeying
UK crowd (we kid, we kid -- sort of).
