We've see a myriad of methods to communicate and even learn Braille, but we'll admit, most of the previous iterations lacked that sense of excitement necessary to motivate most folks to assimilate something new. Akinori Oishi's creation, however, seeks to be different, as the OtoTenji interactive machine allows users to press touch-sensitive pads and then hear back the letter / character in which they've signaled. We've no word on whether or not the machine is programmed to handle a one-on-one Braille spelling challenge, but if you're interested in just how this peculiar teaching tool actually goes about its business, be sure to click on through for a videotaped demonstration.
