The one thing that every technologist shares is the desire to solve a problem, and there are several as-yet unsolved issues that relate to disability. It’s not all bad news, however, since in the last few months we’ve seen inventions that help the blind get around, paraplegics play soccer and stroke victims to communicate. Now, researchers at Colorado State University has developed a way that could help the large proportion of people who aren’t able to have a cochlear implant regain a form of hearing.
Rather than attempting to fix the issue, the team has gone the route of sensory substitution, which is to swap out one sense for another. The most common example of this is when blind people feel braille rather than reading text, since the solution here isn’t to cure their blindness, but to find a way around it. Similarly, instead of hearing audible signals, the new device would be an electrode-filled retainer that presses against the roof of your mouth. The retainer would be connected to a Bluetooth microphone, and so when someone spoke, these sounds would be translated into a series of vibrations, which you could then read by pressing your tongue to the roof of your month. All a person would then have to do is learn to decode these vibrations, which is apparently easier to do than some people would believe.
