Remapping human sensation

There's a good article in today's NYTimes about Dr. Paul Bach-y-Rita's work in remapping human sensation — allowing the blind to "see" via tactile feedback on the tongue for example. Sounds like there have been some breakthroughs recently in terms of miniaturization and wearability (no surprise there), plus some good results in allowing people with damaged vestibular systems to regain normal balance unaided.
