Basically, it is a belt with a bunch of vibrating pads going all around and an electronic compass. Whichever pad is pointing north, vibrates. The end result is that "the tactile perception of the vibrators [disappears] whilst conscious information processing is displaced by a new 'sense of direction'."

I have wanted one for a long time. At first I hoped that modular components would be easy to find and put together. Apparently not so. I then toyed with the idea of making it out of old nokia vibrating batteries and an electronic compass component, but I quickly realized this is way out of my area of expertise. So then I thought, no problem, I'll hire someone with the right skillset. Except, I don't know what the skillset is, or where to start looking.

I figured there would be someone in the HN community who'd be able to point me in the right direction.
