Sixth Senses

I love our posthuman future. I want a heads-up display that tells me what I’m looking at, a radar sense of objects around me, and an internet hookup in my brain. In the meantime, I’m interested in smaller mechanical ways to give additional senses.

The classic example of this, for me, is a magnet in your finger which gives you a sense of metal and electricity. I don’t remember hearing anything about it in the years since the WIRED article, though, and the most recent information I could find was in BMEZine about how they needed better sheaths for the magnets before it would really be safe. Does anyone else know how our posthuman future is progressing?
