An update from my earlier post: Bytelight, the Boston-based startup that is focusing on visible-light-communications (or “coded light”) for indoor “GPS” functionality has finally launched a public website.

According to their own site:

We believe indoor location is going to be bigger than GPS. The great indoors have been left largely unexplored because the technology for answering the question “Where am I?” hasn’t existed yet. Until now.

Our technology leverages energy efficient LED lighting to re-invent indoor location. We provide a best-in-class solution that’s accurate, fast, and works on any mobile device with a camera. And the best part is that we’re using an infrastructure that needs to be there anyways – the lightbulb.

The obvious uses of such light-based proximity detection systems are retail, large hospitality and museum applications, but Bytelight is also clearly hunting for hackers to figure how to use this stuff in residential applications (I’m guessing they’re doing this to impress VCs).

Their first installation is an exhibit at the Museum of Science in Boston.  Here’s a blog post from Wired with more details on the history of the company.

Humm…a small, innovative lighting technology company located in downtown Boston…where have I seen that before???
