Surely the cable is going off to the ear piece.

It really doesn't look like it to me. I suspect it is webcam data being fed to a computer. I think the ring is currently only a camera and vibration motor with the electronics to control them both. I could totally be wrong though, and kind of hope I am!

@Caleb

Looks as though you're right:- from 

http://fluid.media.mit.edu/sites/default/files/paper317.pdf

_________________________________________________________________

Our software runs on Mac and Windows machines, and the source code is available to download1. We focused on runtime efficiency, and typical frame processing time on our machine is within 20ms, which is suitable for realtime processing. Low running time is important to support randomly skimming text as well as for feedback, for the user gets an immediate response once a text region is detected.

 

1 Source code is currently hosted at: http://github.com/

Hopefully if this comes to fruition they'll transfer the software to Android etc.

For an early prototype like this, I wouldn't have expected too much. They've proven the concept though, so maybe now they could work on miniaturizing the components... if there's enough interest. This is the MIT media lab, not a company trying to develop/sell a product.

It's amazing that we take this stuff so much for granted -- I see this and think -- "that's not a bad idea" -- if you'd shown me this 20 years ago I would have been jumping up and down screaming "OMG!!!"

It would have seemed almost rediculously naive to think that this would actually exist, had you seen it 20 years ago. Much like seeing the predictions of the yer 2000 from the early 1900s.

20+ years ago I purchased a small hand-held scanner from the renowned DAK enterprises (are they still going??).  Their catalogue was full of phrases like "Finely crafted" and "State of the art" and you'd think you were getting gold-plated stuff.  Alas, this scanner had an uneven roller and elongated the scan once per roller revolution - very noticeable on text..  I was in Zimbabwe and a friend in the USA had sent it to me so there was no chance of getting a refund or replacement.

The finger scanner is a great idea and I see no reason why it shouldn't work, but I can't help wondering what Drew Allan Kaplan himself would have said about it in his catalogue if he sold them :-)

It reminds me of the Optacon (OPtical to TActile CONverter) from the 1960's.  In scanning the Wikipedia article, it references the Optophone from 1913.  So my reaction is not exactly "OMG".

Oh, very nice! thanks for the links!

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
