Sense Substitution

Two interesting products from the field of neural interfaces.

Both of them leverage the fact that our sensory organs are just transducers which give inputs to a really flexible and remarkable signal processing system called the brain. This makes it possible to use one sensory organ to achieve a similar result to that of another. Sensory substitution.

In a very indirect way, sign-language or braille could be considered as external sense substitutions. But these two instances that I came across thanks to Engadget and Google, a few months ago, are much more direct. Interestingly, this article from HowStuffWorks seems to suggest that folks have been trying this since the 1900s!

The first is called BrainPort (their corporate site talks about a more clinical use of their product).
Essentially, here vision is being substituted by taste!
Do watch the following video:


And heres the second one.
Check out this browser screenshot to know how I came across this ;-)

I think this (seeingwithsound) is a way cooler solution. The interface is much more natural and amenable to daily use. Well, here, vision is being substituted by stereo sound - almost sonar.

In case you want to try what this feels like, just download their free windows software winvoice, plug in your web cam and put on a stereo headset. Definitely has room for improvement, but I like the ease and simplicity it offers (they even have j2me, winmo and android mobile phone app versions!).

The best part - both of them are non-invasive, non-risky and do not cost a lot. I hope this helps a lot of people who really need it now. Certainly good news.

Aggregation of Senses

I like Nostradamizing the future of telecommunications. So, if you're in the mood for some etherspeak; read on...

One major hypothesis I have is that user interfaces will be neural in nature.

Here's another one: Services in the future will be about aggregation of senses.

Just look around- Blogs are an aggregation of personal journals. Social Networking is about aggregation of weak-relationships. Advertisement is about aggregation of perceived demand. Cloud Computing aggregates processing power. Malls and Shopping Centers aggregate sales. Indices aggregate performance. Cities aggregate people. Banks aggregate liabilities and assets, Cosmopolitanism aggregates outlooks. The list is varied and colorful. (Btw, a list aggregates items ;))

I think we intuitively like to see things bundled together.

So, what does aggregation do?
It:
-Hides complexities
-Introduces redundancy
-Eliminates single points of failures
-Massively empowers
-Still maintains individual identity
-Assumes positive outcomes for decisions made on/by scale ('all' cannot be wrong)

Heres what I mean by aggregation of senses.
In the far future, thanks to neural inter-networks, decisions, opinions and actions could be based on collective sensory experiences.

• It will no longer matter if a friend is visually impaired, because vision would already have been aggregated, he could easily see through the eyes of his willing friends or even his cellphone camera. Maybe, even the cellphone would no longer need a camera!

• When you drive (your futurecar), if you've subscribed to drive aggregation on the road, you'll be able to easily speak on the cell phone while you drive at 300 mph, because when you do, the necessary inputs and processing for avoiding mishaps will come from various people in your proximity and even electronic sensors within the vehicle and on the road

• Virtual people will have 'real' implications. Virtual worlds will exist seamlessly with the real world.

By the time these things come to pass, the human brain would also have evolved sufficiently to handle such large volumes of data. Information density per person in 2009 is definitely magnitudes larger than what it was in 1909 and the only way it is heading is north, unless the human race decides one fine morning to completely shun technology.

This is the kind of stuff, that I think the Googles of the future will be busy provisioning, the people of the future subscribing to and the payment companies of the future banking on.

Snap, snap... back to reality.
