This TED by David Eagleman has got me to thinking.

Eagleman is also know for research into Synesthesia and has a bestseller and PBS Series about the Secret Lives of the Brain.

He talks about utilizing under-used human sensory receptors (Such as skin tactile neurons on large patches of say your back) to restore or even add to the Human Sensory Package to perceive the world around us: Umwelt.

This is not a new idea, as he explains in the video researchers used solenoid pins in a matrix interfaced with a camera to restore crude sight to the blind, with a tactile device resting in the small of the back, back in 1969.

Where the idea really gets interesting is how any sort of matrix of sensors providing data can be used to educate to brain as to the proper interpretation. At the 11:00 mark we see him discuss the invention of his Grad Student that uses only 24 cell-phone vibrators scattered around the back to provide the deaf with meaningful auditory information.

It works the same way you bar-graph visualization for you MP3 player works. The Auditory Spectrum is sliced into 24 chunks of frequency and the average signal strength for that chunk is fed to one of the vibrators where the intensity of vibration is proportional to signal strength.

In very short order, a guy born deaf was able to recognize spoken words by the pattern induced on his back via these 24 vibrator motors.

Eagleman and Norvich used Bluetooth for visualization effects (As I can't discern another reason) and say they expect the market-end product would cost about $2000 US.





Eagleman goes on to speculate about other uses and notes how other animals use different sensors: Pit Viper Snakes --> Detect IR, Pigeons -->Detect the Earth's Magnetic Field, Bats--> Map using Ultrasound.

Eagleman even ponders an Internet Awareness.

Where can we go with this?

SENSOR MATRIX IDEAS

One though I had was to provide visualization similar to the pioneer work by using a matrix of small disk Piezo buzzers sewn into a Lycra Tank-Top.

These disk are 10mm across (.39") and I was thinking of a matrix of 324 of these (18x18) in a patch on the upper back that was 9"x9" in area. These things cost about a buck each but they vibrate at about 7kHz with a rather limited range of amplitude.

Whereas these 10mm Linear Vibrator 'motors', for cell phone applications, vibrate in a range more in-tune with human detection (175Hz) and are basically little magnetic speakers without the paper cone in front. BUT they cost like $4 each.



Maybe not at all unexpected, my first thoughts turn towards DARPA, but a rational place to start none the less. As Senses are tools for survival and survival comes at a premium cost on the battlefield. Indeed, I do know that the Military already uses a few vibrators against the skin for rudimentary communication in harm's way.

I know there are advances in materials that morph shape when current is applied, but I can't think of the technologies atm.

I love picking up the Lingo while Spelunking.

Haptic Feedback Actuators is the buzzword for these little buttons that push you back, and the field is growing.

These look promising:

Tactile Feedback Display with Spatial and Temporal Resolutions : Scientific Reports : Nature Publishing Group



It's an elastic polymer that expands when you apply current, and by constraining the edge, it bulges upward into the skin.

1500 um is equal to 1.5 mm. So we're talking about form-factors possibly as small as 3 mm in diameter, or about the diameter of a headphones jack.

I also like the fact that it isn't dedicated to just vibrating oscillations like Piezo Buzzers and Linear Cell-phone vibe 'motors', or even old school vibe motors that are truly motors with an off-center load on the axle.

Another problem with these examples is that they propagate oscillating currents and/or magnetic fields. This could be an issue for any DARPA applications.

Any ideas about other types of Haptic feedback Actuators?

What about Matrix ideas?

So some ideas I've started out with:

* An Eye in the back of your head.

Using a regular B&W camera on an IC chip (which also functions as a high-range IR camera) and having the signaled pixelated to match our 18x18 skin transmitter grid:




* If the Camera was on say a headband we could twist it around and use it as a IR camera in the dark. (I'd suggest using a switch to invert the image to mirror when using from behind)

For DARPA Applications, you'd probably want applications with passive detection. That is to say not produce any signal ourselves for a savvy enemy to detect.

For example don't, as in-the-dark security B&W cams do, use IR LEDs to illuminate the surroundings for your IR camera.

But maybe in a less Life & Death situation, we might say PING the world ahead in ultrasound and use a battery of U-S mics on say the helmet to, like bats, learn to map our surroundings in the dark.

Past efforts such as this with deaf people have sent these signals to the ears via headphones for the user to de-code, but they balked at the loss of all the vital auditory information they we already making exceptional use of.

Thus using something like a patch of skin on your back makes a lot more sense. And as for aiding the deaf, this sort of thing is already being done.

* Another idea I had was to incorporate in the aforementioned head-band a ring of vibrators to detect magnetic direction and/or direction to a known location via GPS tracking.

* This brings to mind another DARPA/Police application: Presence and Direction of telecommunication EM radiation. This is especially true of the foot-solder on a modern battlefield with all the electronic situational awareness gear that is out there today, but a cell phone would also betray its owner's location too.

What are some other Energies in our daily environments we could exploit the personal detection of (Perceptions that would enhance our Umwelt)?

I usually suffer from not reading micro Expressions/ques that someone I talk to gives. I find it ok while watching TV. Normally this is due to the reason that I find it awkward to look and trying to read real people's face continuously while they are looking directly at me.
With this technology it is very easy to read and analyze micro expressions of people. #INTJ Application

Much of that stuff looks uber dorky.

A belt or band for the ankle could be relatively concealed and be realisticaly turned into a consumer product. Limited sensitivity and accuracy is still more useful than not wearing it due to societal repercussions.

A four vibrator band detecting magnetic field and special beacons could be useful for the blind.

For lots of stuff you are better off with a hand held device as you are only going to need the sensors situationally. We all carry a pocket computer nowadays and it is a better investment of sensors. It performs calls too.

To clarify: while I dislike the cyborg approach due to impracticability, I am all for externally imperceptible genetic modifications and implants.

Adding a fourth type of cone in our retinas should probably be the first step as it already happens on a few women not to mention animals. We can copy recipes from other species and grow small sensory organs with their features (magnetic lines, light polarization, better echolocation).

Much more practical for normal people.

That's an awesome Idea!

These are good ideas too. I'm not sure a genetically enhanced humans would get past ethical review at this time.

LOL,

Well, I've Simul-posted this thread on several fourms, and one of the discussion lead me to suggest a tapered Dildo or butt pug with arrays of haptic actuators firing in waves that create the sensation of thrusting. :p

How about it just tickles your balls or sends electric current to her nipples via a brain computer interface?

Microsoft Creates Glasses That Can Tell the Emotions of the People You Look At - Softpedia

HoloLens is definitely an out of this world device, but it could take a while until it hits the market, so in the meantime, you might want to have a look at a new pair of glasses developed by Microsoft and which could guess the motions of the people you look at.
