Headband Gives Wearer "Sixth-Sense" 234

Posted by ScuttleMonkey from the use-the-force dept.
An anonymous reader writes "New Scientist reports on a headband developed at the University of Tokyo that allows the wearer to feel their surroundings at a distance — as if they had cats whiskers. Infrared sensors positioned around the headband vibrate to signal when and where an object is close. There are also a few great videos of people using it to dodge stuff while blindfolded."

    Augmentation of existing senses has been going on for some time now. In particular, there is a very interesting project running through the Office of Naval Research using Navy Seals and a tongue prosthetic designed to impart sonar information to the tongue using electrical stimulii. Technology like this is very cool stuff that at the very least will help with mission specific tasks, but even better allows folks who have one or more senses compromised to continue to function and navigate their worlds.

      This seems to make sense for those who are blind. Instead of using the walking stick/cane (not sure what it's called). Just strap one of these things to their head/chest/belt and let them walk on. It could vibrate to indicate steps, objects, drop offs, etc.

      I don't know why this hasn't been thought of before...perhaps it has been, but not that i've heard of.

        Actually, one of the main features of the walking-stick/cane is that it helps detect features just above ground level, such as curbs and stairs. A band wrapped around the head would help against trees and walls, but not against the curb.

            Why do nerds insist on constantly trying to reinvent the wheel? IR shoes are a rubbish substitute for a cane. They would only indicate the presence of an obstacle, they wouldn't have any information about it, concrete block would seem the same as a piece of cardboard, you would have to make a detour for every bit of litter. And you wouldn't know what was on the other side of an obstacle, a curb could have a nice wide pavement on the other side, or there could be a brick wall, or a ditch, but you wouldn't know until you put your foot over it. Also, a came tells you what the ground is like, if it is a loose surface, or if there is a huge mud puddle in front of you, IR shoes could never tell you that stuff as easily as a cane could.

        Heh, but we have been doing this for years. What is my car but an augmentation to my ability to move?

        It took moments to begin, but nearly 10 years or so to rewire my brain, but its pretty good at both cars and motorcycles now. Whens the last time you really had to think about it? I don't think "Ok 4k RPMs, lets toss it into the next gear". No, I press the gas, the car speeds up and I just do it.... information comes in via my senses (vibration being a real key, more than most) and I do the right thing, the same thing, over and over.

        Even if I spin out, its not like I think "ok, I am sliding, what do I do in a slide, steer into it..." no. the car starts to slide, and I just react, do the right thing, and continue on my way. The adrenalin doesn't even hit anymore. My brain has done it, learned it, and is ready to do it again as needed.

        Its no different from mastering any skill. Think how well your brain is wired to use a mouse, a keyboard. Ever seen someone sit down for the first time and see how unskilled they are with the mouse?

        I am not really surprized, but I do think that realizing this explicitly and looking at how we can use these aspects of our minds is quite a neat area of research. I hope we see a lot more of this sort of thing.

        how about heat vision? sensor to track where the eyes are focused, take a surface temp reading, and use some sort of vibrational or sensational output so you can feel the temperature. No longer would hot glass look like cold glass, you would cast your eyes upon them and know. Could be useful with peoples body heat too. Liars? Sexual arousal? Illness? so many uses!

Then there's the sense of thoughtforms, the ability to know one's own thoughts and feelings, and the sense of self, which is the only thing that lets us do anything useful with our mental models of the world we build out of all the other senses by relating the model of the world to the model of the individual.

    I made almost exactly the same thing at Towson University last semester with a research grant. I have a Daventech SRF04 ultrasonic rangefinder mounted on a baseball cap which is polled by an Acroname Brainstem PIC module. That data is averaged over a short time and sent out to a servo that is strapped to the user's palm. The end result is that the servo presses against the user's palm with a pressure inversely proportional to the distance read by the rangefinder. It really does work very well, it's very responsive and it's not too dificult to at least avoid bumping into things. The only problem is that it's not in stereo; I would eventually like to add more rangefinders and more servos. The other problem is that the user has to move their head around constantly to get distance information; I talked this over with a blind friend of mine and he suggested that the sensor be mounted on the hand or wrist along with the servo, this way it's a little more intuitive and less cumbersome/dorky-looking/tiresome.

    If your hearing in both ears is good and the environment isn't too noisy, you don't need a headband full of electronics and sensors for this.

    With practice you can "image" enough of your environment to get around just from echoes of your own body's sounds or other ambient noises of suitable waveshape. (This is how you get the "closing in" feeling in tight spaces.)

    There are reports of a totally blind kid using this effect to ride a bicycle and avoid obstacles. (He made clicking sounds with his mouth to provide a controlled, sharp (low-distance-error) sound, effectively emulating one mode of a bat's sonar.)

    "Chirps" (single tones rapidly "swept" at a constant change of frequency per unit time) are potentially far better for imaging and ranging than "clicks" (impulses or short sound bursts that approximate them). But it's not clear that the human brain and vocal system has the necessary structures for generating and processing them correctly.

    = = = =

    Of course the headband might be much more effective than training up your own sound-generating and sensory systems - which (unlike a bat's or a cetacean's) aren't optimized for this service.

      This headband using IR radar would probably be much more socially acceptable and less discomfort-inducing than walking around clicking your tongue incessantly.
  • One young test subject, upon wearing the headband, reported that he could "see dead people"...

    The researchers, upon having been thus reminded of an M Night Shyamalan movie, threw themselves out the nearest window to end their grief.

  • I spend a lot of time in caves. Ya wear a helmet. Despite that, you hit your head. *Astoundingly* hard, even with a helmet. All the time. Because you forget there's a huge irregular rock right beside your head, and you turn, and *whang* you hit your head so hard your olfactory nerves distort and you smell/taste copper the way you do when you've been punched.

  • Being a techie/engineer I often end up with screwdrivers, pens etc in my pockets and sometimes one of these gets used as an ear scratcher - yes, I know; bad, risky habit.

    Quite some time ago, I realised that when I approach my ear 'hole' with a pointed object I get a perceptible rumble in that ear (especially the right side) when the tip is around 1-1.5 inches from the opening - there's no physical contact at that time and so I have often wondered whether this is down to subtle changes in air pressure, magne
