MIT Researchers Create a Cheap "6th Sense" Device

Posted by timothy on from the it-will-tickle-your-fancy-if-you-tell-it-to dept.

thefickler writes "MIT researchers have combined a mobile projector with a webcam and mobile phone to create a device that draws information from the environment. For example, the gadget recognizes products on store shelves and can provide product and price comparison information. The sixth-sense device was cobbled together from common parts costing just $300. While the gadget is not being primed for mass release, it represents a forward-thinking way of blending technology with our environment."

      Yeah, it's ridiculous to call this a "sixth sense". Reading information from a hand-held device is not an additional sense.

      Now, if we were still living 100+ years ago, when people were far more limited in what information they had access to at any given time, *maybe* you could get away with saying this is another sense. But considering that cognitive science researchers -- many probably at MIT -- have had significant success in giving people genuine additional senses (i.e. allow them to observe the world in some way without directly being told the information or thinking aboug it), it's extremely misleading.

      For example, one time on slashdot there was a story about how scientists fed a compass-like transducer into some guy's nervous system, which allowed him to just "know" about changes in the earth's magnetic field or nearby magnets. And in Jeff Hawkins's On Intelligence, he talks about an experiment where they mapped a low-res black/white camera to an array of rods on someone's tongue that push down for black and let up for white, which allow the subject to see without his own eyes.

      Those are new senses. This device isn't.

      My brother and I built one of those. Scroll down to the comments, there are pictures and a description of the circuit. It's not as sophisticated as the MIT one, but it definitely works.

      That, or an implanted magnet to sense EM fields, constitute a "6th sense" imo. Not this.

      Soldering isn't hard. Learn what a cold solder joint is and how not to make them (short version: heat the joint, then let the solder melt on, don't "paint" it on). Use leaded solder (far easier to work with than the lead-free stuff). More doesn't help; it just gets in the way. Don't overdo it. Tin your tip properly when you first get it, and keep it clean with a wet sponge. Oh, and practice a bit on pieces of wire instead of pricey components :)

      The only schematics that were created on that project were napkin sketches and annotations on the datasheet printouts. I'll draw something up, but not before this weekend. I'll post another reply when I do.

    At the heart of the device is a smartphone that uses an Internet connection to retrieve information.

    Further analysis shows that the heart is actually a team of codemonkeys madly devoting all waking hours to understand the hundreds of different data formats needed to supply even the most basic integration.

    Seriously tho, the main cost to developing this would be getting integrated with all the different potential data providers. Recognizing a physical bar code is easy. Looking up the current price at nearby retailers? More difficult.

      I've got a T-Mobile G1 and there are actually a couple of different programs that do this. The one I'm using (and it seems to me the majority of people are using) is ShopSavvy.

      It seems to do a pretty good job of identifying products by barcodes as long as they aren't storebrand items. Its ability to locate the same item at other local stores isn't that great but my guess is that with time they, or someone like them, will build a large enough database and the necessary connections with retailers to make that work. Until then it is mostly useful for looking up reviews for books/DVDs/music and seeing how much I would save going to Amazon, letting me know if I'll save enough to make it worth my while to wait.

    I already have a sixth external sense... it's the sense of acceleration in my inner ear, colloquially known as the sense of balance. That one's just as important as the other senses.

    Of course, there are other more minor senses that are subsets of the sense of touch, like heat and cold, which are actually different mechanisms, but those are arguable as truly separate senses. There's also the sense of body position, whose name escapes me, but that's not an external sense.

      I read an article in the past year about a different "sixth sense" experiment. They made a belt of cellphone-type vibrators, then controlled them such that the northmost vibrator was activated. In essence a built-in compass. Subjects quit noticing the vibration after a few days. Within a few weeks, they had "perfect direction," and it wasn't just the ability to point north, or any other particular direction. Their sense of distance, position, etc, were all much better. The big point of the experiment was to see if an adult brain could internalize and integrate the new information source.

      It could.

      I want one.

      Though it occasionally abandons me, I generally have a very good sense of direction. Let me study a map, get oriented, and I can usually get you there. I can usually give bearing and distance to an arbitrary destination in the general area. But I'd like my sense of direction to be PERFECT. (or darned close to it)

      Incidentally, the effects persisted for several weeks after the device was removed.

      There's also talk about a magnetic grain embedded in the heads of some animals. They've studied the grain, and found that it's the largest size that can naturally be a single magnetic domain. Smaller, and it gives less "signal". Larger, and it splits into multiple domains, and again gives less signal. Sounds like a natural magnetic compass to me. Maybe there's a little bit of residual prewiring in the human brain for such a directional sense, which is why the vibrator belt experiment worked so well.

      I think it's mostly that humans already have a built-in mechanism for dead-reckoning, which is enhanced when we get something to give us additional external cues. Humans generally keep track of which way is north, but it can get out of whack over time.

      I can actually fool my dead-reckoning sense by lying in my bed with my eyes closed and rolling my body over my head, somersault-style. If I don't open my eyes, it feels like I've flipped the bed around in my room. If I open my eyes, the effect immediately vanishes and my direction is restored.
