Smart Sofa Recognizes Occupants by Weight 353

Posted by michael from the chubby-hubby dept.
I am Kobayashi writes "According to CNN.com scientists at Trinity College in Dublin have created my dream couch. And yes, I admit to being a couch potato... Apparently the couch can be programmed with a personal greeting (it recognizes you by weight), and the scientists hope that it will one day be able to automatically tune to your favorite television programs, order you take out food, and control other household appliances."

    It won't be able to recognize you by weight if it continues to do absolutely everything for you, like ordering food and changing the channel on the TV without requiring you to get up...

    I wonder if they built an AI into it to intelligently determine who the occupant is by weight gain over time...

      Most people can already do this. They use this amazing invention called a remote control.
    • The current version must have a low-end processor which can only compensate for slow changes in your weight; see quote from researcher:
      "We're hoping that people's weight won't vary so quickly," [researcher Haahr] said. "But it is something we'll have to deal with."
      I'm sure they'll upgrade it in the next version if the chair becomes sufficiently popular. (Kinda like Moore's Law, but for BMI.)
      • "We're hoping that people's weight won't vary so quickly."

        It's going to go up pretty damn quick if the guy doesn't have to leave the couch for anything but the bathroom.

        I can veg out with the best of them, but this? How fricking lazy do you have to be? This thing will tune to your favorite shows automatically. Wow. You don't even have to channel surf for yourself anymore. This is pretty sad.

    • What would the formula for that be though...?

      x = fast food, y = fat content, z = time unites, p = metabolizm.

      x * y - p * 3.14^z = weight gain

      now, when this couch starts getting serious use it would look something like...

      32 / .65 - .40 * 3.14^1u = much weight

      Now... The metabolizm would possibly go up as well as the fat content go down if u could also order pr0n through the same means... that would be a new varialbe p0...

        Well, as unglamourous as a "butt print" is, it would be interesting to see if one can be identified by how one's pressure applies. Different parts push harder due to shape and posture, so if you happen to sit more on your left hip than on your right it should show...

          If people can be identified to some degree by weight alone, I'm sure that having a pressure-sensitive map of someone's weight distribution (butt print) could only be more accurate. Also, you can learn something identifiable by how specific people slouch or lie down, how much they lean back, and other behavioral traits like antsiness. Though detecting these traits would be far more complicated than putting a scale under each pillow.

          Maybe the pillows wouldn't detect weight itself, but the shape of the imprentation using lots of small censors that detect motion. That motion could be integrated (calculus) to calculate their current position. The individual data points could be used together to figure out someone's current position, how their weight is distributed, and how much they move around over time. However, are there affordable censors that can do that? Alternatively, are there censors that can somehow know their absolute location rather than using calculus?
      • well, i think that there is a certain frame within the weight has to lie so that this couch can recognize you. otherwise it would be funny that, each time you change you clothes (say from t-shirts & shorts to a full sized smoking) the couch gets confused and asks for the new username.
      • If I were a scientist, I'd try to identify people based on their butt prints!

        No two skid marks are the same, I suppose.
        • I was tempted to mention that butt-print detecting would be fooled by people shitting their pants, but decided it was too risque.

          In that case, maybe identifying by weight would be more accurate: no weight change! Maybe that's why they're targeting hospitals for the technology?

      A bit off-topic, but has anyone noticed that stores always call couches "sofas" and never "couches?" Examples: Ikea [ikea-usa.com], Pottery Barn [potterybarn.com], Restoration Hardware [restorationhardware.com], Crate & Barrel [crateandbarrel.com] and even Walmart [walmart.com]! When recently looking to buy a new couch, I couldn't find a major site that sold "couches."

      I think company's sell "sofas" because "couches" are perceived as things slothy people buy. Lazy people "lounge on the couch" on the weekends. The American culture always uses the word "couch" to describe unmotivated people's television watching habits.

      But in the eyes of marketers, consumers must see sofas as possessions of elegant, worldly people who are out and about. Motivated, outgoing people buy "sofas" to decorate their posh interiors! "No couches for me, sir, I want a sofa!"
      • Here in Canada, the proper name for a couch, is a chesterfield. although, I still call it a couch. I don't know many people who use the word sofa. But now that I think about it, the word sofa is used a lot in sales. check out this site [harvard.edu] for a list of other interesting canadian words.

Sofa's traditionally are for more than one occupant, so how would it deal with more than one person on it? Furthermore, ignoring the fact that it would be near impossible to get an accurate identity based only on the weight on a sofa, how is it really useful? My sofa knows I'm on it, what does it do for me? It can't really adjust any preferences for devices around me in a manner that is useful, I use my sofa for tons of diffrent uses, having guests over, reading, watching tv, surfing on my laptop, and all of those are would fail to benfit from my sofa knowing that I personally am on it.
