Smart Self-Service Scales

Roland Piquepaille writes "German researchers have developed intelligent self-service scales for supermarkets, able to recognize fruit or vegetables placed on them (photo). The scales automatically recognize the item being weighed and ask the customer to choose between only those icons that are relevant, such as various kinds of tomatoes. The scales are equipped with a camera and an image evaluation algorithm that compares the image of the item on the scale with images stored in its database. Store managers can add items to the database. The scales are now being tested in about 300 supermarkets across Europe."

      Stores that do this, too, just don't understand that the whole reason people do retail these days is because of the people. A supermarket is a social occasion, and, actually talking to a checkout person for 5 seconds is, well, a human experience. I was loyal to my Wawa (a convenience store) for the longest time largely because the person who worked there took 2 seconds to throw in a sausage egg and cheese into the oven for my wife when they had run out of the ones they'd already made. You can't get that kind of flexibility out of a robot.

      I like the self-checkout, it's fast and convenient. Kroger's works great, Walmart's isn't that good (i dislike the store a bit too, tbh).

      But the small discount is probably doable if we take the money saved and convert it. Let's say they convert 2 normal lanes into 6 self-checkouts. That removes 1 employee (still need one to oversee the self-checkouts). Let's say 9 US dollars an hour is saved. You could get a discount of 15 cents US per minute. Ah, but wait, there is 6 self-service lanes which means you get 2.5 cents US per minute discount. Hardly worth it, imo.

    I don't know how widespread these are outside the UK, but ever used one of the self-service checkouts that are appearing? Scan item, bag it, scan next item etc...

    Great idea. Except that the whole point is to save time, and these things were clearly never tested by someone in a hurry because it's trivially easy to scan and bag faster than the checkout can keep up. Well, it would be except the damn thing refuses to scan item 2 until item 1 has been bagged and it takes forever to register that item 1 has been bagged.

    They're only faster if the supermarket is full of technophobic customers and the checkouts have a queue going out the door.

      Great idea, flawed execution - you're not wrong. Whilst I still use them at my local Tescos, I use them because I take a calculated guess that I can deal with the self-service system and its bugs and short queue quicker than queuing up in the long line at the conventional checkout line.

      I'm usually the guy who's standing there muttering "C'mon, c'mon!" under his breath whilst waiting for the damn thing to recognise that I really have scanned my purchase and placed it on the checkout roller. The annoying thing is you could see how it could be really great - better scanners, faster recognition: swipe, bag, insert card and you're done.
      (Thinking about it, having self-checkout that's a bit of a pain to use unless you're slightly geek-savvy might not be a bad thing - keeps the queues down for us)

    Just a few days ago when I was shopping with my family at a "real" store (maybe comparable to WalMart in the US) in Potsdam (near Berlin), I was confronted with this kind of scale. The scale looks similar to the standard self service scales, but it sports a touch screen instead of the panel with selection buttons. The camera is also included in the touch sceen.

    After I had placed a clear bag with nectarines on the scale it displayed a number of selections that it considered the appropriate type of fruit. None of the selections came even close, so I had to select "nectarines" manually on the touch sceen.

    Generally this is a nice idea, but it just does not seem to work, maybe also because we always place the fuits in bags before putting them on the scale.

    Usually stores do have the facility for the check-out person to enter the code and weigh the fruit themselves at the checkout, but as they only do this when tourists come to town (or the OAPs who forget) they don't remember the codes off the top of their heads and have to spend a while looking them up.

    In Australia, it is standard for the "checkout chick" to weigh fruit & veg (or anything else) as part of of the checkout process. The scales are built into the bench/barcode scanner and it takes maybe a second longer than a typical barcode scan.

    (Which resulted in a bit of minor confusion and embarrassment the first time I visited a grocery store in Switzerland after we moved here.)

    Having seen both systems in action, I'm in favour of having it done at the checkout. It doesn't add any meaningful amount of time, is more convenient for the customer and removes the ability for dishonest people to game the system by deliberately using an incorrect label on their goods.

    Every time I go in, a clipboard-wielding junior manager tries to make me use them. I usually just say "No", but next time I've resolved to explain why.

    Completely aside from the fact that the implementation is dreadful, the things are designed to do people out of a job, in a town that sorely needs jobs. Two of these things are typically supervised by one worker, instead of requiring two people to man two manual ones. You only spend on capital if you have an expectation of increased quality or reduced labour costs, and I can't see these things increasing quality.

    People who work grocery retail are at the bottom end of the labour market, so where are they going to go? I don't feel comfortable helping the the likes of Tesco line their pockets like this.

None of them gave a shit about their GCSEs, despite (because of?) the fact that they were going to be leaving school straight after them.

I always wonder what percentage will grow up to look back on their GCSE exams and realise that they should have worked harder.

      Most of my friends on the other hand have worked their arses off at top universities but are finding it impossible to get the jobs they wanted because of the credit crunch and companies tightening their belts. Yet you think we should be hiring unskilled wasters instead of the talented people who have worked their whole lives?

    Depends on the store. In germany they often do it at checkout, also probably at aldi in switzerland. At one particularly annoying store in germany (edeka), you have to type in a 3-digit number at the scale. So you spend a lot of time looking for the place where you got your fruit or vegetable, remembering the number, going back.

    These "smart" scales have been around for more than a year now at some Real,- stores, and if they are supposed to intelligently learn, they are apparently still not doing a very good job. Still, anything beats the number system.
