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."
Except that the linked picture shows strawberries on the scales, but the screen shows a choice of all kinds of other fruit and veg, not different kinds of strawberry.
Which is better for me as a customer, having someone in checkout that just grabs my tomatoes and enters the price, bags them, or, a stupid robot that makes me do everything. This technology doesn't benefit me at all, it benefits the store. I refuse to use it.
This is my sig.
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.
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.

We have stopped making things, and now increased automation is rendering the service industry pointless. To be honest, like most of the public, I would rather deal with a machine than another human being, if only because that other human being is inevitably some slack-jawed sack of cynicism and self-loathing who hates their job and thus a large percentage of their existence.
The economy of western Europe, therefore, is developing into one based entirely on producing reality TV shows and suing people for sharing them on the Internet. Hooray.

My girlfriend unwittingly leaned across one of these scales to reach a bag of apples, whereupon the screen started showing pictures of different kinds of melons. Fairly accurate, I'd say.

If it could figure out the type op the tomatoes, it should also be able to recognize the things as tomatoes...

... You never removed the bar code from your inflatable life partner? :\
Fact: Everything I say is fiction.
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.
My usual lunchtime shop has trouble reading BARCODES on half the stuff I buy. Swipe, nothing, swipe, nothing, swipe, nothing... Type in tiny number, beep. Yeah, that's time saving. And now I'm being told computers can tell the difference between tangerines and satsumas? Heck, I can't even do that!
I call shenanigans. Either:
* each vegetable has a secret RFID chip in it
or
* the picture is sent to some outsourced call centre where someone sits at a screen watching vegetables all day and clicking on what they are.
But given the level of knowledge of the average checkout person, this might be more useful at the tills - having to explain to the staff what 'fennel' or 'parsnip' (I kid you not - it actually happens) is can get kind of frustrating after a while.
I can see this technology helping the checkout staff - of course, staff training might help as well (looking at you, Tesco...)
One swallow does not a fellatrix make
I refuse to use self-service checkouts. They have installed two of them in the local Tesco (occupies the position that Wal-Mart does in the UK market).
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. I'm starting to feel close to the line where I stop shopping there (if only they hadn't managed to crowd out all the local greengrocers and fishmongers, which I suppose is partially my fault).
Around here, the cashiers don't have to know what it is. Just throw it on the scale and type in the PLU code that's on the sticker.
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.

My grocery store has self service scales and I really love them. They are meant to be used with the portable self checkout scanners. The scanners allow me to scan and bag my groceries as I shop. When I leave, I pay at a small kiosk by the door. I don't have to wait in line even if I shop when the store is very busy. I wish this sort of system was more common.
Fresh Cilantro or Curly Parsley look somewhat similar, and are often thrown in the same bin in the produce department.
You'll sure as hell notice the difference when cooking though!

The problem with regular self check registers is that even though they are more compact, the store still never installs enough of them. If I have to wait in line to use a self service register, it doesn't really save me time. On the other hand, my grocery store has a rack of 100 portable self checkout scanners at the entrance. These allow me to scan and bag my groceries as I shop. This is much more efficient than a self service register or even an actual cashier because I don't have to unload my cart at the register. I've never had to wait to get one and I've never had to wait more than a minute to pay when I'm done.
I can't stand these systems. I said TomAto. It said ToMato. Then I went and tried to get some PotAtos. It said poTato.
Then I just called the whole transaction off.
That depends on how granular it gets. It sounds like it could only narrow it down to "apple" or "tomato"; the weird stuff that drove me batty as a cashier would probably just come up as "weedy thing"...
