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.
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.
