I am not on the Facebook wagon but I found the controversy over Facebook’s Beacon interesting. Users were inadvertently displaying their online purchases to their friends on Facebook. Facebook claims that users could opt-out of showing this information but many users said it was not obvious. Here are some before and after screenshots [from the NYT blog entry]:
I was browsing the nutrition information for Moe’s the other day and was struck by the uniqueness of their interface. It let’s you specify exactly what you order, exactly how you order, at their restaurant. Give it a try (click on “Nutrition” in the menu at bottom.) This is obviously an interface for those who need to know just how many calories are in those jalapeno bits.
As an informal comparison, check out these interfaces from Taco Bell,McDonald’s, and Burger King. They all make assumptions, perhaps correct, about their users. For example, it was pointed out to me that taco bell makes sure it’s easy for you to have more than one of the same item (since that’s how people order… two soft tacos, please).
McDonald’s seems to think that importing the same table they provide in-restaurant is the way to go.
Burger King pretends to be novel, with the “big book of nutrition”, but exploration of any item eventually turns up a table.
It does seem to be the most parental of the sites, offering as many tips on how to eat as telling you what they serve.
These interfaces are so rich with both good and bad human factors, I can’t possibly cover it in one post. Let us know your favorites!
