Google Image Labeler
How does it work?
You'll be randomly paired with a partner who's online and using the feature. Over a two-minute period, you and your partner will be shown the same set of images and asked to provide as many labels as possible to describe each image you see. When your label matches your partner's label, you'll earn points depending on how specific your label is. You'll be shown more images until time runs out. After time expires, you can explore the images you've seen and the websites where those images were found. And we'll show you the points you've earned throughout the session.
