There is a lot of focus on the mechanics of UIs, such as you mention from your seminar, and not enough on understanding. In the XO case, understanding is supported by collaborative discovery. We don't feel the need for one-word user manuals on controls. Try it. See what happens. This works much better with children, who are fearless explorers in such a safe domain, than it does with adults who are more rigid or more fearful in their thinking. Or both. A willingness to explore, to build one's own mental maps and models, is essential for dealing with complex software, complex topics, and the complex world we inhabit. The worst UI I know is the one I remember from grade school math. Here are the approved problems, with a space for one answer each. Then *we* will grade *you* on your performance. Children feel like the mouse in Lewis Carroll's poem: Fury said to a mouse That he met in the house, "Let us both go to law. *I* will prosecute *you*. "Come, I'll take no denial. We must have a trial, For really this morning I've nothing to do." Said the mouse to the cur, "Such a trial, dear sir, Without jury or judge Would be wasting our breath." "I'll be judge! I'll be jury!" Said cunning old Fury. "I'll try the whole cause and condemn you to death." Instead of that, they could be teaching the computer how to do arithmetic and what have you. Everybody knows that you learn a subject better by teaching it. > Best regards > Manuel -- Edward Cherlin Earth Treasury: End Poverty at a Profit http://www.EarthTreasury.org/ "The best way to predict the future is to invent it."--Alan Kay _______________________________________________ Olpc-open mailing list [email protected] http://lists.laptop.org/listinfo/olpc-open
