Like Carol, when I first got involved with OLPC, I was surprised to find that so little user testing had been done. I was told by someone that to their knowledge, no formal user testing had been done *at all*. But, as the same person explained, the entire system has been developed by a small number of people under immense time pressure, which naturally makes it difficult to do iterative design. I think everyone is in agreement that it would be great if more user testing could be done on the Sugar interface. But, that doesn't mean everyone agrees on the methods.

Ben, you're right that it will be easier to do testing once the designs have been implemented. But we don't need to fully implement the interface before it has been implemented -- user testing could be done on the existing designs using paper prototyping (http://en.wikipedia.org/wiki/Paper_prototyping) or other lightweight usability methods. This makes it easier to iterate on the designs without wasting a lot of development time. In the end, nothing beats putting a working interface in front of the actual users, but given the constraints of this project, that kind of testing is difficult. For one thing, it's tough for most of the developers to get access to children in developing countries. However, doing some kind of testing is better than nothing. I'd encourage people to do any kind of user testing they can do -- paper prototypes, informal think-alouds with friends and family, etc. Simply putting your design in front of someone who's not familiar with the project will teach you lots. In fact, I just completed a study like this on the Pen Tablet user interface: http://wiki.laptop.org/go/Pen_Tablet_UI/User_Study If there's one conclusion we can make here, it's that we could do a better job in coordinating our usability efforts. In the next few days, I'll try to set up a central place on the wiki that can use to do this. Anyone else who is interested in this can feel free to do so, of simply get in touch with me to let me know you're interested.
