Many children can not communicate verbally whether due to nonverbal autism
or some other factor. There is a OLPC deployment in Uraguay where a
student uses his stuffed animal as an input device for using an XO and
Etoys. We would like to build on this to make it easier and cheaper for
these children and their parents to communicate and use computers.
In the first project a student would design and document how to hack a
stuffed animal to be used as an input device similar to a joystick or arrow
and a few other keys to allow a nonverbal child to use their favorite
stuffed animal as an input device.
Skills required: Maker skills. To Hack a stuffed animal. Etoys (If student
knows Scratch, they can learn the skills needed in Etoys for this project)
In the second project a student would design a set of picture boards that
could be navigated using a joystick or arrow keys and arrow and few other
keys. The project would also allow a parent or teacher to simply add and
re-arrange pictures using a webcam, imported pictures or simple drawings
that can be made using Etoys. Etoys runs on Linux, Windows and Mac OS
and is one of the core applications in the OLPC XO.
Skills required: Etoys (If student knows Scratch, they can learn the skills
needed in Etoys for this project)

To some of us, writing computer programs is a fascinating game. A program
is a building of thought. It is costless to build, weightless, growing
easily under our typing hands. If we get carried away, its size and
complexity will grow out of control, confusing even the one who created it.
This is the main problem of programming. It is why so much of today's
software tends to crash, fail, screw up.
When a program works, it is beautiful. The art of programming is the skill
of controlling complexity. The great program is subdued, made simple in its
