Gillian Hayes (pictured), informatics assistant professor, designs computerized devices that help teachers work with children who have autism. One device, called Selective Archiving, records video of a classroom. If a child with disruptive or dangerous behavioral tendencies acts up, the teacher presses a button to save that section of video, as with TiVo. He or she can then watch the recording after hours, when there are fewer distractions. Another device, Visual Scheduler (vSked for short), takes children with autism through exercises in which they identify the day of the week, the month, the weather outside and other things a teacher might ask in a typical elementary school classroom. On a handheld touch screen, they press a button to choose an answer. If they pick the wrong one, the correct button shakes and turns colors, eliminating the need for a teacher to physically point to the right answer.
