NoteLet is a design developed to explore 'peripheral interaction' in a primary school classroom context. NoteLet supports teachers in remembering events in the classroom. When something noteworthy occurs, e.g. when a child is working very well and the teacher wants to communicate this to the child's parents, the teacher can take a picture of the classroom through straightforward interactions on a bracelet. These interactions are quick and can potentially be performed without focused attention.

The NoteLet interactive system consists of a camera located in the corner of the classroom and a bracelet that the teacher can wear around the wrist. When the teacher squeezes her wrist, the camera will take a picture, which is stored with the date and time. On the back of the bracelet, the names of all children are listed. When the area next to a name is touched, not only a picture, but also the child's name is stored. To make it easy to find the right name, girls are listed on the right while boys are on the left, both in alphabetical order. Furthermore, the touch-sensitive areas are overlaid with patches of fabric; fabric with a smooth texture for children in first grade and fabric with a rough texture for children in second grade. This way, both location and tactile qualities of the touch sensitive areas may provide information about the connected child's name. The pictures can be used at the end of every few days when entering observations in the computer.
