How children's technology is developed, and who is involved in the process, can vary greatly. While there are many roles children can play in the design of new technology, at the University of Maryland we have focused on partnering with children ages 7-11. We have found these intergenerational partnerships can lead to unexpected technology innovations, as well as establishing design methods for working with children. Influenced by the cooperative design practices of the Scandinavian countries, and participatory design and contextual inquiry in the U.S., we have developed design methods for working with children called Cooperative Inquiry [3,4].A case study illustrates how even young children can contribute to the technology design process.
