Building interactive, intuitive interfaces for children: how the Sugar environment drew inspiration from research presented at HVEI

Abstract: UNESCO estimates that eleven percent of primary school–age children—seventy-two million worldwide—are not enrolled in or attending school. Children who do attend may find themselves in schools that lack adequate space, facilities, or resources—impossible situations for learning. It is against this backdrop of profound need that One Laptop per Child (OLPC) emerged in 2005. The mission of the organization is to “empower the children of developing countries to learn.” We created the first affordable netbook, specifically built to withstand harsh climates and the handling of young children and the Sugar software tools, uniquely designed to help children educate themselves. The hardware and software development was inspired by learning research of Seymour Papert, but also by the research community represented by the HVEI conference. From the beautifully efficient transflective display designed by Mary Lou Jepsen, to the use of color in the desktop designed by Red Hat and Pentagram, to the learning activities in which the children directly engage, consideration was given to convergence of our expanding knowledge of the human visual system and advances in engineering and signal processing. This talk will touch on the variety of ways in which OLPC and Sugar Labs have been touched by HVEI and have subsequently touched the lives of millions of children around the world.
