ARCat

Abstract

In this paper we present ARCat, a tangible programming tool designed to help children learn Depth First Search (DFS) algorithm with augmented reality (AR) technology. With this tool, children could use tangible programming cards to control a search process, rather than control virtual characters directly. With the special design of card semantics and real-time feedback, the cognitive load of the learning process had been proved to be affordable to children (ages 8-9) with the result of our preliminary evaluation, which shows the possibility of basic algorithm education for young children with tangible interface.
