Abstract — The Augmented Knight’s Castle (AKC) comprises traditional play figures and scenery embedded with radio frequency identification (RFID) technology to enhance user experience by triggering various forms of audio output. In this paper we present the results of a user study with over 100 children to evaluate the AKC in terms of playful learning, compared with an identical, non-augmented version. Findings suggest that children who played with the AKC remembered facts about the Middle Ages that were presented to them in the form of verbal commentaries, both immediately after the play session as well as in a post-test two months later. with one 3x4cm antenna. In total, the play set featured nine active zones (9 readers, 3 multiplexers, and 22 antennas).

An Augmented Knights Castle (AKC) play set was adapted so that children with autism can configure programmable elements. This is compared with a non-configurable AKC and when the AKC set is switched-off. When the system is configurable, and when it is switched on, less solitary play and more cooperative play occur. Digital toys, and their configurability are key factors in design for children with autism allowing greater individual control and more socially oriented behaviour. We suggest that tangibles provide a safety net for encouraging social interaction as they allow for a broad range of interaction styles.
