Children outdoor playground and play equipment have been innovative in design and interaction in recent years. Multiple pieces of research attempt to use technologies to refresh play and activities experience in playground. The article focus on an IoT playground project about technological-enhanced artefacts installed and located in Magistratshagen, Linköping. This study investigates how do technology-enhanced artefacts actively attract and engage children in the playground. Specifically, actively attract and engage means the artefact invites players and sustains their attention on the activities. Research through design is used to study the behaviour of our participant. Previous observation data are used to give an initial idea of playground structure and play activities. After the analysis, on-field observation was conduct in the Magistratshagen playground. A visual and audio based scenario design is created to gather more data on attracting attention. The result showed that audio and visual element has a significant advantage on grabbing player’s attention. However, the visual and audio effect in the design fails to keep participants’ attention. The concept of social interaction should be considered when we are designing attracting and engaging interaction for playground artefact.
