Children with exercise-induced asthma face several challenges in their daily life, which can improve by proper self-management practices. AIRplay combines biomedical sensing with gamified environments to improve physical conditioning and self-management of asthma among children aged 7 to 9 years old. The goal is to develop a proof-of-concept of coaching application that monitors physical activi...

Six schools were randomly assigned to a multilevel bullying intervention or a control condition. Children in Grades 3-6 (N=1,023) completed pre- and posttest surveys of behaviors and beliefs and were rated by teachers. Observers coded playground behavior of a random subsample (n=544). Hierarchical analyses of changes in playground behavior revealed declines in bullying and argumentative behavio...

This paper describes an empirical study of end-users that tested the usability of The Programmers’ Playground graphical environment. The Programmers’ Playground is a software library and run-time system for constructing distributed multimedia applications. Playground’s graphical environment enables end-users to create direct manipulation graphical user interfaces (GUIs) and to dynamically confi...

OBJECTIVE To determine the use of lead-based paint in public playgrounds in the municipalities of Johannesburg, Tshwane and Ekurhuleni. METHODS Forty-nine public parks were selected from the municipalities of Johannesburg, Tshwane and Ekurhuleni. Lead levels in paint on playground equipment were measured in situ using a hand-held Thermo Scientific NITON XLP 700 Series X-ray fluorescence (XRF)...

Playful interaction in an important topic in HCI research, and there is an ongoing debate about the fundamental principles that underpin playful systems. This paper makes a contribution to this debate by outlining a set of sensitizing concepts which have emerged from an analysis of interaction in the playground; these help explain its appeal to children, and have been selected for their potenti...

Introduction: Children from under-resourced environments often lack opportunities to engage in sensory experiences that support developmental abilities and scholastic performance. “Back Urth” playgrounds were designed address the needs of foundation phase learners communities. A 12-week sensory-motor program, based on Ayres Sensory Integration ® (ASI) principles, was developed, educators traine...

Active Logic Documents (ALD) are web pages which incorporate embedded Prolog engines that run locally within the browser. ALD offers both a very easy way to add click-to-run capabilities any kind of teaching materials, independently tool used generate them, as well tool-set for generating web-based materials with examples and exercises. Both leverage on (components of) Ciao Playground. We prese...

Nanoscale-layered ferromagnets have demonstrated fascinating two-dimensional magnetism down to atomic layers, providing a peculiar playground of spin orders for investigating fundamental physics an...
