Merry Go Round: a physical, virtual, physical… toy

Publicado em: "ACE 2014 : proceedings of the 11th Conference on Advances in Computer Entertainment Technology". ISBN 978-1-4503-2945-3We present a mixed-reality interface, in which a carrousel-like platform carries a set of wooden figures from the physical world into a game running inside a tablet, bringing them back to the physical world again by further rotating the platform. The wooden figurines allow young children to manipulate and play with them, working at the same time as characters of a game. Along the interaction, users are confronted with different problem solving situations that they can solve with the help of the wooden characters.FCT – Portuguese Foundation for the Science and the Technology within the Projects: PTDC/CCI-COM/119030/2010, and PEstOE/EEI/UI0319/2014.FEDER through the Operational Competitiveness Factors Programme - COMPET

Study of Touch Gesture Performance by Four and Five Year-Old Children: Point-and-Touch, Drag-and-Drop, Zoom-in and Zoom-out, and Rotate

Past research has focused on children\u27s interaction with computers through mouse clicks, and mouse research studies focused on point-and-click and drag-and-drop. However, More research is necessary in regard to children\u27s ability to perform touch gestures such as point-and-touch, drag-and-drop, zoom-in and zoom-out, and rotate. Furthermore, research should consider specific gestures such as zoom-in and zoom-out, and rotate tasks for young children. The aim of this thesis is to study the ability of 4 and 5 year-old children to interact with touch devices and perform tasks such as: point-and-touch, drag-and-drop, zoom-in and zoom-out, and rotate. This thesis tests an iPad application with four experiments on 17 four and five-year-old children, 16 without motor impairment and 1 with a motor impairment disability. The results show that 5-year-old children perform better than 4-year-old children in the four experiments. Results indicate that interaction design for young children that uses Point-and-Touch gestures should consider distance between targets, and designs using Drag-and-Drop gestures should consider size of targets, as these have significant effects in the way children perform these gestures. Also, designers should consider size and rotation direction in rotate tasks, as it is smoother for young children to rotate clockwise objects. The result of the four different touch gestures tasks shows that time was not an important factor in children\u27s performance

Children’s interactions with water in city centres: a case study from Sheffield, UK

Children’s experiences of outdoor environments have been studied now for more than 40 years yet no research has specifically focussed on children’s experiences of water play in constructed spaces of city centres. This article discusses the development of an observational mapping tool, called TOWEC, to record the interaction of children with water. It then reports findings and analysis from observations over a year-long period of 3,399 children interacting with water in the award winning public open space of the Peace Gardens in the centre of the City of Sheffield, UK. The findings reveal that children undertake both active and passive activities associated with the constructed water features and that these activities are influenced by gender, age and temperature, but not ethnicity. The water features were not designed for children to play in but the children realise the potential affordance that the water features provide
