The purpose of this paper is to investigate how young children associate materiality and meanings and how it can benefit tangible interaction design. To study this, we developed a research prototype, Stampies that allows playful tangible interactions. Stampies consists of tangible objects made out of different materials (wood, felt, silicone, and plastic) and an iPad drawing application. We describe results from our empirical study involving 19 children aged 4 to 7. The study indicates that children associate materials with meanings through "material essences", feel, and tactile preference. We conclude with design implications for tangible interaction for children.
The purpose of this study is to investigate the role of materiality in tangible interaction design for children. We specifically target children aged 4 to 6 years old because of societal trend of early exposure to touch screen devices for children. This study compares three types of material (felt, wood, and plastic) for tangibles along with touch-based interaction and how the differences implicate child art creation on an iPad application. Through mixed-methods analysis of twenty-six participants' experiences, we use data sources of video recordings, drawings, and interview. The main finding looked at the hardness of materiality for physical and digital drawing tools and its influence to digital art drawings. The findings from this study may be applied to design tangible user interfaces for young children.
Abstract:This study uses eye-tracking to investigate the differences in the way professional astrophysicists and novices observe simulations of galactic events. The results of this study provide insight into which aspects of the data are important and allow us to tailor the visualizations for a specific group. We hypothesized that the gaze patterns of professionals and novices would vary considerably. A user study was performed on two groups: trained astrophysicists and novices. Each group was presented with a randomized sequence of images and a video while their gaze patterns were recorded with an eye-tracker. We discovered that although both groups observed each image for the same duration, experts limited their fixations to a smaller area. Novices, on the other hand, had fixations which were spread across the images. For the video, the astrophysicists were more focused on simulations in which most of the data was visible and the camera angles had minimal axis change.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
