Good visual perception skills are important in the effective manipulation of Tangible User Interfaces. This paper reports on the application of a test set we have developed specifically to quantify the visual perception skills of children when matching a physical object to its flat representation on paper. A pilot evaluation, with two groups of children(More)
The study of expertise in surgery aims to facilitate the development of improved training methods by understanding the characteristics of expert practitioners. In this article and its companion, we present our study of the characteristics of competence and expertise in the field of oral surgery. We observed participants of different skill levels as they(More)
The angular distributions and the partial branching fraction of the decay B0 → K*0 μ+ μ- are studied by using an integrated luminosity of 0.37  fb(-1) of data collected with the LHCb detector. The forward-backward asymmetry of the muons, A(FB), the fraction of longitudinal polarization, F(L), and the partial branching fraction dB/dq2 are determined as a(More)
PURPOSE In the present study, the authors aimed to investigate the language confounds of filtered words tests by examining the repetition of real words versus nonsense words as a function of level of filtering. METHOD Fifty-five young, native-English-speaking women with normal hearing were required to repeat 80 real-word and 80 nonsense-word monosyllables(More)
—Clustering is the act of grouping items that belong together. In this paper we explore clustering as a means to construct tangible program logic, and specifically as a means to use multiple tangible objects collectively as a single tangible program parameter. We introduce T-logo, a simple tangible programming environment developed to test the concept of(More)
And so the supply chain is constituted: total strangers exchanging virtual objects for real-world objects. My 85-year-old uncle, Charles Keegan, used to enjoy his home entertainment system, including a television set. Unfortunately, his eyes have now succumbed to macular degeneration, an age-related illness characterized by a detached retina leading to(More)
