The effect of increasing distance of external focus and preference on performance accuracy in dart throwing
The present study examined the effectiveness of distal versus proximal external foci of attentions a function of performers’ preferences for a certain focus. dart throwing task were used, and participants (N=20) were instructed to direct their attention either to the target (distal focus) or the flight of the dart (proximal focus). Participants were asked to select their preferred focus aft...
متن کاملDart Throwing on Surfaces
In this paper we present dart throwing algorithms to generate maximal Poisson disk point sets directly on 3D surfaces. We optimize dart throwing by efficiently excluding areas of the domain that are already covered by existing darts. In the case of triangle meshes, our algorithm shows dramatic speed improvement over comparable sampling methods. The simplicity of our basic algorithm naturally ex...
متن کاملAlgorithms for localized dart-throwing
How does one “throw localized darts,” that is, place random points in a subregion? It is inefficient just to find points in a larger region, only to check painstakingly every generated point for subregion membership. We describe herein several means for efficient, localized dart-throwing, under the constraint that a subregion’s points be entirely consistent with a restriction of any larger gene...
متن کاملQuiet Eye Changes under Environmental Constraints During Performance Target Launcher Skills
The ability to direct the gaze to optimal areas in the environmental context, at the appropriate time, is central to success in all sports. The aim of this study was to changes determine the elements of QE, during the run a reactivity launcher targeting skill, under different environmental demands. That was done to identify perceptual - cognitive effects performance-based infrastructure process...
متن کاملOptimal Control under Stochastic Target Constraints
We study a class of Markovian optimal stochastic control problems in which the controlled process Z is constrained to satisfy an a.s. constraint Z(T ) ∈ G ⊂ R P − a.s. at some final time T > 0. When the set is of the form G := {(x, y) ∈ R × R : g(x, y) ≥ 0}, with g non-decreasing in y, we provide a Hamilton-Jacobi-Bellman characterization of the associated value function. It gives rise to a sta...
