Pencil Grasp Pattern: How Critical is it to Functional Handwriting? Heidi D. Schwellnus Doctor of Philosophy Graduate Department of Rehabilitation Science University of Toronto 2012 This thesis reports the results of a large study to evaluate the kinetics of pencil grasp patterns in terms of speed and legibility of handwriting of children in Grade 4. Current clinical practice as recent as 2008 ...
iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
When we think about plants, do not normally imagine them “speaking” to each other. But they communicate—in many different ways. More than a century ago, the eminent biologist Charles Darwin suggested that plants have brain-like structure at their root tips! In this case, Darwin’s root-brain hypothesis was wrong, but more modern research shows can communicate. They speak with other as well anima...
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
We have created a unique tool for grasp simulation, visualization, and analysis that allows a user to create and analyze grasps of a given 3D object model with a given articulated hand model. The grasps can be performed either automatically, where the system closes the fingers around the object at preset velocities, or manually through direct manipulation of the joints. As collisions occur betw...
An emerging viewpoint is that the CNS uses synergies to simplify the control of the hand. Previous work has shown that static hand postures for mimed grasps can be described by a few principal components in which the higher order components explained only a small fraction of the variance yet provided meaningful information. Extending that earlier work, this study addressed whether the entire ac...
A multitude of grasping taxonomies have been proposed for grasping actions, [1]. Most of them have been designed heuristically and were never compared or evaluated with respect to how effectively they describe the space of natural grasping motions. Furthermore, they are based solely on the final grasp posture of the hand, leaving out of the picture the approach and retreat phases. In the work p...
the extent to which written corrective feedback on linguistic errors can play a role in helping l2 writers improve the accuracy of their writing continues to be an issue of interest to researchers and teachers since truscott (1996) mounted a case for its abolition. while there is growing empirical evidence that written corrective feedback can successfully target some types of linguistic error (...
A key issue in robotics is the development of the ability to grasp unknown objects. This ability requires a grasp determination mechanism that, based on the analysis of the description of the object, determines how it can be stably grasped. In this paper, a grasp determination method is presented that computes a set of grasps that comply with the force-closure condition. Its input is a set of c...
