Improving Target Acquisition for Computer Users With Athetosis.
Prior work has highlighted the challenges faced by people with athetosis when trying to acquire on-screen targets using a mouse or trackball. The difficulty of positioning the mouse cursor within a confined area has been identified as a challenging task. We have developed a target acquisition assistance algorithm that features transition assistance via directional gain variation based on target...
متن کاملPop-up depth views for improving 3D target acquisition
We present the design and experimental evaluation of pop-up depth views, a novel interaction technique for aiding in the placement or positioning of a 3D cursor or object. Previous work found that in a 3D placement task, a 2D mouse used with multiple orthographic views outperformed a 3D input device used with a perspective view with stereo. This was the case, even though the mouse required two ...
متن کاملDesigning Contents for a Serious Game for Learning Computer Programming with Different Target Users
In recent years, all over the world, students are less interested in science, especially in computer science where the number of students is shrinking. Also, 50% or more students who initially choose computer science soon abandon the study. Hence, it is essential to attract students to learn computer science, in particular computer programming, via non conventional teaching approach. A promisin...
متن کاملAthetosis *
Although several varieties of tremor were known to the ancients, involuntary mobile spasm appears to have remained unrecognized as a physical disease until modern times. The "dancing sickness" of the Middle Ages seems to have been a purely psychic epidemic.7 Parkinson20 quotes Linnaeus and Vogel as establishing the dassification of Hieranosos: Corporis agitatio corntina, indolens, convulsiva, c...
متن کاملChoreo-athetosis with severe thyrotoxicosis.
Introduction Fasting plasma tyrosine is raised in hyperthyroidism (Hall, Anderson and Smart, 1969) and serum magnesium levels are low in severe thyrotoxicosis (Marks and Ashraf, 1978). Although tyrosine hydroxylase is the rate-limiting enzyme in the metabolism of tyrosine it is conceivable that more dihydroxyphenylalanine is formed under these conditions which may give rise to choreiform moveme...
