Coordination of eye and finger movements in copytyping
نویسنده
چکیده
Eye movements and manual keypresses of one high-skilled typist were analyzed to determine eye-hand span, viewing time, and typing time for word and letter units. The results revealed a relatively small eye-hand span of 2.4 character spaces. Fixation time and typing time were positively correlated when word and letter units were analyzed. However, the correlation accounted for 79% of the variability (r = .89) when word units were analyzed and for only 29% of the variability (r = .54) when letter units were analyzed.

Coordination of gaze and hand movements for tracking and tracing in 3D.
In this study we have investigated movements in three-dimensional space. Since most studies have investigated planar movements (like ellipses, cloverleaf shapes and "figure eights") we have compared two generalizations of the two-thirds power law to three dimensions. In particular we have tested whether the two-thirds power law could be best described by tangential velocity and curvature in a p...
متن کاملIntermanual coordination in relation to handedness, familial sinistrality and lateral preferences.
Intermanual coordination assessed by alternating finger tapping and finger-tapping asymmetry were investigated in 105 healthy right- and 105 left-handers and related to handedness, familial sinistrality and lateral preferences (in hand-clasping, arm-folding and eyedness). Compared to right-handers, left-handers with less pronounced left-hand preferences (Subgroup B) showed higher values in inte...
متن کاملEnucleation of Eye Using Finger Following Cannabis Consumption
Background: Enucleation is a topic discussed in psychiatry which is a self-injury matter. Enucleation is observed as psychotic disorder due to substance abuse. In people with mental disorders who also have substance use leading to hallucinations and delusions, unusual eye evacuation were reported. In most cases, enucleation was done using sharp tools. Case Report: This report describes a man su...
متن کاملLRP predicts smooth pursuit eye movement onset during the ocular tracking of self-generated movements.
Several studies have indicated that human observers are very efficient at tracking self-generated hand movements with their gaze, yet it is not clear whether this is simply a by-product of the predictability of self-generated actions or if it results from a deeper coupling of the somatomotor and oculomotor systems. In a first behavioral experiment we compared pursuit performance as observers ei...
