Using the Matlab Signal Processing Toolbox, we analyzed the eye trajectories offline and evaluated the task performance of the subjects.
Here we will suggest that the equi-affine metric might be more appropriate than the Euclidean metric for describing the neural code subserving the representations of arm (and perhaps also eye) trajectories.
Data analysis was conducted in two trajectories: In the "bird's eye view" trajectory we used a "feature" unit of analysis to illustrate how learning was supported by features designed according to the two design-principles in each of the courses.
Because the path graph consists of vertices and the edges between them, it approximates the real scan path of eye movement trajectories.
The current focus of visual attention can affect eye movement trajectories (Sheliga et al., 1995), even when saccades are elicited via stimulation of the superior colliculus (Kustov and Robinson, 1996).
For instance, compensation for the delayed visual response of the eye to the trajectory of a moving object occurs in the retina rather in the visual cortex.
Once the men exited, the women retreated to the wall again, and, standing side by side, moved from shape to shape, never in unison, until suddenly they both stopped in identical positions, the left hand behind the head and the straight right arm raised toward a high horizon to the side, their eyes following that trajectory.
Because of the transparency of the matrix, the morphology of the hydrofracturing cracks can be identified by the naked eye observing the trajectories of the tracer.
In fact, the two-thirds power law, initially discovered for hand movements, was later found to describe many other body movements such as foot trajectories, eye and speech movements and human locomotion [49].
People without brain injury are able to track the moving object with smooth pursuit eye movements and correct trajectory.
