Saccades and smooth pursuit in myotonic dystrophy
Journal of Neurology, 1999Reflexive saccades, remembered saccades, antisaccades, fixation and smooth pursuit were recorded in seven subjects with myotonic dystrophy (MD) and seven age-matched controls using the magnetic scleral search coil technique. Neuropsychological performance was assessed using the Wisconsin Card Sort Test and measures of verbal fluency.

Towards 3D smooth pursuit interaction
Adjunct Proceedings of the 2019 ACM International Joint Conference on Pervasive and Ubiquitous Computing and Proceedings of the 2019 ACM International Symposium on Wearable Computers, 2019In this position paper, we encourage the use of novel 3D gaze tracking possibilities in the field of gaze-based interaction. Smooth pursuit offers great benefits over other gaze interaction approaches, like the ability to work with uncalibrated eye trackers, but also has disadvantages like the produced visual clutter in more complex user interfaces. We

Smooth pursuit of amodally completed images
Experimental Eye Research, 2019In order to evaluate the effect of the parafoveal area of the retina on smooth pursuit, we compared the horizontal smooth pursuit of visible and amodally completed stimuli in people with central vision loss and controls. In the amodally completed stimuli, a black mask covered the bottom vertex of a moving diamond which is the feature whose movement ...

Smooth pursuit dysfunction in Alzheimer's disease
Neurology, 1988Smooth ocular pursuit was measured by magnetic search coil oculography in 13 patients with Alzheimer's disease and compared with control subjects. Smooth eye movement gain was uniformly reduced in Alzheimer's disease at all target velocities for several frequencies of sinusoidal target motion, signifying impairment of steady-state gain.

Predictive Smooth Pursuit Eye Movements
Annual Review of Vision Science, 2019Smooth pursuit eye movements maintain the line of sight on smoothly moving targets. Although often studied as a response to sensory motion, pursuit anticipates changes in motion trajectories, thus reducing harmful consequences due to sensorimotor processing delays.

Smooth pursuit eye movements in children
Experimental Brain Research, 2005Smooth pursuit eye movements consists of slow eye movements that approximate the velocity of the eyes to that of a small moving target, so that target image is kept at or near the fovea. Little information on smooth pursuit is available in children. We used an infrared eye tracker to record smooth pursuit in 38 typically developing children, aged 8-19 ...

Is perceived motion a stimulus for smooth pursuit
Vision Research, 1982Previous investigations have challenged the generality of the claim that perceived motion in an effective stimulus for smooth pursuit eye movements. The experiments extend the scope of these investigations. Three experiments test the hypothesis that perceived motion can serve as the stimulus for pursuit when the eye movement does not generate ...

Cerebellar role in smooth pursuit movement
Documenta Ophthalmologica, 1977It is generally believed that pursuit eye movements are unaffected by cerebellar cortical atrophy or cerebellectomy. The present study was performed on patients who underwent partial vermis and hemisphere ablations as a result of severe cranial injury or cerebellar tumors. Eye movements were measured by DC electro-oculography.

Bailliere's clinical neurology, 1994
Smooth pursuit is a relatively recent eye movement which has developed in frontal-eyed species. The smooth pursuit system is involved during foveal smooth pursuit, the 'rapid' component of OKN slow phase and VOR suppression. The cortical areas controlling smooth pursuit (at the temporo-parieto-occipital junction and in the FEF) send ipsilateral ...

Real-time binocular smooth pursuit
International Journal of Computer Vision, 1993This article examines the problem of a moving robot tracking a moving object with its cameras, without requiring the ability to recognize the target to distinguish it from distracting surroundings. A novel aspect of the approach taken is the use of controlled camera movements to simplify the visual processing necessary to keep the cameras locked on the
