Quick Models for Saccade Amplitude Prediction
Human Visual System (HVS) exhibits a variety of eye movements: fixations, saccades, smooth pursuit, optokinetic reflex, vestibulo-ocular reflex, and vergence [1]. When a person is sitting in front of the computer screen, usually only fixations, pursuits, and saccades are present. Among those three eye movements, saccades are the fastest movements transitioning the eye between relatively stable ...
متن کاملApplying saccade models to account for oscillations.
Saccadic oscillations are unwanted back-to-back saccades occurring one upon the other that produce a high-frequency oscillation of the eyes (usually 15-30 Hz). These may occur transiently in normal subjects, for example, around the orthogonal axis of a purely horizontal or vertical saccade, during combined saccade-vergence gaze shifts or during blinks. Some subjects may produce saccadic oscilla...
متن کاملQuantitative measurement of saccade amplitude, duration, and velocity.
A method for rapid, accurate measurement of saccade amplitude, duration, and velocity (average and maximum) was developed as a functional test of the extraocular motor system. Recordings were made with a direct-current electro-oculographic system, and data analysis was performed on a laboratory digital computer. Saccade amplitude and duration were found to be linearly correlated in 25 normal su...
متن کاملEffect of saccade size on presaccadic spike potential amplitude.
Presaccadic spike potentials were recorded from electrodes placed at the inner canthus and below the eye in ten normal subjects. The responses to twenty abducting and twenty adducting saccades were back-averaged from the beginning of the eye movement, and separate waveforms were obtained for saccades of 20 degrees, 10 degrees, 7.5 degrees, 5.0 degrees, and 2.5 degrees. The spike onset and peak ...
متن کاملAdaptive Changes in Saccade Amplitude: Oculocentric or Orbitocentric Mapping?
The saccadic system rapidly adjusts the amplitude of refixation movements to visual targets when abnormal postsaccadic errors occur. This is called rapid saccadic adaptation. It is not yet clear whether this form of adaptation produces changes related to oculocentric mechanisms, such as retinal error or motor error, or orbitocentric mechanisms, such as eye or gaze position. These experiments we...
