متن کاملTrajectory prediction of saccadic eye movements using a compressed exponential model.
Gaze-contingent display paradigms play an important role in vision research. The time delay due to data transmission from eye tracker to monitor may lead to a misalignment between the gaze direction and image manipulation during eye movements, and therefore compromise the contingency. We present a method to reduce this misalignment by using a compressed exponential function to model the traject...
متن کاملFourth Purkinje image signals reveal eye-lens deviations and retinal image distortions during saccades
Saccadic eye movements of various sizes and directions were registered simultaneously with the scleral search coil and a fifth-generation Dual Purkinje image eyetracker. Comparison of the search coil and the Purkinje image tracker records reveal considerable dynamic deviations during and immediately after the saccade, which we ascribe to the movements of the eye lens relative to the optical axi...
متن کاملThree Dimensional Ultrasonography of the Eye and Measurement of Optical Nerve Sheet Diameter in Dog
Objective- To determine the possibility of three-dimensional ultrasonography (3DUS) and measurement of optical nerve sheet by this method. Design- Descriptive study. Animals- 10 mixed normal dogs (5males, 5 females), age 1-1.5 year, and weighting 15±5 kg Procedure- 3D ultrasounds of the eyes were evaluated and the normal optical nerves in 3DUS images were measured using Volouson 730 pro....
متن کاملWhy have microsaccades become larger? Investigating eye deformations and detection algorithms
The reported size of microsaccades is considerably larger today compared to the initial era of microsaccade studies during the 1950s and 1960s. We investigate whether this increase in size is related to the fact that the eye-trackers of today measure different ocular structures than the older techniques, and that the movements of these structures may differ during a microsaccade. In addition, w...
