Eye movement was recorded using a table-mounted eye tracker. Smooth pursuit- and saccade-related parameters were calculated from the gaze trace, and the relationships between eye movement parameters and dynamic visual performance were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      DVA was significantly better at 20 dps than at higher speeds (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05 for all comparisons). Eye movement patterns and parameters varied with target velocity, as smooth pursuit dominated at low speeds and saccades became more prominent at high speeds.
