- QES is a software program that isolates the quiet eye in any motor task. It automatically computes the QE location, onset, offset and duration, relative to a specific defined phase of the movement.
- QES accepts gaze and motor videos already syhcnronized using an editing package. Synchronized gaze and motor videos are called Vision-In-Action. QES can also temporarily synchronize gaze video from any eye tracker and to any motor video.
- A common time line is superimposed over the synchronized videos, thus allowing the coding of the gaze during specific phases of the movement
- The video pictured below shows gaze and motor videos of a golfer, performing a chip shot, temporarily synchronized. QES advances the videos so they are synchronized using common cues in both videos (eg. the moment the ball is struck by the club).
- The QES interface (right bottom) shows the common time line, and areas to code the motor phases and the gaze (fixations, saccades, etc).
- It is recommended the motor phases be coded first, with a trial onset and trial offset that are the same for each trial.
- Using the same trial onset and offset, the gaze (fixations, saccades, etc) are entered in order. The location, onset, offset and duration of each gaze is recorded.
- The Data Log (top) keeps track of all coded data for the phases of the movement, and the synchronized gaze.
- The Data is saved as a .csv file that can be uploaded to any statistical package.
