Application settings:
Task time in minutes: Total task time (units: minutes)
Stimulus generator type: Random Repetitive Mixed The Random generator uses 2 simple movements: moving along the arc and moving along the line. As soon as it reaches the end of the arc/line, a new random line/arc is generated.
Size of target:x-small small medium large x-large 6%
The size (radius) of the target depends on the size of your screen. It is expressed as a percentage of the width (height) size of your screen. If you use a higher resolution screen, the target will be larger and vice versa.
Speed of target:The speed of the moving target (circle) on the screen. Set a higher value for faster target movement and vice versa.
If you set the speed too high, the target may start to flicker or may "freeze" in almost the same position, especially if you use a low-resolution screen. Test the speed and adjust it to your screen resolution.
Change movements type (path) each X seconds (minutes):5 seconds 10 seconds 15 seconds 20 seconds 30 seconds 60 seconds (1 min) 120 seconds (2 min) 180 seconds(3 min) 300 seconds (5 min) The type of movement (path, trajectory) of the target will change approximately every 10 seconds
This parameter defines how often the target path will change. This is more important when using a Repetitive Stimulus Generator. It reduces or increases the monotony, ie the predictability of the target trajectory. Eg. if you set it to 120 seconds, and the sinusoidal movement of the target is displayed, the same (virtual) sine curve will be drawn for 2 minute (monotonous and easily predictable trajectory). If you set it to only 5 seconds, and you use low speed and have a high resolution screen, sinusoidal motion will not be fully realized. It is difficult to suggest an optimal value because it depends on many other parameters (speed, generator, resolution, task time).
Demo mode:On
When performing real-world research, turn off demo mode, as it partially slows down the application. When demo mode is on, if the mouse pointer is over the target, it is blue. When the mouse pointer is not over the target it is red. When the demo mode is turned off, the user does not receive any feedback.

Legend for columns in the group research table:
result = Percentage of successful target tracking.
time-s = Measured task time in seconds. This is a control variable. This time can sometimes be greater than the time you set in the options (time-m). It should be approximately valid: time-s = 60 * time-m.
error-r = If this number is greater than zero, the page resized during task execution. Must be 0 for results to be valid.
error-i = Shows how many times the target was partially or completely out of the visible part of the screen during the task. Must be 0 for results to be valid. If it is greater than zero, the most common reason for this is resizing the window during the task.
"-m" = units are minutes. "-s" = units are seconds.
