Footsteps and Kickback Illusions

{{$t('general.by')}}

Riesen
Demonstration of the footsteps and kickback illusions. Focus on the static red target and watch the rectangle move. It should appear to stop and go on the left half of the screen (footsteps) and undergo sudden jerks backwards upon encountering each black line on the right half of the screen (kickback). Many parameters are available for modulation: Mouse Y: height of moving target for smooth pursuit fixation Mouse X: speed of motion UP/DOWN: height of rectangle RIGHT/LEFT: width of rectangle (changes by one half of column widths on left half of screen each time) ENTER: yellow/blue rect
