Video voting examples
The video that the class watched
The class held up yellow cards when they perceived that the motion on the screen had been produced by physically moving the camera around. The class held up blue cards when they thought the motion was the product of panning or zooming the stationary camera.
The class watched an especially dramatic scene from the movie Once Upon a Time in the West.

The same video with bar graphs showing the class' votes at every point in time
Please see this page for an explanation of how the relative number of cards held up was measured.

Distance-corrected, yellow-thresholded U plane
This video of the class voting shows the pixels that were detected to be yellow. Pixel brightness corresponds to distance away from the camera, which ensures that far away cards (which appear smaller) get counted equally with close up cards.
