This illusion is called the Ames Room and here are your results. The first four bars are the results of your trials and the last bar is your average. The results are the height of the person on the right as a percentage of the person on the left. If the illusion did not affect your perception, then your results show up as 100%.

Your results are {{ctrl.resultsData.displayAverage}}% {{ctrl.resultsData.text1}} than the correct height. So your results show {{ctrl.resultsData.text2}} impact of the illusion. Most people make the person on the right too short.
