We are conducting this brief, informal experiment to assess the quality of
3D vision (stereopsis) of the general population. Please note that your
participation is completely voluntarily. The request for your email address is only so that we can contact you to request your participation in a possible follow-up laboratory test. Your address will not be shared with anyone outside of the research group conducting this study.
The test itself should only take you a few minutes. At the end of the experiment, your 3D vision or stereopsis score will be calculated and displayed to you, along with some facts about 3D vision.
For further information about 3D viewing, please see this helpful Viewing 3D on TV: Questions and Answers page from the CBC.
