You will rate a pair of 3D abstract objects based on how similar they are for you. Using the keyboard keys, you can choose from 1 (not similar at all) to 5 (extremely similar). You will be asked to do this as quickly and as accurately as possible.

This task is one (1) in a group of three (3) similarity-rating tasks. The other two (2) will show you the same group of objects, but rendered with different depth cues each.

Thank you for your participation and good luck!
