The Method of Adjustment module creates a “carousel” of images, allowing a study participant to move back and forth through the image set as they determine their threshold for the effect under study.

The Round Robin Comparison is used to pairwise compare all images in an array. This module is well-suited to asking which visualization is most effective for a specific task — a set of A vs. B choice comparisons.

A flexible module, the Key Task presents an image and a series of answer keys. The keys can be coded by color or by name/text.
This demo takes you through an example study that asks participants to identify the key closest in color to the color at the center of a set of crosshairs.
