TrackIt

TrackIt is a modular, open source software suite that measures sustained selective attention in children; it was created specifically to investigate mechanisms of sustained selective attention in young children.

TrackIt presents the participant with a grid, with each of the grid locations optionally identified by a background image, and a target object moving on the grid along a random trajectory. Participants are asked to visually track the target and identify the grid location last visited by the target before it disappears. The moving target in this task can be accompanied by distracter objects, also moving along a random trajectory. Target and distractor objects are (optionally) randomly selected on each trial from a pool of 72 unique objects. After each trial, all possible distractor and target objects are (optionally) displayed, and the participant is asked to identify which one he or she tracked.

Free and Open Source

Create your own experiments by editing the source code, check the base TrackIt code for bugs, redistribute it to your friends!

Adjustable Complexity

Different age groups can handle different complexity—adjust the grid sizes, number, type, and speed of distractors, and more!

Full Data Recording

Everything that you (and your participant) see on the screen is recorded in an easy-to-read and easy-to-parse file.

Customizable Experiments

You control the trial length, number of trials, which screens are presented to the user, and which (if any) background images are shown.

User-Defined Framerate

Working on a weird machine with a strange monitor? Working with Tobii? Adjust the framerate to match!
