Which files to upload?

Interactive scarf plots

Scarf plots (sequence charts) are a great way to visualise eye-tracking data. They show the order of fixations in time and their hits on areas of interest (AOI). In GazePlotter, they are interactive, customisable and easy to share.

Runs without Internet

GazePlotter does not store your data on a server, thus ensuring data privacy. All is done in your browser. You can use it on PCs, Macs, tablets, even off-line!
