Forehead marker
Using a forehead marker is optional. You may want to this use for participants with only one visible eye, or when using the pupil-only or CR-only gaze estimation method.
Print the marker on sticker paper and cut it out. If you need a forehead marker on a frequent basis it might be desirable to order a roll of disposable marker stickers. See pricing page.
