Uploading items (stimuli)


With RealEye you can test 3 types of stimuli:

  • images (including screenshots),
  • videos,
  • live websites.

After clicking "New Study" you'll be asked to select your study type:

Then you need to set Study settings and, in the next step, upload your stimuli:


  • images

To add images to your study you may select files from your computer or drag and drop them.

Single study can have up to 100 images (JPEG or PNG, up to 30 MB). Min. resolution of each image is 500 x 500 px and max. resolution is 15000 x 15000 px. You can upload images one by one or a few at once.

NOTE: We recommend uploading images in a resolution of 16: 9 (or similar); narrow images will have a lower "gaze on screen" value, which will cause lower item grade and lower participant grade.
