Principal Investigator: Ing. Jirí Filip, Ph.D, ÚTIA AV CR v.v.i., filipj@utia.cas.cz PARTICIPANT INFORMATION You are invited to participate in a study conducted by Dr. Jiri Filip (Czech Academy of Sciences). The project has been approved by the Ethics Committee of the Institute of Psychology, Czech Academy of Sciences (Reference Number: PSU-308/Brno/2022). In this study, you will be asked to judge the similarity of presented materials (e.g., wood or leather).

Each trial shows movie of the test material accompanied by all the other materials from the other trials on a smaller scale. 
Below the video, there are 10 sliders corresponding to visual attributes of the material. Your task is to set the sliders position for each material. You may consider the appearance of the other materials to set your rating appropriately within the range we are testing. The following visual attributes are evaluated: 1. Brightness - how bright is the material in comparison with the others? 2. Glossiness - how shiny is the material? 3. Colourfulness - how colourful is the material (in terms of the saturation of the colours)? 4. Directionality - presence of directional structures in the texture 5. Complexity - how complex are the patterns on the surface? 6. Contrast - difference in brightness in surfaces patterns 7. Roughness - smoothness of surface profile, range of surface heights 8. Patchiness/Regularity - how uniform is the pattern 9. Line elongation - are line elements shorter dashes or extended lines? 10. Spatial scale - are patterns large and broad, or small and fine?
