Visual Perception Analysis with GazeHits

10,335 views

Published on

GazeHits is a design assistant tool to know how your design is perceived in terms of visual attention. It bases itself on state-of-the-art visual attention computer models to identify the elements and features that captures attention.

GazeHits makes easy to analyze alternative designs and decide when a work is ready to present it to your customer.

Visual Perception Analysis with GazeHits

  1. 1. Visual Perception Analysis with GazeHits
  2. 2. 2
  3. 3. Visual perception analysis 1. What is GazeHits 2. GazeHits for conversion optimization 3. Science behind 4. Technology under GazeHits
  4. 4. ● Qualitative − Expert opinion ● Eye tracking − Is costly and time consuming − Requires hiring tens of people to acquire reliable data − Does not trace the drivers of attention CC BY 2.0 SMI - Neil Rickards Conventional visual perception analysis
  5. 5. GazeHits, beyond eye tracking ● Immediate and Mobile ● Predicts first 3 seconds of eye tracking with high accuracy ● Predicts visual clutter perception with high correlation (0 to 100) ● Provides insight in why something is eye-catching or cluttered ● Provides quantitative indicators to be integrated with analytics
  6. 6. Importance of visual perception in marketing ● “If consumers’ attention is not caught in the first place, all findings [on message appreciation and acceptance] in ‘forced exposure’ research are valueless.” Wedel and Pieters. Review of marketing research. (2008): 123-147. ● “The density of visual detail in terms of color, luminance, and edges hurts brand attention and attitude toward the ad” Pieters, Wedel, and Batra. "The stopping power of advertising: Measures and effects of visual complexity." Journal of Marketing (2010): 48-60.

  15. 15. ● Acquires 10-100 Mb/s through retinal photoreceptors ● Our eyes move all the time: Saccades and Fixations − Otherwise photoreceptor adaptation would make us blind in seconds ● Just one degree of visual field is perceived with high acuity at a time − That part under the spot of the Fovea ● Certain stimuli receive enhanced neural processing ● Fixations − Keep the fovea around a fixed point during 0.5s − 2-3 fixations per second 4 facts about human visual system...
  16. 16. What is visual attention? ● Roughly, the set of operations that select visual information ● Key role in − Building visual concepts to represent reality − Object perception − Focusing cognitive effort on important stimuli
  17. 17. ● Biases of the visual system: e.g. looking at the center − Unrelated to the specific image ● Top-down Relevance related to task, intention, and knowledge of observer − Dependent on observer motivation and experience, generally divergent ● Bottom-up Saliency arising from the physical features of the scene − Universal and common to any observer with healthy vision What are the drivers of attention?

  20. 20. Models of attention ● Bioinspired − Decompose and analyse images following observed operations in the human visual system − Implement hypothesis on neural operations ● Traceability is possible ● Robust performance across different types of images ● Unaware of semantics or task ● Machine learning − Learn to reproduce fixations registered in eye tracking experiments ● Capable to learn semantics and task-related behavior ● Reproduce biases in training data set ● Black box. No traceability
  21. 21. AWS, the model under GazeHits ● Based on the image representation by the visual cortex − Hubel and Wisel, Nobel Prize of Medicine 1981 ● Based on statistical operations shown by the human visual system − Decorrelation and normalization contrast
  22. 22. Technology under GazeHits ● AWS as the bioinspired component − Accurate and robust to biases and changes in image types − Ranked first with sAUC (no biases) in MIT CAT2000, the largest benchmark available ● Machine learning used for task-related prediction − Can be trained with conventional analytics data
  23. 23. Competitors ● Feng-Gui (https://www.feng-gui.com/) − Based on some kind of algorithms ● Attention Wizard (https://www.attentionwizard.com/) − Based on algorithms to provide web heatmaps ● Eyequant (http://www.eyequant.com/) − Based on machine learning (only for webs) ● 3M Visual Attention Service (http://solutions.3m.com/wps/portal/3M/en _US/VAS_NA/Home/)
