Science & Quality

Feng-GUI reports closely (92%) resemble a 5 seconds eye tracking session of 40 people.

Feng-GUI analysis employs dozens of algorithms from neuro-science studies of natural vision processing, computational attention, eye-tracking sessions, perception and cognition of humans.

How accurate is it?

Feng-GUI algorithmic model incorporates live eye tracking results. This makes our analyses as accurate as live eye tracking (92%) MIT approved – at a fraction of the cost. The analysis resembles a 5 seconds eye tracking session of 40 people.
Since 2007, We measure, benchmark, compare and tune the analysis with eye-tracking data sets. The data sets contains millions of data points across tens of thousands eye-tracking experiments.

  • Cutting edge: our algorithmic model is regularly updated
  • Precise: algorithms informed by latest live tracking results
  • Accurate: not skewed by test conditions and unreliable subjects

The science behind Feng-GUI

Cognitive science deals with how the brain works. It helps us to understand how people perceive and process external stimuli. An understanding of basic cognitive principles is essential in analyzing how your users perceive, process and respond to your design. Each of the reports highlights an aspect of user brain activity and demonstrates how cognitive principles can be applied to your design to ensure they are communicating effectively.

Our testing methodology is based on over 50 years of scientific research.
  • Live eye tracking: analyzing the eye paths of actual users through webpages
  • Neuroscientific research: how the brain analyzes data
  • Cognitive science: how human behaviour affects our perception of visual design
visual features examples

Video analysis detects additional visual features such as: flicker and direction and velocity of motion between frames.

Test and Tune

We measure, benchmark, compare and tune the analysis with public eye tracking data sets.
The data sets contain thousands of images viewed by hundreds of participants.
Massachusetts Institute of Technology (MIT), the best university of technology in the world, has reviewed the accuracy of Feng-GUI attention algorithm as part of its Saliency Benchmark. read more...
