Attention Heatmap report

The Heatmap displays the most attractive elements of the image for viewers in the form of "hot" and "cold" spots creating so called heat map.
The report is displayed as a color gradient overlay on the original image.
The heatmap highlights areas likely to receive attention within the first few seconds.

Use the Heatmap report to:
Visualize which elements attract more attention than others.

Interpreting the results:
The Attention Heatmap report is a predicted eye tracking report of 40 viewers which show how areas of the original image attract the attention.
The heatmap colors range from green through yellow to red. The colors are representing low, medium and high levels of attention, respectively.
Areas with no color imply that this area will be over looked.

Gaze Plot report

The Gaze Plot report visualizes the scan paths and order between elements inside the image.
It displays movement sequence, order and duration of gaze fixation.
The report is made of a series of short stops (fixations) and fast movements of an eye (saccades).
A Gaze Plot report is also referred to as Scanpath report.

Use the Gaze Plot report to:
Visually demonstrate fixations order and gaze paths.

Interpreting the results:
Fixations are marked with circles along with a number that state the order in which the eyes move between fixations.
The average saccade between each fixation is 250 milliseconds.
The report present up to 30 fixations in 3 groups of colors: red (0-2.5 seconds), yellow (2.5-5 seconds) and green (5-7.5 seconds)
The gaze point size is corelated with the heatmap visibility score.

Opacity Map report

The Opacity map report tones down information that is not attractive and visually displays what your viewers may perceive during the first few seconds of visual inspection.
The Opacity map report uses a transparency gradient.
Opacity Map report is also referred to as Focus Map report

Use the Opacity report to:
Emphasize which areas are being perceived and which are being ignored.

Interpreting the results:
The opacity shows the parts of the media with the highest counts or longest fixations and shades the rest of the media.
The most transparent areas are those that attract more attention.

Areas of Interest report

The Areas of Interest report (AOIs report) reveals a score of the predicted probability that a person will look at the area along with detailed diagnostics to show why the region is likely to get attention.
An Area/Region of Interest (AOI/ROI), is an edited area where the metrics are calculated such as visibility score, time to first fixation, fixations count etc'.
You can click and drag boxes to create AOIs surrounding specific areas inside your stimuli.
Tagging these areas allows the analysis engine to output AOI statistics for the Fixations & Visual Features

Use the Areas of Interest report to:
  • Define areas inside the image to determine the Visibility Score of this area.
  • Every AOI is reported with detailed data about fixations and visual features.
  • Compare results between different versions of your design and layout.

Interpreting the results:
The Visibility Score is a summary metric that indicates how salient are the visuals inside this region. The score is calculated based on the highest heatmap value found inside the AOI region.
The value is the probability of having a visual fixation within first 3-5 seconds inside this AOI region.
0% means no attention at all, and 100% means this area will be mostly noticeable.
Areas of Interest is also referred to as Regions of Interest (ROIs)
Most attention is located at areas with more or longer fixations.

To generate an AOIs report, Click on "Add Area" to add a new AOI area.
Resize and move the AOI area to adjust its location and dimensions.
Click "Analyze" to update the AOIs report with the latest AOIs details.

Fixations & Visual Features

This table holds the Fixations and Visual Features data for each Area of Interest (AOI).


Visibility Score (%) - The percentage of participants that fixated at least once within an AOI.
The score is calculated based on the highest heatmap value found inside the AOI region
also referred to as "Participant percentage" and "Seen By (%)"
Time To First Fixation (ms) - The time in milliseconds from when the stimulus was shown until the start of the first fixation within an Area Of Interest (AOI).
also referred to as "Time Until Noticed"
Fixations Before (n) - The number of fixations before the participant fixated within an AOI for the first time.
Fixation Length (ms) - The length of the fixations in milliseconds within an AOI.
Fixation Count (n) - The number of fixations within an AOI.
Visual Features

Visual Features are major contributors to the calculation of AOI score.
Drawing attention requires the object to have a significant contrast from surrounding objects and background.

Interpreting the results:
If the AOI score is low, not visible enough, and you wish to increase the score and make the object more prominent, the visual features gives you cues about how to achieve that.
Inspect which visual feature of this AOI is low and change its design to make it higher.
Design change can be done by changing color contrast (red/green or blue/yellow), intensity (dark/light), orientation (change angle of the object), adding or reducing edges, adding or removing face.

Intensity Features - The percentage level of intensity.
Edges Features - The percentage of edges, texture and orientation.
Red Green Contrast - The percentage of Red-Green diffrence.
Blue Yellow Contrast - The percentage of Blue-Yellow diffrence.

Improving the results:
A high conotrast between an element and its surrounding will increase the element's visibility.
Measure the color contrast of an AOI element and alter it to reduce or induce its visibility.
  1. Identify the dominant color of the element (foreground) and the dominant color of its surrounding (background).
  2. Measure the color contrast ratio of the two colors.
  3. Change the element or its background luminance to increase or decrease the color contrast ratio.

Color Contrast ratios can range from 1 to 21 (commonly written 1:1 to 21:1).
Minimum contrast for reading text is 4.5:1
The contrast of black foreground over a white background is 21:1

Aesthetics report

Aesthetics report enables you to examine the emotional aspects of aesthetics.

Based on several large scale studies with millions ratings of visual appeal collected from nearly 10 thousand participants, we developed computational models that accurately measure the perceived visual complexity and excitingness.
  • Viewers will judge design as beautiful or not within 1/50th to 1/20th of a second.
  • Visually complex designs are consistently rated as less beautiful than their simpler counterparts.

Excitingness Score
How exciting and colorful is the design.
The value ranges from 0 to 100.
A high score means that the design is exciting, interesting and colorful.
A low score means calm and dull design.

Improving the results:
There is no right or wrong in high or low score value.
Many successful websites have calm design and get a low Exciting score.
A high Excitingness value for websites is above 25 and for Ads is above 50.
Exciting is more related to colors and how vivid and rich the visual is. Clarity is mostly not affected by Exciting. Clarity is the opposite of clutter and clutter is created by textures and noise.
When Exciting reach above 85, it could affect Clarity, if there are large amount of contrasting elements and not enough white space.

Clarity Score
Clarity is the opposite of Complexity.
Ratings of appeal are significantly negatively affected by an increase in visual complexity. The more complicated the stimuli is, the worse the people perceived it's attractive.

The value ranges from 0 to 100.
A high score means that the design is clean, simple and clear.
A low score means highly confusing, complex and cluttered design.

Under 25 is bad and clutter. For example, LingsCars webpag.
Between 50-75 is a good. For example, Nike webpage.
Above 75 is excellent. For example, Xiaomi and Apple webpage.

Improving the results:
Some designs are less clear than others simply because they contain less content.
You should aim to increase clarity. Clear design reduces cognitive load and ensure that the viewers will see what you want them to see.

To improve clarity, you need to reduce clutter:
  • Reduce unnecessary text.
  • Use more images. Human perception of clutter is much more forgiving of imagery than of text.
  • Increase the amount of whitespace or padding around content.
  • Use images with less texture and fewer lines.
  • Organize the design into easily distinguishable content blocks.
  • Reduce number of tasks user has to perform.
  • Reduce amount of information user has to keep in mind.

Balanced Score
The value ranges from 0 to 100.
A high score means that the design is symmetrical, balanced and harmonic.
A low score means unbalanced and asymmetrical
The cyan grid demonstrates color balance.
The magenta grid demonstrates intensity balance.
A good balance value is above 60

Improving the results:
  • Compartmentalize your design by using grids.
  • Pick two or three base colors at most for your design.
  • Make elements stand out by adding white space around them.
  • Consistent fonts and typography
  • Have all elements connected
