While at SEOsmarty I posted the results of my experiment with 5 second usability test, here I am looking at another usability tool that may turn useful for your website testing: Feng-Gui that is claimed to show you the heat map of any image you submit.

Here is how the heatmap of SEOsmarty.com looks:

According to their FAQ:

The Feng-GUI heatmap service is an automatic alternative to eye-tracking. Unlike eye-tracking or click-based heatmaps, Feng-GUI creates heatmaps based on an algorithm that predicts what a real human would be most likely to look at.

Simply put, the algo is based on:

• color;
• orientation;
• density, contrast;
• intensity;
• size;
• closure;
• curve.

The tool is also claimed to be 70% as accurate as Eye and Mouse Tracking.

I never did any eye-tracking research for SEOsmarty.com, so I can’t compare but clicking through their recent submissions, I do find the tool worth checking.
