Feng-GUI is a free web based service that enables you to view: “which areas of an UI is getting the most attention when an user looks at it in 5 seconds”.

With an artificial intelligence behind, the service generates a heatmap over an image uploaded.

Generated heatmap’s opacity can be changed for a better view & can be viewed in a bigger modal window or downloaded.

Feng-GUI is very handy to get another thought -about a user interface designed- other than the collagues, customers..
