Clari-Fi

Clari-Fi uses blurring to simulate the challenges of viewing small icons, images and text on mobile screens

 

Clari-Fi helps to evaluate the visual clarity (i.e. perceptibility) of icons, images and text that are intended to be viewed on a mobile device. Clari-Fi speeds up the process of designing these graphical features, because it enables the visual clarity of these features to be evaluated on a large screen device, and uses blurring to simulate the challenges of viewing these features on a mobile device.

Before any new or updated e-commerce images are sent to retailers, Unilever now requires that these images must pass the ‘Clari-Fi’ visual clarity test. This takes less than a minute, and we have used Clari-Fi to test at least 20 thousand Unilever product images.  ”

The level of blurring that's applied by Clari-Fi is calibrated to survey data that was gathered using a handheld test card, so the design team can be confident that if their graphical features appear 'easy to see' in the blurred version of the image, then the vast majority of their users will find these features 'easy to see' on their mobile devices*.

This tool is available separately for mobile screenshots and e-commerce images. A PowerPoint version of this tool is also available to download.

* Clari-Fi considers people who might have difficulty perceiving graphical features because of visual acuity issues. Some people may have difficulty perceiving graphical details for other reasons, especially colourblindness.
