Clari-Fi

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

 

Pro version of assessment tool (beta trial)

This page applies a calibrated level of Gaussian blurring to a screenshot of an interface that is intended to be viewed on a laptop, in order to help evaluate the clarity of the visual features. The default level of blurring is calibrated to simulate a 13" laptop.

Screenshots must be captured from a screen that is 1920x1080 resolution, with no zooming or display scaling.

The size of the screen that is used to capture the screenshot does not matter.

Initially, this tool will run in ‘free demo’ mode, which will add watermarks to the images. These watermarks can be removed by entering a licence key, which can be purchased by emailing software@enterprise.cam.ac.uk.

By default, this tool uses a level of blurring that corresponds to a simulated laptop size of 13", at 1920x1080 resolution and 40 cm viewing distance. The drop-down menu below can be used to change the screen size of the laptop that is simulated.

Get started by using the ‘Choose files’ button below to select any number of image files. The images will be processed locally by your computer; they are not transferred over the Internet.

When viewing the blurred versions of the images, they should be presented at a reasonably large size, such that moving closer or further away from the screen doesn’t make any difference to the details that can be perceived.

This functionality has been launched as a beta trial. If you have any feedback on this new functionality, please send it to edc-toolkit@eng.cam.ac.uk
