Osaka University researchers have developed a text-display algorithm that places the current message on the darkest region in view at any given moment and in a readable color, making wearable displays like Google Glass more usable, New Scientist reports.

This is done using the headset’s camera, which plots a constantly changing heat map of viable on-screen reading locations. The algorithm can also split up a message into two small dark regions either side of your field of view.

The team presented their work  at the Intelligent User Interfaces conference.
