With all the talk about the Microsoft HoloLens in the news, augmented reality has become a hot topic once again. We've seen some interesting uses, including Aurasma, who took a marketing approach, and Nokia's partnership with Oreo, Oreo Skies. The latter allowed you to explore the stars and leave messages for friends written in the sky.
Taking that concept to a new and far more interesting level is Traces, a mobile app that allows you to leave messages for your friends in the real world. This is very similar to geocaching, in which a physical item is left in a location with coordinates for retrieval. In Traces' case, however, the content is always secure with no chance of being lost or stolen.
When you are within range of a trace, the app displays a directional arrow. If you follow the arrow, you will discover a bubble in the air; hovering on the bubble will reveal the content. It is a really fun and interesting way to make an area more interactive. For example, this could be used by a park to include a walking tour without the need for special hardware.
Traces is currently available for iOS, with other platform support coming soon.
From laptops and Lumia to Surface and Xbox, get it at the Microsoft Store.
