We’ve all had the experience of walking by something interesting or funny on the street and wishing we had someone to share it with. We think of a perfect joke, but with no one there to hear it, we have to let let it slip away. To answer this desire to share reactions, we designed Imprints. This augmented reality system allows you to leave an impression of your reactions in physical space via text or ghosted 3D figures. Seen on a grand scale, webs of Imprints communicate the culture of a location and allow people to share the small wonders they experience every day.
