The focus of trolley interactive is on exploring and proposing solutions for the many ways with which we perceive and interact with our spatial environment. A key aim of the work is to propose approaches for creating legible environments when urban space is experienced through mobile technologies such as GPS, WiFi, mobile phones and the internet.

Trolley interactive was set up in 1998 by Katharine S. Willis and work ranges from research to a range of projects in media and built space.

Trolley interactive is part of trolley, a collaborative container for projects that have a mind of their own.
