EEG AR: Things We Have Lost allows participants to conjure up virtual objects by simply imagining them into existence using brainwave sensor technology. A database of objects based on the broad theme of “Things We Have Lost,” which includes things such as pensions, empires and dodo birds, has been generated by asking the people of Coimbra what they have lost.


The project consists of a city-wide public art installation viewable on smartphones and other mobile devices.

In the first iteration of this project in 2012 at FACT in Liverpool, people were selected at random in the streets of Liverpool and simply asked, “What have you lost?” The location was recorded and a series of virtual lost objects were created based on the responses given. The objects were then placed back in the exact GPS coordinates where the encounter took place, creating a citywide network of lost things, viewable on any mobile device.

This methodology will be repeated in the streets of Coimbra in May of 2014.
