Eugenio Tisselli discusses his project ojoVoz, an open source online-offline platform for the collaborative creation of community memories. Since 2011, he has worked with both urban and rural communities interested in presenting and re-presenting their common issues, and making them known to other members of their communities and the general public.

The ojoVoz platform allows groups of people to share their views and document their environment through geographically located pictures and sound recordings. These contents can be posted to a collaborative website, where they can be browsed using different criteria such as date, location or keyword.
