User requirements for a collective intelligence emergency response system

This document reports on the HCI experience gained in WeKnowIt, a European project aiming to design, implement and deliver technologies and methodologies enabling both Emergency Response organisation personnel and community citizens to participate in the monitoring of an emergency incident. In order to better capture the richness and complexity of the scenario, user studies were conducted to elicit user requirements from both user groups to understand how their requirements can be met by an application that combines organisational and community intelligence.
