Following the successful Citizen Cyberscience Summit in 2010 (see http://www.citizencyberscience.net/summit/ ), we are organising a second meeting on the 16-18 February 2012. By citizen cyberscience, we usually refer to Internet-based applications that support volunteer computing and volunteer thinking. However, this time, as the summit will also mark the launch of the Extreme Citizen Science research group at UCL, we are extending the scope to cover all citizen science activities.

The summit will be structured as a 3-day event that will allow scientists, enthusiasts and citizen scientists to meet and discuss the various aspects of citizen science and citizen cyberscience, and even develop prototypes for new projects.

The first day (Thursday 16th February 2012), the focus of the summit will be an academic seminar covering a range of citizen science activities, and exploring the process of engagement and participation, outreach of citizen science to the developing world, and the undertaking of challenging citizen science projects (e.g. in a rain forest or the Arctic).

The second day (Friday 17th February 2012) will include presentations on the technical aspects of citizen science, such as the need for suitable hardware and software; a panel discussion with citizen scientists about their perceptions, participation and engagement; and a showcase of citizen science projects. In addition, we will launch a ‘hackfest’, which will carry on to the next day and is aimed at developing demonstrations of hardware and software that can be used in citizen science projects.

The final day (Saturday 18th February 2012) will include further unconference sessions, workshops and development of prototypes, with an afternoon talk, presentations and awards for the best prototypes.

Overall, we hope to cover a range of topics of relevance to citizen science research and practice, including technical aspects of citizen science such as use of sensors; applications of smartphones for data collection or in combination with external sensors; linking the Internet of Things (IoT) and Citizen Science – sensor networks to human sensors; motivations, incentives and engagement patterns;Citizen Science with indigenous and low-literacy communities; social science, ethnographic and anthropological aspects of Citizen Science and similar topics.

During the second and final days, there will be an opportunity to present short papers, run panels, organise workshops or provide showcase demonstrations. We would like to invite anyone interested in participating in this way to submit brief proposals using the form
