For the development of sustainable ICT services, participation of the local communities is crucial. A meaningful involvement requires awareness and understanding of the various possibilities of the ICTs. In this paper, the processes of awareness raising among underprivileged population in the Sri Lankan tea estate district of Nuwara Eliya are examined, drawing on the findings from an empirical study conducted at two telecentres. A specific participatory methodology, where co-inspirational sessions and brainstorming constituted main activities of co-creation of knowledge was applied. Our empirical data confirms that the participatory methods can trigger curiosity and engagement among participants. Ideas and suggestions that emerged during brainstorming demonstrate relevance, realism as well as they are a proof of real needs and requirements of a population that lives under difficult conditions in remote locations. Participatory methods can initiate community engagement for a longstanding, sustainable transformation of the TCs, in collaboration with ICT developers, and TC staff.
