The NECA Project (Net Environment for Embodied Emotional Conversational Agents) was a research project that focused on multimodal communication with animated agents in a virtual world. NECA was funded by the European Commission from 1998–2002 and the research results were published up to 2005.〔Brigitte Krenn, et al. ''Lifelike Agents for the Internet'' in "Agent culture: human-agent interaction in a multicultural world" edited by Sabine Payr, Robert Trappl 2004 ISBN 0-8058-4808-8 pages 197-228〕〔(NECA Project description )〕〔Brigitte Krenn and Barbara Neumayr ''Incorporating animated conversation into a web-based Community Building Tool'' in "Intelligent virtual agents: 4th International Workshop, IVA 2003", edited by Thomas Rist ISBN 3-540-20003-7 pages 18-22〕 The project focused on communication between animated agents in a virtual world, using characters that exhibit realistic personality traits and natural looking behavior that reflects the emotional features of conversations. The project goal was to combine different research efforts such as situation-based natural language and speech generation, representation of non-verbal expression, and the modeling of emotions and personality.〔〔''Multimodal Intelligent Information Presentation'' by Oliviero Stock 2005 ISBN 1-4020-3049-5 page 64〕〔Patrick Gebhard, et al. ''Coloring Multi-character Conversations through the Expression of Emotions'' in "Affective dialogue systems" edited by Elisabeth André 2004 ISBN pages 125-139〕 ==Goals and milestones== The underlying research direction of the NECA Project was the development of a computing platform in which animated characters within a virtual world could be capable of realistic behavior. For character interactions to look natural, various factors such the proxemics of the distance between their bodies as they interact, to the kinesics of body language at the individual level, and the level of eye contact between individuals, as well as the paralinguistics of tone and intonation of sentences had to be considered. Based on that the there were three main goals for NECA.〔 The first goal was the general development of a platform that allowed the simulation and interaction of conversational characters. The second goal was the design of a multi-user web-application called the ''Socialite'', that allowed social "face to face" emotion-based interactions between animated agents on the internet.〔〔 The Socialite user could select a set of avatars to interact with and after learning about the user's personal preferences, the avatars helped the user navigate a virtual world and get in touch with other agents and users.〔 The third component was ''eShowRoom'' as an e-commerce platform demonstration that allowed for the display of products in the commercial domain. In the eShowRoom application, two or three virtual agents could be seen discussing various features of a product among themselves in a natural setting.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「NECA Project」の詳細全文を読む スポンサード リンク
