This master’s thesis is framed in the areas of New Media Art (NMA) and Human Computer Interaction (HCI). In particular, it is focused in the study of New Media Art pieces that share a set of characteristics (the most important one being that they are composed by atomic elements), might be explicitly interactive, and are usually exhibited in public settings or have been designed to be consumed by a large simultaneous audience. The content of the thesis can be divided in four big items: 1- The review of a certain set of NMA pieces, their characteristics, and some similarities hold between them and the impressionist movement that emerged at the second half of the 19th century, along with some visual perception principles of Gestalt psychology. 2- A selection and an adaptation of pre-existing theoretical frameworks for modelling interaction in public settings. These theoretical frameworks comprise a set of tools for describing, analysing, and designing New Media Art pieces. 3- The presentation of a set of selected artworks authored or coauthored by the author of this thesis. A description of their characteristics and technology will be presented. 4- The introduction of two tools for artistic production, which were instrumental for the construction of some of the artworks here presented: Sendero (an LED lighting system), and N.IMP (a tool for real time visual content generation)
