LEISURATOR tm …a new approach at the sports field. …a performative and adaptive vision of architecture in the realm of sports. …a transforming, responsive field for contemporary sports and games_ unformalized, innovative, hybrid, to engender improvisation. LEISURATOR tm is a design research project that provides a spatial response to the urban sensibility of the skateboarder, the morphing structure of today's games and challenge sports, the changing needs of recreation of the fast-living city dweller. LEISURATOR tm - performative and adaptive leisure generator field - provides a reconfigurable field that engenders a variety of leisure, sport and improvisational activities. This field is programmed with a set of variable configurations, the transformations of which offer emergent conditions suggestive of alternate social organization and cultural dimensions of game-like activities. Borrowing the urban sensibility of skateboarding culture, the design of the structure is informed by the series of temporal sessions, which by repetition over time will provide specific localization. The field structure will respond in two ways to the users. First, the kinetic mechanism will adapt to the existing programs considered as a timeline with environmental parameters. This pre-defines numerous configurations which are inscribed as latent performativities of the surface. Secondly, the adjacencies and relationship in each of these configurations is to catalyze new way of using surfaces, walls and edges of the field, providing both defined boundaries for existing leisure activities (e.g., tennis, jogging, playground), surfaces for non-formalized games (e.g., skating, casual play, etc.), and zones which allow the occupation of space in a game-like manner. It is a trademark for sports architecture considered as an extension to the equipment of the sports and moreover to the body of the superhuman. The project is presented officially to public at open jury on 30 January 2003 at the Architectural Association, within the Responsive Environments Agenda of the Design Research Laboratory.
