On-photo Restitution and Management of an Angular Size-Illusion\u27s Behaviour Experienced in Architectural/Urban Spaces

An angular size-illusion refers to a contradictory effect related to a seeming size-decrease of focused objects as the observer approaches them. This paper continues the research in this field, trying to establish fundamental principles of how to: (a) efficiently perform an on-photo restitution of an illusion\u27s behaviour (expressed by illusion descriptors) when it is experienced in architectural/urban spaces during movement under the influence of available triggers (represented by illusion determinants of physical nature), and (b) manage it computationally so as to be sustainable for contemporary professional practice. To explain that conceptually, one simple architectural/urban matrix is chosen and digitally photographed. Images are photogrammetrically processed and determinants-related data obtained. Subsequently, descriptors-related outputs are calculated by applying derived mathematical equations (expressed in function of those determinants-related data). Then, behaviour-charts are created and corresponding illusion-characteristics read-off. Finally, it is illustrated how to manage (intentionally modify) the restituted behaviour by varying values of acquired determinants-related data. Given results allow also to "design a new illusion" (to programme and control it) by simulating in digital VR/AR environments. Thus, any cause of unwanted/unpredictable visual impression degradations of important architectural/urban structures can be prevented or minimized (by planning and performing adequate spatial/physical interventions on existing/reconstructed/newly designed matrices)

FACILITY MANAGEMENT: A PARADIGM FOR EXPANDING THE SCOPE OF ARCHITECTURAL PRACTICE

In this paper the authors discuss challenging interrelations between the contemporary architectural practice and the expanding facility management (FM) sector. After defining FM and determining the part of it that is directly dependent on an architectural expertise, the authors identify possible interests in combining knowledge between the two fields, both dealing with the built environment. The empirical part of the research is a study of the current development of FM concepts and strategies in Serbia, and examination of the position and a possible impact of the local architectural practice. A systematization of local real-estate from the point of FM includes three different groups of objects: the ones with integrated FM strategy in the early design stage; the ones with imported FM strategy from international firms; and the last incomparably largest group of objects that desperately need an appropriate FM concept. The methodology of tracking the FM related knowledge has been applied with the aim to recognize key actors in the FM knowledge exchange on the national level, as well as to understand current position and propose possible activities for the local architectural community
