summary	A ‘curious place’ is an intelligent environment that is motivated to behave in a curious manner about activities that happen within the space. Recent research into self-motivated agents supports the development of physical places that can respond with curiosity towards novel events. This paper presents learning models suitable for developing curious places using agents and agent societies. These models are discussed with reference to a ‘curious research space’ we are developing as an example of a curious place.

source	Communications of the ACM April, 1983. vol. 26: pp.284-294 : tables. includes bibliography.
summary	Magnitudes and correlates of stress were investigated among 248 office workplace VDT users and 85 nonuser counterpart using field survey and objective physical measurement technique. Other than a tenuous indication of increased eyestrain and reduced psychological disturbances among users, the two groups were largely undifferentiated on job- attitudinal, affective, and somatic manifestations of stress. However, aspects of working conditions were judged less favorable by VDT users. Stress mechanisms were much the same for both groups, involving psychosocial as well as physical environmental job attributes
keywords	For VDT users, the chair and workstation configuration were particularly important predictors of musculo-skeletal disturbances, as were corrective eyewear use and ambient lighting for visuo-ocular

title	Data reduction of polygonal curves using B-splines
source	Computer-Aided Design, Vol. 31 (8) (1999) pp. 507-515
summary	We present a new method for data reduction of polygonal curves. Representation by means of a list of points does not provide fair curve models that may have complex andvarying shapes. We suggest a different technique based on fitting B-spline curves. This algorithm reaches high data reduction rates while producing fair approximations evenfor the most complex curves. We apply our technique to cartographic data but the method is suitable for any application where the number of data points must be greatlyreduced.

title	The interaction of time and cost constraints on the design process
source	Design Studies, 19[2]: 217-233, Apr
summary	This paper reports an experimental study investigating the influence of both `external' and `task inherent' constraints on simple design tasks. Subjects were required to complete each of 3 tasks in one of 4 conditions. The conditions comprised a control condition (no time or cost constraints imposed), a time constrained condition, a cost constrained condition and a time and cost constrained condition. The tasks required subjects to build structures predominantly from sheets of A4. For example, task one required subjects to `create a self supporting structure, which has a minimum height of 19 cm.' The pattern of results showed that the constraints of time and cost affected the design process both independently and in combination. In addition, the range of designs, completion times, and design costs were all affected differentially.

title	Collaborative Cooling Load Analysis Software for Public Participation on Energy Conservation
doi	https://doi.org/10.52842/conf.caadria.2007.x.o0s
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	This article is part of a research on developing cooling load analysis software for energy conservation. This research focuses on developing the system of Collaborative Design and Public Participation System which allows property owners, architects, engineers as well as others outside the field, to contribute to design process based on the concept of energy conservation within the collaborative virtual environment. The combination of the two ideas between collaborative virtual environment and Analysis Engine of cooling load calculation changes the traditional working processes in which architects and engineers work separately. From the traditional process where both architects and engineer redevelop the whole project from the beginning when redesigning is in need, this new collaborative process requires less time and energy from both parties due to the simultaneous participation of architects, engineers as well as other contributors. In this research, Microsoft© Direct3D® - API based Virtools® is used to develop Real-Time Simulation and its internal script in the calculation process. Through the implementation process, the study aims to develop the 3 components of 1) urban area database illustrating simulating maps for users 2) Graphic User Interface (GUI) connected to other software modules for further expansion and 3) Virtual Network Environment allowing multiple users to log in and use the programme at the same period of time.

title	Ray Tracing – New Chances, Possibilities and Limitations in AutoCAD
source	CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 121-136
summary	Realistic image synthesis is nowadays widely used in engineering applications. Some of these applications, such as architectural, interior, lighting and industrial design demand accurate visualization of non-existent scenes as they would look to us, when built in reality. This can only be archived by using physically based models of light interaction with surfaces, and simulating propagation of light through an environment. Ray tracing is one of the most powerful techniques used in computer graphics, which can produce such very realistic images. Ray tracing algorithm follows the paths of light rays backwards from observer into the scene. It is very time consuming process and as such one could not be developed until proper computers appeared, In recent years the technological improvements in computer industry brought more powerful machines with bigger storage capacities and better graphic devices. Owing to increasing these hardware capabilities successful implementation of ray tracing in different CAD software became possible also on PC machines. Ray tracing in AutoCAD r.12 - the most popular CAD package in the world - is the best of that example. AccuRender and AutoVision are an AutoCAD Development System (ADS) applications that use ray tracing to create photorealistic images from 3D AutoCAD models. These ,internal"' applications let users generate synthetic images of threedimensional models and scenes entirely within AutoCAD space and show effects directly on main AutoCAD screen. Ray tracing algorithm accurately calculates and displays shadows, transparency, diffusion, reflection, and refraction from surface qualities of user-defined materials. The accurate modelling of light lets produce sophisticated effects and high-quality images, which these ray tracers always generates at 24-bit pixel depth,"providing 16,7 million colours. That results can be quite impressive for some architects and are almost acceptable for others but that coloured virtual world, which is presented by ray tracing in AutoCAD space in such convincing way, is still not exactly the same as the real world. Main limitations of realism are due to the nature of ray tracing method Classical ray tracing technique takes into account the effects of light reflection from neighbouring surfaces but, leaves out of account the ambient and global illumination arising out of complex interreflections in an environment. So models generated by ray tracing belong to an "ideal" world where real materials and environment can't find their right place. We complain about that fact and say that ray tracing shows us "too specular world", but (...) (...) there is anything better on the horizon? It should be concluded, that typical abilities of today's graphics software and hardware are far from exploited. As was observed in literature there have been various works carried along with the explicit intention of overcoming all these ray tracing limitations, These researches seem to be very promising and let us hope that their results will be seen in CAD applications soon. As it happens with modelling, perhaps the answer will come from a variety of techniques that can be combined together with ray tracing depending on the case we are dealing with. Therefore from the point of view of an architects that try to keep alive some interest on the nature of materials and their interaction with form, "ray tracing" seems to be right path of research and development that we can still a long way follow, From the point of view of the school, a critical assimilation of "ray tracing" processes is required and one that might help to determinate exactly their distortions and to indicate the correct way of its development and right place in CAAD education. I trust that ray tracing will become standard not only in AutoCAD but in all architectural space modelling CAD applications and will be established as a powerful and real tool for experimental researches in architectural design process. Will be the technological progress so significant in the nearest future as it is anticipated?

title	O sistema “Kaléidoscope” de organização de referências ao projeto arquitetural [The system "Kaléidoscope" for reference organization in architectural design]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 129-132
summary	Our research focuses on how to create new types of computer tools, which aims to help early architectural design phase. Therefore we constructed a prototype named “kaleidoscope “. This system is based on the notion that architects use some external references as a strategy to construct new project ideas and that it is possible to organize this referential knowledge.This article presents four guide-lines which allowed the development of the first version of “kaleidoscope” system. As we succeed in broadening and deepening our knowledge - theoretical and empirical – about computers, wediscover that in large part their behavior is governed by simple general laws, that what appeared as complexity in the computer program was to a considerable extent complexity of the environment to which the program was seeking to adapt its behavior.

summary	Packaging design usually focus on the sale of the product, and leave other functions aside, such as the communication of information to the consumer. This article discusses how the changes in the visual language of the grid indicates that non-linear graphical features, such as data visualization, can improve the presentation of information in packages. A brief retrospective of the grid use in graphic design was made, wich were then related to examples of labels in the wine segment. The spatial dimension of data visualization proved to be relevant to information design in packaging.

title	Bric(k)Colage, CMU Spolia Composites: 3D scanning and printed clay for the recapture of CFD masonry waste
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 159–167
summary	This research investigates the use of LIDAR scanning, physics computational simulations, and ceramic 3D printing to streamline a process for generating a structural masonry bond-work from a given set of discarded pre-fabrication concrete parts. The research capitalizes on an initial set of large scale mockups developed using intuition based stacking of CMU Block detritus, which were in turn LIDAR scanned to produce a series of custom robotically 3d printed ceramic figural bricks to infill the gaps in a mortar based assembly. Following the proof of concept, the researchers explored computational means for simulating various configurations of aggregates using individually scanned broken blocks placed within a physics simulation. The outer boundaries are rigidly defined along with placeholders for desired apertures, and then the scanned detritus is dropped to inform a tight packed bond-work. The final digital aggregate is then run through a grasshopper simulation to derive the linework and print files for a robot to print the negative infill. This paper will discuss the ability for the designer to work within a computational process to produce structural envelope based construction with spoliated detritus towards new varied organizations embraces an aesthetic of visual reuse.

title	Retrieval of Similar Layouts in FABEL using AspecT
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 617-626
summary	In the FABEL project several approaches have been developed and published for retrieving similar cases in the domain of architectural design. In this paper we want to focus on a short description and foremost on integration of these approaches. We will introduce the most important approaches. As a first step towards integration, we suggest decomposing them into their main parts: representation of cases, similarity function and retrieval component. Using the first two parts each approach in a new search algorithm operating on a generic data structure, we built a shell called AspecT for an easy integration. We are positive that one can never have fully considered all aspects of a design. Therefore, we describe an open framework to define new aspects and to apply them depending on the context. Unfortunately, openness brings some difficulties along with it. One can not predict the importance of an aspect, until the situation assessment of the query is completed. In other words, it is impossible to define a static distribution of aspect weights that fits for all purposes. As a consequence, one can not predefine a static structure on the case base to speed tip retrieval processes. Dealing with this problem, we developed and published a special search algorithm that passes through a multidimensional case base, finding the best fitting cases within a short amount of time. This algorithm does not need any predefined structure on the case base except aspect specific relations between cases. Creativity of inventing new aspects of cases should not be hindered but one can ask whether or not a certain aspect are worth being regarded in searching for useful cases. The shell AspecT offers a tool to evaluate aspects. At first, formal criteria influence the initial weights of aspects but later on, the contribution of an aspect to find user accepted cases, determines the survival fitness of an aspect. The rule for living or dying is simple. Seldom used aspects disappear, whereas others become stronger. A short description regarding this work is given in last part.

title	Using Social Interaction in Generative Design of Shared Virtual Spaces
source	International Conference on Generative Art
summary	The proposed paper outlines research findings in the field of generative design of visual virtual chat spaces. It discusses social interaction as a central determining factor in the generation of virtual spaces through and for chat communication on the World Wide Web. Social interaction in a chat room is based on communication using written text. The research and design results of this project involve the translation of chat statements into three-dimensional virtual objects according to - criteria derived from theories of virtual and social space, - the production of space through action and interaction of the users of the interface and - the translation of the components of written text (words and characters) into three-dimensional virtual forms. The generation of a dynamic, virtual, social structure is based on criteria deduced from systems of interaction within social space. The visual social structure, reflected in the shape and spatial relation of the three-dimensional objects, evolves as source for feedback processes and therefore as “re-generation” of social interaction. This paper documents the design, implementation and evaluation of the described system. It represents an outset and a first manifestation of a new project in cultural-differentiated user-interaction-centred generative approaches in interface design of chat room applications.

summary	Simulating the impact that built environments produce on human behavior prior to a building’s construction and occupancy is a complex task in architectural design. Current simulation approaches provide a limited representation of how dynamic spatial, social and environmental conditions affect the behavior of autonomous virtual occupants. We address this issue by means of influence maps – spatial representations of the influence that dynamic stimuli exert on an occupant at a specific time. To support an agent’s decisionmaking, we construct affordance maps that determine possible space-occupant interactions based on the combination of normalized influence maps, weighed by occupant preferences. We demonstrate the proposed approach by simulating the diverse spatial behaviors of virtual occupants in a social setting in response to dynamic stimuli.

title	Changes of access in local and global facilities due to the development of transport information systems TIS
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The advent of communications technology has revolutionised the way that we conduct our affairs. Services are now more prolific andaccessible. Traffic Information Systems are helping to deliver those services. It is important to recognise which services are sought after by the public and how they can be improved by TIS (Traffic InformationSystems). Freight transport is one service that will increase due to the perceived chance in global access (Internet orders) and that canbe improved by TIS. If goods are to be regularly ordered from afar then they need to be cheaper and be delivered quickly. TIS systems through VMS signs, real-time traffic prognosis and public transport information are allowing us to conserve time as part of our daily lifestyles so that we can access our local facilities as readily as the improved freight networks allow us to access our global facilities. The correct implementation of TIS will make transport easier, and reduce congestion times, however it will only be able to do so, if it is possible to break the correlation of increase in GNP and traffic. Otherwise TIS services will still be useful but greatlymuted so.

summary	The main objective of this article is to grasp how technologies, techniques, and concepts related to Digital Fabrication were applied by South American players, in academic production from 2000 to 2021, through pedagogical activities, design projects, manufacturing processes, prototypes, and artifacts. We conducted a systematic review of publications from SIGraDi and eCAADe conferences, by authors active in South America during the period, identified from the CumInCAD database using the following terms: digital fabrication, digital manufacturing, digital fabrication, digital fabrication, rapid prototyping, CAD/CAM, robot* and 3d print*. 260 articles met the final criteria for inclusion, organized from the combination of 10 categories. The results show the dissemination of information about digital fabrication in many countries, focused on different trends of research and innovation, allowing us to understand the evolution of technological appropriation, thus offering an in-depth overview of our situation over the past 20 years.

summary	Laboratories based on the "Fab Lab" model have spread virtuously around the world in the past two decades. Over the years, some alternatives have emerged, establishing themselves in a more contextualized way. The article presents “other creative spaces”, involving case studies from three laboratories in South America: “Fábrica Diseno e Innovacion” (Argentina), “Fab Lab Livre SP” (Brazil), and “Exploratorio: taller público de experimentacion” (Colombia). In this way, it shows an analysis of the functioning of these laboratories in each condition, the practices emerging from these places related to the sociotechnical adequacy of digital fabrication technologies into their realities.

title	Applied Generative Procedures in Furniture Design
source	International Conference on Generative Art
summary	This paper discusses an approach which combines different generative procedures with design methods as they are common in daily design practice: Two generative tools together with paper models, prototypes and „classical“ Computer Aided Design span the design process. The subject of experimentation is a specific class of furniture: CNC - manufactured, foldable objects for different seating positions, based on a material composition of thin plywood laminated with fabric and / or felt. The generative tools described below have been developed with the macro programming facilities of the CAD-software I-DEAS. One tool can be used either for systematic exploration of the search space or as a source for inspiration, depending on the preference settings chosen by the user. The other tool is made for the elaboration of details of the generated designs and for preparing production. The prototypes of these tools are still in an experimental stage and just in use to be tested and evaluated. Therefore the charcacter of the following text is more descriptive than analysing.

title	Structural Analysis as Driver in Surface-Based Design Approaches
source	International Journal of Architectural Computing vol. 6 - no. 1, pp. 19-39
summary	This research argues for novel strategies to integrate structural analysis data in architectural design. Instead of a linear procedure of analysis, synthesis, evaluation and post-rationalization a synthesis/evaluation loop is installed which embeds structural analysis data as design driver from early on. The approach regards structural performance as one design criteria within a network of different requirements. An equilibrium of multiple parameters is aspired to instead of a single-parameter-optimum. The research is conducted via a custom-made digital interface between 3d modelling software and an application for structural analysis of space frames. The information exchange provides the basis for successive strategies within a collaborative design process of spatial roof structures: negotiation of an overall form and a multi-dimensional improvement of space frame topologies by a Genetic Algorithm (GA).

summary	A previously reported method for finding the points of intersection of a vector and a parametric surface patch is examined. However, before the point of intersection of a vector and a patch can be determined, it is necessary to find the patch (or patches) on a multipatch surface intersected by the vector. A technique is described for determining the patch or patches intersected by a vector, given the patches intersected by a single plane containing the intersecting vector. Once these have been found, the point of intersection can be determined and the distance to the multipatch surface obtained

summary	This paper describes the latest results of an ongoing research project that aims at using the power of self-organization for the design and optimisation of irregular spatial structures in real-world applications. An example is presented, which uses a growing swarm to define the configuration of randomly positioned columns in a large concrete structure. This agent based simulation, developed in cooperation with the building's architects and engineers, was successfully used in the final design stage of a project in the Netherlands to resolve the conflicting structural and functional requirements arising from the initial design.

source	Teaching and Research Experience with CAAD [4th eCAADe Conference Proceedings] Rome (Italy) 11-13 September 1986, pp. 295-304
summary	The Areal Data Management Package was created to fulfill the need for a data manipulation system on the basis of a grid cell data structure. The package was originally developed for use by research operators in land planning and natural resources. Over the past three years the package has been used extensively by various users, including students under and postgraduates. The ADM has been designed for users having no experience with computers, but it does assume understanding of resources and land planning information. The specific manipulative capabilities of ADM Package are designed to help land use planners analyze the natural and man-made characteristics of an area. The ADM is intended as a tool to manage spatially disposed thematic and categorical information, in many cases supplementing or analysis.
