title	Remote Computer Generated Physical Prototyping Based Design

summary	This research explores some of the opportunities offered by the field of computer aided design. It differs from much of the research in the field in the sense that it extends beyond the boundaries of the computer screen by building and testing a computational and communication design environment made of computers, computer peripherals and digital communication devices. From our observation of the designer's interaction with the computer generated physical prototyping systems we were able to confirm the unique haptic feedback and understanding of complex three- dimensional geometry. We also found limitations of the environment in relation to evolutionary design. It was clear from those experiments with algorithmically generated design alternatives that potentially terrific opportunities lies in their combination with computer generated physical prototypes and manufacturing systems.

title	Computer-generated physical modelling in the early stages of the design process
source	Automation in Construction 11 (3) (2002) pp. 303-311
summary	This paper illustrates some of the opportunities arising from the introduction of computer-generated physical modelling1 in the early stages of the architectural design process. The use of this technology in the design process differs from previous research and practise in that it looks at the use of computer-generated physical modelling recursively in design process rather than as a means to create a final presentation model [W.J. Mitchell, M. McCullough, Digital Design Media, Van Nostrand Reihnold, New York, 1994]. Previous research in the field by the author identified recursive strategy in the design process as the area in which computer-generated physical modelling offers unique opportunities to the designer. Three unique advantages in the use of computer-generated physical modelling technology are illustrated by three case studies. These advantages are: (1) understanding kinetic design, (2) understanding design involving complex geometry and (3) understanding design at the interface with the human body.

source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 445-454

summary	This paper presents a computational design methodology through describing of a case study on stone building system. In addition to establishing a performance driven form-finding methodology, the objective is to redefine local craftsmanship methods as industrial fabrication techniques in order to introduce the constructability of the design solutions as one of the main performance criteria. Therefore, the focus of the methodology is to facilitate architectural design processes through developing of customized computational design tools and workflows for data integration and concurrent performance evaluation. The research starts with the hypothesis that the technological advancements in digital design and fabrication can lead to re-exploration and improvement of traditional building techniques with local materials. The paper explains different stages of the methodology and the way the chained design to fabrication processes would lead to constructible, structurally possible and optimal design solutions of small scale and simple symmetric design solutions to complex topologies at the scale of larger complex buildings.

title	Thermocatalytic Metafolds
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 57-67
doi	https://doi.org/10.52842/conf.acadia.2015.057
summary	Thermocatalytic Metafolds comprises a paper-based fabrication process that initiates ascetic self-assembly via heat application. Metafolds utilizes a composite material of paper with a selectively applied shape-changing polymer crafted via a multi-step computational, two-dimensional drafting fabrication method. Upon heat application, the paper self-folds into predetermined, three-dimensional, highly accurate, rigid shapes. The final product maintains a notable resilience to alteration, and the stringency of form serves as a testament to the process’ potential to transform the ways in which design is undertaken. This exploration of material properties has cumulated in a process that demonstrates a design based on a detailed understanding of how the composite material behaves under specific conditions.

source	Computing in Design - Enabling, Capturing and Sharing Ideas [ACADIA Conference Proceedings / ISBN 1-880250-04-7] University of Washington (Seattle, Washington / USA) October 19-22, 1995, pp. 357-370

summary	Societal appreciation of architecture, the environment and the role of design & planning professionals should begin early in the educational stream. Working from this premise, a model was developed which relied on a combination of learning strategies: Cognitive, Psychomotor and Affective. The project’s primary goal was to build knowledge of architecture and the environment in K-12 children, with particular emphasis on primary levels. More specifically, the ARCH was selected thematically as a strong architectonic element through which to promote a better connection with and responsibility for the environment. The educational experience comprised three sequential forms: visual history of the ARCH, physical construction using foam blocks, and finally "construction” in the computer using a multi-media interactive three-dimensionally focused program. Pedagogically the sequencing provided explanation and context, built awareness through making, and finally reinforced the lessons of the previous steps while highlighting the potential of information technology. To deliver the curriculum an installation was built at a local museum, with primary grade children arriving on field trips. Architecture faculty and students designed the curriculum and installation, including the computer modules. Secondary school students were trained, with the intention that they would in turn educate primary school students at the installation. In disseminating knowledge downwards through the various educational levels, awareness was promoted concerning the architects role, architectural elements, and the broader built environment. Using the ARCH as the theme, realization of the inter-connectedness of the environment was advanced. Through linking and learning, participants came to better understand the value of their individual contributions and the critical need for collaboration.

summary	The research dealt with developing low-cost formwork techniques for funicular slabs by trying to achieve similar-sized triangular modules to help achieve a near-perfect funicular shape. Instead of applying meshing patterns on already developed funicular shapes, the approach taken in this research was to mesh the planar topology and then analyse the similarity of triangles achieved on the relaxed geometry. 3 types of meshing patterns were applied to 5 types of planar shapes for a span of around 4 to 7 meters and the similarity of the triangles was measured through standard deviation. The meshes were structurally analysed and results like deflection and bending stresses helped in assessing which meshing pattern performed better under gravity and imposed loads. Prototypes in different scales were created to suggest a low-cost buildable solution.

title	Face Recognizing Robot
source	International Conference on Generative Art
summary	In the biological evolution process, logical thinking has been the last to evolve, and lies at the surface of our consciousness, its means and methodologies available for introspection. On the other hand, the intelligence required to interpret sensory signals and activate motor commands is so well known biologically that it is buried in the subconscious and is entirely inaccessible at the conscious level. The variation in human intelligence is usually measured by the ability to process logical information, whereas the other forms of intelligence needed in daily life are not normallyassociated with the word intelligence. In the recent years man wants to develop a machine having its own intelligence. He wants to make machine, to which he can treat as a real servant. In this paper a simulated robotic system is described, which can be used as a criminal-detecting robot. In this project, an attempt will be made to design a Robot and it’s software, which will have an optimal solution of conditions (for which the Robot is to be designed i.e. security). It will not only reduce the cost (the cost spend insecurity of VIP’s is very high) but also will increase the security strength and stop the criminal activities. It will take snaps of the people and match from its database to check for criminals. Thus, such operations with minimum errors will cause the better security. Computer vision concerned with the sensing of vision data and its interpretation by a computer. Detecting faces in images with complex backgrounds is a difficult task. The approach presented in this paper, which obtains state of the art results, is based on a new neural network model. To detect a face in an image means to find its position in the image plane (x, y) and its size or scale (z). An image of a face can be considered as a set of features such as eyes, mouth, and nose with constrained positions and size within an oval: an explicit model can be used. The think and adjust himself in any condition, can take the optimal and possible decision. The Robot can perform only those tasks and take decisions, which are specified in its programming code.

title	The Cadastral Information System and its Objectives
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 213-218
summary	The solutions that allow us to attend the potential exigencies planned for a territorial administration, oblige us to establish an informatizated step, performed with a group of logical tools, supported in the corresponding data bases. This means to establish an Information System who integrates basic data to activities and own resources, being a fundamental aspect of these Systems their capacity to synthetisize the dinamic of phenomena that reflect and several parameters that are the base to analyse this. Urban and Rural real estates (cadastral register) are elementary territorial unities whose integration, complemented with structural elements of a localization area, constitute the continuous of spatial information with the most degree of resolution. Trying as "variables” all physical, economical and juridical circunstances, this continuous of information in transformed in an extraordinary and interesting product, which can be potentiate if we include the Geographic Information System (GIS) concept, resulting of adding digital cartographic data bases to attributes and literal characteristics of elements stored in alphanumeric ones. The reason of this article is to divulge the Territorial Information System set up in the Cadastral Office of the City Hall of Montevideo, based on GIS technology, emphatizying the utility it produces in so large applications as: to investigate land occupation and property distribution, to planify and optimize resources and services, to act as a fundamental support to elaborate thematic cartographies, to serve as a detailed and precise support for urbanism, service flows and territorial ordenation and all other products issued for the own implantation philosofy, constituted with an open structure where the mentioned Office isn’t the only user.

title	Digital Exploration of Unbuilt Architecture: A Non-Photorealistic Approach
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 235-245
doi	https://doi.org/10.52842/conf.acadia.2003.235
summary	This paper presents a new approach to the digital investigation of unbuilt architecture. A navigable world, emulating the architect’s graphic style, is built as a 3D non-photorealistic reconstruction of the unbuilt project. A cinematic journey through this world intermediates the exploration of the architect’s possible mental visualizations during the creative stages. The goals of the proposed approach are: to open new avenues for investigating the conception of architecture, to help architectural students visualize and experience important unbuilt projects that have shaped the practice of architecture, and to popularize lesser-known architects to the general public. The approach stems from the idea that architectural drawings are the artifacts reflecting most accurately the architect’s creative and thinking processes. Anchored in the concept of multi-dimensional space developed by the author, the proposed method uses the original drawing of the artist as the main artifact on which the reconstruction process is based. The present paper concentrates on those aspects related to extracting information from the architect’s drawing and embedding historic knowledge in the 3D reconstruction of the unbuilt project. It calls to attention the idea that technological progress creates tools that the Architect uses to operate with the fundamental concepts of place, space, and time.

source	ENVISIONING ARCHITECTURE: IMAGE, PERCEPTION AND COMMUNICATION OF HERITAGE [ISBN 978-83-7283-681-6],Lodz University of Technology, 23-26 September 2015, pp.125-131
summary	The presented research questions the place and role of sensitivity to direct solar radiation in architecture and urbanism past and present. Our main hypothesis is that the relation which societies entertain with solar radiation is a cultural fact which directly influences their symbolic, social and material production, in particular the way they design the architectural and urban environments which they inhabit. In proposing a cultural approach to architecture and urbanism in the sun over time, we aim to show how the built environment reflects and organizes at one and the same time our individual and social relation to solar radiation.

doi	https://doi.org/10.52842/conf.acadia.1990.205
summary	In an attempt to enhance the communication between architect and client, research was conducted in the use of computer modeling and video imaging techniques for the final architectural presentation process. By superimposing the painted building design from the CAD system onto a digitized image of the intended location, a composite image was achieved. These techniques have advantages in creating a realistic composite image of a proposed building design in its intended location within a short period of time. In order to provide more visual clues, a multiple view presentation format using a series of selected views (multiple views) was used. In addition, the research had further attempted to present the video- computer presentation in an animation sequence. The animation presentations were evaluated by comparing them with the multiple view presentations. Manual rendering and single viewpoint displays were also included in the comparisons in order to validate the results. Questionnaires were used to measure the capability of each presentation format to communicate the intended information to the audiences. The experiments were conducted with non-architecture subject groups in the local Bryan/College Station area.

title	Video-Computer Imaging Techniques: the Effect of Presentation by Animation and Multiple Views on Comnnunicative Effectiveness of an Architectural Design
source	Texas A&M University
summary	In an attempt to enhance the communication between architect and client, research was conducted in the use of computer modeling and video imaging techniques for the final architectural presentation process. By superimposing the painted building design from the computer-aided design (CAD) system onto a digitized image of the intended location, a composite image was achieved. These techniques have advantages in creating realistic composite images of proposed building designs in their intended location within a short period of time. In order to provide more visual clues, a multiple view presentation was examined. In addition, the research attempted to present the video-computer in an animation sequence. This was done by creating a series of sequential composite images, and recording them frame by frame onto the video tape. Then, the animation presentation was played back in real time. The animation presentations were evaluated by comparing them with the multiple view presentations. Manual rendering and single viewpoint displays were also included in the comparisons in order to aid in interpretation of the results. Questionnaires were used to measure the capability of each presentation format in communicating the building design information to non-architecturally trained persons. The results indicate that video-computer presentations were equal to or better than manual rendering. The video-computer presentations, with their short production time, were more practical to use in the architectural process than the conventional presentations. The results of the comparisons revealed that video-computer presentations in animation format were superior to those of multiple view format in the depth cue category. On the other hand, video-computer presentations by multiple view format was found to be superior to animation format in communicating both size and scale. These results occurred under the different complexity levels of the buildings used.

title	New Communication Processes The Impacts of the Economy on Urban Issues in Slovenia areas
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The time in which we live today is marked by quick economic, political, and social changes. We can also add the new development potential of European space, which is not formed only within the borders of EU; their influences are also reaching into neighboring countries and beyond their borders into wider areas. If we summarize the main characteristics of settlement development over the past decade in Slovenia, it is necessary to stress out that those processes were marked by developmental dynamics, which profoundly changed traditional images of the cities and settlements.The most explicit characteristics of the current developmental trends is the strengthening of the centers of economic power - dense city areas, which compete with competitive advantages of their location, with an emphasis on traffic and other infrastructure equipment.

title	Sketching input for computer aided engineering
source	City University, Department of Mechanical Engineering and Aeronautics
summary	The design process often begins with a graphical description of the proposed device or system and sketching is the physical expression of the design engineer's thinking process. Computer Aided Design is a technique in which man and machine are blended into a problem solving team, intimately coupling the best characteristics of each. Solid modelling is developed to act as the common medium between man and the computer. At present it is achieved mainly by designing with volumes and hence does not leave much room for sketching input, the traditional physical expression of the thinking process of the design engineer. This thesis describes a method of accepting isometric free hand sketching as the input to a solid model. The design engineer is allowed to make a sketch on top of a digitizer indicating (i) visible lines; (ii) hidden lines; (iii) construction lines; (iv) centre lines; (v) erased lines; and (vi) redundant lines as the input. The computer then processes this sketch by identifying the line segments, fitting the best possible lines, removing the erased lines, ignoring the redundant lines and finally merging the hidden lines and visible lines to form the lines in the solid in an interactive manner. The program then uses these lines and the information about the three dimensional origin of the object and produces three dimensional information such as the faces, loops, holes, rings, edges and vertices which are sufficient to build a solid model. This is achieved in the following manner. The points in the sketch are first written into a file. The computer than reads this file, breaks the group of points into sub-groups belonging to individual line segments, fits the best lines and identify the vertices in two dimensions. These improved lines in two dimensions are then merged to form the lines and vertices in the solid. These lines are then used together with the three dimensional origin (or any other point) to produce the wireframe model in three dimensions. The loops in the wireframe models are then identified and surface equations are fitted to these loops. Finally all the necessary inputs to build a B-rep solid model are produced.

doi	https://doi.org/10.52842/conf.acadia.2017.552
summary	The expanding role of computational models in the process of design is producing exponential growth in parameter spaces. As designers, we must create and implement new methods for searching these parameter spaces, considering not only quantitative optimization metrics but also qualitative features. This paper proposes a methodology that leverages the pattern modeling properties of artificial neural networks to capture designers' inexplicit selection criteria and create user-selection-based fitness functions for a genetic solver. Through emulation of learned selection patterns, fitness functions based on trained networks provide a method for qualitative evaluation of designs in the context of a given population. The application of genetic solvers for the generation of new populations based on the trained network selections creates emergent high-density clusters in the parameter space, allowing for the identification of solutions that satisfy the designer’s inexplicit criteria. The results of an initial user study show that even with small numbers of training objects, a search tool with this configuration can begin to emulate the design criteria of the user who trained it.

title	Non-Visual Haptic Interaction Design - Guidelines and Applications
source	Lund Institute of Technology, School of Architecture
summary	This dissertation has three cornerstones:* Haptics * Human-Computer Interaction (HCI) * Blind Users Haptics deals with controlling human movements and getting feedback through the sense of touch. A haptic interface transmits forces to a person’s hand or fingers in a way that mimics the sensation of touching real objects. Virtual haptic touch can be particularly useful for people with visual impairments. It makes it possible for a blind person to touch virtual objects, corresponding to the way a sighted person can see objects on a computer screen. The goal of this research was to carry out an unbiased investigation of the potential of this technology for blind people. The more specific aims were to:* Investigate if and how blind people’s computer usage can be improved by virtual haptics. * Investigate the problems that arise with graphical user interfaces for blind people and how these problems can be managed with haptics. * Develop new applications and find new areas in which virtual haptics can be applied for blind people. The design process has been primarily influenced by theories of usability engineering and reflection in action/reflection on action, focusing on the role of the engineer-designer. A concerted effort is made to use technology as a language to communicate with the users.Several haptic interface devices have been involved. The Phantom from SensAble Technologies has been used the most. It is a small robot with a thimble or stylus attached to the tip which supplies force feedback to the user. The others are the FEELit Mouse from Immersion and the force feedback joysticks from Logitech and Microsoft.Eighteen test applications were developed over five years’ time. They included games, curves, textures, drawings, menus, floor plans, and geometrical objects. Formal and informal user tests were performed on blind, blind-deaf and sighted people.One of the key results presented are five guidelines for non-visual haptic interaction design for researchers, designers, testers, developers and users of such applications. The guidelines are:1. Elaborate a virtual object design of its own 2. Facilitate navigation and overview 3. Provide contextual information 4. Utilize all available modalities 5. Support the user in learning the interaction method and the specific environments and programs These guidelines represent the filtered and condensed knowledge and experience that the Haptics Group at Certec has gained during the testing and development process. They are further delineated and are a complement to existing HCI guidelines. This work shows that there is great potential in using haptic technology in applications for blind people. It is viable to translate both 2D and 3D graphical information and make it comprehensible via haptics. It has been demonstrated that a blind person can orientate and navigate in a virtual haptic environment and that these tasks can be further supported by using complementary information such as sound and Braille. It is also possible for a blind person to use knowledge gained in the virtual world for real life orientation.

summary	In spatial timber assemblies, a multitude of factors can lead to errors that hinder the implementation of complete automation including but not limited to inaccuracies of the robotic setup, deformations of the structures during assembly, or the natural dimensional variability of wood. Any unplanned event, construction detail, or material variability that was not embedded ahead of time in the CAD environment can cause failure. To mitigate these challenges, this paper expands this conventional one-directional design-to-fabrication pipeline and proposes interactive digital fabrication workflows where humans and robots work synergistically, blending the adaptability of human craft with the precision of robotic technology. The method is validated with two prototypes comprising linear timber elements and 3d printed connections that showcase adaptability in the fabrication setup and allow for design changes to happen concurrently with fabrication. In this paradigm, human operators are not mere extensions of the robotic system but rather central to dynamic problem-solving and instrumental in making immediate adjustments.
