title	Artificial Intelligence in Engineering : Robotics and Processes
source	403 p. Amsterdam: Elsevier/CMP, 1988. CADLINE has abstract only
summary	This volume contains the papers in the robotics and processes areas from the Third International Conference on Artificial Intelligence in Engineering. Robotics has the potential to change the physical face of engineering and has no counterpart in traditional engineering. It requires the integration of numerous disparate aspects of engineering. There is a fundamental requirement for geometric and spatial reasoning of a qualitative kind. A variety of other processes in engineering are being examined through the artificial intelligence lens. The material collected under the process rubric demonstrates both the benefits and potential of utilizing this approach. The papers are presented under the following headings: Robotics; Geometric and Spatial Reasoning; Interpretation Processes; Reasoning Processes; Planning and Scheduling Processes; Interfaces

title	Situated Computing: A New Paradigm for Design Computing
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, p. 1
summary	Computer usage in design has largely been in the areas of document production, 3D modelling and to a lesser extent in specialised design analysis and design synthesis tasks. This use of computers by designers has been based on well-defined practices that have their genesis in the scientific approach to knowledge. Just as knowledge is independent of its use and independent of its user, so computer programs are designed to be independent of their use and independent of their users. This talk presents a complementary paradigm based on the notions of situated cognition as the basis of the development of new kinds of computational design tools.Situated cognition holds that where are you and when you are there matters and that the state you are in affects what you do. The fundamental difference is between encoding all knowledge prior to its use to allowing the knowledge to be grounded in the interaction between the computational system and its environment. In addition to the concepts of situated cognition there is another important concept called constructive memory. Constructive memory changes our view of “memory” in acomputational system from being a thing in a place that can be accessed with the correct index to being a process that produces a “memory” when needed. Thus, memory is constructed as needed and becomes a function of both the question it is used to respond to and the situation within which it was asked. These concepts provide the foundation for the developmentof novel tools to support computer-aided designing. Examples of situated cognition and constructive memory will be presented. This will be followed by examples of situated design analysis and situated computational design creativity.

title	Online Photorealistic VR with Interactive Architectural Objects
doi	https://doi.org/10.52842/conf.ecaade.1999.414
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 414-417
summary	This paper describes how Virtual Reality (VR) technologies can be used for modelling photorealistic environments with interactive and changeable architectural content. This application of VR allows us to create photograph-based panoramic models of real places that include a variety of interactive architectural objects and details. The user is able not only to navigate through a virtual environment (look around, up and down, zoom, jump to another viewpoint or location) but also to change buildings or their architectural details by clicking, moving or rotating. The following types of interactive objects are completely integrated with a virtual environment: 2D image-based objects, 3D image-based objects, 3D VRML-based objects and onscreen world controls. The application can be used effectively for teaching, including distance Internet-based education, project presentations and rapid prototyping. A sample VR environment is presented and some of the key creative and technological issues are discussed.

title	Sense of Place in Virtual Heritage Environment: A Review
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 181-189
summary	The use of computer technology is becoming a necessity to many organizations particularly as a means of representation and visualization. In the context of culture and heritage it is often developed in the form of virtual heritage. This is due to the fact that some of these intangible values are faded or even lost in museums they are placed, or buried in its physical remains and ruins. The concept of portraying the richness of sense of place via the use of virtual reality (VR) technology is seen to be of great potential to give value to the heritage sites. Thus, VR allows a unique representation of the intangible heritage elements while evoking the user’s senses, emotions, memories, meanings and interpretations, though these are arguably complex to accomplish. This paper reviews literatures on factors that influence the character of place and sense of place, and the use of VR technology and virtual world design to suggest presence for virtual heritage development.

source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 427-432
summary	Using Lynch’s (1960) treatise The Image of the City as a model, user navigation of e-retailing web sites was analyzed using defined categories: paths, districts, edges, nodes, and landmarks. Results from this study suggest that elements in the urban landscape and their use by individuals for way finding and legibility may be similar to those necessary for navigating the World Wide Web.

source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	This project had as goal to investigate how an urban space can be represented, and how can we to present information that facilitated broad and interactive spatial analysis in an easy and friendly way. This target was reached trough the elaboration of a computer application that allowed urban information visualization about Salvador City. This tool let users to build thematic cartography, visualize interactive 3D models, images, etc. Project development already produced two different prototypes. First versions provide a great spatial analyze flexibility, but it interface founded in a workspace defined do not allow user to do all overlayer possible. In this case the tool was a kind of cartographic atlas. The actual version had as design presuppose, to give users more information, interactivity, power and flexibility, adopting new medias, new representation models, and presenting quantitative and qualitative information.

summary	The highly developed glasfiber technology of the Berlin ISDN-B prototype network will make it possible to test a future benefit of the possibilities of real time visual communication for architects and planers in their home office. In the project an external user will be able to share high end visual outputs of a Service Center for Visualisation with his own low end CAAD workstation via ISDN-B. The capabilities of these services will range from a still picture archive, real time access to video film archive, a variety of conventional database services to special postproduction for his own 3D data models. The transferred 3D model can be rendered an animated on the Center's systems, if requested also integrated into a video background film. The production will than be available on his workstation screen. These new means will be evaluated in the view of the architects new possibilities for the design process.

title	Secret Whispers & Transmogrifications:a case study in online teaching of Augmented Reality technology for collaborative design production.
doi	https://doi.org/10.52842/conf.caadria.2021.2.021
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 2, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 21-30
summary	This paper focusses on teaching the integration of Augmented (AR) and Mixed Reality (MR), combined referred to as Extended-Reality (XR), and photogrammetry technology into handicraft using an online-taught digital fabrication workshop as an educational case study. Set up in response to restrictions from Covid-19, workshop 'Secret Whispers & Transmogrifications' had students and instructors around the world participate in a course that challenged our understanding of educating craft and technology without the necessity of physical presence. The integration of AR into craftsmanship enhances architectural design and fabrication processes as it overlays computation-driven information onto the hands of the end user. These computer-numerically-controlled workflows incorporate and rely on manual actions as an integral part of a process that is typified by inevitable, unpredictable, human error. In doing so, the workshop questions common infatuation with precision in digital fabrication and construction by striving for alternative approaches that embrace the inaccuracies and imprecisions innate to technologically-augmented human craftsmanship. Participants took part in a hands-on clay modelling 'secret whispers' experiment that was designed to introduce theoretical concepts and applications of XR technology into the production workflows. This paper concludes by highlighting that the accessibility of today's technology enables AR-enhanced craftsmanship to be successfully taught remotely and online.

title	Smalltalk-80: The language and its implementation
source	New York, NY: Addison Wesley Co
summary	Smalltalk-80 is the classic standard Smalltalk language as described in Smalltalk-80: The Language and Its Implementation by Goldberg and Robson. This book is commonly called "the Blue Book". Squeak implements the dialect of Smalltalk described in this book, but has a different implementation. Overview of the Smalltalk Language Smalltalk is a general purpose, high level programming language. It was the first original "pure" object oriented language, but not the first to use the object oriented concept, which is credited to Simula 67. The explosive growth of Object Oriented Programming (OOP) technologies began in the early 1980's, with Smalltalk's introduction. Behind it was the idea that the individual human user should be the most important component of any computing system, and that programming should be a natural extension of thinking, and also a dynamic and evolutionary process consistent with the model of human learning activity. In Smalltalk, these ideas are embodied in a framework for human-computer communication. In a sense, Smalltalk is yet another language like C and Pascal, and programs can be written in Smalltalk that have the look and feel of such conventional languages. The difference lies * in the amount of code that can be reduced, * less cryptic syntax, * and code that is easier to handle for application maintenance and enhancement. But Smalltalk's most powerful feature is easy code reuse. Smalltalk makes reuse of programs, routines, and subroutines (methods) far easier. Though procedural languages allow reuse too, it is harder to do, and much easier to cheat. It is no surprise that Smalltalk is relatively easy to learn, mainly due to its simple syntax and semantics, as well as few concepts. Objects, classes, messages, and methods form the basis of programming in Smalltalk. The general methodology to use Smalltalk The notion of human-computer interface also results in Smalltalk promoting the development of safer systems. Errors in Smalltalk may be viewed as objects telling users that confusion exists as to how to perform a desired function.

summary	Traditional narrative systems, such as literature, the cinema and the television, keep a linear design when developing a story, due to their own characteristics. Multimedia offers the possibility of developing a new narrative language. Multimedia fiction is based on the idea of working on a new medium, taking the previous ones as a starting point. In this new medium, the decisions taken by the user, will enable him to create his own version of the story. Work done in this field, have attempted to investigate and go deeper into these concepts.

summary	The paper is a comparison of interface changes as a result of modern concepts and a new hardware development. It explains the notion ‘virtual’ and its application in a few generations of user interface. Modern interfaces are chained with simulation technology. The meaning of simulation is strictly related to the notions: possible, actual, potential force. All of them are ingredients of ‘virtual’. Finally interfaces bring to the point: what virtual is?

title	Bernstein- Bezier Methods for the Computer-Aided Design of Free-Form Curves and Surfaces
source	Journal of the ACM. April, 1974. vol. 21: pp. 293-310 : ill. includes bibliography
summary	The mth degree Bernstein polynomial approximation to a function f defined over [0,1] is Em-o f(u/m) Ou(s), where the weights Ou(s) are binomial density functions. The Bernstein approximations inherit many of the global characteristics of f, like monotonicity and convexity, and they always are at least as 'smooth' as f, where 'smooth' refers to the number of undulations, the total variation, and the differentiability class of f. Historically, their relatively slow convergence in the Loo-norm has tended to discourage their use in practical applications. However, in a large class of problems the smoothness of an approximating function is of greater importance than closeness of fit. This is especially true in connection with problems of computer-aided geometric design of curves and surfaces where aesthetic criteria and the intrinsic properties of shape are major considerations. For this latter class of problems, P. Bezier of Renault has successfully exploited the properties of parametric Bernstein polynomials. The purpose of this paper is to analyze the Bezier techniques and to explore various extensions and generalizations. In a sequel, the authors consider the extension of the results contained herein to free-form curve and surface design using polynomial splines. These B-spline methods have several advantages over the techniques described in the present paper

title	Data Visualization Methods for the Blind using Force Feedback and Sonification
source	Stein, M. (Ed.). Telemanipulator and Telepresence Technologies V. Vol. 3524
summary	Research in the field of scientific visualization has begun to articulate systematic methods for mapping data to a perceivable form. Most work in this area has focused on the visual sense. For blind people in particular, systematic visualization methods which utilize other sense need further development. In this work we develop methods for adding aural feedback to an existing haptic force feedback interface to create a multimodal visualization system. We examine some fundamental components of a visualization system which include the following: characterization of the data, definition of user directives and interpretation aims, cataloging of sensual representations of information, and finally, matching the data and user interpretation aims with the appropriate sensual representations. We focus on the last two components as they relate to the aural and haptic sensor. Cataloging of sensual representations is drawn form current research in sonification and haptics. The matching procedure can be thought of as a type of encoding which should be the inverse of the decoding mechanism of our aural and haptic systems. Topics in human perception are discussed, and issues related to the interaction between the two sensor are addressed. We have implemented a visualization system in the from of a Windows NT application using a sound card and a 3 DOF point interaction haptic interface. The system present a 2D data set primarily as a polygonal haptic surface although other capabilities of the haptic sensor are utilized such as texture discernment. In addition, real time aural feedback is presented as the user explores the surface. Parameters of sound such as pitch and spectral content are used to convey information. Evaluation of the system's effectiveness as an assistive technology for the blind reveals that combining aural and haptic feedback improves visualization over using either of the two senses alone.

title	Issues and Experiences Designing and Implementing Two Group Drawing Tools
source	Readings in Groupware, 609-620
summary	Groupware designers are now developing multi-user equivalents of popular paint and draw applications. Their job is not an easy one. First, human factors issues peculiar to group interaction appear that, if ignored, seriously limit the usability of the group tool. Second, implementation is fraught with considerable hurdles. This paper describes the issues and experiences we have met and handled in the design of two systems supporting remote real time group interaction: GroupSketch, a multi-user sketchpad; and GroupDraw, an object-based multi-user draw package. On the human factors side, we summarize empirically-derived design principles that we believe are critical to building useful and usable collaborative drawing tools. On the implementation side, we describe our experiences with replicated versus centralized architectures, schemes for participant registration, multiple cursors, network requirements, and the structure of the drawing primitives.

title	CoDraw “Graphical Constraints in CoDraw”
source	IEEE Workshop on Visual Languages, Seattle, WA, pp. 81-87
summary	Constraint based draw programs require users to understand and manage relationships between drawing elements. By establishing constraint relationships among elements the user effectively programs the drawing's behavior. This programming task requires a more sophisticated visual interface than conventional draw programs provide. Users must have available - in a convenient format - information about the structure of the constraints that determine the drawing's interactive edit behavior. This format must support editing and debugging. CoDraw is a constraint based drawing program that can be interactively extended by its users. This paper describes the CoDraw program and its programming interface.
