title	VR Sketchpad. Create Instant 3D Worlds by Sketching on a Transparent Window
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 161-172
summary	This paper describes VR Sketchpad, a pen-based computing environment for inputting and locating 3D objects in a virtual world. Designer can use the transparency layers to quickly trace and extract any image underlay from other application software. The 3D scene generation has three levels of complexity: simple extrusion of any drawn lines of shapes (i.e., straight or curved wall and column extrusion), solid modelling from a given geometric object representation (spheres, cones and boxes), and complex configuration with objects from graphics library (furniture layout).

title	Analysing the significance of problem solving expertise and computational tool proficiency in design ideation
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 273-287
summary	This paper presents a pilot study to analyze the role of problem solving expertise (PSE) and computational tool proficiency (CTP) of expert and novice architects in the ideation process within a distributed cognition environment. To analyze PSE, we studied the frequency of occurrence of unique problem solving tasks per limited commitment mode (LCM) revisit. We also devised a quantitative measure for analyzing CTP based on the frequency of unique and normally distributed modeling activities per design process flows for a parametric modeling tool. In our study that involved freehand sketching and parametric modeling as two external representations used in the ideation process, we concluded that expert architects have higher levels of both PSE and CTP than novices.

title	Tracking Design Development through Decomposing Sketching Processes
source	Digital proceedings of the International Association of Societies of Design Research (IASDR 2007), Emerging Trends in Design Research, Hong Kong Polytechnic University School of Design, Hong Kong.
summary	We conducted a protocol study of the architectural sketching process. We decompose the process into process flows to explore the extent to which it expresses concept development in schematic and refined design phases. We track the development of design concepts in these phases by following the process flows of individual sketched strokes. We argue that each stroke drawn by the designer reveals a probability of an embedded concept, and that this concept is either promoted and propagated throughout the design phases, or blocked while designing. We expand the notion of lateral and vertical transformation in design by introducing a set of processes described as cross propagation, lateral promotion and vertical promotion.

title	Energy Puppet: An Ambient Awareness Interface for Home Energy Consumption
source	Digital proceedings of the 7th International Workshop on Social Intelligence Design (SID 2008), School of Architecture, Universidad de Puerto Rico, San Juan, Puerto Rico.
summary	The Energy Puppet is an ambient display device that provides peripheral awareness of energy consumption for individual home appliances. The display produces different “pet-like” behavioral reactions according to energy use patterns of the appliances to give homeowners an indication of their energy consumption status. The puppet would raise its “arms” in victory to display normal consumption rate, or its “eyes” would change color to red and “roar” to warn the homeowners when the specific appliance reaches dangerously high consumption rates. The assumption is that the awareness of energy consumption could affect how people consume and control energy use in their households. This paper describes the usage scenarios and the design and implementation of Energy Puppet and discusses future research directions.

title	TangiCAD: Tangible Interface for Manipulating Architectural 3D Models
doi	https://doi.org/10.52842/conf.caadria.2007.x.x8o
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 paper presents an interface for interacting with tangible objects to produce and edit architectural 3D models, called TangiCAD. TangiCAD is a tangible/virtual construction kit which allows architects to manipulate virtual models using easy hand control of tangible cubes, as an alternative interface for 3D modeling. It consists of a set of tangible cubes representing architectural elements, such as walls, columns, slabs,…etc., in addition to some editing operations. With more developed versions, the paper argues that architects could use tangible interfaces to carry out 3D modeling in an intuitive way, using their "flip-the-box" hands-on movement.

title	Variation from Repetition
doi	https://doi.org/10.52842/conf.ecaade.2008.791
source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 791-798
summary	Making double curvature surfaces in architectural design is nontrivial and presents many challenges. Design and fabrication of these complex shapes requires systematic approaches. Most current design and fabrication processes distribute adaptable patterns over modulated variable surfaces. But to produce variation with this method means many machining hours and a budget that a conventional architectural project cannot afford. An alternative method to achieve such complex shapes would be to overlap identical elements on a grid. This paper presents an approach to fabricate such complex surfaces from the repetition of a series of identical elements.

title	SPOT! Fetch Light - Interactive navigable 3D visualization of direct sunlight
doi	https://doi.org/10.52842/conf.ecaade.2003.117
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 117-124
summary	SPOT is a 3D environment for direct sunlight visualization. Implemented in Java 3D, SPOT features two distinct and complementary components: Time Projection and Navigable Animation for virtual interaction. SPOT supports multi-dimensional data visualization including sun angle variations with diurnal and annual cycles in threedimensional space. In SPOT users can sketch on any surface in the 3D environment to indicate the area for simulation. SPOT then generates a spatial distribution representation of the illuminance level on a selected surface over time, rendered with colors of varied gradients. SPOT also enables designers to visualize the temporal information of light distribution over time for a given point. For each point clicked on the 3D model, SPOT generates a calendar diagram where the X and Y axis represent the months of the year and the time of the day. The color of each cell of the calendar is the result of the calculation of the light amount reaching the selected point.

title	Inferring Design Intentions From Sketches: An Investigation of Freehand Drawing Conventions in Design
doi	https://doi.org/10.52842/conf.caadria.1997.217
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 217-227
summary	Designers draw to explore ideas and solutions. We look at empirical studies of the use of drawing in design, including our own work on the connection between graphic symbols and specific design concerns. We describe an empirical study on sketching for designing an architect’s office. We found that designers use different drawing conventions when thinking about different design concerns. We are implementing a freehand drawing program to recognize these drawing conventions and to deliver appropriate knowledge based support for the task at hand.

title	The Right Tool at the Right Time - Drawing as an Interface to Knowledge Based Design Aids
doi	https://doi.org/10.52842/conf.acadia.1996.191
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 191-199
summary	Designers use different symbols and diagrams in their drawings to explore alternatives and to communicate with each other. Therefore, a useful design environment should attempt to infer the designer's intentions from the drawing and, based on this inference, suggest appropriate computational tools for the task at hand. For example, a layout bubble diagram might activate design cases with similar configurations. Scribbles of view lines on a floor plan might bring up a spatial analysis tool. This research aims to develop an integrated digital sketching environment to support early design activities. The paper proposes RT, an intelligent sketch environment that provides the designers with the right tools at the right time.

title	Towards A Smart Living Environment: Happy Healthy Living With Ambient Intelligence and Technology
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	Achieving wellness is a Grand Challenge. We are concerned about the quality of life for ourselves and for our society. As human beings we want to develop and cultivate our untapped potential for a happy, healthy, creative and fulfilling life. Technological innovation may be just the key to unlock human potential for the Holy Grail of wellness. Wellness has multiple dimensions: physical, emotional, occupational, social, intellectual and spiritual (Hettler 1976). Below we briefly describe interesting design computing projects employing technological innovations to contribute toward a smart living environment for wellness.

title	Shape Based Reminding as an Aid to Creative Design
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 79-89
summary	This paper describes "Drawing Analogies", a shape based reminding program that uses freehand sketches to index and retrieve visual references for creative designing. Architects often employ reference images from books, magazines, and other visual collections to find forms they can adopt and adapt into their designs. We give examples of how designers use drawing and analogies and describe our approach to finding similar drawings. We argue that a graphical reminding scheme based on sketching can help designers find interesting references from various domains.

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 189-202
summary	The paper describes a suite of spatial analysis programs to support architectural design. Building these computational tools not only supports the task of spatial analysis for designers but it also helps us think about the spatial perception. We argue that building design software is an important vehicle for understanding architecture, using our efforts to build various visual and spatial analysis tools as examples.

doi	https://doi.org/10.52842/conf.acadia.1998.008
source	ACADIA Quarterly, vol. 17, no. 4, pp. 8-10
summary	The last thirty years have seen the development of powerful new tools for architects and planners: CAD, 3D modeling, digital imaging, geographic information systems, and real time animated walkthroughs. That’s just the beginning. Based on our experience with CAD tools, analysis of design practice, and an understanding of computer hardware and software, we’re out to invent the next generation of tools. We think architects should be shakers and makers, not just consumers, of computer aided design. We started the Sundance Lab (for Computing in Design and Planning) in 1993 with a few people and machines. We’ve grown to more than a dozen people (mostly undergraduate students) and a diverse interdisciplinary array of projects. We’ve worked with architects and planners, anthropologists, civil engineers, geographers, computer scientists, and electrical engineers. Our work is about the built environment: its physical form and various information involved in making and inhabiting places. We cover a wide range of topics – from design information management to virtual space, from sketch recognition to design rationale capture, to communication between designer and computer. All start from the position that design is a knowledge based and information rich activity. Explicit representations of design information (knowledge, rationale, and rules) enables us to engage in more intelligent dialogues about design. The following describes some of our projects under various rubrics.

title	The right tool at the right time : investigation of freehand drawing as an interface to knowledge based design tools
source	College of Architecture, Georgia Institute of Technology
summary	Designers use different symbols and configurations in their drawings to explore alternatives and to communicate with each other. For example, when thinking about spatial arrangements, they draw bubble diagrams; when thinking about natural lighting, they draw a sun symbol and light rays. Given the connection between drawings and thinking, one should be able infer design intentions from a drawing and ultimately use such inferences to program a computer to understand our drawings. This dissertation reports findings from empirical studies on drawings and explores the possibility of using the computer to automatically infer designer's concerns from the drawings a designer makes. This dissertation consists of three parts: 1) a literature review of design studies, cognitive studies of drawing and computational sketch systems, and a set of pilot projects; 2) empirical studies of diagramming design intentions and a design drawing experiment; and 3) the implementation of a prototype system called Right-Tool-Right-Time. The main goal is to find out what is in design drawings that a computer program should be able to recognize and support. Experiments were conducted to study the relation between drawing conventions and the design tasks with which they are associated. It was found from the experiments that designers use certain symbols and configurations when thinking about certain design concerns. When thinking about allocating objects or spaces with a required dimensions, designers wrote down numbers beside the drawing to reason xviii about size and to calculate dimensions. When thinking about visual analysis, designers drew sight lines from a view point on a floor plan. Based on the recognition that it is possible to associate symbols and spatial arrangements in a drawing with a designer's intention, or task context, the second goal is to find out whether a computer can be programed to recognize these drawing conventions. Given an inferred intention and context, a program should be able to activate appropriate design tools automatically. For example, concerns about visual analysis can activate a visual simulation program, and number calculations can activate a calculator. The Right- Tool-Right-Time prototype program demonstrates how a freehand sketching system that infers intentions would support the automatic activation of different design tools based on a designers' drawing acts.

summary	In creative and conceptual designing, architects often look to books, magazines, and other collections of images to find forms they can adopt and adapt in designs. On line visual collections are becoming available but typically they are indexed only with descriptive key words. We argue that in addition to key word indexing, which supports retrieval of images based on design concepts or issues, a more directly visual, graphical reminding scheme based on sketches can help designers recall interesting references from various domains. We describe Drawing Analogies, a shape based reminding program that uses hand drawn sketches to index and query visual databases.

title	What's in a Diagram That a Computer Should Understand?
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 469-480
summary	This paper reports on an experiment to test the feasibility of using a diagramming tool to access an architectural knowledge base. Our hypothesis is that designers only use a small set of conventional elements to make diagrams of architectural concepts. If this is true, then a scheme for retrieving information from computer knowledge bases using diagrams would work. Therefore we asked designers to make diagrams from texts, to interpret diagrams into texts, to pair diagrams and texts, and to comment on existing pairs from the case base. We found from the experiment that common features are shared between different designerís diagrams and texts.

summary	Designers draw diagrams to think about architectural concepts and design concerns. We are interested in programming a computer to recognize and interpret design diagrams to deliver appropriate tools for the design task at hand. We conducted empirical studies to find out if designers share drawing conventions when designing. In this paper we first discuss reasons to investigate design diagrams. Then we describe our experiment on diagramming for designing an architect's office. The experiment results show that designers use different diagramming conventions when thinking about different design concerns. We discuss and report our efforts to implement a freehand drawing program.
