summary	In 1990, due to the traditional architecture design and construction method difficult to build the complicated and non-geometry free-form Fish Structure in Barcelona, architect Frank Gehry started learn from the field of aerospace to utilize CAD/CAM technology in design and manufacture process. He created the free-form fish model in CAD system and exported the digital CAD model data to CAM machine (RP and CNC) to fabricate the design components, and finally assembled on the site. Gehry pioneered in the new digital design process in using CAD/CAM technology or so-called digital fabrication. It becomes an important issue recently as the CAD/CAM technology progressively act as the new digital design media in architectural design and construction process (Ryder et al., 2002; Kolarevic, 2003). Furthermore, in the field of architecture professional, some commercial computer systems had been developed on purpose of standardizes the digital design process in using CAD/CAM fabrication such as Gehry Technologies formed by Gehry Partners; SmartGeometry Group in Europe and Objectile proposed by Bernard Cache. Researchers in the research field like Mark Burry, Larry Sass, Branko Kolarevic, Schodek and others are enthusiastic about the exploration of the role of CAD/CAM fabrication as new design media in design process (Burry, 2002; Schodek et al., 2005; Lee, 2005).

title	G Pen: An Intelligent Designer’s Playmate
doi	https://doi.org/10.52842/conf.acadia.2003.403
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. 403-409
summary	In the field of design the pen-based system is a newly developed computer interface that provides the designer with the convenience of a pen in freehand sketches. But these pen-based systems only focus on an interface familiar to the designers and the application of the hardware and software that go with it, treating the pen only as a mouse-like input device. As pen and pad are devices for the pen-based system, the hope is that they can be endowed with more intelligent characteristics to let them interact with designer’s gestures and become a creative source for the designers, while simultaneously preventing the design fixation encountered by designers during design process. This research utilizes the unintentional hand gestures made by designers, such as the designer’s grip of the pen or movement involved in playing with the pen, putting it down, knocking it, twisting it or shaking it, during the thinking process or when running into a design fixation. From the interaction between the pen and the pad, certain actions may be generated to stimulate the designer’s thinking process. This research uses a neural network as the main learning mechanism for the eventual development of a prototype of a pen-based drawing system that provides timely visual stimulation: a G Pen system.

title	Is a pen-based system just another pen or more than a pen?
doi	https://doi.org/10.52842/conf.ecaade.2003.615
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 615-622
summary	Freehand sketch is the most critical stage in the design process. The importance of the freehand sketch is in its ability to freely represent various projections of ambiguous drawing using a convenience tool, pen-and-paper. Recently, pen-based system which developed attempted to use pen as an input device, allowing sketches to be freely drawn on computers. However, as far as the various drawing projections, such as diagram, symbol, plan, elevation, section, perspective, etc., how are they interrelated to a designer’s cognitive behavior? Different media have different abilities to represent projections. What’s the difference of design cognitive behavior between conventional pen-and paper and pen-based system in view of both using a pen as a design medium? This research proceeds a think-aloud protocol analysis to present an analysis and discussion. Research results show that there is a relationship of gradual embodiment, mutually complementary, going from a whole to being dissected into sections between the different projections. Moreover, pen-based system is more than a pen, it allows designer to inspect a 3-D view during the sketching stage. This gives the designer more opportunities during the sketching stage to conduct the design thinking process based on the ambiguous 2-D projections and the more concrete 3-D images, as well as more opportunities for visual feedback

title	An Insight into the Freedom of Using a Pen: Pen-based System and Pen-and-paper
doi	https://doi.org/10.52842/conf.acadia.2003.385
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. 385-393
summary	In earlier researches on freehand sketching, the cognitive behavior of designers was studied. In recent years, some researchers began to look into this area from the design media aspect. The pen-based system, developed by Gross, Landay and other researchers, used the pen as an input device, allowing sketches to be freely drawn in a computer environment. The importance of the freehand sketch lies in its ability to freely represent various drawing projections using ambiguous sketches. However, as for the various drawing projections, such as diagrams, symbols, plans, elevations, sections, perspectives, etc., how are they interrelated to a designer’s thinking process and the cognitive behavior? Different media have different abilities to represent different projections. Would they affect the designer’s design thinking as well? Targeting different media, i.e., conventional freehand sketches vs. the computer pen-based system, this research uses case studies and think-aloud protocol analysis to present an analysis and discussion. Research results show that there is a relationship of gradual embodiment that is mutually complementary, going from a whole perspective to being the dissected into sections between the different projections. In addition, these projections restrict the designer’s various design thinking processes, while the use of different media may somewhat change the actual design thinking of the designer

summary	Along with the development of computer technologies and CAD/CAM, digital tools are increasingly adapted in architectural design. Developed thus far, functions of digital tools are no long limited to two-dimensional drafting or final presentation; they have become tools that can assist design thinking. Because of the involvement of digital tools, the design process has been greatly affected; or, one may say that digital tools liberated the confines of forms and structuring of architectures. This research aims to explore the procedures in the design process using digital tools. In the conclusion, we found that in an attempt to abridge the gap between design ideas and actual implementation, the designer used the digital reality simulation function very frequently to assist in decision making, and in order to process more complex and freer forms, the designer relied on the 3D design environment to carry out his thinking process and amendments. In addition, the digital design process is mainly conducted through the methods of 1, 3D modeling, 2, Simulation, 3, Generation, and 4, Fabrication. The steps and methods in the digital design process are obviously different from the traditional ones, which focus mainly on mass-production of 2D drawings; therefore, it is certain that the new tools will change the outcome of the designs.

summary	This study aims to explore the possibility of maintaining intuitive behavior patterns and the most natural relationship coming from physical touch between human and object as interaction behaviors in interaction designs. Such an interaction will convey affection while providing brand new applications and innovative experiences offered by digital technology. Interactive behavior is natural, but the experience of affection is novel is the core idea of the interaction design in this study. The study aims to use a familiar artifact in daily life as the main carrier and embed technology in them and activate them, enabling them with sensitive sensing ability. With such an ability, the interaction between human and objects is thus sensed in a pattern of touch, which itself is affective and interactive. Interactions at the proper time can be provided as feedback, allowing users to experience emotional interaction. Through the analysis of the authors six interaction design projects and experiments over 10 years, the design process and framework for emotional tactile interaction design in using a familiar artifact is proposed.

title	Presence Stickers: A Seamlessly Integrated Smart Living System at a Solitary Elderly Home
doi	https://doi.org/10.52842/conf.caadria.2022.1.445

summary	This research develops Presence Stickers, the capacitive sensing module that can be easily affixed to the existing space element surfaces (such as a wall, door, stairs), and daily objects or home furniture (such as a chair, cabinet, table, sofa, etc.). These 30*30 cm Presence Stickers can actively sense people‚s physical behaviors and body movements in spaces. From the preliminary analysis of observing the 80-year-old elderly subject‚s daily activities, the movement trajectory of the ‚Move-Stop‚ pattern is found. There will be a Touch (T) and Touchless (TL) relationship between the body and the space elements or objects. Furthermore, the touchless, or non-contact, intimate relationship can also be divided into two types: 1. The body that ‚Passes by‚ (P) the spatial elements or objects, and 2. The body that ‚Stays‚ (S) in front of the object and performs activities. These three types of the intimate relationship between bodies and objects, i.e., T, TL-P, and TL-S, were used as the main sensing conditions to develop the Presence Stickers sensor module. We affixed 8 Presence Stickers on 9 objects in six spaces and finally, the life pattern can be analyzed and the sensors provide the customized intelligent application function for the elderly.

summary	This research develops a robotic arm-controlled wax material fluidity shape/form-making system that combines AI image recognition and remote control capabilities. AI image recognition is used to capture the designer's hand gestures or movements as an intuitive input method for controlling shape forming. It gives the designer active control of the desired model shape through the temperature, rotation, and movement controls in the process of phase change of wax materials. The system has the additional advantage of remote control, allowing designers to create wax models remotely through intuitive gesture-controlled interactions. This advantage will become a new method of the digital co-creation process.

summary	This study explores the integration of Artificial Intelligence-Generated Content (AIGC) in design processes, focusing on the ideation phase. Utilizing in-depth interviews with experienced designers and an experimental approach with novices, it compares AIGC tools like ChatGPT, Midjourney and Copilot with traditional sketching methods. The findings reveal two distinct operational patterns in AIGC utilization: a subtractive method of refining AI outputs and an additive method of evolving design through AI suggestions. Experienced designers view AIGC as a powerful aid for creative ideation, while novices prefer familiar hand-drawing methods. The study proposes a "Seeing-Instructing-Seeing" model, adapting Schön's reflective practice model, to incorporate the collaborative dynamic between designers and AI, marking a shift from manual to intellectual labor in design ideation. This represents a paradigm shift in design methodologies, suggesting a future of co-creative partnerships between designers and AI tools.

summary	Innovative media made a varied representation of urban and architectural spaces. However, the interaction between human and the space requires other new media to present. In this research, based on experts’ opinions about future space and lifestyle, we create a creative scenario and produce a video through video camera, digital image process, computer animation. In addition, virtual studio, camera matching and motion capture are added to simulate how people would interact with the spaces in the city life.

summary	Design Media is the tool designers use for concept realization (Schon and Wiggins, 1992; Liu, 1996). Design thinking of designers is deeply effected by the media they tend to use (Zevi, 1981; Liu, 1996; Lim, 2003). Historically, architecture is influenced by the design media that were available within that era (Liu, 1996; Porter and Neale, 2000; Smith, 2004). From the 2D plans first used in ancient egypt, to the 3D physical models that came about during the Renaissance period, architecture reflects the media used for design. When breakthroughs in CAD/CAM technologies were brought to the world in the twentieth century, new possibilities opened up for architects.
