summary The restoration of ancient machinery involves a number of aspects, including manufacturing procedure, materials, and scales. Portions that cannot be confirmed should be regarded as variable parameters of the reconstructed design, and therefore, there is no single result. The goal of reconstruction is to establish a prototype of ancient machinery with its mechanical engineering techniques and crafts. The problem of this study is how digital fabrication tools used in architectural design can be applied to the reconstruction of ancient machinery with the water-powered armillary and celestial tower as an example. The objective was to synthesize results that comply with historical records in a systematic, modularized, and parameterized manner and consider the feasibility of using modern digital fabrication and materials. With the procedure, we can reduce the difficulty of ancient machinery reconstruction and provide a reference for the reconstruction designs of ancient mechanical technology and crafts, and mass production made of different materials and scales in the future.

title The Combination of Design Media and Design Creativity _ Conventional and Digital Media

summary Creativity is always interested in many fields, in particular, creativity and design creativity have many interpretations (Boden, 1991; Gero and Maher, 1992, 1993; Kim, 1990; Sternberg, 1988; Weisberg, 1986). In early conceptual design process, designers used large number of sketches and drawings (Purcell and Gero, 1998). The sketch can inspire the designer to increase the creativity of the designer’s creations(Schenk, 1991; Goldschmidt, 1994; Suwa and Tversky, 1997). The freehand sketches by conventional media have been believed to play important roles in processes of the creative design thinking(Goldschmidt, 1991; Schon and Wiggins, 1992; Goel, 1995; Suwa et al., 2000; Verstijnen et al., 1998; Elsas van and Vergeest, 1998). Recently, there are many researches on inspiration of the design creativity by digital media(Liu, 2001; Sasada, 1999). The digital media have been used to apply the creative activities and that caused the occurrenssce of unexpected discovery in early design processes(Gero and Maher, 1993; Mitchell, 1993; Schmitt, 1994; Gero, 1996, 2000; Coyne and Subrahmanian, 1993; Boden, 1998; Huang, 2001; Chen, 2001; Manolya et al. 1998; Verstijinen et al., 1998; Lynn, 2001). In addition, there are many applications by combination of conventional and digital media in the sketches conceptual process. However, previous works only discussed that the individual media were related to the design creativity. The cognitive research about the application of conceptual sketches design by integrating both conventional and digital media simultaneously is absent.

title How to Improve Creativity: Can designers improve their design creativity by using conventional and digital media simultaneously?
source Computer Aided Architectural Design Futures / 978-1-4020-6527-9 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Futures / 978-1-4020-6527-9] Sydney (Australia) 11–13 July 2007, pp. 571-583
summary From previous works, we know that the distinguishing characteristics of design media cause different influence on design creativity. However, the cognitive research about the application of conceptual sketches design by integrating both conventional and digital media simultaneously is absent. In this research, we would like to discuss that can it inspire more creative works if designers use conventional and digital media simultaneously as sketching media to generate conceptual sketches. The results show that using conventional and digital media simultaneously comparing with only using individual media can help arouse creative thinking, cognitive activity and design outcome in the stage of conceptual sketches design. The findings may suggest that the integration of various design media provides one feasible ways to inspire creativity, which can apply to the design training of creativity on education and to the designer’s practical operation, but initiates more possibility of new media to assist design.

summary Gamification is the application of game-oriented design approaches or game-inspired mechanics to otherwise non-game contexts. Mobile guiding system is the design process of information interactions. It is the integration of information design, interaction design, and sensorial design. The e-learning system of mobile guide is able to be loaded gamification concepts and let mobile learning interestingly, diversely, and validly. The problem of the research was if we combined the concept of gamification design into museum guide services with augmented reality for non-commercial purposes, it also provided the same benefits to the promotion of museum learning and knowledge, integrating mobile devices as navigation media. It would improve more users to participate in a museum and use the guide system actively, and then arise their interest and achievement. The result was to establish a preliminary model for developing a museum mobile guide system of gamification design and augmented reality.

summary Beaver dams are formed by two main processes. One is that beavers select proper woods for constructing. The other one is that streams aggregate those woods to be assembled. Using this approach to construction structure is suitable for natural environment. In this paper, we attempt to develop a construction process which is suitable for all-terrain construction robot in the future. This construction process is inspired by beavers' construction behavior in nature. Beavers select proper sticks to make the structure stable. We predict that particular properties of sticks contribute gravity-driven assembly of wood structure. Thus, we implement the system with machine learning to find proper properties of sticks to improve selection mechanism of construction process. During this construction process, 3D scanner on robotic arm scans and recognizes sticks on terrain, and then robot will select proper sticks and place them. After placement, the system will scan and record the results for learning mechanism.

summary In this research, we attempt to develop a tool which integrates certain common geographic information from OpenStreetMap and OpenTopography into Grasshopper. We name it as OSMKIT temporarily. Besides, in order to make the integration in the design process easier, this tool includes the bilateral conversion function of coordinate in Rhinoceros 3D and the coordinate of the World Geodetic System. These characteristics bring about several possibilities for further usage. This paper contains explanations of functions and examples. For instance, it can be employed for data visualization on a map when these data contain coordinate information. Additionally, since this tool is simple and intuitive to convert points into GPS coordinates, it can make users plan drone for photogrammetry and deal with other related tasks on the rhinoceros 3D interface, helping them to gain most current urban models. Moreover, architects or designers can be not only users but also contributors for open source map system such as OpenStreetMap; the process of sharing the mode which user measure is demonstrated in this paper. To sum up, this coordinate system based tool is designed to be multifunctional and suitable for interdisciplinary usages in grasshopper.

summary The integration of Robot Operating System (ROS) with Human-Machine Collaboration (HMC) currently represents the future tendency toward Autonomous Robotic In-Situ Assembly on Construction Sites. In comparison with the industrial environment, construction sites nowadays are extremely complex and unpredictable, due to the different building components and customized design.This paper presents a visual-based object recognition method and user interface enabling on-site robot arms to autonomously handle building components, to build specific designs without the influence of material, shape, and environment. The implementation is an object recognition approach that serves with KUKA industrial robotic manipulator along with an RGB-depth stereo camera in an eye-in-hand configuration to grasp and manipulate found elements to build the desired structure. Opportunities for using vision-based autonomous robotic in-situ assembly on construction sites are reviewed.

title Parametric Modelling and Simulation of an Indoor Temperature Responsive Rotational Shading System Design
doi https://doi.org/10.52842/conf.caadria.2020.1.579

summary We present a digital design strategy for developing an intelligent rotational shading system responsive to changes in indoor temperatures. The strategy was first modelled with an Arduino-based physical prototype, identifying the concept of "mapping" between building indoor air temperature and rotational movement (angle) of external solar shading. A virtual parametric modelling approach was then followed to test three methods of mapping: linear, quadratic and logarithmic. The aim was to examine the performative differences exhibited by the three mapping methods in terms of the total comfort hours and estimated cooling energy demand during summer months. A typical cellular office in the Arts Tower of University of Sheffield was chosen for the parametric modelling (Rhino-Grasshopper) and environmental simulation (Honeybee-Ladybug) of horizontal and vertical rotational shading system design. The simulation shows that the horizontal shading system rotating according to the linear mapping methods achieve greater total comfort hours with lower cooling energy demand in the case of Arts Tower in Sheffield, UK.

summary Historically, the discipline of Architecture experiences time lags in its incorporation of novel philosophical ideas, technology, social ideas and so on, thanks to the inertia brought about by the building process of any built space. So, how has this concrete entrenched discipline taken on the business of Information Technology in this Information Age? In a 99% wired up 'Intelligent Island' with the national IT master plans created every 5-10 years, how has architectural practices adapted to these changes? What are the factors surrounding IT in architectural firms and how does this affect their adoption of IT. What role should architecture play in a 'Knowledge Economy'?

summary To explore how mobile digital tools can bring students out from isolated classrooms, we tested several for use in design studio site visits. We focused on small, off-the-shelf tools that are inexpensive and easy to upgrade. In this paper we identify the logistical, efficiency, and learning considerations for the selection and introduction of mobile digital tools , with observations about device usability and administration that are applicable to other kinds of technology introduction. We found that adoption of a tool depends on several factors, including ease of use and inconspicuous nature. Compared to traditional tools, most of these tools require a great deal of set-up time before students can use them efficiently. In addition, they require docking with a computer to analyze the information collected in the field. As a result, most of the learning takes place in the studio, rather than in the field. Our eventual goal is to clarify the potentials of place-recording tools, making it easier to gather and use a toolkit for specific situations.

title Digital Identity in the Virtual Design Studio
source Constructing Identity: the Associated Collegiate Schools of Architecture (ACSA) 56th Annual Meeting Proceedings, Cleveland, Ohio
summary Internet tools most effectively connect diverse groups when individuals involved experience vital human connections. Online strangers are pulled into a community in which they can see a friendly face in the crowded stream of information. Strong self expression engages an audience and can result in personal interactions which reward getting beyond the technology. A group of individual profiles can coalesce to give colorful definition to team biases, strengths and weaknesses. This paper examines how the expression of identity has been a critical factor in the success of Internet design collaborations. First, it provides context on how these projects can improve architectural education by increasing relevance. Second, it identifies opportunities for individual and team expression gathered from a series of annual international design exercises known as the Virtual Design Studio. Third, it explains strategies for fostering student expression and interaction. Finally, it cites areas for future investigation.

summary This paper explains the logistical and technical issues involved in design collaboration and how to address them strategically in projects for design, teaching and research. Five years of arranging projects, studying peer results and involving novices in exchanges point out the benefits and pitfalls of Internet partnering. Rather than a single universal technical solution, multiple solutions exist: Technical means must be tailored to specifics concerning the task and participants. The following factors need to be considered in finding the best fit between technology and group design: 1) Collaboratorsí profiles, 2) Mutual value of produced information, 3) Collaboration structure, and 4) Logistical opportunities. The success of a virtual studio depends upon clear task definition, aligned participant expectations and suitable engagement methods. We question the efforts required in the installation of expensive technologies for communication and visualization. Often technical systems support ancillary and non-beneficial activity.

source Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 173-188
summary By looking at computer aided design as design communication we can use pedagogical methods from the well-developed discipline of language learning. Language learning breaks down a complex field into attainable steps, showing how learning strategies and attitudes can enhance mastery. Balancing the linguistic emphases of organizational analysis, communicative intent and contextual application can address different learning styles. Guiding students in learning approaches from language study will equip them to deal with constantly changing technology.

From overall curriculum planning to specific exercises, language study provides a model for building a learner-centered education. Educating students about the learning process, such as the variety of metacognitive, cognitive and social/affective strategies can improve learning. At an introductory level, providing a conceptual framework and enhancing resource-finding, brainstorming and coping abilities can lead to threshold competence. Using kit-of-parts problems helps students to focus on technique and content in successive steps, with mimetic and generative work appealing to different learning styles.

Practicing learning strategies on realistic projects hones the ability to connect concepts to actual situations, drawing on resource-usage, task management, and problem management skills. Including collaborative aspects in these projects provides the motivation of a real audience and while linking academic study to practical concerns. Examples from architectural education illustrate how the approach can be implemented.

summary One of the challenges faced by digital design teachers is how to fit our piece into the larger puzzle of architectural education. How can we make computing support architecture’s varied endeavors and thinking modes? Students must be able to explore and communicate design ideas fluidly using digital or traditional media, as suitable to specific queries. We need to expose students to a palette of current and emerging techniques and help them develop a personal set of media skills.

summary This paper examines the effectiveness of animated versus non-animated drawings as teaching tools. Data was collected by comparing how architectural design students given an animation versus those given a static, six-panel storyboard are able to learn processes in a space-planning design problem. All subjects were given an example of an expert design drawing, asked to put the design steps in order, and then to follow those steps in performing a similar design problem. Their responses were recorded with a digital pen-on-paper system that automatically generates vector animations. The animations can then be immediately viewed on a computer for stroke-by-stroke review. Finally, each student’s animation was analysed in terms of design process steps and compared with the expert example. While those given animations performed only marginally better on the survey of steps, they were better able to imitate the order of expert steps. Furthermore, reviewing the examples by computer revealed common errors that students could modify for more successful design strategies. The following discussion examines methods for researching design process with the digital pen, along with shortcomings, advantages and directions for further study.
