summary	The paper is giving an overview and analysis of an undergraduate, sixth semester, compulsory course titled “Virtual Reality: Interactive Spatial Design” at the department of Architecture, School of Engineering, University of Thessaly, Volos, Greece. It is one of the very few courses on designing digital/synthetic and interactive space_and not merely utilising Virtual Reality (VR) technologies for architectural visualisations_in architectural curricula. The aim of this paper is to primarily draw on a ten year experience on teaching the course and to open up a discussion on the implications of such digital design courses and address emerging problems. This is achieved through a reflection on the teaching process (interaction as design process, curriculum and attained goals) and an analysis and genre classification of the 150 submitted projects.

summary	This paper explains potential benefits of indirect biofeedback used within interactive virtual environments, and reflects on an earlier study that allowed for the dynamic modification of a virtual environment’s graphic shaders, music and artificial intelligence (of Non Playing Characters) based on the biofeedback of the player. It then examines both the potential and the issues in applying biofeedback (already effective for games) to digital architectural environments, and suggests potential uses such as personalization, object creation, atmospheric augmentation, filtering, and tracking.

title	Navigating Complex Models in Collaborative Work for (Sustainably) Integrated Design
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 619-636.
summary	Increasingly intensive use of computational techniques such as parametric-associative modeling, algorithmic design, performance simulations and generative design in architecture, engineering and construction are leading to increasingly large and complex 3D building models which in turn require increasingly powerful techniques in order to be manipulated and interpreted effectively. Further complexities are of course due also to the multi-disciplinary nature of building projects, in which there can be significant variation and even conflict among the aims of architects, engineers and builders, as well as owners, occupants and other stakeholders in the process. Effective use of model information depends to a large extent on sense-making, which can in some ways be helped but also hindered by schemes for organizing the information contained. Common techniques such as layering, labeling (aka ‚Äòtagging‚Äô) and assignment of various other attributes to model objects have significant limitations ‚Äì especially those arising from general problems of language, ontology and standardization, as well as but distinct from issues of interoperability ‚Äì both with respect to locating the desired items in a 3D building model and also with respect to displaying the objects in informative ways which effectively assist collaborative design and decision-making. Sustainable design in particular is an area generally requiring a high level of inter-disciplinary collaboration to achieve highly integrated designs which make multiple use of the elements and systems incorporated (though integrated design may also be pursued without explicit aims of sustainability). The proposed paper describes ongoing research concerning alternatives to the currently common techniques for locating and displaying information in 3D building models in support of sense-making to promote collaborative and integrated design. These alternatives comprise on the one hand interactive geometric-content-based methods for search and classification of model objects ‚Äì as an alternative or complement to common assigned-attribute-based methods ‚Äì and on the other hand visual analytic techniques ‚Äì in contrast to existing, relatively static tabular and "physical" views ‚Äì which can help to increase the informativeness of the geometric data within the model, as well as the non-geometric data that is attached to geometric objects (e.g. as in the cases of BIM and various types of CAE performance simulations). Tests undertaken with architects and engineers in practice and academia to evaluate the proposed methods are also described. Finally conclusions are drawn regarding these methods‚Äô positive present performance and some of their shortcomings, as well as indicating directions for future research concerning the methods‚Äô refinement and extension to help 3D building models become more effective components of the design process than they are at present, both with respect to these models‚Äô present levels of complexity and especially with respect to their anticipated increasing complexity in future.

title	Multi-touch - the future of design interaction
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 557-572.
summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

title	Packing the “Chinese box”: A strategy to manage knowledge using architectural digital models
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 717-726
doi	https://doi.org/10.52842/conf.caadria.2011.717
summary	The architectural design activity has been transformed due to technological advances in building knowledge management. The research proposed is based on a three years long Ph.D. work on 3D models intended as graphical informative systems, layered according to the “Chinese box” paradigm and destined to professionals and researchers in architecture. The applied case study is referred to San Vitale’s church in Ravenna, Italy: the monument was investigated through nested digital models produced by different computer programs. Passing through evolutionary steps identified as synthesis, reduction and projection, the resulting archive lowered its Complication Ratio, a numerical value inspired by fractal’s auto-similarity, indicating a recursive modification in morphologies and contents. Models so conceived are qualified as progressive knowledge-based catalogues easily interchangeable and useful to understand how new or existing architectures work. As a result of this approach, representations obtained with surveys, historical chronicles, light analysis and acoustic simulations were composed following gradual refinements: technical data were collected running parallel to bibliographic research, enriching interactive virtual models sprung from a recursive criterion destined to increase the information enclosed into an undivided, lossless, digital archive.

title	Architecture = Computer‚ from Computational to Computing Environments
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 217-232.
summary	Drawing on architecture, urban digital media, engineering, IT and interaction design, the research presented in this paper outlines a possible shift from architecture designed through computation (any type of process, algorithm or measurement done in a computational matter) towards architecture capable of computing (developing, using and improving computer technology, computer hardware and software as a space-defining element). The research is driven by recent developments in four fields, as follows: (a) Architecture in its recent development has shifted from a planar box, as was the ideal in the modernist movement, towards complex and non-standard forms. (b) The design concepts of non-standard surfaces have been adopted into media facades and media architecture by liberating the pixel from its planar position on a screen [1]. (c) Advancements in pervasive computing applications are now able both to receive information from the environment in which they are used and to detect other devices that enter this environment [2]. (d) Developments in advanced autonomous systems such as Human Computer Interaction (HCI) or Human Robot Interaction (HRI), have produced intelligent systems capable of observing human cues and using these cues as the basis for intelligent decision-making [3]. Media fa_ßade developments work in the direction of the above-mentioned four fields, but often come with limitations in architectural integration; they need additional components to interact with their environment and their interactions are both often limited to visual interactions and require the user to act first. The researched system, Polymedia Pixel [4] discussed in this paper, can overcome these limitations and fulfil the need for a space-defining material capable of computing, thus enabling a shift from architecture designed by computation towards architecture capable of active computing. The Polymedia Pixel architecture merges digital technology with ubiquitous computing. This allows the built environment and its relation with digital technology to develop from (a) architecture being represented by computer to (b) computation being used to develop architecture and then further to where (c) architecture and the space-defining objects have computing attributes. Hence the study presented aims to consider and answer this key question: ‚ÄòWhen building components with computing capacity can define space and function as a computer at the same time, what are the constraints for the building components and what are the possible advantages for the built environment?‚Äô The conceptual framework, design and methods used in this research combine three fields: (a) hardware (architecture and design, electronic engineering) (b) software (content design and IT) and (c) interaction design (HCI and HRI). Architecture and urban design determinates the field of application. Media architecture and computer science provide the technological foundation, while the field of interaction design defines the methodology to link space and computing [5]. The conceptual starting point is to rethink the application of computers in architecture and, if architecture is capable of computing, what kind of methodology and structure would find an answer to the above core research question, and what are the implications of the question itself? The case study discusses opportunities for applying the Polymedia Pixel as an architectural component by testing it on: (a) constraint testing ‚Äì applying computational design methodologies to design space (b) singular testing - discussing the advantages for an individual building, and (c) plural testing ‚Äì investigating the potential for an urban context. The research aims to contribute to the field of knowledge through presenting first steps of a System < - > System mode where buildings can possibly watch and monitor each other, additional to the four primary interactive modes of operation. This investigation, its proposed hypothesis, methodology, implications, significance and evaluation are presented in the paper.

doi	https://doi.org/10.52842/conf.caadria.2011.281
summary	This paper points out that “interaction” is not only a scientific issue but also a social-cultural issue. The relationship between the user experiences and the behaviours of the system should be emphasised. The “Individual-Intelligible” coordinate system is created to compare and evaluate the interactivity of various systems, it provides a new design space for researches or students experimenting with interactive systems. Four experiments are discussed with the new formulation of the interaction.

title	Structural form generation using interactive genetic algorithm
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 751-760
doi	https://doi.org/10.52842/conf.caadria.2011.751
summary	Structural form design could be considered as a bi-objective problem which should satisfy both the efficiency criterion of structural engineering and the aesthetic criteria of architects. This research tries to introduce Interactive Genetic Algorithm (IGA) in the problem of structural form design. It combines the structural analysis performed by computer and aesthetic evaluation by architects into a bi-objective IGA process, in order to generate structural forms which are preferred by the architects and at the same time structurally optimal. In this research, the structure generated consists of two kinds of members, truss and beam. Generation and evolution of structure is based on a triangular element composed of several members. Through experiment of the IGA structural form design system, it is found the structure forms are optimized as the evolutionary process proceeds, and the aesthetic preference of architect is also transferred from generation to generation. It is also revealed that the two criteria have mutual restrictions, which resulted in compromised results.

title	Integrative Design Strategies for Multimedia in Architecture

summary	Multidisciplinary efforts that have shaped the current integration of multimedia into architectural spaces have primarily been conducted by collaborative efforts among art, engineering, interaction design, informatics and software programming. These collaborations have focused on the complexities of designing for applications of multimedia in specific real world contexts. Outside a small but growing number of researchers and practitioners, architects have been largely absent from these efforts. This has resulted in projects that deal primarily with developing technologies augmenting existing architectural environments. (Greenfield and Shepard 2007)This paper examines the potential of multimedia and architecture integration to create new possibilities for architectural space. Established practices of constructing architecture suggest creating space by conventional architectural means. On the other hand, multimedia influences and their effect on the tectonics, topos and typos (Frampton 2001) of an architectural space (‘multimedia effects matrix’) suggest new modes of shaping space. It is proposed that correlations exist between those two that could inform unified design strategies. Case study analyses were conducted examining five works of interactive spaces and multimedia installation artworks, selected from an initial larger study of 25 works. Each case study investigated the means of shaping space employed, according to both conventional architectural practices and the principles of multimedia influence (in reference to the ‘multimedia effects matrix’) (James and Nagasaka 2010, 278-285). Findings from the case studies suggest strong correlations between the two approaches to spatial construction. To indicate these correlations, this paper presents five speculative integrative design strategies derived from the case studies, intended to inform future architectural design practice.

title	Spatial Experience in Real & Virtual Environment as an Urban Design Tool
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 59-64
summary	The innovations of information technologies and the new possibilities of multimedia exploitation in the realm of architectural design and education are supporting the development of image communication methods on the basis of interactivity. The creative process of searching and decision-making in the urban design studio of our Faculty is supported by spatial modeling methods. The draft is sketched in modeling material on a working model. From the didactic point of view, relevant are mainly those phases, in which is possible, in the imaginative way, to support the searching and decision making process with the aim to test, compare and continuously evaluate the fulfillment of the hypothetic intentions of the solution responsibilities. The model becomes an interactive medium of cooperation between teacher and the working group of students. From the view of design crystallization, the dominant phases, in the creative process, are examining, verification, and simulation. The alternatives of material-compositional content and the spatial performance charts of modeled physical structure are verifying and the visual experience of the anticipated urban environment is simulated by the author, but also through the future client’s eyes. The alternation of the composition’s spatial configurations is generally appreciated by the static visual verification in the endoscopic horizon like the architectural spatial studies. The effective method of the progress generates a creative atmosphere for the generative thinking and design. The laboratory simulation of spatial experiences and their evaluation is performed following the perception psychology relations. The simulation of digestion of the new spatial reality intervenes the customer’s identification and guides to subjective approaches towards the quality and complexity of the formed environment. The simulation is performed in motion in order to be able to anticipate the dynamic continuity of subjective spatial imagination. The induced atmosphere will direct the evaluational attitudes of authors on comparison and selection of the successful alternatives. In our fee, we will present the demonstrations of selected static and dynamic notations of image sequences prepared in our laboratory. The presentations have been created in order to analyze, verify and offer imaginative support to creative findings in result of fulfilling the studio design tasks in the educational process. The main one is the design of urban spatial structures. The laboratory methodology is in the first place oriented on the analogue-digital procedures of "endoscope" model simulation. At the same time it also explores and looks for new unconventional forms of visual communication or archiving as imagination support to specialist and laymen participants in creative, valorization and approval processes.

title	Graph visualization in computer-aided design: An exploration of alternative representations for GenerativeComponentsTM Symbolic View
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 133-142
doi	https://doi.org/10.52842/conf.caadria.2011.133
summary	In this paper we explore graph models used to illustrate the relationships between elements of designs in computer-aided design (CAD) systems. We discuss common limitations and ways to make such representations more usable and interactive. In order to study common problems of symbolic representations in CAD systems, we conducted a survey of a number of CAD applications that employ graph representations in their interface and provided comparative analysis of the properties of graph representations in these systems. As a case study we used Bentley GenerativeComponentsTM (GC) system - a parametric CAD application that uses graph (“symbolic”) view to visualize the structure of design. We conducted series of interviews with expert GC users that revealed many limitations of the GC symbolic view. To address these limitations, we developed alternative representations of symbolic view that aim at enhancing user experience with the system and reviewed these with expert GC users. As a result of our study, we developed a set of interactive prototypes using SHriMP1 visualization tool and Processing programming language. These provide improved ways of user interaction with symbolic representation, including better readability of the graph and, as a result, an improved support for design model analysis.

summary	In this paper, we describe a system of composite images to design virtual three-dimensional structures in an outdoor environment. The system, called AmbiViewer, consists of a modeler for three-dimensional on-site sketching, and overlapping locative technologies to orient virtual objects in a real-space, real-time setting. The system employs both GPS orientation and a visual marker system to provide a realistic and interactive augmented reality interface. While it is still under development, the authors believe it can bridge the gap between sketching on site, and creating virtual models in the office.

title	Computational landscape design with the seed scattering system: A case study in the Sony forest project
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 49-58
summary	This paper proposes a computational landscape design method, called the seeds scattering system (SS system), which enables us to manage various environmental parameters in design processes, to create the ‘natural forest’ in urban environments. First, this paper discusses the drawbacks of the conventional methods for landscape design. Second, the paper outlines the components of the SS system together with the design process of the SONY forest project in Tokyo, and shows its advantages, including broad applicability to conceptual design, and capability of environmental simulations and spatial optimizations. Last, the paper summarizes the effectiveness of the SS system. By managing fundamental rules behind geometries in forest growth processes, the SS system showed us capability for constructing interactive relationships between design and their surrounding environments to produce design inherent in its site.

title	Sensitive Voxel - A reactive tangible surface
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 525-538.
summary	Haptic and tactile sensations, the active or passive exploration of our built surroundings through our sense of touch, give us a direct feeling and detailed information of space, a sense of architecture (Pallasmaa 2005). This paper presents the prototype of a reactive surface system, which focuses its output on the sense of touch. It explains how touch sensations influence the perception of architecture and discusses potential applications that might arise from such systems in the future. A growing number of projects demonstrate the strong impact of interaction design on the human senses and perception. They offer new ways of sensing and experiencing architectural space. But the majority of these interaction concepts focus on visual and auditory output-effects. The sense of touch is typically used as an input generator, but neglected as as a potential receiver of stimuli. With all the possibilities of sensors and micro-devices available nowadays, there is no longer a technical reason for this. It is possible to explore a much wider range of sense responding projects, to broaden the horizon of sensitive interaction concepts (Bullivant 2006). What if the surfaces of our surroundings can actively change the way it feels to touch them? What if things like walls and furniture get the ability to interactively respond to our touch? What new dimensions of communication and esthetic experience will open up when we conceive of tangibility in this bi-directional way? This paper presents a prototype system aimed at exploring these very questions. The prototype consists of a grid of tangible embedded cells, each one combining three kinds of actuators to produce divergent touch stimuli. All cells can be individually controlled from an interactive computer program. By providing a layering of different combinations and impulse intensities, the grid structure enables altering patterns of actuation. Thus it can be employed to explore a sort of individual touch aesthetic, for which - in order to differentiate it from established types of aesthetic experiences - we have created the term 'Euhaptics' (from the Greek ŒµœÖ = good and Œ¨œÄœÑœâ = touch, finger). The possibility to mix a wide range of actuators leads to blending options of touch stimuli. The sense of touch has an expanded perception- spectrum, which can be exploited by this technically embedded superposition. The juxtaposed arrangement of identical multilayered cell-units offers blending and pattern effects of different touch-stimuli. It reveals an augmented form of interaction with surfaces and interactive material structures. The combination of impulses does not need to be fixed a priori; it can be adjusted during the process of use. Thus the sensation of touch can be made personally unique in its qualities. The application on architectural shapes and surfaces allows the user to feel the sensations in a holistic manner ‚Äì potentially on the entire body. Hence the various dimensions of touch phenomena on the skin can be explored through empirical investigations by the prototype construction. The prototype system presented in the paper is limited in size and resolution, but its functionality suggests various directions of further development. In architectural applications, this new form of overlay may lead to create augmented environments that let inhabitants experience multimodal touch sensations. By interactively controlling the sensual patterns, such environments could get a unique ‚Äútouch‚Äù for every person that inhabit them. But there may be further applications that go beyond the interactive configuration of comfort, possibly opening up new forms of communication for handicapped people or applications in medical and therapeutic fields (Grunwald 2001). The well-known influence of touch- sensations on human psychological processes and moreover their bodily implications suggest that there is a wide scope of beneficial utilisations yet to be investigated.

title	Second-order prosthesis: Human-aided design within the expanded field of ecology

summary	This paper defines second-order prosthesis in which the human subject, by virtue of her corporeality or imagination, is resourced by a technological system. Underpinning this definition is Massumi’s notion of asymmetrical, symbiotic prosthesis and the second- order cybernetic challenge to objectivity. Through the case study of an immersive, sensor-based, interactive artwork, it is found that there are resonances between technology engaged in second-order prosthesis and the ideology of biology. Notions of survival, reproduction and evolution become a critical part of second-order prosthetic discourse and an expanded field of ecology is identified as the territory of analysis for resulting techno-human relations. A second case study explores computer-aided design (CAD) and virtual space. This study confirms the status of the technological in an expanded ecology as both CAD and virtual space resource imagination in the production of human-aided design.

summary	The motivation behind the CDP interdisciplinary research project is to resolve the current discrepancy between familiar, analogue ways of working in the early architectural design stages and the ever increasing use of digital tools in office practice. The project’s objective is the conception and prototypical realisation of an interactive work environment for use in the early design phases. By directly linking familiar analogue ways of working with digital computer aided design tools, the CDP represents a working environment that allows designers to work the way they are used to while making use of the potential of computers. This paper describes the first results of a design environment for supporting the conceptual phase of urban design.

title	Development of the Seed Scattering System for Computational Landscape Design
source	International Journal of Architectural Computing vol. 9 - no. 4, 421-436
summary	This paper proposes a computational landscape design method, called the Seeds Scattering system (SS system), that was developed by the AnS Studio to carry out the Sony forest project in Japan.This method enables us to manage various environmental conditions in design processes, to design ‘natural’ in urban areas, ( i.e., people perceive a forest in an urbanized area as if it is natural although the forest is not genuinely natural). First, this paper discusses the limitations of the conventional method of landscape design. In Section 3 to 4, we describes the SS system together with the design process of the project. In Section 5, we present the system from a different perspective, that is, as a method for satisfying social requirements to gain human appreciation.The designer’s role in this system is not to manipulate geometries or compositions of tree groupings but to design the fundamental rules that underlie them. As a result, the designer can create a landscape in an interactive manner, thereby producing one that inherently belongs to its site.

doi	https://doi.org/10.52842/conf.acadia.2011.390
summary	This paper proposes a new interactive design method, called the networked coding method (NC method), which can manage computational design, multi-objective optimization and digital timber fabrication in an interactive design process. First, this paper discusses several drawbacks of the conventional method for architectural design. Second, the paper describes the facilities and equipment of the fabrication laboratory where the NC method was developed. Third, the paper outlines the components of the NC method together with the design process of architectural elements, called integrated fabric 2011. Finally, the paper summarizes several advantages of the method, including the production of an architectural element called the integrated-fabric that integrates various functions into one single element. The method is shown to handle any datasets, including structural and environmental analysis, which were otherwise difficult to integrate into conventional design processes.

title	Mirrored message wall: Bridging the real and virtual community
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 311-320

summary	The Mirrored Message Wall is a cross-world digital public display located in both real and virtual world, for collective sharing of thoughts and messages and serves to connect the real world and virtual communities. The wall was installed at a university library foyer and concurrently at a 3D virtual campus for user studies. This paper presents its design, social factors considered in the design, implementation, and the findings of the user survey and observations. The results confirm that such an installation does encourage people to interact with each other and the results will inform a better design for the next version.
