title	Redefining Mixed Reality: User-Reality-Virtuality and Virtual Heritage Perspectives
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 2, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 675-684

summary	The primary objective of this paper is to present a redefinition of Mixed Reality from a perspective emphasizing the relationship between users, virtuality and reality as a fundamental component. The redefinition is motivated by three primary reasons. Firstly, current literature in which Augmented Reality is the focus appears to approach Augmented Reality as an alternative to Mixed Reality. Secondly, Mixed Reality is often considered to encompass Augmented Reality and Virtual Reality rather than specifying it as a segment along the reality-virtuality continuum. Thirdly, most common definitions of Augmented Reality (AR), Augmented Virtuality (AV), Virtual Reality (VR) and Mixed Reality (MxR) in current literature are based on outdated display technologies, and a relationship between virtuality and reality, neglecting the importance of the users necessarily complicit sense of immersion from the relationship. The focus of existing definitions is thus currently technological, rather than experiential. We resolve this by redefining the continuum and MxR, taking into consideration the experiential symbiotic relationship and interaction between users, reality, and current immersive reality technologies. In addition, the paper will suggest some high-level overview of the redefinition's contextual applicability to the Virtual Heritage (VH) domain.

title	Interaction, Agency and Artefacts
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 249-258
summary	This paper argues (i) that understanding of a place (especially in heritage environments) requires a level of cultural engagement and (ii) that virtual environments, in their typical current form, fail to provide such engagement. A proposed solution to the issue of cultural presence is to apply the interactive mechanisms commonly used in computer games (social agents, levels of interaction constraint, and task-based manipulation of artefacts) to virtual heritage environments. The hypothesis is that the resulting environment will allow for greater engagement and a more culturally immersive learning environment. Virtual environments also often lack techniques for evaluating the extent to which their design goals are achieved. A proposed secondary outcome is that designers and researchers of virtual environment can also use the above interactive mechanisms for the evaluation of user engagement without simultaneously interrupting the user’s feeling of engagement.

title	Where is this place?
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 85-95
doi	https://doi.org/10.52842/conf.acadia.2002.085
summary	‘Place’ is arguably an essential component of most successful virtual environments, yet the concept ofwhat is ‘place’, and what sort of ‘placeness’ is required for digital environments, are seldom discussed.A reflexive argument such as here is a place because it was designed to be a place does not stimulatedesign guidelines for virtual places, and it certainly does not help us create and evaluate virtual placessuitable for audiences who vary in intention or in available technology. To articulate useful distinctionsbetween virtual places, this paper extends design guidelines proposed by Kalay and Marx, reshapesthem with the help of Relph’s definitions, into spatial visualisation and activity-based environments, andadds a further category, the hermeneutic. The paper also proposes a graduated matrix for selection ofplacemaking elements and for selecting a mode of representation appropriate to the design objective ofthe virtual environment, be it spatial, activity-based, or hermeneutic.

title	Indirect biofed architecture: Strategies to best utilise biofeedback tools and interaction metaphors within digital architectural environment
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. 241-250
doi	https://doi.org/10.52842/conf.caadria.2011.241
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	Lazy Panorama Monopoly Table: Take Your City for a Spin
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 662-669

summary	While conventional information displays are still effective, a lack of integration between descriptive and contextual information means they cannot be used independently of additional external information. New digital systems such as Google Maps are increasing in popularity. Unfortunately these present some limitations in terms of understanding both route and survey information, and in particular navigation and orientation, such as intuitively understanding a plan view no matter which way one is facing, so visitors can quickly and intuitively learn how to get to specific buildings or to specific facilities. Digital systems may also alienate older and non computer literate users; and they display contextual information inside an interface which limits the possible range of interaction methods offered by physical interaction. Our solution was to create a 3D physical model that one could spin, which would in turn display digital panoramas that spun in rotational alignment with the physical city model. Further, the user could place category tokens in intersections of the city model, which would bring up digital panoramas on the screen and highlight facilities linked to the category chosen. Rotating the token would also rotate the digital panorama.

title	Biofeedback and Virtual Environments
source	International Journal of Architectural Computing vol. 9 - no. 4, 377-395
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, based on the biofeedback of the player. The aim was to determine which augmented effects aided or discouraged engagement in the game. Conversely, biofeedback can help calm down rather than stress participants, and attune them to different ways of interacting within a virtual environment. Other advantages of indirect biofeedback might include increased personalization, thematic object creation, atmospheric augmentation, filtering of information, and tracking of participants’ understanding and engagement. Such features may help designers create more intuitive virtual environments with more thematically appropriate interaction while reducing cognitive loading on the participants. Another benefit would be more engaged clients with a better understanding of the richness and complexity of a digital environment.

title	CAADRIA 2009 - Between Man and Machine
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, 795p.
doi	https://doi.org/10.52842/conf.caadria.2009
summary	Digital designing takes place through processes of interaction between human designers and computers. As such, its location is the in-between, a shared realm of conversation where capabilities of both man and machine are amplified. CAADRIA 2009 addresses this conversation in terms of three perspectives that drive both research and practice in the computer-aided architectural design field: Digital design as integrating, intuitive and intelligent. CAADRIA 2009 aimed to provide a forum in which ideas pertaining to these notions can be explored, discussed and developed. l Digital design is integrative. With the diverse and fast speed of the global economy in the 21st century, the barrier between different disciplines is being overcome digitally. The integration of multiple disciplines is crucial for facing the next wave of global challenges. l Digital Design is intuitive. With advanced computational technology, how humans will cooperate with machines after the computing era will surely become the next challenge for all computational design-related researchers. Intuitive interaction or computing design is the second theme addressed in CAADRIA 2009. l Digital Design is Intelligent. With artificial intelligence, design intelligence is the third theme we would like to address this year. We wish to challenge global researchers to provide a smart and responsive environment for improving our lives and stimulating our economy in innovative ways.

title	The Scholarly Rewards and Tragic Irony of 3D Models in Virtual Heritage Discourse
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 2, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 695-704
doi	https://doi.org/10.52842/conf.caadria.2019.2.695
summary	To validate the hypothesis that virtual heritage papers are reliant on providing scholarly argumentation based on 3D models, and convenient access is provided to these models where relevant, this study reviewed 264 articles from the last three available proceedings of major digital heritage events and conferences (14 in total). The findings revealed this was not the case, few contain references to accessible 3D models. We discuss why this may be so, and we outline recommendations for ensuring that virtual heritage 3D models can be preserved and accessed.
