ISBN: (纸本)9781424435340

The paper develops and discusses a conceptual model for a mixed reality-based remote collaborative system (MR-Collab) based on motivated learning agents. The proposed MR-Collab system is described in details as well to help better understand this model. Self-development agent based on previous work is an intelligent agent, which not only receives information from sensors in the environment, but also gives valuable suggestions that could help to improve the system. The model is not limited to this specific system, but could be adapted to other collaboration systems as well.

An Empirical Study on Augmented Virtuality Space for Tele-Inspection of Built Environments

引用

Tsinghua Science and Technology 2008年第S1期13卷 286-291页

作者： Xiangyu Wang, Rui Chen key centre of design computing and cognition, Faculty of Architecture, design and Planning, The University of Sydney, Sydney NSW 2006, Australia [a]Key Centre of Design Computing and Cognition Faculty of Architecture Design and Planning The University of Sydney Sydney NSW 2006 Australia

This paper describes an empirical study on an augmented virtuality (AV)-based system dedicated for tele-inspection of built environments. This system is regarded as a solution that allows users to experience the real remote built environment without the need of physically stepping into that actual place. Such experience is realized by using AV technology to enrich the virtual counterparts of the place with captured real images from the real space. Those integrated into the AV environment are real photos that represent key landmarks/features of the real place, live video streams of on-site crew, and 3D virtual design geome-tries. The focus of this paper is the implementation and evaluation of the AV system in its current state as compared with traditional photo-based methods. Results from this preliminary empirical study show that the AV system achieves good overall satisfaction, although it involves certain general usability issues.

Creativity is often associated with surprise, novelty, usefulness and value. These characteristics do not assist in the development of a model for intelligent systems to achieve creative behaviour, since they are characteristics that help identify when something or someone has been creative, as post-facto evaluation. Rather, models of creative behaviour for intelligent systems draw on process models such as analogical reasoning and induction, or on principles such as "make the familiar strange" or "make the strange familiar". This paper describes how a computational model of curiosity, based on cognitive models of novelty and interest, can be used to focus attention in learning agents. We show how this combination of curiosity and learning can be the core reasoning process in agent-based systems that achieve creative behaviour.

Information is becoming pervasive in the contemporary society, and is increasingly saturating the visual senses and the cognitive efforts of the lay masses. As our attention for visual impulses and cognitive effort has become more competitive, new approaches are being pursued to convey information to people in memorable and intuitive ways. With human's inherent proficiency in comprehending the physical affordances present in the real world, some researchers and designers are investigating how meaningful insights can be conveyed by way of "sculpting" data. This paper proposes a domain model to establish the concept of data sculpture as a data-based physical artifact, possessing both artistic and functional qualities, that aims to augment a nearby audience's understanding of data insights and any socially relevant issues that underlie it. This paper also proposes a model of embodiment to capture and analyze the wide and multi-layered spectrum of existing data sculptures. In this model, the introduced concepts of metaphorical distances are used as a means to measure embodiment in data sculpture. The models provide groundwork for useful design principles for effective information communication of socially relevant, data-driven insights to a large, lay audience using data sculpture.

This paper reveals the preliminary results of an experiment that studied designer and client communication and interaction during the conceptual stage of design. This study analysed the most fundamental components of the 'common language' in the designer-client relationship, including voice dialogue, visual gestures and other communication cues. The purpose of the experiment was to explore the idea of virtual environments as a viable method of communication, and to quantify the benefits of virtual environments as a design facilitator between designer and client in the conceptual design phase.

Menu interface usability has been regarded as a critical factor affecting the quality of software applications. This paper developed a method for automatically generating intelligent and dynamic menu to reflect different needs from different types of end users. The contents and structures of the menu are dynamic and adaptive to the usage context (user and task). Such implementation was based on the Cognitive Walkthrough procedure and automatic instrumentation. This paper also described a pilot study performed to evaluate the effectiveness of the dynamic menu. Preliminary results showed that the dynamic menu interface reduced the time for menu search per task significantly than the normal menu interface. The total time for completing a series of tasks was also reduced significantly.

Using augmented reality to plan virtual construction worksite

引用

International Journal of Advanced Robotic Systems 2007年第4期4卷 501-512页

作者： Wang, Xiangyu Key Centre of Design Computing and Cognition Faculty of Architecture Design and Planning University of Sydney Sydney NSW 2006 Australia

Current construction worksite layout planning heavily relies on 2D paper media where the worksite planners sketch the future layout adjacent to their real environment. This traditional approach turns out to be ineffective and prone to error because only experienced and well-trained planners are able to generate the effective layout design with paper sketch. Augmented Reality (AR), as a new user interface technology, introduces a completely new perspective for construction worksite planning. This paper disucsses the related AR work and issues in construction and describes the concept and prototype of an AR-based construction planning tool, AR Planner with virtual elements sets and tangible interface. The focus of the paper is to identify and integrate worksite planning rules into the AR planner with the purpose of intelligently preventing potential planning errors and process inefficiency, thus maximizing the overall productivity. Future work includes refining and verifying AR Planner in realistic projects.

12th International Conference on Computer-Aided Architectural design Research in Asia, CAADRIA 2007

作者： Murty, Paul Purcell, Terry Key Centre of Design Computing and Cognition University of Sydney Australia

Some designers have a knack of making design look easy, producing concepts, seemingly from nowhere. Other designers, suspicious of pie-in-the-sky ideas, prefer to design methodically. Are novel design ideas simply thoughts from out-of-the-blue, or are they insightful, resulting from deeper understanding? This paper reviews statements from a recent interview study of architects and designers, which assessed the extent to which conceptual designing is insightful. Most respondents stated that insights contributed to their designing, but two affirmed rational design processes and appeared skeptical of discovery based concepts. Analysis of the respondent statements generally, indicates that: 1) there are different levels of insightfulness, 2) insighful discoveries are also qualitatively different and 3) many appear to be an outcome of latent preparation (an incubation-like mental activity that ranges between active conscious designing and passive apparent unconscious activity), rather than arbitrary, out-of the- blue inspirations. The paper concludes by considering prospects for further research and implications for both education and digital media.

Architectural space is a key contributor to the perceptual world we experience daily. We present 'ParticleTecture', a soundspace installation system that extends spatial perception of ordinary architectural space through gestural interaction with sound in space. ParticleTecture employs a particle metaphor to produce granular synthesis soundspaces in response to video-tracking of human movement. It incorporates an adaptive mechanism that utilizes a measure of engagement to inform ongoing audio patterns in response to human activity. By identifying engaging features in its response, the system is able to predict, pre-empt and shape its evolving responses in accordance with the most engaging, compelling, interesting attributes of the active environment. An implementation of ParticleTecture for gallery installation is presented and discussed as one form of architectural space.

This paper provides information on Augmented Reality (AR) and their potential applications in heavy construction equipment operator training. Augmented Reality involves the use of special display and tracking technology that are capable of seamlessly merging digital (virtual) contents into real environments. Augmented Reality technology has been applied in many application domains outside construction (e.g., medical applications and surgeries, military training and warfare, manufacturing assembly and maintenance, design and modeling, precinct specific instant information, and various forms of entertainment) and the ever-increasing power of hardware rendering systems and tracking technology should motivate the creation of AR-based systems to benefit construction industry. This paper discusses the potentials of AR in construction equipment operation and operator training. A construction application for AR technology focused in this paper is an AR-hased real world Training System (ARTS) that trains the novice operators in a real worksite environment populated with virtual materials and instructions. This paper focuses on the conceptual design and development of mechanisms/strategies for the ARTS in the context of certain identified application scenarios. Discussion of limitations of Augmented Reality technology for construction applications include mature of technology, data resource, technology transfer, social attitude, etc., is also presented.
