To Wandiligong : a visual journey through memory, time, space, light, landscape and fourteen layers of glass

This research project examines the process of conceptualisation and its effects on the development of layers of meaning in a visual context. It explores a journey over time, within an observed environment. It explores the conceptual processes which, like a physical journey, runs through many landscapes. Memory and emotion, analysis and observation, recording and interpretation and as a final destination, the practical application in the making of the pictures. This exegesis compares the differences between the theoretical stances artists have taken in the pursuit of creating work based on the depiction of the landscape. It considers a variety of approaches to image and meaning and determines the effect of disruption as it relates to art practice over centuries and to my own practice. Throughout the work there is an exploration of the different forms of disruption on the landscape, from colonisation through to the visual effects of a changing climate. Consideration is given to the similarities and differences between the practices of visual art and communication design particularly in relation to the role of the audience. The process of research and experimentation in the making of 16 digitally augmented inkjet print, photographic images and an accompanying story map drawing of the journey is described. This involved the investigation of the conceptual development processes and approaches in relation to landscape imagery and the effect of a changing climate on their visual outcomes. The results of my experimentation in capturing images through drawing and photography using graphite pencils and paper and a camera, in a car moving through the landscape, are described. This is followed by a description of my experimentation of the use of a disruptive digital drawing application on photographic images located within an iPad and how the resulting images were conceptualised and created.Masters by Researc

Image Semantics in the Description and Categorization of Journalistic Photographs

This paper reports a study on the description and categorization of images. The aim of the study was to evaluate existing indexing frameworks in the context of reportage photographs and to find out how the use of this particular image genre influences the results. The effect of different tasks on image description and categorization was also studied. Subjects performed keywording and free description tasks and the elicited terms were classified using the most extensive one of the reviewed frameworks. Differences were found in the terms used in constrained and unconstrained descriptions. Summarizing terms such as abstract concepts, themes, settings and emotions were used more frequently in keywording than in free description. Free descriptions included more terms referring to locations within the images, people and descriptive terms due to the narrative form the subjects used without prompting. The evaluated framework was found to lack some syntactic and semantic classes present in the data and modifications were suggested. According to the results of this study image categorization is based on high-level interpretive concepts, including affective and abstract themes. The results indicate that image genre influences categorization and keywording modifies and truncates natural image description

Challenges in Image Cataloging: A Case Study of the Image Database at the North Carolina Biotechnology Center

This paper reviews some challenges of image cataloging in the form of a literature review and a usability study conducted on the image database at North Carolina Biotechnology Center, hosted on Presto Inmagic software. The usability study aims to examine whether the addition of descriptive metadata detailing the conceptual aspects of images, e.g. the images' Aboutness, has a positive effect on users' searching experience while they conduct a series of assigned searching tasks designed to generate queries that require searching for images whose subject can be considered both general and abstract. In addition to this research question, the database design and existing description are examined for effectiveness

Sketching and visual perception in conceptual design : case studies of novice and expert architecture students.

This research is concerned with conceptual sketches, visual perception and verbal description. Firstly, it focuses on the role of sketching in conceptual design and begins to question why conceptual sketches are considered a good medium for reflective conversation with one's own ideas and imagery. Secondly, it focuses exclusively on the mental process involved in the analysis and verbal description of conceptual sketches. The empirical study examines how novice and expert designers might perceive different things from the same conceptual sketch and thus use different verbal descriptions, and what this might reveal about their different approaches to design. For this reason some experiments on visual perception, conceptual sketches and verbal description were conducted with expert and novice architecture students. The main objective is to verify to what extent the use of formal references such as line, square or circle and symbolic references such as describing a circle as a sun or a long oval as a sausage, help to understand how designers might think with sketches, while searching for a specific design solution. It also investigates which of the two types of images (non-architectural and architectural sketches) present greater potential for allowing the use of formal and symbolic verbal references, and why. The results show that, on average, the expert group used more formal and symbolic verbal references per minute than novices while describing the same images. The results also show that the non-architectural sketch was judged as easier to describe than the architectural one and gave rise to the use of more symbolic references. This can be seen to confirm earlier work suggesting that we fmd symbolic descriptions easier and more powerful than formal ones. The results also suggest that the expert students were more able to employ symbolic references to architectural concepts than novice students. However, in many other respects there were few differences between the groups. This may in part be due to the limitations of the empirical methodology employed

Cammp Team

The International Space Station (ISS) Configuration Analysis Modeling and Mass Properties (CAMMP) Team is presenting a demo of certain CAMMP capabilities at a Booz Allen Hamilton conference in San Antonio. The team will be showing pictures of low fidelity, simplified ISS models, but no dimensions or technical data. The presentation will include a brief description of the contract and task, description and picture of the Topology, description of Generic Ground Rules and Constraints (GGR&C), description of Stage Analysis with constraints applied, and wrap up with description of other tasks such as Special Studies, Cable Routing, etc. The models include conceptual Crew Exploration Vehicle (CEV) and Lunar Lander images and animations created for promotional purposes, which are based entirely on public domain conceptual images from public NASA web sites and publicly available magazine articles and are not based on any actual designs, measurements, or 3D models. Conceptual Mars rover and lander are completely conceptual and are not based on any NASA designs or data. The demonstration includes High Fidelity Computer Aided Design (CAD) models of ISS provided by the ISS 3D CAD Team which will be used in a visual display to demonstrate the capabilities of the Teamcenter Visualization software. The demonstration will include 3D views of the CAD models including random measurements that will be taken to demonstrate the measurement tool. A 3D PDF file will be demonstrated of the Blue Book fidelity assembly complete model with no vehicles attached. The 3D zoom and rotation will be displayed as well as random measurements from the measurement tool. The External Configuration Analysis and Tracking Tool (ExCATT) Microsoft Access Database will be demonstrated to show its capabilities to organize and track hardware on ISS. The data included will be part numbers, serial numbers, historical, current, and future locations, of external hardware components on station. It includes dates of all external ISS events and flights and the associated hardware changes for each event. The hardware location information does not always reveal the exact location of the hardware, only the general location. In some cases the location is a module or carrier, in other cases it is a WIF socket, handrail, or attach point. Only small portions of the data will be displayed for demonstration purposes

Cognitive visual tracking and camera control

Cognitive visual tracking is the process of observing and understanding the behaviour of a moving person. This paper presents an efficient solution to extract, in real-time, high-level information from an observed scene, and generate the most appropriate commands for a set of pan-tilt-zoom (PTZ) cameras in a surveillance scenario. Such a high-level feedback control loop, which is the main novelty of our work, will serve to reduce uncertainties in the observed scene and to maximize the amount of information extracted from it. It is implemented with a distributed camera system using SQL tables as virtual communication channels, and Situation Graph Trees for knowledge representation, inference and high-level camera control. A set of experiments in a surveillance scenario show the effectiveness of our approach and its potential for real applications of cognitive vision

When conventional procedures are no longer the rule for application: design as a discipline opens up to new possibilities

This paper discusses the development of the prototype application ‘LabanAssist’. It looks at the design rationale used for the creation of what is fundamentally a system for recording dance knowledge on a score, as identifiable and replicable signs and symbols. A system made necessary because the conventions of other established disciplines, such as engineering and computer science practices, were no longer considered to be effective alone, in facilitating the production of well-designed cultural artefacts (Calvert, Fox, Ryman, & Wilke, 2005; Ebenreuter, 2005). It is important to ask how can we understand design as a discipline amongst other fields of study with longstanding conventions and traditions and if the discipline of design offers effective ways of thinking about the creation and art of making products or services for the enhancement of the human experience? Is design a discipline because it adheres to existing and established rules of interdisciplinary knowledge from which it draws, or is it a discipline in its own right that as a significant field of intellectual development utilizes interdisciplinary knowledge as a basis for creativity and invention?” While there is no simple answer to these questions, the design approach adopted for the development of the prototype application ‘LabanAssist’ offers a working example in which the central theme of grammar, or more particularly the rules of a language, depart from the conventional use for its practical application. This application is one in which a literal understanding of grammar is no longer seen as an adequate basis for the generation of dance knowledge expressed via symbolic writing systems. Instead, this research focuses on the way in which the figurative aspects of language can be represented in the design of an interface to orient user thinking and facilitate the generation of diverse movement compositions.

A multimodal social semiotic analysis of lecturer pedagogy for the physics concept of angular motion in physiotherapy education

Angular motion is a foundational concept in physiotherapy, applied when measuring joint range of motion (rom) in assessment and treatment of patients. Accordingly, first-year physiotherapy students are commonly taught rom measurement skills in their applied Physiotherapy course and are introduced to the concept of angular motion in their Physics course where their learning is primarily assessed through problem-solving. However, studies of student learning of angular motion show that while students can solve problems, they do not always have the necessary conceptual understanding to use their procedures appropriately and flexibly in other disciplines. Physics education researchers also demonstrate that accessing, learning, and communicating the conceptual and procedural knowledge involves using the affordances of multimodal language. Thus, a promising line of inquiry is how lecturers use the affordances of multimodal language in pedagogy to create opportunities for students to develop both conceptual and procedural understanding. My study focuses on a lecturer's pedagogy for the concept of angular motion in a Physics course for first year physiotherapy students at a South African university. Specifically, I use a multimodal social semiotic perspective to describe what and how she uses the affordances of multimodal language − verbal talk, written text, images, symbols and symbolic equations, gestures, and objects − to give presentational, organisational and orientational meanings. I also explain her pedagogical choices in the meaning-making process. In this focused ethnographic study, I observed lecture recordings to produce data on the lecturer's pedagogy. A subsequent semi-structured interview with the lecturer was analysed to understand the lecturer's choices. The multimodal social semiotic analysis shows that the lecturer organised her pedagogy to develop both conceptual and procedural meaning, while also relating these meanings to problem-solving, and to orientate students to the relevance of angular motion in physiotherapy. This organization was informed by her comprehensive understanding of the physics content, and its relation to the Physiotherapy course and physiotherapy practice, and the experiences and resources of the students in the class. Evident in her pedagogy was a pattern of starting with a focus on conceptual meaning using verbal talk, images, and gestures, following which she integrated symbols and symbolic equations which functioned as a link to focussing on procedural meaning as applied in problem-solving. This study contributes to existing physics and physiotherapy education research, an in-depth description and explanation of a lecturer's motivated, contextualised use of multimodal language to give meaning to the physics of angular motion for physiotherapy. These learnings and the multimodal social semiotic tools by which they were produced can be put to work in education development practice with disciplinary lecturers. Specifically, they serve to make explicit the affordances of various language modes for communicating particular conceptual and procedural meanings as a relevant for physiotherapy for planning pedagogy
