Installation art and memory : a practice-as-research exploration

Barber, James January 2012 (has links)
This practice-as-research project investigates how a piece of site-responsive Installation Art, titled Triple Point Dunnage (exhibited in Royal William Yard, June 2009), can be used to generate knowledge about memory work through experience of site. Working in dialogue with the ideas of Daniel C. Dennett, Lucy Lippard and Gaston Bachelard, I attempted to create a permeable and fluctuating creative setting for the memory work of participants. An approach that used site as a stimulant within a process which also incorporated theoretical themes. During the period of design and construction, I interacted with and recorded interviews with people who had a personal connection with the site or with an interest in how memory works. The final installation presented layers of spoken fragmented content in a dialectic relationship within the installation’s spatial construction. The responses of the installation’s visitors and participants were collated through a response book and interviews. These were analysed in order to discover to what extent, if at all, the properties I had developed and designed into the work had shaped the engagements of the participants. The multi-valented properties of the work generated an array of responses that suggested that the viewers had fashioned their experience by blending the fragmented stories of others with their own personal histories. This engagement resembles Dennett’s concept of “self-narrator” and resonates with Bachelard’s concept of the fusion of physical and psychological space and Lippard’s understanding of place. By exploring memory through site Triple Point Dunnage generated a sense of place that was a fusion of the participants’ responses to the external physical environment and their associative memories stimulated by the affective fragmented properties of the work.

Interactive concept acquisition for embodied artificial agents

de Greeff, Joachim January 2013 (has links)
An important capacity that is still lacking in intelligent systems such as robots, is the ability to use concepts in a human-like manner. Indeed, the use of concepts has been recognised as being fundamental to a wide range of cognitive skills, including classification, reasoning and memory. Intricately intertwined with language, concepts are at the core of human cognition; but despite a large body or research, their functioning is as of yet not well understood. Nevertheless it remains clear that if intelligent systems are to achieve a level of cognition comparable to humans, they will have to posses the ability to deal with the fundamental role that concepts play in cognition. A promising manner in which conceptual knowledge can be acquired by an intelligent system is through ongoing, incremental development. In this view, a system is situated in the world and gradually acquires skills and knowledge through interaction with its social and physical environment. Important in this regard is the notion that cognition is embodied. As such, both the physical body and the environment shape the manner in which cognition, including the learning and use of concepts, operates. Through active partaking in the interaction, an intelligent system might influence its learning experience as to be more effective. This work presents experiments which illustrate how these notions of interaction and embodiment can influence the learning process of artificial systems. It shows how an artificial agent can benefit from interactive learning. Rather than passively absorbing knowledge, the system actively partakes in its learning experience, yielding improved learning. Next, the influence of embodiment on perception is further explored in a case study concerning colour perception, which results in an alternative explanation for the question of why human colour experience is very similar amongst individuals despite physiological differences. Finally experiments, in which an artificial agent is embodied in a novel robot that is tailored for human-robot interaction, illustrate how active strategies are also beneficial in an HRI setting in which the robot learns from a human teacher.

A conceptual design of a Software Base Management System for the Computer Aided Prototyping System

Galik, Daniel 12 1900 (has links)
Approved for public release; distribution is unlimited / This thesis builds upon work previously done in the development of the Computer Aided Prototyping System (CAPS) and the Prototype System Description Language (PSDL), and presents a conceptual design for the Software Base Management System (SBMS) component of CAPS. The SBMS is the most critical component of CAPS as it will coordinate the retrieval and integration of Ada software modules. A robust SBMS that enables a software system designer to successfully retrieve reusable Ada components will expedite the prototype development process and enhance designer productivity. Implementation of the conceptual design will be the basis for further work in this area.

SoundCubes prototyp : Tillhandahålla ny stimulerande hörselträning för personer med hörselnedsättningar / SoundCubes prototype : Providing new stimulating auditory training for people with hearing impairments

Mattei, Pietro, Stolica, Stefan January 2016 (has links)
Målet med projektet är att skapa en fungerande hörseltränings prototyp som kan vara användbar för en vidareutveckling av träningssystem för personer med nedsatt hörsel. Idén bygger på “The Music Puzzle” (Hansen et al. 2012). Prototypen benämndes SoundCubes och består av tre kuber med olika motiv (Fiducial markörer) på fyra av de sex sidorna. Ett ljudspår delades i tre delar och tilldelades till kuberna. Varje del fragmenterades i fyra nivåer där den första spelar upp ett instrument ända fram till att alla instrumenten hörs. Dessa faser tilldelades till Fiducial markörerna på kubens fyra sidor. Kuberna är slumpmässigt placerade horisontellt framför en kamera som är ansluten till en dator. Alla fyra sidor av kuberna som har motivet fastsatt kommer att spela upp reproduktionen av ett fragment från ljudspåret när de ställs inför kamerans synfält. Endast en specifik kombination av sidorna och horisontell ordning av kuberna kommer att leda till de fullständiga ljudspårskomponenterna och till ett applådljud som signalerar den framgångsrika reproduktionen av det ursprungliga ljudspåret. SoundCubes prototypen utvecklades funktionellt genom TUIO, ReacTIVision och Pure Data. För att kunna fastställa ifall prototypens interaktion fungerade så testades SoundCubes på 15 friska personer utan nedsatt hörsel. Testpersonerna introducerades individuellt till prototypen, och de fick sedan lyssna på det kompletta ljudspåret. Därefter fick de uppgiften att reproducera det kompletta ljudspåret genom att hitta kubernas rätta sidor och horisontella ordning. Av totalt 15 individer klarade 12 av testet inom tidsgränsen (tio minuter). Vi kunde därför komma fram till att prototypen och dess interaktion fungerar, vi kunde även observera att användningen av SoundCubes upplevdes som underhållande och engagerande. Detta första test kan därför lägga grund för vidareutveckling av SoundCubes konceptet för hörselträning på ett interaktivt och underhållande sätt. / The aim of the present project was to create a functional sound-training prototype which may be useful for further development of training systems for individuals with impaired hearing. The idea is based on the concept of “The Music Puzzle” (Hansen et al. 2012). The prototype proposed here was termed SoundCubes and it is composed of three cubes with different motives (Fiducial markers) on four of the six sides. A soundtrack was divided into three parts and was assigned to the cubes. Each part was fragmented into four parties where the first playing an instrument until all the instruments could be heard. These parts were assigned to Fiducial markers on the four sides of the cube. The cubes are randomly placed horizontally in front of a camera attached to a computer. All of the four sides with a motive of the cubes will induce the reproduction of fragments of a soundtrack when exposed to the field of the camera thanks to the specific motives attached on it. Only one specific combination of the sides and horizontal order of the cubes will lead to the complete soundtrack instrumental components and to a clapping sound which signals the successful reproduction of the2initial soundtrack. The SoundCubes prototype was developed functionally through Tuio, ReacTIVision and Pure Data. SoundCubes was tested on 15 healthy individuals without hearing impairments to determine if the prototype’s interaction works. The test individuals were individually introduced to SoundCubes, and they were allowed to hear the complete soundtrack. Thereafter, they were given the task of reproducing the complete track by finding the right side and horizontal order of the cubes. Out of a total of 15 individuals, 12 completed the test successfully within the maximum given time frame (ten minutes).We could therefore conclude that the system works properly, and we also observed that the test was experienced as very entertaining and engaging. this first test puts therefore the basis for further development of the SoundCubes concept to train people’s hearing in an interactive and entertaining way.Kjetil

Omkonstruktion av justerskruv i expanderbar duschstång / Redesign of adjustable screw in expandable shower rod

Ryttman, Tobias, Tillaéus, Nathalie January 2019 (has links)
Detta examensarbete inom integrerad produktutveckling utfördes vid Högskolan i Skövde i samarbete med Ericsindustrier i Töreboda. Rapporten beskriver metodiken samt processen som utförts i projektet för att uppnå samtliga målsättningar. Syftet bestämdes till en omkonstruktion av en justerskruv placerad i en expanderbar duschstång. Denna duschstång anses vara en viktig del av Ericsindustriers produktsortiment. Grunden till behovet av en omkonstruktion ansågs vara antalet komponenter samt komponenternas montering. Detta krävde att komponentantalet minimerades genom DFx-principer där samma material eftersträvades genom produkten. Försämrad kvalité och hållfasthet definierades som kritiska områden då Ericsindustrier önskade att upprätthålla likvärdig kundnöjdhet samt att produkten skulle hålla för minst 200 N efter omkonstruktionen. Projektets struktur följde en femstegsmodell där designprocessen inleddes med en förstudie. Fokus låg på informationsinsamling, observationer samt kartläggning av nuläget. Genereringsfasen genomsyrades av metodik för att utforska lösningsrymden. Detta innefattade bland annat brainstorming, morfologisk matris samt skissning. I projektet har prototyper haft en stor inverkan då de har fungerat både som generering samt utvärdering av lösningar. De har även agerat som kommunikation till företag samt användare genom hela processen. Iterationer har präglat hela processen för att uppnå en produktutveckling. För att upprätthålla en användarcentrerad design innefattade projektet flertalet användartester. Fötterna till duschstången samt de två rören som bildar själva duschstången identifierades till separata problem. Dessa problem har diskuterats med företaget. Konceptval utfördes efter önskemål från företaget, tester, DFxprinciper samt diskussioner tills det mynnade ut i ett slutgiltigt koncept. Detta koncept uppfyllde de utsatta kraven samt behoven. Konceptet ansågs vara en prisvärd, högkvalitativ samt miljövänlig produkt. / This bachelor degree project in integrated product development was carried out at the University of Skövde in collaboration with Ericsindustrier in Töreboda. The report describes the methodology and the process that has been carried out in the project to achieve all the stated objectives. The scope was determined to be a redesign of an adjusting screw placed in an expandable shower rod. The shower rod is considered an important part of Ericsindustrier's product range. The reason for the need of a reconstruction was the number of components and the components assembly. The component number was required to be minimized by using DFx principles where the same material was sought throughout the product. Decreased quality and lower durability were defined as critical areas since Ericsindustrier wanted to maintain customer satisfaction and the product must hold for at least 200 N after the redesign. A five-stage model formed the basis of the project structure where the design process began with a preliminary study. The focus was on information gathering, observations and mapping of the current situation. The generation phase was imbued with methodology to explore solution space. This included, among other things, brainstorming, morphological matrix and sketching. In the project, prototypes had a great impact as they functioned as both generation and evaluation of solutions. They have also acted as communication with companies and users throughout the process. Iterations have characterized the whole process to achieve a product development. In order to maintain a user-centred design, the project included several user tests. The feet of the shower rod and the two pipes that form the shower rod itself were identified as separate problems. These issues have been discussed with the company. Concept selection was carried out according to the wishes of the company, tests, DFx principles and discussions until it ended in a final concept. This concept met the required requirements and needs. Therefore, it was an affordable, high quality and environmentally friendly product.

Desenvolvimento e fabricação de uma mini-impressora 3D para cerâmicas / Development and manufacturing of mini 3D printer machine for ceramics

Garcia, Luis Hilário Tobler 14 January 2011 (has links)
O trabalho trata do estudo do processo de impressão tridimensional e desenvolvimento de uma impressora para a produção de corpos-de-prova cerâmicos. A técnica de impressão tridimensional pertence ao grupo de prototipagem rápida e consiste na obtenção de um corpo sólido a partir de um modelo digital de três dimensões, através do fatiamento do modelo tridimensional e da impressão seqüencial de suas respectivas fatias. Durante o processo de impressão, deposita-se um ligante sobre camadas sucessivas de pó e em cada camada, o ligante consolida o pó no formato bidimensional da fatia, que por fim soma-se as outras fatias subseqüentes, consolidando assim o formato tridimensional do modelo. Os equipamentos convencionais de impressão 3D utilizam pós a base de gesso e acrílico, onde o ligante, a base de água, fornece a primeira adesão química; posteriormente é infiltrada uma resina para fornecer uma ligação com o pó de acrílico. Na impressão de cerâmica a base de alumina ou zircônia, o desenvolvimento de ligantes tem de ser realizado visando à adesão química e orgânica combinadas antes da sinterização. Neste projeto, uma mini impressora 3D para corpos de prova foi desenvolvida e com ela foram produzidos corpos de geometria simples e seção constante, cujo projeto, custo, manutenção simplificada e econômica possibilita também o emprego de materiais agressivos nos ligantes, com risco de danificação de componentes, a exemplo de ácido fosfórico, porém com baixo custo de recuperação. Foram analisados diversos tipos pelo dimensionamento de seus aglomerados, fluidez e densidade. Obteve-se pó a base de gesso por R$15,00 o kilograma. Corpos de prova foram analisados com relação à resistência mecânica por flexão de três pontos, densidade, porosidade aparente e imagens por microscopia ótica e microscopia eletrônica de varredura (MEV). Um protótipo de uma mini-impressora foi idealizado, projetado e fabricado, soluções originais e econômicas foram propostas e na sua validação alguns conceitos necessitam de melhorias, ainda assim foram obtidos resultados promissores. Foi desenvolvida uma formulação de pó baseado em gesso que teve o custo de aproximadamente 5% do produto importado. / The work studies the three-dimensional printing process and the development of a 3D printer to produce ceramic specimen. The 3D printing technique belongs to the rapid prototype group and consists in obtaining a solid body from a three-dimensions digital model, through the slicing of the three-dimensional model and the sequential printing of their respective slices. During the printing process, a binder is deposited upon successive powder layers, and in each layer, the binder consolidates the powder into the bi-dimensional shape of the slice, which ultimately adds to the other slices that followed, consolidating the three-dimensional shape model. The conventional 3D printing equipments uses powder based in gypsum and acrylic, where the water-based binder, provides the first chemical bind; subsequently is infiltrated a resin to provide a binding with the acrylic powder. In the ceramic printing based on alumina or zirconia, the development of binders must be accomplished looking for a organic and chemical bind before sintering. In this project, a mini 3D printer for ceramic specimens was developed and built, with it were be produced bodies of simple geometry and constant section, which design, cost and simplified maintenance and cost also enable the use of aggressive materials in binders, with the risk of components damage, such as phosphoric acid, but with low cost to recovery. Were analyzed several types of powders by the sizing of its clusters, fluidity and density. Were obtained gypsum powder for $ 7.00 a kilogram. The specimen were analyzed in relation to the mechanical strength by three-point bending, density, apparent porosity and images by optical microscopy and scanning electron microscopy (SEM). A prototype of a mini 3D printer was designed, engineered and manufactured, unique and economical solutions have been proposed and in its validation some concepts need of improvement, yet promising results were obtained. It was developed a powder formulation based on gypsum that has cost about 5% of the imported product.

Adequação da tecnologia de modelagem tridimensional física computadorizada na obtenção de modelos de aparência voltados para o ensino de projeto em design de produto / Adequacy of computer-aided technology of physical three-dimensional modeling to produce mock-ups used in the teaching of design methodology in product design

Otero Neto, José Leonardo 12 July 2017 (has links)
A disponibilização de uma tecnologia de desenvolvimento recente, denominada neste trabalho de \"tecnologia de modelagem tridimensional física computadorizada\", ofereceu novos recursos para a obtenção de representações utilizadas no processo de desenvolvimento de projetos de produtos (modelos), que anteriormente era realizado utilizando-se exclusivamente procedimentos manuais de caráter artesanal. No entanto, existe uma diversidade de processos e de equipamentos que a utilizam, variando entre alguns simples e baratos, que podem obter objetos com algumas restrições, como de geometria, acabamento e resistência, e outros, extremamente complexos, que podem fornecer objetos com características excepcionais. Por outro lado, são utilizados diversos tipos de modelos ao longo do processo de projeto: alguns muito simples, empregados nas fases iniciais, e outros de maior complexidade, que representam o produto nas fases finais de seu desenvolvimento, entre os quais se encontra o modelo de aparência, que apresenta grande potencial de se beneficiar, em seu processo de confecção, das características particulares da referida tecnologia. O presente trabalho tem, portanto, o objetivo de apresentar um quadro detalhado da disponibilidade da tecnologia de modelagem tridimensional física computadorizada, particularmente no contexto brasileiro, a partir de pesquisa realizada com fabricantes, representantes comerciais, institutos de pesquisa e escolas de design, e de descrever as características formais e construtivas do modelo de aparência a partir de pesquisa bibliográfica e observações, de forma a identificar processos, equipamentos e procedimentos que podem ser adequados para atender à demanda por esse tipo de modelo em disciplinas de projeto de produto em escolas de design. / The availability of a new development technology, which in this text is referred to as \"computer-aided technology of physical three-dimensional modeling\", provides new resources for making representations used in product design development process (models), which previously, was almost exclusively completed through manual procedures. However, there are various types of processes and equipment that that technology which range from simple and inexpensive, that can obtain objects with some restrictions, such as geometry, finishing and resistance, and others that are extremely complex, that can provide objects with exceptional features. On the other hand, several types of models are used throughout the design process: some very simple, utilized in the early stages, and others of greater complexity, which represents the product in the final stages of its development, such as the mock-ups that have the greatest potential to benefit from the special characteristics of the technology previously mentioned. The objective of this research is to present a detailed picture of what is available for computerized three-dimensional modeling technology focused within the context of Brazil, based on research carried out with manufacturers, commercial representatives, institutes, research and design schools and describe the formal and constructive characteristics of the mock-ups, based on bibliographic research and observations, in order to identify processes, equipment and procedures that may be appropriate to meet the demand for this type of model in design schools.

Avaliação dos dispositivos destinados ao uso de sustentação e movimentação de membros superiores e proposta da melhoria do projeto baseada na integração QFD e análise funcional / The evaluation of devices intended to the supporting or movement use of the upper extremity and the proposal of improvement of project based on QFD interaction and Functional Analysis

Souza, Alessandra Cavalcanti de Albuquerque e 04 February 2016 (has links)
Esse trabalho apresenta um estudo sistemático de projeto baseado na integração da matriz da qualidade (QFD), com técnicas de análise funcional, com o objetivo de propor melhorias no projeto de dispositivos de sustentação e movimentação de membros superiores (sling), utilizados por terapeutas junto à pessoas com disfunção neuromuscular ou musculoesquelética decorrente de patologias que afetem a musculatura do ombro. Como objetivo complementar, foi feito um levantamento e análise comparativa das soluções técnicas propostas em bases de dados acadêmicas e de patentes, bem como soluções comerciais. Nas últimas décadas, um conjunto de fatores tem conduzido a demandas crescentes com relação à atuação das áreas de pesquisa e tecnologia, que possam fornecer soluções tecnicamente viáveis dentro das restrições de cada problema. A tecnologia assistiva, um campo interdisciplinar, que trata do desenvolvimento de equipamentos, desenhando fronteiras com questões de acessibilidade, com uso e adequação de produtos, atuando nas áreas de recuperação e reabilitação promovendo qualidade de vida e inclusão social de pessoas com algum tipo de deficiência ou mobilidade reduzida, apresenta uma lacuna no desenvolvimento e disponibilização de soluções. Nesse trabalho, o uso de ferramentas de metodologia de projeto, durante o projeto conceitual e em discussões do projeto informacional, permitiu uma melhor interface entre decisões técnicas de engenharia e os requisitos do usuário. O usuário intermediário, previamente definido, foram terapeutas ocupacionais, que prescrevem e acompanham o uso dos mecanismos e equipamentos junto aos usuários finais (pessoas com deficiência). Os resultados obtidos nesse trabalho indicam que o uso de ferramentas de metodologia de projeto foi significativamente relevante, principalmente na fase do projeto informacional, permitindo a inserção das experiências dos profissionais da área de saúde no desenvolvimento do conceito que incorporou grau de inovação às soluções do sling. O uso da manufatura aditiva para visualização do conceito, bem como o desenvolvimento do protótipo funcional foram importantes, para criar um processo interativo e iterativo de melhorias durante o projeto de natureza multidisciplinar. Essas melhorias incluíram adequação a diferentes tipos de mobiliários e ambientes, incluindo o hospitalar, uso unilateral ou bilateral e sistema de deslizamento para movimento do braço no plano horizontal. / This paper presents a project of systematic study based on the integration of quality matrix (QFD), practical analysis techniques; with aim to propose improvements in device design support and movement of the upper limbs (sling), used by the therapist in individuals with neuromuscular dysfunction or resulting from musculoskeletal disorders affecting the shoulder musculature. To supplement, it was made a survey and comparative analysis of the technical solutions proposed in academic databases and patents, as well as business solutions. In recent decades, a number of factors have led to growing demands with regards to performance of the areas of research and technology, which can provide technical viable solutions within the constraints of each problem. The assistive technology, an interdisciplinary field that deals with the development of equipment, draws borders with accessibility issues, using and adapting products working in the areas of recovery and rehabilitation promoting quality of life and social inclusion of people with disability or reduced mobility, it presents a gap in the development and supply of solutions. In this work, the use of design methodology tools for the conceptual design and the informational project discussions enables a better interface between technical engineering decisions and user requirements. The intermediate user, previously set was occupational therapists, prescribes and monitors the use of the mechanisms and / or equipment to end users (people with disabilities). The results of this study indicate that the use of design methodology tools is significantly relevant, especially at the stage of informational design, allowing the insertion of health professionals experience in developing the concept that incorporated degree of innovation to sling solutions. These improvements include suitability for different types of securities and environments, including hospital, unilateral or bilateral use, and sliding arm system for movement in the horizontal plane. The use of additive manufacturing concept for the display, as well as the development of functional prototype are important to create an interactive and iterative process improvements during the project, a multidisciplinary nature.
