Previous issue date: 2010 / Resumo: Com o desafio de projetar interfaces de usuários que contribuam com a promoção de uma cultura digital entre os cidadãos brasileiros, uma Rede Social Inclusiva (RSI) está sendo desenvolvida no âmbito do Projeto e-Cidadania2. Seu intuito é o de viabilizar o acesso ao conhecimento para maior número de pessoas, independentemente da sua familiaridade com as Tecnologias de Informação e Comunicação (TIC) ou do seu grau de letramento - entre outras habilidades. Os sistemas de apoio e as pesquisas conduzidas sobre os mesmos apresentam pouca preocupação com a questão da inclusão e acessibilidade, principalmente quando relacionados a redes sociais. Neste contexto, esta dissertação propõe um mecanismo de meta-comunicação cujo objetivo é apoiar os participantes de RSI na sua comunicação com o sistema no que diz respeito ao modelo conceitual das funcionalidades. A pesquisa foi realizada com base nos princípios do Design para Todos, utilizando-se dos artefatos da Semiótica Organizacional e de técnicas adaptadas do Design Participativo. As contribuições do trabalho incluem: a identificação de requisitos para ferramentas de comunicação e expressão buscando atenderàs necessidades dos cidadãos brasileiros, na sua maior extensão possível; a proposta de um mecanismo de meta-comunicação para redes sociais inclusivas e uma avaliação preliminar de tal mecanismo / Abstract: In order to face the challenge of designing user interfaces that contribute to the promotion of a digital culture among Brazilian citizens, an Inclusive Social Network (ISN) is being conceived in the e-Cidadania Project3. It aims at making possible for people to access knowledge, regardless of their familiarity with Information and Communication Technologies (ICT) or their literacy skill - among other abilities. The support systems and the research lead on such systems present few concerns with the question of the inclusion and accessibility, mainly when related the social nets. In this scenario, this work proposes a mechanism for meta-communication to support participants of this ISN in all communication that are related with the conceptual model of the system's functionalities. The investigation was carried out based on the principles of the Design for All, using artifacts from Organizational Semiotics and techniques that were adapted from the Participatory Design. The work contributions include: the identification of requirements for communication and expression tools aiming at the fulfillment of Brazilian citizens' needs, in the vastest extension possible; the proposal of a meta-communication mechanism for inclusive social nets; and a preliminary evaluation of the considered mechanism / Mestrado / Interação Humano-Computador / Mestre em Ciência da Computação

Utvecklingsprocessen av ett företags produktionssystem : En kvalitativ intervjustudie om hur ett medelstort företag beaktar användarcentrerad systemdesign i utvecklingsprocessen av ett nytt produktionssystemReichler, Joakim January 2013 (has links)
I denna studie har författaren undersökt hur ett medelstort företag gick tillväga vid framtagan-det av ett produktionssystem och jämfört processen med de teorier och riktlinjer som finns för användarcentrerad systemdesign. Studien har genomförts baserat på litteraturstudier och semistrukturerade intervjuer. Intervjuobjekten har utsetts tillsammans med handledaren, tillika linjechef för utvecklings-gruppen, på företaget för att redovisa olika perspektiv på utvecklingsarbetet. I resultatavsnittet presenteras utvecklingsprocessen med en modell av flödet tillsammans med en beskrivande text. Genom interna instruktioner för utveckling av datoriserade system anslu-ter företaget bl.a. till olika teorier inom användarcentrerad systemdesign. I det studerade ut-vecklingsprojektet var olika användare inledningsvis med informellt och allteftersom systemet växte så fick de vara med och göra acceptanstester och utvärderingar innan nya uppdateringar skulle släppas. Slutsatsen av studien är att flera inslag av användarcentrerad systemdesign applicerats i ut-vecklingsarbetet i företaget vilket sammantaget gör att användarnas synpunkter tagits tillvara. Dock följer företaget inte någon speciell metod inom området vilket sannolikt skulle förbättra utvecklingsprocessen i framtida projekt.

Användbarhet för e-läromedel : anpassning för olika lärstilar / Usability for e-learning applications : adapting for different learning stylesLinde, Kristina January 2014 (has links)
Vid utveckling av elektroniska läromedel är användbarhet en viktig faktor. Vad som är användbart är beroende av användarens behov och förutsättningar och läromedel har ofta en heterogen målgrupp. Målet med den här undersökningen har varit att besvara frågan hur e-läromedel kan användbarhetsanpassas för olika lärstilar. Undersökningen har genomförts med hjälp av litteraturstudier samt intervjuer med läromedelsförlag. Delar av Dunn & Dunns lärstilsmodell, specifikt sinnespreferens och informationsbearbetning, har relaterats till aktuella riktlinjer för användbarhet i e-läromedel. Undersökningen har visat att anpassningsbara läromedel gynnar användbarheten samt att studier som anpassas till individuell lärstil ger bättre resultat. Den visar också att beteende och lärstil förändras med åldern. E-läromedel kan individanpassas genom att innehålla flera olika vägar till lärandemålen och tillåta användarna att välja och strukturera sin egen lärmiljö utifrån dem. Läromedelsutvecklare behöver ta hänsyn till både teknisk användbarhet (hantera plattformen) och pedagogisk användbarhet (lära sig innehållet). Genom att införliva metoder som passar för såväl visuell, auditiv, kinestetisk och taktil sinnespreferens som för analytisk respektive holistisk informationsbearbetning kan läromedel ge ett mer heltäckande stöd för användargruppens inlärning. Samtidigt behövs balans och restriktion för att inte överbelasta användarna med inställningsmöjligheter. Gränssnittet bör vara intuitivt och konsekvent, för att inte ta fokus från innehållet, materialet bör delas upp, för att minska den kognitiva belastningen och användarna behöver känna kontroll över lärmiljön, för att stärka motivationen. Läromedelsförlagen har redan idag goda erfarenheter av att satsa på mångsidighet och lärstilsmodeller kan bidra med struktur och balans för att se till att ingen aspekt missas. / When developing electronic learning applications, usability is an important factor. What is useful depends on the user's needs and abilities. Learning applications often have a heterogeneous target group. The aim of this thesis was to answer the question of how e-learning applications can adapt usability for different learning styles. The survey was conducted by means of literature studies and interviews with educational publishers. Parts of the learning style model by Dunn & Dunn, specifically perceptual preference and information processing, have been related to the current guidelines for usability of e-learning applications. The survey has shown that customized learning applications favor usefulness and that studies tailored to individual learning style have better results. It also shows that the behaviors and learning styles change with age. E-learning applications can be individually adjusted by containing several different paths to learning outcomes and allowing users to select and structure their own learning environment. Developers of e-learning applications need to consider both the technical usability (managing the platform) and pedagogical usability (learning the content). By incorporating methods that are suitable for both visual, auditory, kinesthetic and tactile preference and for analytic and global information processing, the educational application can provide a more complete support for the user-group's learning process. Meanwhile, balance and restriction is needed in order to not overwhelm users with options. The interface should be intuitive and consistent, so as not to detract from the content. The material should be divided, in order to reduce the cognitive load. Users need to feel in control of the learning environment, to strengthen motivation. The study shows that educational publishers already have good experience from prioritizing versatility. Adapting learning style models can help with structure and balance to ensure that no aspect is overlooked. / <p>Godkännandedatum: 2014-06-24</p>

Use of informatics methods to identify problems and then design, develop and evaluate solutions to support health workers in their management of malaria...Carlo Unda, Maria Lorena January 2016 (has links)
Malaria is both a preventable and curable disease if treated early and appropriately. However, it is estimated that every 30 seconds a child dies of malaria in sub-Saharan Africa. The use of innovative eHealth/mHealth tools for malaria that seamlessly integrate into the workflow of healthcare workers could potentially ameliorate this problem. Successful design and development of these tools require an overarching understanding of the socio-technical context for the problems and opportunities in the application domain. A series of studies involving malaria management in the Millennium Village Project (MVP) cluster in rural Ghana were performed. A new method introduced by the author was applied to prioritize health information needs of stakeholders that have the potential to have a higher impact in solving health related problems. The result of applying this method was a group of impactful interventions for the MVP malaria program in Ghana. Findings from this study were validated with the MVP Ghana eHealth team, and after mutual agreement, an eHealth/mHealth intervention around malaria supply chain management was selected for further study. User-Centered Design (UCD) methods were adapted for use in a resource poor setting. Functional and non-functional requirements were identified. A low fidelity prototype was created and early usability inputs were collected. A high fidelity prototype was created to provide decision support to health workers through visualizations of stock levels and recommendations of quantities to order. Results from evaluation studies of the high fidelity prototype with end users suggest that they perceive the prototype as both easy to use and useful, with a potential for adoption and with a low risk of implementation. Usability problems found during the course of the study should be addressed to increase the potential of adoption. To obtain a more complete list of usability issues, both users’ and experts’ evaluations are recommended as well as the use of native and foreign test facilitators.

Facilitating communication for deaf individuals with mobile technologiesSummet, Valerie Henderson 31 March 2010 (has links)
Communication between deaf individuals and hearing individuals can be very difficult. For people who are born deaf, English is often a second language with the first language being American Sign Language (ASL). Very few hearing people in the United States sign or are aware of Deafness, Deaf culture, or how to appropriately communicate with people with hearing loss.
In this thesis, I concentrate on the role that mobile technologies can play in ameliorating some of these issues. In formative work with Deaf teenagers in the metro-Atlanta area, I investigate the role that communication technologies play in the lives of many Deaf individuals and examine how these devices have effected their communication patterns and social circles. Specifically, the teens identified problems communicating with hearing individuals such as close friends and family in face-to-face situations.
Having identified sign language use at home as one of the earliest interventions for Deaf children, I investigated the use of mobile phones for learning survival-level ASL. I created a prototype software application which presented short ASL lessons via either a mobile phone or desktop web-browser. The software presented the lessons via one of two different scheduling methods designed to take advantage of the spacing effect during learning. I designed and conducted a study of forty individuals with no prior ASL knowledge which compared the effects of both scheduling algorithm and platform. My results show that individuals who used a mobile phone platform and received a group of lessons at one time performed better on post-test receptive and generative ASL metrics than did participants in the three other conditions.

Exploring user interface challenges in supporting activity-based knowledge work practicesVoida, Stephen 19 May 2008 (has links)
The venerable desktop metaphor is beginning to show signs of strain in supporting modern knowledge work. Traditional desktop systems were not designed to support the sheer number of simultaneous windows, information resources, and collaborative contexts that have become commonplace in contemporary knowledge work. Even though the desktop has been slow to evolve, knowledge workers still consistently manage multiple tasks, collaborate effectively among colleagues or clients, and manipulate information most relevant to their current task by leveraging the spatial organization of their work area. The potential exists for desktop workspaces to better support these knowledge work practices by leveraging the unifying construct of activity. Semantically-meaningful activities, conceptualized as a collection of tools (applications, documents, and other resources) within a social and organizational context, offer an alternative orientation for the desktop experience that more closely corresponds to knowledge workers' objectives and goals.
In this research, I unpack some of the foundational assumptions of desktop interface design and propose an activity-centered model for organizing the desktop interface based on empirical observations of real-world knowledge work practice, theoretical understandings of cognition and activity, and my own experiences in developing two prototype systems for extending the desktop to support knowledge work. I formalize this analysis in a series of key challenges for the research and development of activity-based systems. In response to these challenges, I present the design and implementation of a third research prototype, the Giornata system, that emphasizes activity as a primary organizing principle in GUI-based interaction, information organization, and collaboration. I conclude with two evaluations of the system. First, I present findings from a longitudinal deployment of the system among a small group of representative knowledge workers; this deployment constitutes one of the first studies of how activity-based systems are adopted and appropriated in a real-world context. Second, I provide an assessment of the technologies that enable and those that pose barriers to the development of activity-based computing systems.

Development of a telerobotic test bench system for small-field-of-operation bilateral applications with 3D visual and haptic (kinaesthetic) feedbackSmit, Andre 04 1900 (has links)
Thesis (MScEng) Stellenbosch University, 2014 / ENGLISH ABSTRACT: Teleoperation as a field has seen much change since its inception in the early 1940s with Dr.
Raymond Goertz producing the first teleoperation system for manipulating radioactive
materials. With advances in core and supporting technologies, the systems have grown
in complexity and capability, allowing users to perform tasks anywhere in the world irrespective
of physical distance. The feasibility of such systems has increased as the drive for
use of telepresence robots, exploration robots as in space exploration, search and rescue
robots and military systems such as UAVs and UGVs gain popularity.
This prompted the development of a proof of concept modular, user centred telerobotic
system. The current project is the second iteration in the development process.
Teleoperation and more specifically telerobotic systems pose a challenge for many system
developers. This may be a result of complexity or the wide assortment of knowledge areas
that developers must master in order to deliver the final system. Developers have to balance
system usability, user requirements, technical design and performance requirements.
Several developmental process models are considered in context of Engineering Management
(EM). A larger Systems Engineering developmental process is used, with focus on
the primary and supportive EM components. The author used a hybrid developmental
model that is user focussed in its approach, the User-Centred Systems Design (UCSD)
methodology was adopted as the primary model for application within the two distinct
developmental categories. The first category hardware and system integration utilised the
UCSD model as is. The second - Software development - relied on the use of agile models,
rapid application development (RAD) and extreme programming (XP) were discussed
with XP being chosen as it could easily incorporate UCSD principles in its development
process.
Hardware systems development consisted of mechanical design of end-effectors, configuration
management and design, as well as haptic and visual feedback systems design for
the overall physical system. Also included is the physical interface design of the input
(master) cell. Further software development was broken into, three sections, the first and
most important was the graphical user interface, haptic control system with kinematic
model and video feedback control.
The force following and matching characteristics of the system were tested and were found
to show an improvement over the previous implementation. The force magnitude error
at steady state was reduced by 10%. While there was a dramatic improvement in system
response, the rise time was reduced by a factor 10. The system did however show a decrease
in angular accuracy, which was attributed to control system limitations.
Further human-factor analysis experiments were conducted to test the system in two typical
use-case scenarios. The first was a planar experiment and the second a 3D placement
task. The factors of interest identified were field-of-view, feedback vision mode, and input
modality. Heuristic performance indicators such as time-to-completion and number of collisions
for a given task were measured. System performance was only showed significant
improvement when used with haptic control. This shows that the research into haptic
control systems will prove to be valuable in producing usable systems. The vision factor
analysis failed to yield significant results, although they were useful in the qualitative
systems analysis.
The feedback from post-experimentation questionnaires showed that users prefer the Point
of View as a field of view and 2D viewing over 3D viewing, while the haptic input modality
was preferred.
The results from the technical verification process can be used in conjunction with insights
gained from user preference and human-factor analysis to provide guidance for future
telerobotic systems development at Stellenbosch University. / AFRIKAANSE OPSOMMING: Telewerksverigting as ’n gebied het al vele veranderinge ondergaan vandat die eerste stelsels
deur Dr. Raymond Goertz geimplementeer was in die vroeë 1940s vir die hantering
van radioaktiewe materiale. Met vordering in kern en ondersteunende tegnologieë, het
die telewerksverigtingstelsels toegeneem in kompleksiteit asook gevorder in vermoeënsvaardigheid,
wat gebruikers in staat stel om take te verrig vanuit enige plek op aarde,
ongeag die fisiese afstand wat die gebruiker en die werksarea skei. Die lewensvatbaarheid
van hierdie stelsels het ook toegeneem weens die belangstelling in teleteenwoordigheidrobotte,
ruimtevaardige-robotte, reddings-robotte en militêre-robotte soos onbemandelug-
voertuie (OLV) en onbemande-grond-voertuie(OGV).
As gevolg van die belangstelling in telerobotiese stelsels is die ontwikkeling van ’n modulêre,
gebruikers-gesentreerde telewerksverigting stelsel onderneem. Die huidige projek is
’n tweede iterasie hiervan.
Telewerksverigting, en meer spesifiek, telerobotika stelsels ontwikelling, vereis dat stelselontwikkelaars
’n verskeidenheid kennisareas bemeester. Die ontwikkelaar moet ’n belans
vind tussen gebruiker vereistes, bruikbaarheid asook tegniese ontwerp en prestasie vereistes.
Menigde ontwikkelingsproses modelle is oorweeg en behandel in die konteks van
Ingenieursbestuur (IB). ’n Stelselsontwikkeling proses is gevolg met ’n fokus op primêre
en ondersteunende IB komponente. ’n Gemengde ontwikkeling is toegepass tot die projek
wat die gebruiker as ’n hoof komponent van die stelsel in ag neem. Die oorhoofse ontwikkelingsmodel
is die User-centred Systems Design (UCSD) proses, wat vir beide hardeware
en sagteware ontwikkeling gebruik is.
Vir die hardeware ontwikkeling is die UCSD toegepas soos dit uiteengesit is in die literatuur.
Die sagteware ontwikkeling is voltooi met behulp van ratse metodes, “Rapid
Application Development” RAD en “Extreme Programming” (XP) was oorweeg en XP was gekies as ontwikkelingsmodel. XP was die natuurlike keuse weens die gemak waarmee
UCSD metodes en prinsiepe kon geinkorporeer word in die ontwikkelings proses.
Hardeware onwikkeling het bestaan uit meganiese ontwerp, manipulasiegereedskap ontwerp,
konfigurasie bestuur en ontwikkeling asook haptiese en visueleterugvoer stelselsontwerp
van die fisiese stelsel insluitend die fisiese koppelvlakontwerp van die meester sel.
Verder is sagtewareontwerp opgedeel in ’n haptiesebeheerstel met ’n kinematiese model
ontwikkeling, videoterugvoerbeheer en gebruikersintervlak ontwerp.
Die vermoëe van die stelsel om krag insette na te boots was verbeter met ’n gestadigde
verbetering van 10%. Die reaksietyd van die stelsel is verbeter met ’n faktor van 10. Die
stelsel het ’n verswakking getoon in die algehele hoekakkuraatheid, die oorsprong van die
verswakking kan aan die beheerstelsel teogeken word.
Verdere menslikefaktoranalise eksperimente is voltooi om die stelsel in twee tipiese gebruikgeval
scenario’s te toets. Die eerste, ’n platvlak-eksperiment en die tweede ’n 3D plasingingstaak
eksperiment. Die faktore van belang is ïdentifiseer as, visie-veld, terugvoervisie
modus en insette modaliteit. Heuristiese prestasie-aanwysers soos tyd-tot-voltooiing en
die aantal botsings vir ’n gegewe taak is gemeet. Stelselprestasie het slegs aansienlike
verbetering getoon wanneer die stelsel met die haptiesebeheer modus bedryf word. Die
visiefaktor ontleding het geen noemenswaardige resultate opgelewer nie.
Terugvoervorms was na elke eksperiment voltooi. Vraelyste het getoon dat gebruikers
die oogpunt van ’n lae hoek en 2D video oor 3D video verkies, terwyl die haptic beheer
modaliteit verkies word.
