Biometric systems have become increasingly popular for user authentication andidentification across various domains, including smartphones, laptops, financial services,healthcare, and security. These systems offer enhanced security and quickaccess to data, aiming to address the challenges associated with passwords and pins.However, achieving a method that provides a 100% guarantee in all fields and for alldevices remains a challenge. To explore user perceptions on the acceptance of biometricsystems, an online survey was conducted with 99 participants from diversebackgrounds, education levels, ages, and countries. The survey focused on understandingusers’ acceptance of biometric systems based on their experiences and perspectives.Additionally, it aimed to investigate whether demographic factors, suchas age, education, and background, influence user acceptance. The study also comparedthe preferred authentication technique among users with findings from previousstudies. The survey results supported previous research, showing that fingerprinttechnology is the most recommended and preferred method for user authentication,followed by facial recognition. This study sheds light on the growing adoption ofbiometric systems to overcome password-related issues and provides valuable insightsinto user preferences for authentication and identification methods.

Användbarhet är ett centralt begrepp i webbutveckling vid utvecklandet avtillgängliga och användbara webbsidor. Användbarhet strävar efter effektivitet ochtillfredställelse. Webbsidans användare ska kunna utföra ärende utan ansträngningeller större tidsåtgång för att slutligen känna en tillfredställelse med sig själv ochdet framgångsrikt utförda ärendet.I detta examensarbete kommer användbarhet på world wide web behandlas ur tvåinfallsvinklar, experters uppfattning respektive vardaglig användares uppfattning påbegreppet. Arbetet ämnar lyfta fram tolkningar för begreppet användbarhet och hurstort värde det har vid webbutveckling, i synnerhet en global navigations värde somverktyg för orientering på en webbsida.Frågeställningen besvaras genom en analys och likhetsgranskning först mellanmålgrupperna, sedan mot tidigare studier i sektion 5.Examensarbetet kommer främst baseras på en tidigare studie som även denifrågasätter riktlinjer för användbarhet i en intervjustudie med utvecklare inomwebbutveckling.Genom intervjuer kommer vardagliga användare och experters tolkningar jämförasmot tidigare studier och forskning för att betona det värde som användbarhet harför en välutvecklad och funktionellt framgångsrik webbsida med fokus på globalnavigation. Resultatet av undersökningen ämnar styrka eller sänka hypotesen omatt satta riktlinjer för användbarhet behöver uppdateras och korrigeras efteraktuella uppfattningar hos så väl experter så väl som vardagliga användare idag.Det finns idag ingen känd forskning inom ämnet där användarens tolkning avanvändbarhet involveras vilket öppnar nya möjligheter till att förbättra existeranderiktlinjer ytterligare.Resultatet av studien visar att målgruppernas uppfattningar kompletterar varandramen tolkas på olika sätt. Medan experter, målgrupp 1, definierar användbarhet someffektivt, tillförståeligt och tillgängligt beskriver användarna, målgrupp 2, begreppetsom något enkelt och något som finns lättillgängligt och brett. Studiens främsta ochmest användbara resultat är att målgrupp 1 utvecklar efter normer framförriktlinjer, och målgrupp 2 vill ha produkter byggda på standarder och normer. / Usability is a central and common concept in the process of developing a usableand easily understood website for world wide web’s users. Usability strives förefficiency and satisfaction, the website’s users should be able to perform their taskswith minimum effort and within a reasonable time limit.This bachelor thesis will review the need of usability and how experts and usersinterprete the concept. How can the different interpretations of usability affect theneed of usability online on the world wide web, and how important is a navigationdesigned with usability in mind?This thesis will be based on a former study within the subject usability, aninterview study that is questioning the guidelines of usability today.The understandings on usability will be determined through interviews with eightinterviewees, four experts and four users. The examination aims to strength orlower the hypotes “Existing guidelines for usability needs an update andreformulation to fit the understandings from experts and users of world wide webtoday.”There is no earlier studies on the matter where users are asked to define usability,it is more common to ask users what they think of the usability on a specificproduct.The results of this study shows that the two audiences understandings completeseach other but are interpreted differently. Audience 1, the experts, defines usabilityas something efficient and easily learnable, while audience 2, the end-users, definesthe concept as something simple that is easily accessible and widely spreadthroughout the world wide web. The most interesting result of the study is theresults that shows how the experts develop with norms and standards in mindinstead of guidelines and the end-users wants products built on standards thatthey recognize.

This project will be based in an objective and as well as subjective study related to Quality of Experience in a video conference application, appear.in. Indeed the study puts emphasis on finding possible correlations between Quality of Service parameters, that in the study are represented by some of the most meaningful network parameters, and contextual parameters with Quality of Experience. To achieve this the study was based in two different scenarios using two test environments. One is based on having an all free test and the other conducted in a created test-bad for monitoring and altering network parameters to see how user respond to the changes. Both scenarios were accompanied by a survey that provided useful information about the subjective perception of different individuals that took part in the testing phase.The project is divided in two phases where we set up the required environments for the test and then we process results to find correlation between the above mentioned parameters.In the end of the project all the results and the conclusions are presented providing a clearer view for what was done. The project itself might represent a good foundation to be used in the future for other studies related to video conferencing application.

This targeted research study, carried out by an officer of the Turkish National Police (TNP), investigated the perceptions and beliefs of TNP trainers and trainees towards the potential adoption and implementation of e-learning technology for in-service police training. Utilizing diffusion and innovation theory (DOI) (Rogers, 1995) and the conceptual technology integration process model (CTIM) (Nicolle, 2005), two different surveys were administered; one to the trainers and one to the trainees. The factor analyses revealed three shared trainer and trainee perceptions: A positive perception towards e-learning, personally and for the TNP; a belief in the importance of administrative support for e-learning integration; and the belief in importance of appropriate resources to facilitate integration and maintain implementation. Three major recommendations were made for the TNP. First, the research findings could be used as a road map by the TNP Education Department to provide a more flexible system to disseminate in-service training information. The second is to establish two-way channels of communication between the administration and the TNP personnel to efficiently operationalize the adoption and integration of e-learning technology. The third is the administrative provision of necessary hardware, software, and technical support.

Trata-se de um estudo descritivo, de abordagem qualitativa, do tipo estudo de caso, cujo objetivo é analisar a Estratégia Saúde da Família (ESF) através da perspectiva do seu usuário, verificando o grau de correspondência entre os serviços oferecidos pela ESF e a proposta oficial, norteadora da Estratégia. Neste intuito, realizamos entrevistas com usuários cadastrados na Unidade de Saúde da Família - Centro, no município de Piraí, interior do estado do Rio de Janeiro. Na busca do arcabouço teórico, nos aprofundamos em temas como qualidade dos serviços de saúde, Sistema Único de Saúde, no Programa de Agentes Comunitários de Saúde e Saúde da Família. Ao analisarmos os resultados, dividimos os achados em três categorias. São elas: caracterizando os sujeitos; utilização dos serviços de saúde à luz do acesso, acolhimento e vínculo e, por fim, a percepção do usuário: avaliação, crítica, elogio e sugestão. Ao fim da pesquisa, concluímos que, como todo serviço, necessita ser avaliado e monitorado, levando em consideração as críticas e elogios abordados, buscando melhor qualificação. Acreditamos que repensar o modelo de atenção à saúde, dentro da perspectiva para qual aponta a estratégia saúde da família, implica em assegurar correspondência entre os serviços de saúde e as expectativas e valores socioculturais da população usuária. / This study describes qualitatively, from the health system user point of view, family health strategies (FHS) regarding correspondences between offered FHS services and the strategies of official guidelines. For the stated reason, we interviewed health system users subscribed at Downtown Family Health Unity of countryside Piraí municipality, Rio de Janeiro State. Searching for theoretical bases, we probed/studied health services quality in Brazilian Health System, specifically at Health community agents and family health programs. Our work results can be divided in three categories: subjects ranking; services utilization by means of assess; reception and bondage; and finally, perceptions of users such as evaluation, critics, commendations and proposals. We conclude lastly that as all services need to be evaluated and monitored considering all the critics and praises approached in order to reach a better qualification. We believe that re-evaluate/rethink the actual model of health attention, having as perspective family health, implies in assuring the correspondence between health services and the expectations and sociocultural values of the health user group.

Technology is developing at a rapid pace. With this, Internet of Things (IoT) and smart homes are being used by more and more people every day. The amount of network protocols that is being used in relation to smart homes are many and they come with different features and challenges. With one of the main challenges being the issue of interoperability between the protocols. This has led to the introduction of Matter, a new protocol that uses Thread, Wi-Fi and Ethernet as networking technologies underneath. The goal is to enable smart devices from different companies to seamlessly talk to each other. There is a gap in how the different protocols are perceived by users as well as how a standardized protocol like Matter could impact the experience of a smart home. The aim of the study is to better understand the need of consumers for their smart home protocols. This by using a mixed method approach to get the insight of consumers located in Sweden. The data in the study was collected by conducting a survey and two focus group sessions. The survey was answered by 34 respondents and was structured to answer research question 1. The focus group had 4 participants in the first session and 3 participants in the second session and was structured to answer research question 2. Thematic analysis was used to analyze the collected data which concluded into 7 themes from the survey and 5 themes from the focus groups.  The findings were then discussed subsequently with each theme. Using UTAUT2 as the theoretical framework the similarities and general findings were connected to the constructs of the UTAUT2 model. The themes showed that the perception of protocol is closely tied to its influence on factors like performance, reliability, and functionality of smart home devices. Additionally, it was concluded that adopting a standardized protocol such as Matter could potentially enhance interoperability, make it less complex, and address security and privacy concerns. As a result, this could significantly impact the user experience of individuals in their smart homes.

The dissertation discusses the impact of change management during the implementation of an IT system. The theoretical part of the dissertation is aimed at gaining information about human performance, and the implications during the implementation of the system, and also post-implementation. Literature suggests that the human factor is the key to the successful implementation of system projects. The study, which is qualitative in nature, makes use of face-to-face interviews for the collection of evidence, as well as questionnaires as add-on tools to support the underlying constructs and research questions posed within the study. The use of data obtained from the research interviews, as well as survey data, has provided the research study with the necessary validity, reliabilityand trustworthy data to support the research results, findings – and to be able to make some recommendations. The reason for the failure of system implementation projects is often due to poor implementation during the project. It is important to place the importance of people on a par with technology and processes. A holistic approach would be the most likely to result in the acceptance – and the efficient and effective use of the implemented system. Communication, training and management participation are common means of addressingany fears of change, and to build trust. This information should be utilised by project teams during implementation projects, as it should help to provide the necessary framework to ensure the success of the change initiatives.

No. of bitstreams: 1 Dissert Sergio Ricardo.pdf: 2836987 bytes, checksum: 43815c6755b861d585a7bab20e42a98d (MD5) Previous issue date: 2010 / O presente trabalho tem como seu principal objetivo avaliar os resultados alcançados com a implantação do sistema de medição individualizada de água em prédios populares abastecidos pela Empresa Baiana de Águas e Saneamento e que anteriormente possuíam medição coletiva.Quinze prédios situados na cidade do Salvador, Estado da Bahia, fizeram parte deste estudo.O método usado para a análise envolveu três aspectos: primeiro, a avaliação do padrão de consumo de água após implantação do sistema de hidrometração individualizada. A partir dos registros de consumos obtidos no Sistema Comercial da Embasa com o histórico de consumos referentes aos 24 meses que imediatamente antecederam à individualização da medição de água e aos 24 meses que a sucederam, o estudo constatou que o Indicador de Consumo Mensal no período com medição coletiva era equivalente a 18m3 por apartamento e passou para a média de 14m3 por apartamento após a hidrometração individualizada. O segundo aspecto foi a avaliação econômica da concepção de projeto adotada pelos prédios populares de Salvador, baseada em dois fatores: o custo necessário para execução da obra de adaptação hidráulica e a expectativa de ganho financeiro nas contas de água e esgoto decorrente da redução do consumo médio de água após utilização dessa nova forma de medição. O resultado mostrou que existe viabilidade financeira para essa tipologia de edificação considerando que o tempo de retorno do investimento foi inferior a três anos e a rentabilidade a partir desse período foi superior a da caderneta de poupança. O terceiro aspecto foi a avaliação da percepção do usuário sobre esse sistema de medição a partir de informações colhidas através de uma pesquisa de opinião realizada com 32 moradores dos quinze prédios, nos meses de novembro e dezembro de 2009, por meio de visitas no local. O estudo também fez uma comparação dos resultados obtidos nesta pesquisa de opinião como os resultados de outra feita anteriormente em prédios populares com medição individualizada situados em bairros do subúrbio da cidade.Este estudo verificou que com a mudança do critério de medição, considerando-se os dois anos com medição coletiva e o mesmo período com medição individualizada, houve um impacto de redução de 22% no consumo dos apartamentos dos prédios estudados, para um intervalo de confiança (IC) de 95%. A pesquisa de opinião realizada constatou um alto nível de aceitação dos condôminos ao novo sistema de medição, que alcançou 95,2%. / Salvador
