Survey was applied with 162 teachers at distance of Universidade Federal da Paraíba Virtual, issue focusing on the perceived characteristics of innovation, attitude and intention about the use of Moodle. Multivariate statistical techniques were performed: 1) content-vality to analyze the complete structure of scale for relevance and representativeness of items and to verify which items refer to construct in question; 2) exploratory factory analysis to know the structure of interrelationship of the original variables of IDT; 3) confirmatory factor analysis to guarantee conceptual validity for the pattern observed; 4) coefficient alpha to verify the homogeneity of set of items; 5) ANOVA to verify the likely differences between the groups of respondents; and 6) multiple regression analysis to analyze the relation between constructs. Results showed that not all factors of IDT had effect on attitude and intention. Only three constructs had significant effect on attitude and/or intention: relative advantage+compatibility for work style (β = 0,792), visibility (β = 0,166) and result demonstrability (β = 0,152). Moreover, teachers had a positive attitude in relation to use of Moodle and a positive intention in relation to use in the future. It was not possible to confirm all the relation of TAM, probably this verification was been compromised for some problems in the measurement process, thus, the only unsupported relationship of TAM was the effect of complexity on attitude. An academic contribution was that although some constructs of IDT did not show effect on the constructs of TAM, the model provided evidence of appropriated application of constructs of TAM with IDT to measure attitude and intention of use of Moodle. A management contribution was the understanding and prediction the teacher s behavior in relation to adoption and use process of Moodle, being possible to verify the effectiveness of innovative project of distance learning in the UFPB Virtual. / Nesse estudo, o modelo de pesquisa baseado no modelo de aceitação da tecnologia (Technology Acceptance Model - TAM) (DAVIS et al., 1989) e na teoria da difusão da inovação (Innovation Diffusion Theory - IDT) (ROGERS, 2003) foi usado para analisar a relação entre as características de inovação e o comportamento dos docentes no processo de adoção e de uso do Moodle em cursos de graduação a distância. Foi utilizada uma estratégia de levantamento (survey) aplicado a 162 docentes a distância da Universidade Federal da Paraíba Virtual, focando questão sobre as características percebidas de inovação, atitude e intenção em torno do uso do Moodle. Foram realizadas técnicas estatísticas multivariadas: 1) validação de translação para analisar a estrutura completa das escalas em relação à pertinência e representatividade dos itens e a verificação de que os itens propostos remetem ao construto em questão; 2) análise fatorial exploratória para conhecer a estrutura das inter-relações das variáveis originais da IDT; 3) análise fatorial confirmatória para garantir a validade conceitual para os padrões observados; 4) alpha de Cronbach para verificar a homogeneidade do conjunto de itens das escalas; 5) ANOVA para verificar as possíveis diferenças entre os grupos de respondentes; e 6) análise de regressão múltipla para analisar a relação entre os construtos. Os resultados revelaram que nem todos os fatores da IDT tiveram efeito sobre atitude e intenção. Apenas três construtos apresentaram efeito significativo sobre a atitude e/ou intenção: avanço relativo+compatibilidade por estilo de trabalho (β = 0,792), visibilidade (β = 0,166) e demonstrabilidade de resultado (β = 0,152). Além disso, os docentes tiveram uma atitude positiva em relação ao uso do Moodle bem como uma intenção positiva em relação ao seu uso futuro. Não foi possível confirmar todos os relacionamentos do TAM, provavelmente essa verificação foi comprometida por alguns problemas no processo de mensuração das escalas, sendo assim, o único relacionamento do TAM não suportado foi o efeito de complexidade sobre atitude. Uma contribuição acadêmica foi que apesar de alguns construtos da IDT não terem apresentado efeito sobre os construtos do TAM, o modelo forneceu evidência de aplicação apropriada dos construtos do TAM com os da IDT para medir a atitude e intenção de uso do Moodle. Uma contribuição gerencial foi a compreensão e previsão do comportamento dos docentes EaD em relação ao processo de adoção e uso do Moodle, possibilitando verificar a efetividade do projeto inovador de EaD na UFPB Virtual.

L'intégration des tablettes numériques à écran tactile dans l'éducation de la petite enfance est prometteuse, mais difficile. Les trois principaux acteurs impliqués dans cette intégration sont l'enfant, le parent et l'enseignant. Cette thèse porte sur la manipulation des tablettes par le jeune enfant, les attitudes des parents et l'acceptation de ces dispositifs par l'enseignante ou par l'enseignant, afin de répondre à la question de l'efficacité de l'intégration des tablettes à écran tactile dans l'éducation de la petite enfance. Dans la partie sur l'enfant, deux études ont été menées. La première étude explore les comportements de manipulation numérique des enfants sur des tablettes à écran tactile et a conclu que la difficulté technologique d'une application de jeu dans les tablettes importe plus que la difficulté du contenu. La deuxième étude porte sur l'efficacité de l'ajustement des difficultés d'adaptation dans l'apprentissage basé sur le jeu pour ce qui est de l'acquisition des habiletés cognitives et du plaisir de l'enfant. De plus, les résultats indiquent que la conception du jeu a des répercussions importantes sur la compréhension de l'enfant et la manipulation numérique, et que l'adaptation aux difficultés d'adaptation a eu une influence positive sur le rendement cognitif de l'enfant en littératie, en mathématiques de base et en dessin, alors qu'aucune différence significative n' a été constatée dans l'expérience de plaisir de l'enfant entre le groupe expérimental et le groupe témoin. Dans la partie parents et enseignants, basée sur les résultats de l'enquête et des entretiens, les parents ont une attitude positive à l'égard des tablettes à écran tactile intégrés dans l'éducation de la petite enfance et ils croient fermement que les tablettes peuvent améliorer l'apprentissage des enfants. Pour les enseignants, il a été constaté que l'âge est l'élément clé qui influe sur leur acceptation de l'utilisation des tablettes numériques dans leur pédagogie, et les enseignants s'attendaient à recevoir des instructions plus pratiques sur l'utilisation de ces outils. / Integrating touch screen tablets in early childhood education is promising but challenging. The main three subjects involved in this integration are child, parent and teacher. This dissertation investigated child manipulation, parent attitudes and teacher acceptance respective to answer the question of the effectiveness of integrating touch screen tablets in early childhood education. In the Child part, two studies were conducted. The first study explored child digital manipulation behaviors on a touch screen tablets and made a conclusion that technology difficulty in a game app in the tablets matters more than content difficulty. The second study investigated the effectiveness of the adaptive difficulty adjustment in game-based learning in child cognitive skills achievement and enjoyment experience. And the results indicated that the game design significantly impacts on child comprehension and digital manipulation and the adaptive difficulty adjustment positively influenced child cognitive skills achievement in literacy, basic mathematics and basic drawing while no significant difference was found in child enjoyment experience between the experiment and control group. In the Parent and Teacher part, based on the survey and interview results, parents hold positive attitude towards touch screen tablets integrated in early childhood education and they strongly believed the potential of tablets to improve children learning. For teachers, it was found that the age is the key element impacting their acceptance of using tablets in their pedagogy, and teachers expected more practical instruction of using tablet in their teaching.

This study sought to understand the relation between travel information, PT use intentions and non-habitual travel (at night). The hypothesis is that PT use intentions are related to the perceived usefulness and the ease-of-use of the system, which are related to information quality and real-time information availability. The hypothesized relations are anchored theoretically in the Extended Technology Acceptance Model and validated empirically in two sources of data: (i) Copenhagen (Denmark), characterized by a highly integrated PT system with an advanced web-based information system; (ii) Recife and Natal (Brazil), characterized by a lower perceived Level Of Service (LOS) and non-integrated information sources. The data was collected through a tailor-made survey answered for 1,123 university students in Denmark and Brazil. Structural equation models were employed for explaining the use of PT as a function of the observed respondent characteristics and the latent constructs. The results show: (i) information quality is essential for explaining PT use; (ii) perceived information quality is directly and positively related to perceived LOS, convenience and familiarity with the PT system; (iii) the use of real-time information is positively related to information quality and familiarity, while it is negatively associated with perceived PT security; (iv) PT use at night is positively related to habitual PT use and information search / Com a rápida melhoria da tecnologia, acompanhada por mudanças no estilo de vida, e o crescimento das cidades, que tornou o transporte público (TP) muito mais complexo, entregar informação integrada do sistema de transporte de uma forma eficiente e clara é de extrema importância, mas nem sempre está disponível. Este estudo procurou entender a relação entre informações sobre viagens, intenções de uso de TP e viagens não habituais (à noite). A hipótese é que as intenções de uso de TP estão relacionadas com a percepção sobre a utilidade e a facilidade de uso do sistema, que estão relacionados com a qualidade da informação e a disponibilidade de informação em tempo real. As relações hipotéticas são ancoradas teoricamente na Extensão do Modelo de Aceitação Tecnológica e validado empiricamente através de duas fontes de dados: (i) Copenhague (Dinamarca), caracterizado por um sistema de transporte altamente integrado com um avançado sistema de informação baseado na web; (ii) Recife e Natal (Brasil), caracterizadas por um nível de percepção do nível de serviço como mais baixo e fontes de informação não integradas. Os dados foram recolhidos através de um questionário feito sob medida e respondido por 1.123 estudantes universitários na Dinamarca e no Brasil. Modelos de equações estruturais foram utilizados para explicar a utilização do TP em função das características observadas dos respondentes e os construtos latentes. Os resultados mostram: (i) a qualidade da informação é essencial para explicar o uso do TP; (ii) a percepção da qualidade da informação está direta e positivamente relacionada com a percepção do nível de serviço, conveniência e familiaridade com o sistema de TP; (iii) o uso da informação em tempo real está positivamente relacionado com a qualidade da informação e familiaridade, enquanto está associado negativamente com a percepção de segurança do TP; (iv) utilização do TP à noite está positivamente relacionada com a utilização habitual do TP e a busca de informações

The survey has been conducted about how older adults use digital services on the Internet, what their thoughts are about them and the problems that can arise during use. The purpose of the survey is to treat the qualitative data to see what factors affect older adults to use various digital services to operate in society. This purpose has arisen from the problem which older adults are the smallest but fastest growing user group to take advantage of digital opportunities, today's society more or less requires that you have some sort of digital knowledge to be able to benefit from its services. Based on the objective, we have formulated our research question "Older adults are the fastest growing group of digital users, but in total still the lowest represented user group. What contributes to the rapid rise and what can we learn from the users of today on how to develop digital services for this age group in the future?" We chose to write about this project because we think that the subject is relevant and interesting to explore. Since one can see the obvious problems regarding this in everyday life, we chose to more deeply explore the area to give us a broader view. We have used qualitative methods like observations and semistructured interviews, these have been applied from prior knowledge of how to perform these methods to enable a good data collection. We have also created our own modified model based on the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAUT) used to measure technology acceptance. The modified model is applied to the information we developed from them qualitative methods. The results from four informants indicate that there are critical factors that influence the use of digital services such as experience and needs, but these factors are individual and varies from person to person resulting in that there is not a single answer to the question but must be answered for each individual service.

This thesis describes effects of use and reasons for using three different organisational innovations: ISO 9000, Information and Communication Technologies (ICT) and an administrative tool (the YAF-module) in the Swedish Sports Confederation’s system Swedish Sports Online. This is done through three separate studies. The first study is directed at Swedish Small and Medium Sized Enterprises (SME) and the two following studies are directed at Swedish sport associations. The thesis contains three separate essays presenting the studies and an introductory part where the studies are compared. In the introductory part of the thesis the interaction patterns between organisation and innovation are compared and discussed. I discuss the level of effort put into the decision and implementation processes, and how this is related to the satisfaction with the innovations. The patterns that emerged are quite different in the three studies. Understanding these different interaction patterns between organisation and innovation is a step away from a beneficial/ detrimental dichotomy of innovations. The decision and implementation processes differ between the three studies regarding what parts of the organisations were involved. In the first study we saw top down decision and implementation processes, whereas in the second study we saw bottom or middle up processes. In the third study the decision and implementation was much narrower in scope, often involving only one person. I also describe how all perspectives (efficient choice, forced selection, fad and fashion perspective) suggested by Abrahamson (1991), bear some grain of truth for the adoption of ISO 9000 by SMEs and adoption of ICT by sport associations, whereas imitation (the fad and fashion perspectives) is less important in the adoption of the YAF-module. Furthermore, I discuss the parallels between human and organisational decisionmaking. Summary of the first essay – The aim of the first study is to investigate the effects of quality management in accordance with the ISO 9000 as viewed by both quality managers and other managers. We also consider the way companies carried out the recertification process to ISO 9001:2000 and what consequences different approaches brought. The study is based on Swedish SMEs with an ISO 9000:1994 who had recertified according to the ISO 9001:2000 standard. The strongest, most obvious and most valued effects of the ISO 9000 standard are clearer and more apparent working procedures and responsibilities. The most apparent problem is bureaucracy, which according to some managers can lead to reduced flexibility. The effects of the certification vary depending on how the certification project is conducted and how consultants are used. Summary of the second essay – This essay presents a descriptive study of the use of information and communication technology (ICT) and the change in communication patterns in Swedish sport associations over the period 1994 to 2003. The change is discussed in light of Internet and broadband diffusion. Results show that new channels for communication have been adopted, primarily Web sites and e-mail, but few established channels have been dropped. While there are associations that save time and money and increase the spirit of community using ICT, many organisations experience the increased number of communication channels as a burden since maintaining them takes extra resources but the benefits are not always easy to detect or measure. Certain characteristics common among non profit organisations (NPOs) as well as Internet and broadband access have influenced the development of ICT use. Summary of the third essay – This essay presents a new model for analysing adoption of discretionary, public information systems (PIS) with digital use patterns (such as use or non-use, as opposed to frequency of use, or degree of engaged or compliant use). The model is based on Rogers’ innovation diffusion theory (IDT) and Nilsson’s user centred access model (UCAM). The model is an alternative to the general technology acceptance model (TAM). The AKAM-Model identifies six prerequisites for use and four management approaches and describes how these are related. To illustrate its applicability, the AKAM-Model is used to analyse the adoption of a specific module, the YAF-module, in the Swedish Sports Confederation’s (SSC) system Swedish Sports Online. We present empirical results that indicate the frequency and importance of the barriers and driving forces as experienced by the YAF-module users and the potential YAF-module users. / Denna avhandling beskriver effekterna av, och skälen för, användning av tre organisatoriska innovationer: ISO 9000, informations- och kommunikationsteknologi (ICT) och en administrativ modul (LOK-stödsmodulen) i Riksidrottsförbundets system Svenskidrott Online. Avhandlingen presenterar tre olika studier samt en kappa där studierna diskuteras och jämförs. Den första riktar sig mot svenska små och medelstora företag, och de två följande studierna riktar sig mot svenska idrottsföreningar. I den inledande delen av avhandlingen diskuterar jag interaktionsmönstren mellan organisation och innovation och jämför mellan de olika studierna. Jag diskuterar hur mycket kraft som läggs på besluts- och implementeringsprocessen, och hur detta är relaterat till nöjdheten med innovationen. Mönstren som framträder är olika mellan de tre studierna. Att förstå dessa interaktionsmönster är ett steg bort från dikotomin förbättring/försämring rörande innovationer. Besluts- och implementeringsprocesserna skiljer sig också mellan studierna avseende vilka delar av organisationen som är inblandade. Den första studien handlar om ”topdown” processer medan den andra studien handlar om ”bottom-up” eller ”mitten-upp”- processer. I den tredje studien var besluts- och implementeringsprocesserna betydligt mindre omfattande, ofta var endast en person inblandad. Jag beskriver också hur alla, av Abrahamson (1991) föreslagna perspektiven (efficient choice, forced selection, fad and fashion-perspektiven) har ett korn av sanning för adoption av ISO 9000 och för adoption av ICT medan imitation (fad and fashion-perspektiven) är mindre viktigt för adoption av LOK-stödsmodulen. Utöver detta diskuterar jag också tänkbara paralleller mellan individuellt och organisatoriskt beslutsfattande. Sammanfattning av den första studien – Syftet med studien är att undersöka effekterna av kvalitetsledning i enlighet med ISO 9000, som de upplevs av både kvalitetschefer och andra chefer. Vi beaktar också hur företagen genomför omcertifieringsprocessen till ISO 9001:2000 och vilka konsekvenser olika genomföranden fick. Studien fokuserar på svenska små och medelstora företag med ett ISO 9000:1994 certifikat som senare omcertifierat sig enligt ISO 9001:2000. De starkaste, tydligaste och högst värderade effekterna av ISO 9000 är tydligheten i arbetssätt och ansvarsfördelning. Det största problemet är byråkrati som kan leda till minskad flexibilitet. Effekterna av certifiering varierar beroende på hur certifieringsprojektet genomfördes och hur konsulter används. Sammanfattning av den andra studien – Denna studie är deskriptiv och fokuserar på hur ICT används och hur kommunikationsmönstren förändrats i svenska idrottsföreningar under perioden 1994 till 2003. Förändringen diskuteras i ljuset av utbredningen av Internet och bredbandsuppkoppling. Resultaten visar att idrottsföreningarna har börjat använda nya kommunikationskanaler, främst hemsida och epost, men ofta inte slutat använda traditionella kanaler. Det finns föreningar som har sparat både tid och pengar samt ökat gemenskapen genom att använda ICT. Många föreningar upplever dock de nya kanalerna som en börda, i de fall de inte slutat använda några traditionella kanaler. Vissa faktorer utmärkande för ideella organisationer och vissa faktorer utmärkande för Internet- och bredbandstillgång har påverkat ICT-användningen. Sammanfattning av den tredje studien – I denna studie utvecklas en ny modell (AKAM-modellen) för att analysera adoption av valfria, publika informationssystem (PIS) med digitala användningsmönster (d.v.s. användning eller ingen användning till skillnad från grad av användning). Modellen baseras på Rogers innovations- och diffusionsteori (IDT) och Nilssons användarcentrerade tillgångsmodell (UCAM). Modellen är ett alternativ till teknologiacceptansmodellen (TAM). AKAM-modellen baseras på sex förutsättningar för användning och fyra sätt att hantera PIS samt beskriver hur dessa är relaterade till varandra. För att illustrera tillämpbarheten av AKAM-modellen, använder vi den för att analysera adoptionen av LOK-stödsmodulen i Riksidrottsförbundets system Svenskidrott Online. Vi presenterar empiriska resultat som ger en indikation om hur vanliga och hur viktiga olika barriärer och drivkrafter är, för användare och potentiella användare av LOK-stödsmodulen. / <p>Report code: LIU-TEK-LIC-2008:10.</p>

Denna uppsats söker att undersöka svenska m-handelkonsumenters syn på m-handel, elektronisk handel på mobilen, i ett förtroendeperspektiv. Då 77% av Sveriges befolkning idag äger en smartmobil, är smartmobilanvändningen mer utbredd än tidigare (Svenskarna och internet, 2015). Men trots smartmobilernas tillväxt har inte m-handel följts upp i samma takt och många föredrar fortfarande ehandel. För att ta reda på vad som kännetecknar svenska konsumenters tankar kring m-handel när det gäller förtroende och få en inblick till vad som skapar förtroende för m-handel har denna undersökning skapats. För att besvara dessa frågor har en nätbaserad enkätundersökning genomförts med TAMmodellen som underlag för att avgöra vilka de mer bestämmande faktorerna är när det gäller acceptansen av m-handel. Baserat på denna empiri som samlats in från enkätundersökningen har sedan ett flertal fokusgruppsintervjuer genomförts med MoTEC-modellen som grund för att få fram konsumenternas inställning till m-handel i ett förtroendeperspektiv samt avgöra vilka faktorer enligt konsumenterna skapar förtroende. Resultatet av undersökningen visar att konsumenter i överlag har en positiv syn till förtroendet för mhandel, men att många använder sig av e-handel på datorn då vana skapar ökad trygghet. Säkra betalmetoder är centrala för upplevt förtroende och var det konsumenter tittade på först för att värdera upplevd säkerhet. Andra faktorer som skapar förtroende är goda gränssnittsegenskaper med tydlig och överblickbar layout, med en högre feltolerans. Samt välformulerat informationsinnehåll i kombination med gott rykte. / This paper aims to examine swedish consumers’ views on m-commerce, mobile commerce, while taking a focus on the trust perspective of these views. The expansion of smartphones have reached a higher level than before and today 77 percent of Sweden’s population owns a smartphone (Svenskarna och internet, 2015). However, the growth of smartphones can not be applied to m-commerce as the growth of m-commerce has not reached the same level, as many still prefers e-commerce over m-commerce. This study has therefore been conducted to get an understanding of what characterises consumers’ thoughts about the trust aspects of m-commerce and to get an overview of which factors are creating perceived trust. To answer these questions an online survey was created with the TAM model as an underlying source to determine which the more defining factors are when it comes to consumers’ acceptance of m-commerce. Based on the material gathered from the survey has a number of focus group interviews been carried out with the MoTEC model applied, to get more detailed information about consumers’ views on m-commerce from a trust perspective and determine which variables increase trust. The results indicate that consumers mainly have a positive view on the trust aspects of m-commerce, yet many still prefer e-commerce, arguing that habit has a big role for added perceived trust. Secure payment methods are central for perceived trust and was the first thing that consumers looked upon to estimate the level of security. Other central factors were good interface features including a simple and reviewable layout with a higher error tolerance, in combination with well-formulated informational content and a good reputation.

The growing popularity of the internet and its activities have opened a wide range of business opportunities especially in terms of e-business. Though, reports show that the adoption rate of e-commerce in developed countries seem to be striving, a lot of developing countries still struggle with slow e-commerce adoption rate. Democratic Republic of Congo (DRC) is one these countries where e-commerce adoption is still in its infant stages. However, because of the recent infrastructure improvements and the growth in telecommunication services in the country, internet penetration, more specifically, mobile Internet penetration is growing at a significantly fast pace. This could mean opportunities for e-business services in DRC. The objective of this research is to investigate the factors that could influence online shopping adoption in DRC. This investigation was carried out by adapting an extended version of the Technology Acceptance Model (TAM). A quantitative approach was used in the collection of data and the data was edited and analyzed using the programming language, R. Also, the analytical techniques used in conducting this research include: Descriptive Statistical Methods (Cross tabulation, frequencies) and inferential Statistical Methods (Logistic Regression, ANOVA and Chi square tests). The results from this research show that contrary to the conceptualized model in the literature review where the main constructs included: Perceived Ease of Use(PEOU), Perceived Usefulness(PU) and Perceived Trust(PT), it appears that Perceived Ease of Use(PEOU) does not have any significance in a user’s intention to shop online(p>0.01). However, this research found that Perceived Usefulness and Perceived Trust have a strong statistical significance to a user’s intention to shop online. Furthermore, we found that Gender, Income and Age do not have any moderating influence on the relationship between a user’s perception and their intention to shop online in DRC. However, when the relationship between VI perception and intention to shop online is moderated by experience, we find that there is a variation between users with prior online shopping experience and those without. While these research findings make for remarkable recommendations on a user’s intention to shop online, we recommend that further research on actual usage of e-commerce be examined in DRC to get a better understanding of consumer online behaviors.

Purpose – It is argued that traditional audit methods are becoming outdated in terms of delivering sufficient assurance on business objectives, whereby, a paradigm shift towards continuous auditing (CA) is proposed and perceived as necessary both by academia, standard-setting groups, and business society. However, the practical prevalence of CA is insignificant in relation to the expectations depicted. Therefore, the purpose of this paper is to examine why this is the case by means of investigating what factors that motivate an adoption of CA amongst various internal audit functions (IAFs). Design/methodology/approach – The study draws on the Technology Acceptance Model (TAM), and data are obtained through semi-structured interviews capturing internal auditors’ attitude towards CA, and what factors that influence an adoption. Findings – There is a shattered view on CA amongst IAFs, where the proponents embrace it as a set of value-adding methodologies whilst the opponents argue that it falls outside their responsibility and threaten the independence of the function. Thus, why CA has not been leveraged to its full potential is, in contrast to previous research, not solely attributable to practical factors but also due to the IAFs’ vast differences in approach to CA as a concept. Practical implications – The study has brought attention to the distinguished disparity found in internal auditors’ attitude towards CA. Ultimately, doubts, whether CA should be leveraged by IAFs has come to light. These are hurdles that need to be considered, both by academia, standard-setting groups, and business society if the leap for CA ought to continue. Originality/value – The use of semi-structured interviews contributes to in-depth understandings and insights of the internal auditors’ attitudes towards CA. Moreover, such an approach is more likely to capture the stance towards CA in greater detail than that possible of previous large-scale surveys.

Avec le vieillissement de la population, le maintien à domicile des personnes âgées est devenu un enjeu majeur pour les pays développés et émergents. Parmi les solutions clés à explorer, les gérontechnologies sont considérées comme des plus prometteuses sans toutefois avoir apporté la preuve de leur efficacité pour l’autonomie domiciliaire, voire même être utilisables et acceptables pour le public visé. Dans ce contexte, une méthodologie de conception centrée-utilisateur a été mise en place pour proposer une plateforme d’assistance domiciliaire multi-tâches et multi-domaines (soutenant à la fois les activités quotidiennes, la sécurité de la personne et de son domicile et le lien social) ciblant un public âgé fragile en perte d’autonomie. Cette plateforme est appelée DomAssist. Sur la base d’une analyse des capacités physiques, cognitives et fonctionnelles en présence (étude 1) et des besoins d’assistance (étude 2) de notre échantillon d’étude, DomAssist a été conçu avec pour originalité une offre de services multi-domaines. En effet, la plateforme s’appuie d’une part sur un système de surveillance d’activités pour délivrer des assistances dites « context-aware » (étude 3) et d’autre part sur un système d’interaction homme-machine unifié et simplifié (étude 4), et ceci tout en promouvant l’auto-détermination (étude 5). Les résultats ont étayé la fiabilité du système de surveillance d’activités, et renforcé le bien-fondé de nos principes de conception concernant le système unifié d’interaction; et le soutien de l’auto-détermination. Notamment un rendu positif concernant l’utilisabilité et l’acceptabilité du système, et un effet bénéfique sur le sentiment de l’autodétermination des utilisateurs âgés ont été obtenus. De là, une dernière étude (étude 6) a évalué les bénéfices apportés après 6 mois d’utilisation de la plateforme, en termes de capacités fonctionnelles des participants fragiles, et de réduction du fardeau de l’aidant. Un effet positif (effet « protecteur » observé par les aidants professionnels) de DomAssist sur le statut fonctionnel des participants équipés (comparé aux contrôles) a été observé ainsi qu’une réduction du fardeau objectif de leur aidant. Au total, les résultats de ce travail pilote sont encourageants et ouvrent de nombreuses perspectives de recherche à fort potentiel d’impact sociétal concernant la problématique du maintien à domicile des personnes âgées / With the increase of life expectancy, aging in place is today a major concern for developed and emerging countries. Among the key solutions to explore, gerontechnologies are seen as the most promising. However, their evidence-based efficacy remains to be demonstrated for independent living or even for their usability and acceptance by the targeted old users. In this context, a user-centered conception methodology has been implemented for designing a multi-task and multi-domain (supporting everyday activities, safety, and social participation) assisted living platform targeting frail older adults with functional decline. This platform is named HomeAssist. Based on an analysis of physical, cognitive and fonctional abilities (study 1) and assistive technology needs (study 2) of our sample, HomeAssist has been designed with the originality of providing multi-domain services. Indeed, HomeAssist proposes an activity monitoring system to provide context-aware assistance (study 3), and a unified human-computer interaction system (study 4); while promoting self-determination (study 5). Results underpined the reliability of our activity monitoring system, and reinforced the rationale of our design principles, concerning the unified interaction system and the self-determination support. Notably, positive outcomes in terms of usability and acceptance of the system, as well as benefits concerning users’ feeling of self-determination have been obtained. From this, a last study (study 6) evaluated the benefits from a six-month use of HomeAssist, on functional abilities of frail older adults and caregiver burden. A positive effect of HomeAssist on functional status was obtained (“protective” effect reported by the professional caregivers), as well as a reduction of objective dimension of caregiver burden. Taken together, the results from these pilot studies are encouraging and open numerous research perspectives with high societal impact concerning the promotion of aging in place.
