User-Centered Evaluation of Adaptive and Adaptable Systems

Adaptive and adaptable systems provide tailored output to various users in various contexts. While adaptive systems base their output on implicit inferences, adaptable systems use explicitly provided information. Since the presentation or output of these systems is adapted, standard user-centered evaluation methods do not produce results that can be easily generalized. This calls for a reflection on the appropriateness of standard evaluation methods for user-centered evaluations of these systems. We have conducted a literature review to create an overview of the methods that have been used. When reviewing the empirical evaluation studies we have, among other things, focused on the variables measured and the implementation of results in the (re)design process. The goal of our review has been to compose a framework for user-centered evaluation. In the next phase of the project, we intend to test some of the most valid and feasible methods with an adaptive or adaptable system

How E-Servqual Affects Customer\u27s Online Purchase Intention?

With the boom of Internet, Internet has become one of the consumers’ online shopping channels.

The result of this study will be available for those who interested in developing a transnational e-retailer as a reference, as well as academic research on cross-cultural comparative analysis

Customer Decisions to Use Online Food Delivery Services During The COVID-19 Pandemic

The coronavirus disease pandemic restricted dine-in service, and restaurants should adapt and rely heavily on no-contact operations and online food delivery services to sustain. Even though online food delivery technology is widely used in the food and beverages business, there is only a few research investigating the customers behavior intention on online food delivery technology in the coronavirus disease pandemic. This study aims to investigate the influencing factor of behavior intention on online food delivery platforms, by applying the technology acceptance model. An online questionnaire was applied to conduct the survey. The Partial Least Squares-Structural Equation Modeling approach was used to examine 417 respondents empirically. The results showed the significance of perceived usefulness, trust, social influence, and value co-creation in customer intention on online food delivery technology. The findings contribute to the body of knowledge about technology acceptance in an emergency event, specifically during a coronavirus disease pandemic. The practical implication of the study is managers of online food delivery services firms must identify their customers wants and needs

Adoption process of information technology (IT) innovations in organizations

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Several models have been developed for understanding and predicting innovation adoption in organizations and literature has identified several factors that impact the adoption and implementation of Information Technology (IT). This research examines the process of adoption of IT innovations in organizations. The study explores the processes involved in the adoption of IT and verifies the key factors that influence IT innovation adoption in organizations. Using a systematic literature review, the study developed a conceptual model of IT innovation adoption in organizations. The model is a theoretical combination of Diffusion of Innovation (DOI) theory, Theory of Reasoned Action (TRA), Technology Acceptance Model (TAM), Theory of Planned Behaviour (TPB) and a framework which contains characteristics of innovation, organization, environment, chief executive officer (CEO) and user acceptance. The model represents IT innovation adoption as a stage-based process, progressing from initiation to adoption-decision to implementation. The study aggregated findings of past research on IT adoption to identify key factors that influences IT adoption in organizations. The study performed a meta-analysis of innovation, organization, environment, CEOs and user acceptance determinants to assess the magnitude and the strength of these factors on IT innovation adoption. Results confirmed that relative advantage, compatibility, cost, observability and trialability are strong determinants of IT innovation adoption. In terms of organizational context, IS department size, top management support, organizational size, IT expertise, product champion, IS infrastructure, information intensity, resources and specialization was found influential in the adoption of IT. As for environmental characteristics, the meta-analysis verified the significance of external pressure, government support and competitive pressure. Meta-analysis results verified that CEO‟s innovativeness, attitude and IT knowledge as key determinants. The findings confirmed the importance of perceived usefulness, perceived ease of use, subjective norm and facilitating conditions for the user acceptance of IT in organizations

Effects and Implications of COVID-19 for the Human Senses, Consumer Preferences, Appetite and Eating Behaviour

As Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) evolved into a global pandemic, assessments of coronavirus disease 19 (COVID-19) patients have presented health conditions including, in many cases, a mild to severe loss of smell and tasting abilities among patients. Initial work has shown short and likely longer term negative effects on the human senses, with some indications of effects on consumer preferences; however, as of yet, very little is known about the impacts on eating behaviours and consequent longer term effects on appetite. The aim of this Special Issue anthology was, for the first time, to bring together researchers with key insights into how COVID-19 has impacted appetite and eating behaviours from the fundamental to the applicable, as assessed by human sensory perception. Thus, research is included that explores various themes, from the basic effects on the senses, to changes in consumer preferences, all the way to how and why COVID-19 has changed consumer behaviours in relation to food and eating in the longer term. Overall, we wished to document and bring together key research in the sensory and consumer space with respect to COVID-19, with the overall aim to highlight and ensure this research has a lasting impact regarding future understandings of measures developed to help and treat people affected during the ongoing pandemic

Risk and trust management for online distributed system

This thesis investigated the problem of strategic manipulation of feedback attacks and proposed an approach that makes trust management systems sufficiently robust against feedback manipulation attacks. The new trust management system enables potential service consumers to determine the risk level of a service before committing to proceed with the transaction

Studies and a model of appropriation of information and communication technologies in university students’ everyday life

This thesis investigated the appropriation of information and communication technologies in everyday life among university students and mature people. To that end, pertinent literature was reviewed resulting in the identification of three issues in need of a more careful appraisal by the HCI field. These issues were used as the research questions propelling this work; they include the identification of elements favouring the process of appropriation; the effect of a changing context on this process; and the co-existence of seemingly overlapping ICTs in people’s lives. A qualitative methodology was utilised in the studies reported in this thesis. Ethnographic work was conducted over a period of three months with fifteen masters students at the University of Glasgow in the UK. Further ethnographic work over a shorter time frame was conducted abroad among university students at Hokkaido University in Japan, Ajou University in South Korea and Nankai University in China. Additional ethnographic work was conducted among mature people in a religious community in Mexico. Qualitative data gathered was analysed using Grounded Theory and Structuration Theory. Two are the main contributions of this work. First, a number of insights providing some answers to the research questions posited in this thesis. These answers were advanced as a complement and expansion to issues previously identified in the literature as relevant in the process of appropriation. Because of the ecological perspective underlying this thesis, these answers were presented as technology-neutral and yet useful to understand how the appropriation of technology is induced and sustained, what the impact of a changing environment in the process of appropriation is, and how similar technologies with overlapping features can thrive in the same environment. The second contribution of this work was a three-layered model of appropriation of ICTs built from the identification of common patterns across the studies conducted. This model sought to detail the role of several intersecting large-scale social processes or structures (i.e., governments, various-sized private and state-owned organisations, the media, families and peers, as well as marketing practices, technical infrastructures and architectural spaces) that provide the resources and restrictions upon which the process of appropiation of digital technology rests. This framework was advanced as a simple tool to aid HCI researchers in the collection, analysis and reporting of qualitative data around the process of appropriation as shaped by the pervasive social structures of contemporary society. The limitations of the ethnographic work here reported, as well as those of the ensuing conclusions, are identified and used to suggest some avenues of future exploration around the appropriation of ICTs in daily life

Internet shopping - A taxonomy of consumer online actions.

This thesis applied the theory of activity and goal-directed action to the study of online shopping actions. It first studied qualitatively the structures of online shopping actions using the self-confrontation interview method. The qualitative findings established the structural, cognitive and dispositional dimensions of online shopping actions including knowledge and value structures, attention processes and flow. The typical behavioural traits of online shoppers were also identified. Findings also emerged about the tensions between consumers' online and offline actions and the consequences of the technological mediation of shopping. From these qualitative findings, a survey instrument was developed to query online shoppers on various dimensions of their online shopping actions. Cluster analysis of the survey results produced a taxonomy of consumer online actions from which a typology of online shoppers was generated. The qualitative findings on the typical behavioural traits of online shoppers were then used as criteria for the qualitative usability analysis of retail websites. Retail websites of four product and service categories were analysed for their usability, i.e. ability to accommodate the typical behavioural traits of online shoppers such as propensity to experience information overload and to multi-task, potential for experiencing affect and flow etc. This thesis made several theoretical, methodological and practical contributions. It extended goal-directed action theory beyond its traditional scope of work actions and group activity to the realm of consumer behaviour. It also introduced a different theoretical framework to consumer psychology by applying the theory of activity and goal directed action to consumer behaviour. It made a methodological contribution by applying the self-confrontation interview method to the study of online behaviour. This thesis' findings also have practical implications for the understanding of online behaviour, the diffusion of e-commerce and the design of Internet interfaces
