User modelling is an old research discipline. The main concern of this discipline is to improve the quality of human-computer interaction predictive goals, preferences and context. Thus, adaptation and personalization of a document or an application for a particular user need to have information on the latter. It often referred to as “user profile”. A user profile modelling process must be done in...
In Human Activity Recognition (HAR) supervised and semi-supervised training are important tools for devising parametric activity models. For the best modelling performance, typically large amounts of annotated sample data are required. Annotating often represents the bottleneck in the overall modelling process as it usually involves retrospective analysis of experimental ground truth, like video footage...
While the modeling of QoE has made significant advances over the last couple of years, currently existing models still lack an integration of user behavior aspects and user context factors along with the consideration of appropriate temporal scales. Therefore, the goal of this paper is to present a comprehensive QoE and user behavior model providing a framework which allows joining a multitude of...
The objective of this paper is to put forward a discussion of how a better understanding of the issues surrounding control can be an important element in the development of generativity strategies in business models for mobile platforms, such as Apple's iPhone. Generativity refers to “a technology's overall capacity to produce unprompted change driven by large, varied, and uncoordinated audiences”...
In this work we approach the study of team situation awareness based upon a holistic perspective that integrates the shared and distributed nature of the construct. We studied team situation awareness in the context of critical incidents response management, as it constitutes a valuable asset and yet is continuously challenged by the very nature of the context. We applied a micro world approach as...
Next generation mobile services will be composed of services components offered by different third-party providers. Complex services ecosystems will be supported by partnership agreements that will explore different application-aware pricing models. Such pricing models are based on service description information and are a central enabler for billing. However these composite services pricing models...
Rich and attractive mobile services have been developed as result of technological advances and emergent mobile business models. Product launching has been improved through packaging and orchestration of services components using service composition techniques. The design of charging systems, which can explore partner information, is a strong enabler for mobile composite services ecosystems. The authors...
The Internet of things(IoT) is considered to be the next step in the revolution of internet, the combination of the Internet and emerging technologies such as nearfield communications, real-time localization, and embedded sensors,which lets us transform everyday objects into smart objects that can understand and react to their environment.With an increasing diversity of RFID devices integrated in...
This paper reviews what theoretical models of technology evaluation are used in mobile work context. We examine how these models are extended to take mobility and organisational contexts into account. We found that most of the extensions were related to mobile task and mobile technology aspects but also costs, impacts and organisational viability were added. The paper provides discussion on the strengths...
Whether or not mobile Internet services add value depends on the context and objective in which they are used. In this paper, we examine whether consumer attitudes towards the added value of mobile services in specific contexts has a positive impact on their general intention to adopt mobile Internet services, by analyzing the results of a large-scale consumer survey. The results indicate that context-of-use...
This paper proposes an integrated conceptual model for analyzing user adoption behaviors towards mobile marketing platforms from a two-sided market perspective. Both the consumer side and the merchant side are modeled based on extending classical theories with newly introduced factors reflecting cross network effects, and the two sides are integrated in the overall model which reveals the dynamic...
Technology diffusion theory is mainly focused on technology adoption, while prerequisites to such adoption are largely disregarded or taken for granted. The study argues that the in-depth analysis of what comes prior to adoption and use of technology – what we define “technology activation” – is equally important, so as to spot industry-specific characteristics that enable or hinder a value proposition...
With the good customer foundation and increasing revenue, m-commerce is on the growing development stage. Although there are many literatures about the factors affecting customer intention in internet-based e-commerce contexts, it is necessary to do an empirical validation in m-commerce contexts. Factors of trust and social influence integrated to TAM were used in the conceptual model. Empirical data...
This paper identifies and discusses a set of conceptual issues relating to institutional strategies for enabling the embedding of learner-centric hybrid learning processes within educational institutions. Starting with the Ecology of Resources model of learning, we identify "filters" that limit the adoption of new and hybrid learning processes in formal contexts. The related "boundary"...
This paper addresses the problem of developing a way to conceptualize context that can support the development of technology-rich learning activities. The term technology-rich encompasses mobile, hybrid and on-line learning approaches and the work reported here is intended to bridge these different approaches. In this paper we suggest that a learner specific definition of context can ground research...
Television and video consumption are growing rapidly worldwide, driving usage of second and third screens for related interactions and information. Since television has a proven impact on consumer purchase behaviors, there is commercial interest in technologies that model viewers' intent, interests and engagement. However, the ecosystem currently faces two challenges - audience fragmentation and a...
Mobile data services (MDS) have been attracting increasing scholarly attention in recent years. In this paper, a cross-disciplinary model, established with established critical factors derived from traditional information systems models and the means-end chain approach, is used to explore what affects customers' willingness to pay for MDS. In addition, the hybrid framework highlights the multiple...
Objective of this research is to investigate customers' adoption of M-payments by examining the adoption determinants that are specific for the M-payment context. For this aim, we are going to review some adoption theories and previous studies which have been done in adoption of m-payment area and extract the most significant factors and finally develop appropriate model for Iranian customers. The...
Mobility of persons and goods currently represents an interesting field of application for innovative ICT tool as Radio Frequency Technology (RFID). RFID technology is increasingly spreading in logistics activities, such as warehouse management, supply chain traceability. RFID could support an automatic vehicle and person identification system by reduced investment costs. In the present paper, authors...
