A case study of MMO2's Madic: A framework for creating mobile internet systems

Mobile Internet applications on ubiquitous mobile networks allows real-time, anywhere, anytime connectivity to services. Due to its scalability and potential cost savings, mobile communication is being increasingly applied in the business and consumer communities to create innovative data and voice application, which run over the Internet infrastructure. This paper reports on a case study at an organisation that created an innovative approach to developing mobile applications developed by third party independent developers. A conceptual wireless reference model is presented that was used to define the various system components required to create effective mobile applications

Securing the Elderly: A Developmental Approach to Hypermedia-Based Online Information Security for Senior Novice Computer Users

Whilst security threats to the general public continue to evolve, elderly computer users with limited skill and knowledge are left playing catch-up in an ever-widening gap in fundamental cyber-related comprehension. As a definable cohort, the elderly generally lack awareness of current security threats, and remain under-educated in terms of applying appropriate controls and safeguards to their computers and networking devices. This paper identifies that web-based computer security information sources do not adequately provide helpful information to senior citizen end-users in terms of both design and content

ICT as an Enabler for Innovation Adoption

In this paper we investigate how two online services (a portal and a digital library) may influence the adoption of an innovation. It is known from prior surveys that the installation services branch of the Dutch building industry has a relatively slow adoption rate for innovations. We examine if these two online services can influence the attitude towards the adoption of innovations. From the academic literature we have derived a list of factors that influence the attitude towards adoption by individuals. We limited this project to a number of factors that are commonly referred to as technological factors. Using an online digital library and a custom-built portal, we conducted a field experiment with a post-test only control group design for one particular innovative product (a gas-analysis device); the test was performed using a survey. Our main finding is that the portal has a significant and positive effect towards the adoption of the innovation by an individual. We did not find a significant impact for the use of the digital library. On the basis of this experiment, we propose that online services that offer a high degree of interaction amongst their users are more likely to induce an increase in the willingness of an individual to adopt an innovation.innovation;adoption;digital library;portal;field experiment.

All across the circle : using auto-ordering to improve object transfer between mobile devices

People frequently form small groups in many social and professional situations: from conference attendees meeting at a coffee break, to siblings gathering at a family barbecue. These ad-hoc gatherings typically form into predictable geometries based on circles or circular arcs (called F-Formations). Because our lives are increasingly stored and represented by data on handheld devices, the desire to be able to share digital objects while in these groupings has increased. Using the relative position in these groups to facilitate file sharing can enable intuitive techniques such as passing or flicking. However, there is no reliable, lightweight, ad-hoc technology for detecting and representing relative locations around a circle. In this paper, we present two systems that can auto-order locations about a circle based on sensors that are standard on commodity smartphones. We tested these systems using an object-passing task in a laboratory environment against unordered and proximity-based systems, and show that our techniques are faster, are more accurate, and are preferred by users.Postprin

Measuring Mobile Portal User Satisfaction

With the rapid advancement of mobile technology, smart devices have challenged the extant research concerned with time and space. Based on a user’s specific interests, mobile portals allow quick and easy access, anywhere, anytime to a world of data, applications and services. Whilst this provides an enhanced, dynamic and personalized user experience, knowing how satisfied users are with their mobile portal is crucial to understanding users’ needs, identifying important factors in the improvement of existing mobile portals and enhancing Information Technology (IT)-related business value. The study extends research knowledge about user satisfaction to the context of mobile portals. Secondly it contributes knowledge regarding mobile portals, particularly concerning post-adoption mobile portal user satisfaction. Thirdly, the research contributes a new reliable and valid instrument to measure user satisfaction with mobile portals – a contribution to the research stream within the IS literature concerned with measurement

The role of Enterprise portals in Enterprise Integration

Today’s enterprises are moving business systems to the Internet - to connect people, business processes, and people to business processes in enterprise and across enterprise boundaries. The portal brings it all together: business processes, departmental sites, knowledge management resources, enterprise management systems, CRM systems, analytics, email, calendars, external content, transactions, administration, workflow, and more. The goal of this paper is to present the role of the Enterprise Portal in internal and external enterprise integration.Portal, Enterprise Portal, Integration, ETL, EAI, EII
