Gait Analysis Using Multiple Kinect Sensors
2014
A gait analysis technique to model user presences in an office scenario is presented in this chapter. In contrast with other approaches, we use unobtrusive sensors, i.e., an array of Kinect devices, to detect some features of interest. In particular, the position and the spatio-temporal evolution of some skeletal joints are used to define a set of gait features, which can be either static (e.g., person height) or dynamic (e.g., gait cycle duration). Data captured by multiple Kinects is merged to detect dynamic features in a longer walk sequence. The approach proposed here was been evaluated by using three classifiers (SVM, KNN, Naive Bayes) on different feature subsets.
VisAdapt: A Visualization Tool to Support Climate Change Adaptation.
2017
In this article we present the design and implementation of the web-based visualization tool VisAdapt, developed to support homeowners in the Nordic countries to assess anticipated climate change and climate related risks which are expected to negatively impact their living conditions. The tool guides the user through a three-step visual exploration process to facilitate the exploration of risks and adaptation measures, specifically adapted to the user. VisAdapt has been developed over the course of two years in close collaboration with domain experts and end users to ensure the validity of the included data and the efficiency of the visual interface. Although VisAdapt is designed for Nordi…
Nuadu Concept for personal management of lifestyle related health risks
2008
Majority of the health risks and diseases in the modern world are related to lifestyles, e.g., overweight, unhealthy diet, physical inactivity, sleep deprivation, and stress. Behavioral change towards healthy lifestyles is the key to the prevention and management of these risks, but early and efficient interventions are scarcely available. We present the Nuadu Concept, an ICT (Information and Communication Technologies) assisted wellness toolbox for the management of multiple, behavior-originated health risks. The concept is based on psychological models, which provide methods and motivation for behavior change. The individual is considered as the best expert of his/her own wellness. Thus, …
The effects of mobile banking application user satisfaction and system usage on bank-customer relationships
2016
This study examines mobile banking (m-banking) application usage in Finland by linking it with customer-bank relationship development. Specifically, we examine how usage is related to relationship commitment, overall satisfaction, intention to recommend the bank and future intentions to remain with the bank. A survey was used to collect data from experienced mbanking application users. In total, 273 valid responses were received. The results support the hypotheses and reveal that user satisfaction with m-banking application usage has a strong positive association with usage of m-banking applications. Usage, in turn, was positively related to all examined bank-customer relationship related v…
Accessibility of Norwegian Municipalities Websites: An Interactive Learning Environment Experimental Investigation
2016
Accessibility is an important aspect of websites generally and public websites particularly. Many ways could be proposed to enhance accessibility, however the impact of selected actions is hard to predict due to diversification and contradiction, in addition to the existence of the time factor. A System Dynamics simulation model including factors affecting the accessibility of Norwegian municipal websites was encapsulated in an Interactive Learning Environment (ILE). As the model promised to be able to change how users think and take decisions, this ILE was tested by users in an experiment. We have conducted a#x03B1;, a#x03B2;, and a#x03B3; change analysis on the results of this experiment.…
End-user ethics teaching: issues and a solution based on universalization
2005
The ethical aspects of computing have gained increasing attention at the professional level of education in universities. As a result, several works have been produced relating to computer ethics education at this level. However, the ever-increasing role and usage of computer technology means that ethical education related to computing is also necessary for non-professional/non-major computing/information systems students. Due to the differences between professional and non-professional education in terms of substance, along with pragmatic reasons (e.g. lack of resources), the ordinary end-users need a different educational program. This paper first explores issues (i.e. challenges and prob…
Mobile commerce: core business technology and intelligent support
2005
Mobile commerce is an emerging field in its early stages, but there are a number of ideas of what is going to constitute the key success factors for the actors in the global m-commerce arena. This arena is already growing diversified with a number of application areas, which are growing in different directions and at different paces. We understand already that B2B, B2E, B2C and P2P will produce rather different types of applications, because the propositions for value-added products and services are quite different. This is probably one of the reasons why the hunt for the “mobile commerce killer applications” has been in vain so far.
Nuances of Human-Centredness in Information Systems Development
2005
Numerous methods, methodologies, approaches, techniques and tools have been developed over the years to ensure successful accomplishment of information system development (ISD) projects in terms of user satisfaction. However, different methodologies and approaches perceive the user differently; sometimes the user is seen as an anonymous 'object' that is going to use the system, or as an evaluator confirming the correctness of the design, or even as a critical contributor along the way to user-friendly information system. Each of these approaches has their own benefits from the ISD point of view but they lack a holistic view of the user. In this paper, we will review the trajectories of ISD …
Enterprise Portal Personalization: Direct and Indirect End-User Effects, and the Moderating Effects of Gender
2009
Enterprise portals offer rich functionality for end- user personalization, but few studies have been conducted on the end-user effects of this feature. This article presents a study of end-user effects of personalization, using the combined technology acceptance model (TAM) and the theory of planned behaviour (TPB) as a research framework. We propose that personalization indirectly affects end-users' intentions through effects on ease of use, usefulness, attitude and behaviour control. In addition, it may have a direct effect on end-users' intentions to use enterprise portals that is not mediated by the variables of the combined TAM/TPB-model. Because previous studies have found gender diff…
Goal-Oriented Development of BDI Agents: The PRACTIONIST Approach
2006
The representation of goals and the ability to reason about them play an important role in goal-oriented requirements analysis and modelling techniques, especially in agent-oriented software engineering, as goals are more stable than other abstractions (e.g. user stories). In PRACTIONIST, a framework for developing agent systems according to the Belief-Desire-Intention (BDI) model, goals play a central role. Thus, in this paper we describe the structure of the goal model in the PRACTIONIST framework and how agents use their goal model to reason about goals, desires, and intentions during their deliberation process and means-ends reasoning as well as while performing their activities.
