Collaborative Mobile Clouds: An Energy Efficient Paradigm for Content Sharing

2018

On the way toward enabling efficient content distribution, reducing energy consumption and prolonging battery life of mobile equipment, an emerging paradigm, i.e., mobile cloud, which is based on content distribution, was proposed. As a mobile platform that is oriented toward content distribution, mobile cloud is also foreseen as an energy-efficient solution for future wireless networks. The benefits of using CMC for content distribution or distributed computing from social networking perspectives have been studied earlier. In this article, we first present the concepts of CMC and then discuss the energy-efficiency benefits from the system-level point-of-view as well as open challenges in d…

Energy harvesting for mobile agents supporting wireless sensor networks

2022

Abstract Wireless sensor networks (WSNs) have been deployed widely in many different application including in civil and military fields. The sensing data from the networks is very diverse and may cost huge energy consumption for transmission. Hence, mobile sensors with high capacity are deployed to support the static sensors dealing with longer range communicating distances and also supplying power wirelessly the sensors if possible. This paper focuses on an energy harvesting (EH) design for either mobile agents or sensor nodes in WSNs. A hybrid EH system can harvest energy from ambient environment around to power the mobile sensors and static sensors. In addition, these mobile sensors and …

Teachers' visual focus of attention in relation to students' basic academic skills and teachers' individual support for students: An eye-tracking stu…

2022

This study investigated how teachers' visual focus of attention is associated with students' basic academic skills and teachers' individual support for students in basic academic skills in authentic classroom settings. Teachers' (N = 46) visual focus of attention in the classroom was measured with mobile eye-tracking, and students' (N = 879) literacy and math skills were tested in Grade 1. The results revealed that teachers' visual focus of attention in terms of fixation counts correlated with students' basic academic skills and teachers' individual support for students in literacy and math. Two case studies showed that teachers' visual focus of attention varied among students with differen…

Experiences from the Use of an Eye-Tracking System in the Wild

2010

Eye-tracking systems have been widely used as a data collection method in the human–computer interaction research field. Eyetracking has typically been applied in stationary environments to evaluate the usability of desktop applications. In the mobile context, user studies with eye-tracking are far more infrequent. In this paper, we report our findings from user tests performed with an eye-tracking system in a forest environment. We present some of the most relevant issues that should be considered when planning a mobile study in the wild using eye-tracking as a data collection method. One of the most challenging finding was the difficulty in identifying where the user actually looked in th…

Refamilisation in the broadband society – the effects of ICTs on family solidarity in Finland

2021

In this article we explore the effects that new information and communication technologies (ICTs) have on family relations in Finland. The idea of ‘new connectivities’ works as a starting point for the study directing attention to ICT-mediated forms of being together with distant family members. The research data consists of 22 student reports encompassing a total of 133 informants from extended Finnish families. Extended group interview (EGI) technique was developed and used for data collection in order to grasp the underlying social practices and values behind the use of ICTs in extended families. The results show that new ICTs, especially mobile social media, enhance family solidarity am…

Using assessment for learning mathematics with mobile tablet based solutions

2014

Published version of an article in the journal: International Journal of Emerging Technologies in Learning (iJET). Also available from the publisher: http://dx.doi.org/10.3991/ijet.v9i2.3219 This article discusses assessment for learning in mathematics subjects. Teachers of large classes face the challenge of regularly assessing students’ ongoing mathematical learning achievements. Taking the complexity of assessment and feedback for learning as a background, we have developed a new approach to the assessment for learning mathematics at university level. We devised mobile tablet technology supported assessment processes, and we carried out user studies in both Rwanda and Norway. Results of …

Multi-agent control architecture for RFID cyberphysical robotic systems initial validation of tagged objects detection and identification using Playe…

2016

International audience; The objective of this paper is to describe and validate a multi-agent architecture proposed to control RFID Cyber-Physical Robotic Systems. This environment may contain human operators, robots (mobiles, manipulators, mobile manipulators, etc.), places (workrooms, walls, etc.) and other objects (tables, chairs, etc.). The proposed control architecture is composed of two types of agents dispatched on two levels. We find at the Organization level a Supervisory agent to allow operators to configure, manage and interact with the overall control system. At the Control level, we distinguish the Robots agents, to each robot (mobiles, manipulators or mobile manipulators) is a…

The Effects of Individual Values on Online Shopping Spending

2019

Although individual values have been found as important antecedents of human behaviour, their effects on online shopping behaviour remain poorly understood. In this study, we aim to address this gap in prior research by examining the effects of individual values on both total online shopping spending and the specific types of online shopping spending in terms of orders made (1) with traditional computers versus mobile devices, (2) from businesses versus other consumers, and (3) from domestic versus foreign online stores. The examination is based on the data from 565 Finnish online shoppers, which was collected via an online survey between February 2019 and March 2019 and is analysed by usin…
