Measuring expectation for an affordance gap on a smartphone user interface and its usage among older adults

2020

The smartphone has become a ubiquitous mobile communication tool that plays a crucial role in the daily lives for Malaysian older adults. However, it is not easy for older adults to learn new interaction modes and adopt the smartphone user interface. In this paper, we aim to examine the affordances of a smartphone user interface and its usage by older adults through the lens of Norman’s execution/evaluation action cycle (EEAC) framework. A mobile-user interaction study was administered with four tasks. A paired sample t-test was conducted to analyze the affordance gap between different levels of expectation. The results revealed that three tasks (making phone calls, adding contacts, and usi…

Mobile media, gender, and power in rural India

2019

This article traces the diffuse connections between mobility and power by exploring how mobile phone use contributed to gendered power relations in rural India. It is based on ethnographic fieldwork on the use of mobile phones, conducted periodically between 2005 and 2013 in the village of Janta in West Bengal, India, and compared to earlier fieldwork in Janta, before the village had any phone system. Analysis of the increased mobility reveals how mobile phone use emerges within interconnected, changing fields of power. The political sphere earlier perceived as predominantly local was replaced by translocal political practices characterized by increasing mobility. Although new political pra…

Multi-Skill Call Center as a Grading from “Old” Telephony

2009

We explore parallels between the older telephony switches and the multi-skill call centers. The numerical results have shown that a call center with equally distributed skills is preferable compared to traditional grading-type design. The annex contains a short version of mathematical proof on limited availability schemes design for small call flow intensity *** and for large *** . The proof explores one excellent V. Benes' paper (from Bell Labs). On its own merit, the annex could initiate new mathematical research in call center area, more by now the powerful software for numerical analysis is available. Main conclusion is the following: numerical analysis of simple multi-skill call center…

Mobile Telephony in Emerging Markets: The Importance of Multi-Simming Customers

2015

Rapidly increasing sales of multi-SIM phones, mobile penetration rates above 100% and reported customer behavior all point to the fact that a signicant share of mobile customers in emerging markets tend to use more than one SIM card. A primary motive for this is to avoid making expensive o-net calls. We add a segment of exible prepaid customers, who choose to "multi-sim" in equilibrium, to the seminal model of competing telephone networks a la Laont,

Remote Patient Monitoring Within a Future 5G Infrastructure

2010

Published version of an article from the journal: Wireless Personal Communications. The original publication is available at Spingerlink. http://dx.doi.org/10.1007/s11277-010-0078-5 Systems of wearable or implantable medical devices (IMD), sensor systems for monitoring and transmitting physiological recorded signals, will in future health care services be used for purposes of remote monitoring. Today, there exist several constraints, probably preventing the adoption of such services in clinical routine work. Within a future 5G infrastructure, new possibilities will be available due to improved addressing solutions and extended security services in addition to higher bandwidth in the wireles…

An innovative approach towards E-health in development of tele auscultation system for heart using GSM mobile communication technology

2013

Health is one of the major issues for normal existence of human life and it is a global agenda to increase the health care facilities for the peoples who don't have an immediate access to these facilities and are living in rural and undeveloped areas. From the beginning of twenty first century field of E-health has been developed rapidly to encounter these problems properly. The healthcare infrastructure gaining betterment day by day under the shadow of E-health technologies, where using mobile phones are becoming an efficient tool in monitoring and transmitting different physiological signals. Cardiac sound is an initiative physiological parameter that is helpful for diagnosing changes in …

A novel teletraffic-based power saving scheme for cellular networks with microcells

2011

As the number of network components increases to meet the explosion of mobile devices, power conservation has become an important strategy for network operators. In this paper, we propose a novel teletraffic-based approach to save power consumption of a three-cell microcellular network. When the traffic load in the middle cell is lower than certain threshold, the cell can be switched-off and its users will be covered by increasing the transmission power of one sector antenna in each of the two neighboring cells. Numerical results demonstrate that at a moderate cost of increased antenna transmission power of the two sectors, significant amount of network power can be saved for the whole netw…

Building a research prototype to provide pervasive services in hospitals

2008

Research into the nature of pervasive computing has now been around for more than a decade. Nowadays pervasive applications exploit mobile wireless communication technologies to interconnect computing devices along with various sensing technologies, setting up a new kind of intelligent environment where applications can transparently search and use services without userspsila intervention. However, there are few examples of real world deployment of pervasive computing moving out from academic laboratories into our everyday life. We present BlueHospital - a research prototype that provides context-aware information and location based services to clinicians in hospitalspsila recovery wards. T…

How value and trust influence loyalty in wireless telecommunications industry

2012

Despite making significant investments in enhancing the customer service experience, long-term customer loyalty remains an elusive dream for many service providers. Particularly in the telecommunications industry, switching providers even from within continuous contract relationships is easy and companies struggle to retain their customers. Trust and value are considered cornerstones of long-term relationships, so it is perhaps surprising that previous research on how relationship age and usage level actually affect value, trust and loyalty is inconclusive. The current research is set in the telecommunications services field and draws on a large-scale survey undertaken in Finland. The findi…
