In this paper, we present an algorithm for the analysis of opportunistically collected mobile phone location data to estimate a population’s travel demand in terms of origins and destinations of individual trips. Aggregating the trips from millions individual mobile phone users in the Boston Metropolitan area, we show that the estimated Origin-Destination flows correlate well with the US Census...

This paper presents a novel acceptance model for scenarios in which people make use of mobile devices for leisure purposes. The use of mobile devices has such a dominant leisure component that user attitudes towards mobile adoption are strongly determined. Since hedonic aspects play a key role in mobile adoption, they are introduced through the constructs in the proposed Technology Acceptance M...

The smartphone revolution has brought ubiquitous, powerful, and connected sensing hardware to the masses. This holds great promise for a wide range of research fields. However, deployment of experiments onto a large set of mobile devices places technological, organizational, and sometimes financial burdens on researchers, making realworld experimental research cumbersome and difficult. We argue...

Introduction: There have been many studies conducted on the effects of mobile phones radiations on people’s health due to increasing number of mobile phones users. The present study aimed to investigate the effects of electromagnetic waves generated from 3G and 4G mobile phone radiations on student’s reaction time and short-term memory. <stro...

Background: Mobile phone is one of the most important necessary tools in today’s life which can threaten people’s health in some conditions. The present study was carried out to compare the effect of educational intervention by short message and pamphlet on the behavior of steel factory staff in Ardakan, Yazd province, Iran.Materials and Methods: The present study was experimentally carried out...

Use of optical imaging for medical and scientific applications requires accurate quantification of features such as object size, color, and brightness. High pixel density cameras available on modern mobile phones have made photography simple and convenient for consumer applications; however, the camera hardware and software that enables this simplicity can present a barrier to accurate quantifi...

BACKGROUND Epidemiologists and ecologists often collect data in the field and, on returning to their laboratory, enter their data into a database for further analysis. The recent introduction of mobile phones that utilise the open source Android operating system, and which include (among other features) both GPS and Google Maps, provide new opportunities for developing mobile phone applications...
