Researchers seeking to develop complex statistical applications for mobile devices face a common set of difficult implementation issues. In this work, we discuss general solutions to the design challenges. We demonstrate the utility of the solutions for a free mobile application designed to provide power and sample size calculations for univariate, one-way analysis of variance (ANOVA), GLIMMPSE...

Falling is a serious danger to older adults that is usually only addressed after a person has fallen, when doctors administer clinical tests to determine the patient's risk of falling again. Having the technological capability of performing fall risk assessment tests with a smartphone, the authors set out to design a mobile application that would enable users to monitor their risk themselves an...

7 EDITORIAL Please cite this paper as: White, J. Going native (or not): Five questions to ask mobile application developers. Introduction I recently needed a new shovel. At the hardware store I was, as always, taken aback at the range of options available to me, and the range of prices I could pay. Hardware store regulars will know that this is true of everything from lawnmowers to screwdrivers...

BACKGROUND Suicide is a major public health issue and has large impact on the lives of many people. Innovative technologies such as smartphones could create new possibilities for suicide prevention, such as helping to overcome the barriers and stigma on help seeking in case of suicidal ideation. Due to their omnipresence, smartphone apps can offer suicide prevention tools very fast, they are ea...

Practical hydrogen storage for mobile applications requires materials that exhibit high hydrogen densities, low decomposition temperatures, and fast kinetics for absorption and desorption. Unfortunately, no reversible materials are currently known that possess all of these attributes. Here we present an overview of our recent efforts aimed at developing a first-principles computational approach...

BACKGROUND Interest in mobile apps that support long-term conditions such as asthma is matched by recognition of the importance of the quality and safety of apps intended for patient use. We assessed how changes over a 2-year period affected the clinical suitability of apps providing self-management information and tools for people with asthma by updating a review first performed in 2011. MET...

The Personal Server is a small, lightweight, and easy-to-use device that supports personal mobile applications. Instead of relying on a small mobile display, the Personal Server enables seamless interaction with situated displays in the nearby environment. The current prototype is supported by emerging storage, processing, and communication technologies. Because it is carried by the user and do...

abstract Evaluating mobile applications and devices is particularly challenging given the variability of users, uses, and environments involved. This chapter introduces usability evaluation methods (UEMs) for mobile applications. Over the past decades various usability evaluation methods have been developed and implemented to improve and assure easy-to-use user interfaces and systems. Since mos...

We believe that the trend towards cooperative applications is interwoven with trends towards both multimedia and mobile computing and with the trend towards integrated software solutions. This means that the design and development of cooperative applications should be treated in a larger context: the design and development of “customized enterprise-wide cooperative media-integrated (i.e. multim...
