The following paper examines ongoing work on Wigglestick, a mobile way-finding service for the urban pedestrian. It enables users to tag media at specific spots, make their location visible to approved friends, and find their way to desired places. Its usage of the divining rod as a metaphor for the development of the mobile application has encouraged a minimal abstracted visualization approach...

Researchers studying daily life mobility patterns have recently shown that humans are typically highly predictable in their movements. However, no existing work has examined the boundaries of this predictability, where human behaviour transitions temporarily from routine patterns to highly unpredictable states. Yet, this is arguably one of the most interesting and critical states, where users m...

For understanding the heterogeneity of tinnitus, large samples are required. However, investigations on how samples recruited by different methods differ from each other are lacking. In the present study, three large samples each recruited by different means were compared: N = 5017 individuals registered at a self-help web platform for tinnitus (crowdsourcing platform Tinnitus Talk), N = 867 us...

BACKGROUND Mobile health (mHealth) is a growing field aimed at developing mobile information and communication technologies for healthcare. Adolescents are known for their ubiquitous use of mobile technologies in everyday life. However, the use of mHealth tools among adolescents is not well described. OBJECTIVE We examined the usability of four commonly used mobile devices (an iPhone, an Andr...

Current technology development in mobile computing and upcoming application stores enable an easy development and distribution of mobile applications. This leads to an increasing number of available applications and to the user’s problem of content discovery. Recommender systems aim at guiding users to relevant items. Currently, recommender systems that suggest mobile applications neglect that ...

The mobile phone market has beheld a rapid industrial development over the past few years. The swift growth of this latest computing platform has nearly outdone the software industrial processes adapted to mobile application development. Yet, there are still some defects and lack of research activities in development process of the mobile apps. There still remains some deficit in the developmen...

developing of mobile technologies in the field of health create a new branch of e-health called mobile-health. the goal of this study is evaluation of communications infrastructure for mobile-health. for this purpose, fuzzy analytic hierarchy process is used for modeling and ranking the criterions and applications. three main criteria in mobile communication network namely, data transmission, a...

Cloud computing infrastructure is increasingly used for distributed applications. Mobile learning applications deployed in the cloud are a new research direction. The applications require specific development approaches for effective and reliable communication. This paper proposes an interdisciplinary approach for design and development of mobile applications in the cloud. The approach includes...

Evaluating mobile applications to identify usability problems presents a unique set of challenges. Not only is it difficult to capture data on an application that is inherently mobile, but generating an authentic environment of use is also problematic. This paper compares two “traditional” user-based approaches to evaluate a mobile system: one laboratory-based and the other in the field. These ...

Can we predict which conversations are enjoyable without hearing the words that are spoken? A total of 36 participants used a mobile app, My Social Ties, which collected data about 473 conversations that the participants engaged in as they went about their daily lives. We tested whether conversational properties (conversation length, rate of turn taking, proportion of speaking time) and acousti...
