Motion gestures have been proposed as an interaction paradigm for pairing, and sharing data between, mobile devices. They have also been used for interaction with large screens such as semi-public displays where a mobile phone can be used as a form of remote control in an eyes-free manner. Yet, so far, little attention has been paid to their potential use in cross-device web applications. We th...

The aim of this paper is to compare three different text editing interfaces for Digital Terrestrial Television. The study shows a significant relationship between users’ level of experience in text editing using mobile phone and their favourite interface. Moreover, the analysis demonstrates that there is no relationship between users’ level of experience and the editing problems they encountered.

In recent years the amount of scientific papers published on the topic of mobile applications has significantly increased. However, few researchers test their assumptions and solutions in industry. This thesis aims to provide an overview of what current scientific literature considers problems and potential solutions in mobile application testing, and compare it to opinions of industry professi...

With the prevalence of mobile devices and platforms used throughout the world and the increasing number of organizations with mobile versions of their web sites, it is essential that those applications and sites are accessible, usable and flexible. This project involved the inclusive development and iterative evaluation of a platform-independent, web-based learning app. Usability testing with s...

The expansion of the web has reached outrageous proportions with the number of web communities existing and the number of those being created daily increasing dramatically. To parallel this phenomenon is the trend nowadays of mobile phone services. One of the most representative is the case of Greece, where in a period of five years about five million people subscribed for a telephone number fo...

Recent advances in mobile computing have spawned a very heterogeneous environment of mobile devices. Those devices have different capabilities in providing mobile services to the user, implying the challenge of considering heterogeneous devices during mobile service development. This especially encompasses the task of adapting the content, which a mobile service provides to a specific mobile de...

This paper presents the TOTEM framework for supporting the content creation and structuring for location-based games. Shapes (templates), Marbles (instances) and Pebbles (raw data) build the conceptual background while two integrated tools support the overall workflow: TOTEM.Designer, a web-application that allows for desktop-based authoring and TOTEM.Scout, a mobile app that allows for in-situ...

Time-based coordinated checkpointing protocols are well suited for mobile computing systems because no explicit coordination message is needed while the advantages of coordinated checkpointing are kept. However, without coordination, every process has to take a checkpoint during a checkpointing process. In this paper, an efficient time-based coordinated checkpointing protocol for mobile computi...

Current media for disseminating traffic conditions to motorists are often infrequent and lack sufficient detail. Mingle, a mobile application for visualizing historic traffic information in conjunction with current conditions, was developed to alert users to problematic areas and allow them to make informed decisions with respect to altering their route. Mingle layers select traffic datasets on...
