Custom ring tones for cellular phones have become extremely popular over the past several years, allowing users to customize their mobile computing experience, expressing their personality or enjoying their favorite tune. In the ring tone selection process, a user generally searches or browses for a ring tone by title in one of several ring tone databases and then purchases his selection. Resea...

Recently Mobile Learning (M-Learning) has attracted much attention. Due to advantages of SMS (Short Messaging Service) on mobile phones we present a safe and protected method for taking multiple-choice quizzes by using the SMS on mobile phones in this paper. In this method questions of quiz are sent to students along with their answers through some SMS messages. The students will receive their ...

The emergence of pervasive and mobile computing has drawn research attention to integrated mobile Grid systems. These new hybrid Grids consist of a typical SOA backbone extended to include mobile and small scale devices such as personal digital assistants, smart-phones, multimedia devices, and intelligent sensors. In a fully integrated model, mobile devices are able to act both as consumers and...

The emergence of pervasive and mobile computing has drawn research attention to integrated mobile Grid systems. Such systems consist of a typical SOA backbone extended to include mobile and small scale devices (Personal Digital Assistants, smart-phones, multimedia devices, sensors and more). In a fully integrated model, mobile devices are able to act both as consumers and providers to open up a...

Currently, it is possible to develop a collaborative application running on a collection of heterogeneous, possibly mobile, devices, each potentially hosting data stores, using existing middleware technologies such as JXTA, BREW, compact .NET and J2ME. However, they require too many ad-hoc techniques as well as cumbersome and time-consuming programming. Our System on Mobile Devices (SyD) middle...

TheWireless World Research Forum (WWRF) has identified ambient-awareness and device diversity as two key properties of applications and services in future mobile systems [1]. According to the WWRF, emerging applications for mobile devices will be adaptive, personalized, and context-aware. Ambient-awareness in particular is a crucial issue in indoor applications. Indeed, these applications need ...

Mobile tourist guides are increasingly useful once the visitors are in the archaeological sites. They are capable of providing huge amount of information about the sites. As it is easily understood, the selection of such information is a task that must be conducted by cultural institutions. Therefore, this paper aims at simplifying the provision of useful multimedia information in a user-friend...

Knowledge Elicitation (KE) methods are an integral part of Human Computer Interaction (HCI) practices. They are a key aspect to the synthesis of psychology empirical methods with requirements engineering, User Centred Design (UCD) and user evaluations. Examples of these methods include prototyping, focus groups, interviews, surveys and direct video observation. The MIKE project (Mobile Interact...

In an economic environment more global each day, a high percent of the employees in a company spend the most part of their work time outside their offices or even outside their countries. Advances in portable devices design and arrival of communication networks capable to transmitting such data allow these nomadic employees to fulfil their tasks with the only help of a mobile phone or a PDA. Ho...

Outdoor navigation of visually impaired people most often is based on data from the GPS maps and Geographic Information Systems (GIS). Such systems cannot be used for navigation in the regions where there are not any GPS maps or the maps are not sufficiently precise and detailed. This article describes an algorithm for real-time GPS track simplification. The test results show that the proposed ...
