The paper describes a multiple platform-based approach to creating a bus route information system for mobile devices. The system is context aware: users only need to tell the system (in natural language) where they wish to go, and the system takes care of the rest. The users are presented wi...

With the constant increase in smartphone sales, integrated sensors and map navigation have now become available to the average user. This allows for mobile applications to use context-awareness to provide more relevant information. An interesting use-case for such applications is a rout...

The Web is truly becoming ubiquitous now that more and more people own a mobile device with a web browser. Many users want to exploit the fact that they can be online practically 24 hours a day, and they have ideas about what services they need. However, most of the users are not proficient in any p...

With mobile devices being an integral part of the daily life of millions of users having little or no ICT knowledge, mobile services are being developed to save them from difficult or tedious tasks without compromising their needs. Starting with a number of real life scenarios we have been working t...

Despite advances in mobile computing technologies,end-user development has mainly focused on desktop applications. Fundamentally contrasting desktop applications, mobile applications should satisfy the changing needs and tasks of the users on the move, and usually have a strong affinity with the phy...

Intelligent objects and devices are becoming part of the environment where people live. The more mobile and pervasive computing becomes, the greater opportunity users potentially have to customize the computing activities that take place around them. For some people the availability of devices and s...

This publication presents a tool chain for end-users service composition. The tool chain includes two tools: The EasyComposer is a graphical service creation environment aimed for the end-users. The EasyDroid is a service execution environment capable of executing EasyComposer composite services on ...

Social Networks, Mobile Internet and Location-Awareness nowadays can be combined into a new type of ubiquitous environments (“Future Internet”, location-aware social networks), where security, privacy and trust are very important problems, especially for end-users. These are relatively new research ...

This paper presents a graphical tool for end-user service composition. The tool, EasyComposer, has been developed within the context of a research project addressing end-user service composition in ubiquitous service environments. The EasyComposer is a simple composition tool that the end user can u...

A major challenge of dynamic composition is to find ways to model components and analyze their composition in order to guaran- tee that the composition is free from interaction errors and deadlocks. Existing techniques for validation typically require expert knowledge in formal modelling and reasoni...

Despite advances in software engineering methods and tools, understanding what software components do and ensuring that they work well together remains difficult. This is chiefly due to the lack of support for specifying component interfaces and software compositions formally. Due to these shortcomi...

The research problem is to create method for run-time composition, formal modeling (specification, validation) with immediate automated implementing of new run-time changes and dynamicity properties of distributed software, which realize collaborative services in ubiquitous environments. ”РАДУГА” i...

This publication discusses one of the project case scenarios, the City Guide scenario, and describes an initial experiment done in order to develop and validate the user interface of a service composition tool for creating mobile tourist services in a city environment.
