The Internet is growing ever more mobile – meaning, that an ever greater proportion of Internet devices are mobile devices. This trend necessitates new designs and will produce new and even unpredictable conceptions about the very nature of the Internet and, more fundamentally, the nature of social interaction. The engineering response to growing mobility and complexity is difficult to predict. This chapter summarizes the past and the present ways of dealing with mobility, and uses that as context for trying to understand what needs to be done for the future. Central to the conception of future mobility is the notion of “always available” and highly interactive applications. Part of providing acceptable service in that conception of the mobile Internet will require better ways to manage handovers as the device moves around the Internet, and ways to better either hide or make available a person's identity depending on who is asking.

The proliferation of the use of Internet has led to speculations that the interactive possibilities offered by this technology will lead to a democratisation of political communication. It is argued that citizens will enjoy more opportunities to discuss polities with other citizens and to express their opinions toward the political system. In this casestudy, we examine the political  use of internet at the time of the Belgian local elections of 8 October 2000. Building on the coding scheme developed by Pippa Norris, we distinguish interactive and institutional communication through the Internet, in which we expect that interactive communication has a democratie potential, while the institutional communication shows atendency to strengthen existing power relations. The data show that during this election campaign the Internet has been used mainlyfor institutional purposes, not for interactive applications. Therefore our conclusion is that, especially in small languageareas, the democratic potential of Internet remains limited.

The demand for online services is increasing. Services that would require a long time to understand, use and master are becoming as transparent as possible to the users, that tend to focus only on the final goals. Combined with the advantages of the unmanned vehicles (UV), from the unmanned factor to the reduced size and costs, we found an opportunity to bring to users a wide variety of services supported by UV, through the Internet of Unmanned Vehicles (IoUV). Current solutions were analyzed and we discussed scalability and genericity as the principal concerns. Then, we proposed a solution that combines several services and UVs, available from anywhere at any time, from a cloud platform. The solution considers a cloud distributed architecture, composed by users, services, vehicles and a platform, interconnected through the Internet. Each vehicle provides to the platform an abstract and generic interface for the essential commands. Therefore, this modular design makes easier the creation of new services and the reuse of the different vehicles. To confirm the feasibility of the solution we implemented a prototype considering a cloud-hosted platform and the integration of custom-built small-sized cars, a custom-built quadcopter, and a commercial Vertical Take-Off and Landing (VTOL) aircraft. To validate the prototype and the vehicles’ remote control, we created several services accessible via a web browser and controlled through a computer keyboard. We tested the solution in a local network, remote networks and mobile networks (i.e., 3G and Long-Term Evolution (LTE)) and proved the benefits of decentralizing the communications into multiple point-to-point links for the remote control. Consequently, the solution can provide scalable UV-based services, with low technical effort, for anyone at anytime and anywhere.

Music notation modeling is entering the new multimedia Internet age. In this era new interactive applications are appearing on the market, such as software tools for music tuition and distance learning, for showing historical perspective of music pieces, for musical content fruition in libraries, etc. For these innovative applications several aspects have to be integrated with the model of music notation and several new functionalities have to be implemented, such as automatic formatting, music notation navigation, synchronization of music notation with real audio, etc. In this chapter, the WEDELMUSIC XML format for multimedia music applications of music notation is presented. It includes a music notation format in XML and a format for modeling multimedia element, their relationships and synchronization with a support for digital right management (DRM). In addition, a comparison of this new model with the most important and emerging models is reported. The taxonomy used can be useful for assessing and comparing suitability of music notation models and format for their adoption in new emerging applications and for their usage in classical music editors.

Background: Exploring patients’ computer and internet use, their expectations and attitudes is mandatory for successful introduction of interactive online health-care applications in Angiology. Patients and methods: We included 165 outpatients suffering from peripheral arterial disease (PAD; n = 62) and chronic venous and / or lymphatic disease (CVLD; n = 103) in a cross-sectional-study. Patients answered a paper-based questionnaire. Results: Patients were predominantly female (54.5 %). 142 (86.1 %) reported regular computer use for 9.7 ± 5.8 years and 134 (81.2 %) used the internet for 6.2 ± 3.6 years. CVLD-patients and internet-user were younger and higher educated, resulting in a significant difference in computer and internet use between the disease groups (p < 0.01 for both). Time spent online summed up to 4.3 ± 2.2 days per week and 1.44 ± 1.2 hours per day for all internet users without significant differences between the groups. The topics retrieved from the internet covered a wide spectrum and searches for health information were mentioned by 41.2 %. Although confidence in the internet (3.3 ± 1.1 on a 1-6 Likert scale) and reliability in information retrieved from the internet (3.1 ± 1.1) were relatively low, health-related issues were of high actual and future interest. 42.8 % of the patients were even interested in interactive applications like health educational programs, 37.4 % in self-reported assessments and outcome questionnaires and 26.9 % in chatforums; 50 % demanded access to their medical data on an Internetserver. Compared to older participants those < 50 yrs. used the internet more often for shopping, chatting, and e-mailing, but not for health information retrieval and interactive applications. Conclusions: Computers are commonly used and the internet has been adopted as an important source of information by patients suffering from PAD and CVLD. Besides, the internet offers great potentials and new opportunities for interactive disease (self-)management in angiology. To increase confidence and reliability in the medium a careful introduction and evaluation of these new online applications is mandatory.
