This paper presents preliminary findings on teenagers’ use of instant messaging (IM) as an example of an Internet technology. The results are quantitative, being drawn from the information held in users’ IM log files. The current purpose is to validate the proposed data collection method, and to explore the analytical possibilities it presents. This is done through the discussion of a number of graphical representations generated from the data.

This paper draws on macro and micro theories of user experience in order to focus on the use of Apple’s iPod. It begins by outlining macro theories from Cultural Studies on the process of product articulation illustrated with reference to the Sony Walkman. The paper then turns to more recent theories of user experience generated in HCI over the past five years that offer micro accounts of experience and the ways in which a product interaction is shaped by particular people in particular contexts. These theoretical approaches are brought together in an account of the Apple iPod using pastiche scenarios that draw on popular fiction as a resource for reflecting on design. The account focuses on broad developments in the recording industry and also instances of individual iPod use

Why do some technologies successfully assimilate into the home and others fail? The physical layout could be one factor but another more important factor could be the social aspects of the home space. Also, once a technology enters the home does it impact on the social life of that home? Some manufacturers in the past have adapted their devices so that they assimilate more clearly into the home, however, until quite recently this was something that was not done by manufacturers of PCs. The impact that this design decision has had on the acceptance of the home computer is the topic of this paper.

Mobile ad-hoc networks are the networks that can be formed with the mutual coordination of two or more mobile devices without the intervention of any fixed infrastructure. Our future homes and Industrial environments are likely to be based on the networks which are easy to deploy with minimal installation and maintenance cost. Mobile ad-hoc networks have strong potential to fulfil the requirements of future computing. Where, on one hand mobile ad-hoc networks are able to give us a networking environment where we can form network on our convenience without involving much complexities. The other side shows that there are number of issues in this area which require satisfactorily solutions before we will be able to use mobile ad-hoc networks at a wider scale i.e. home, business, education and other environments. Routing can be seen as one of the important aspect of any networking environment. It is an unresolved issue in mobile ad-hoc networks. Work is going on since over a decade to invent an efficient routing mechanism for mobile ad-hoc networks. Numbers of different techniques and algorithm have been proposed. However, most of these solutions have certain limitation which makes them unable to operate in all environments. Moreover, very less attention has been given to obtain analytical results of these algorithms in a real environment. Our research shows, that most of the existing issues in mobile ad-hoc networks are interrelated with the routing mechanism of mobile ad hoc networks. On the basis of carried out research, we have also concluded that most of the proposed protocols, if good in addressing some issues besides routing, they are not very impressive in handling others. As deployment of mobile ad hoc networks in future home environment depend very much on the invention of a successful routing solution. We have proposed a novel algorithm ‘mobile ad-hoc on demand data delivery protocol (MAODDP)’ as a routing solution for mobile ad hoc networks. One of the important features of MAODDP is the fast communication by establishing route and delivering data simultaneously at the same time. MAODDP follows an intermediate approach in between tables driven and on-demand routing protocols and can be used to save bandwidth and battery life of the participating nodes of mobile ad hoc networks. In this paper, we will discuss in details about various aspects of mobile ad hoc on demand data delivery protocol and its importance in our future computing environment.

In the last decade, Assistive Technology researchers have studied and developed accessible and adaptable environments intended to enhance the autonomy and the quality of life of the people with disabilities and elderly people. Their efforts, technologically rooted in the Ubiquitous Computing technologies, are firmly supported by the Ambient Intelligence concept. In the assistive scenario the main problem that researchers have to face is the integration of diverse local and remote services that were previously provided through different network technologies. In this paper we identify the main issues that may influence design decisions regarding the integration of -and the interaction among- different subsystems in the context of assistive technologies.
