3D and multimedia on the information superhighway.

YesWhat has generated the unprecedented fascination with the Internet? What future lies ahead for computing as the Internet and its associated infrastructure expand? Will the network be able to cope with rising demands for carrying capacity and response speed? Will it change the way scientists, designers, artists, computer professionals, and home users work in the future? These are some of the wideranging questions being asked about the Internet and World Wide Web

Peripatetic electronic teachers in higher education

This paper explores the idea of information and communications technology providing a medium enabling higher education teachers to act as freelance agents. The notion of a ‘Peripatetic Electronic Teacher’ (PET) is introduced to encapsulate this idea. PETs would exist as multiple telepresences (pedagogical, professional, managerial and commercial) in PET‐worlds; global networked environments which support advanced multimedia features. The central defining rationale of a pedagogical presence is described in detail and some implications for the adoption of the PET‐world paradigm are discussed. The ideas described in this paper were developed by the author during a recently completed Short‐Term British Telecom Research Fellowship, based at the BT Adastral Park

Delivery of broadband services to SubSaharan Africa via Nigerian communications satellite

Africa is the least wired continent in the world in terms of robust telecommunications infrastructure and systems to cater for its more than one billion people. African nations are mostly still in the early stages of Information Communications Technology (ICT) development as verified by the relatively low ICT Development Index (IDI) values of all countries in the African region. In developing nations, mobile broadband subscriptions and penetration between 2000-2009 was increasingly more popular than fixed broadband subscriptions. To achieve the goal of universal access, with rapid implementation of ICT infrastructure to complement the sparsely distributed terrestrial networks in the hinterlands and leveraging the adequate submarine cables along the African coastline, African nations and their stakeholders are promoting and implementing Communication Satellite systems, particularly in Nigeria, to help bridge the digital hiatus. This paper examines the effectiveness of communication satellites in delivering broadband-based services

Multimedia broadcast and internet satellite system design and user trial results

The EU funded project, System for Advanced Multimedia Broadcast and IT Services (SAMBITS), has created an enhanced and synchronised, multimedia terminal for merging satellite broadcast and internet telecommunication services in a way that efficiently combines the large bandwidth of the broadcast channel and the interactivity of the internet. This paper proposes a novel broadcast and internet service concept, illustrates this concept with two service scenarios and develops a system architecture to demonstrate the range of key benefits provided by these new technologies. It then describes the interactive multimedia terminal that was used for consuming this new service concept. Finally, the results of the user trials on the terminal are presented and discussed

Mapping cyberspace: visualising, analysing and exploring virtual worlds

In the past years, with the development of computer networks such as the Internet and world wide web (WWW), cyberspace has been increasingly studied by researchers in various disciplines such as computer sciences, sociology, geography, and cartography as well. Cyberspace is mainly rooted in two computer technologies: network and virtual reality. Cybermaps, as special maps for cyberspace, have been used as a tool for understanding various aspects of cyberspace. As recognised, cyberspace as a virtual space can be distinguished from the earth we live on in many ways. Because of these distinctions, mapping it implies a big challenge for cartographers with their long tradition of mapping things in clear ways. This paper, by comparing it to traditional maps, addresses various cybermap issues such as visualising, analysing and exploring cyberspace from different aspects

A Brief Defense of Mass Market Software License Agreements

In the rapidly changing world of personal computer software, the end user license agreement ( EULA ) has endured. The EULA is a familiar component of most personal computer software transactions. Many commentators, however, have maligned the practice of standard form software licensing. A survey of the literature on the subject might lead one to conclude that there are only critics--and no proponents--of EULAs. Despite the din of criticism, EULAs continue to be widely usedby almost every mass-market software publisher, even though the cost of doing so is significant. This Article explains the value of EULAs for both software publishers and users, and why EULAs will be even more valuable for distributing the rich variety of information products available on the information superhighway. Given the benefits provided by EULAs, courts and legislatures should seek to validate their use. This perspective is particularly significant in light of the National Conference of Commissionerson Uniform State Laws and the American Law Institute\u27s efforts to draft an article of the Uniform Commercial Code which addresses software licensing (currently referred to as U.C.C.Article 2B ). This Article first introduces the various forms EULAs take, andthen explains the main advantages of EULAs. It argues that EULAs provide valuable information to end users, and that EULAs permit software publishers to offer the wide variety of rights that are associated with the features of today\u27s software products. This Article further explains why the ability to offer a variety of rights in a EULA will be even more important for the information products of the future. This Article concludes by proposing methods for improving how EULAs are used in the software contracting process
