Artistic and musical applications of Internet search technologies: prospects and a case study

This article explores the idea of Internet search as a technology to underpin artistic creation. Concepts of interactivity in art and music are explored, and then an overview of different types of Internet-based art is presented. A number of different ways in which Internet search have the potential to underpin artistic and musical activity are then discussed, with ideas such as the idea of a collective readymade and aesthetics of mass and unexpected connections are used to give this discussion a theoretical basis. Finally, a case study is given, in which the author discusses one of his own multimedia artworks that makes substantial use of Internet search.     

From broadcast television to Internet audio/video: techniques and tools for VCR‐style interactivity

One of the new applications evolving in the Internet is streaming audio/video. A major reason for its growing popularity is interest in the compelling new services that become possible. Prototype services are being developed which are new to the Internet but offer the same look, feel, and functionality that have traditionally only been found in services delivered via other communication medium, e.g. broadcast television. In addition, the Internet is evolving to offer ‘value‐added’ services, like streaming audio/video with VCR‐style interactivity and embedded hyperlinks. We are poised both on seeing the development of new paradigms for interacting with audio/video, and on seeing the merging of broadcast television and Internet‐based broadcasts. Before this process can be considered successful, a number of technical challenges, derived from the various ways in which content is physically delivered, must be solved. In this paper, we focus on the value‐added service of VCR interactivity. VCR interactivity has long been a challenge for both broadcast television and streamed Internet audio/video. The challenge is how to provide individualized playout for content being streamed to a large group of users using one‐to‐many delivery. While some new companies are starting to offer devices which provide this kind of service for broadcast television, there are still numerous technical challenges for the Internet‐based version of a similar service. This paper has a three‐fold objective. First, we describe the types of services available in the traditional broadcast infrastructure and compare these to the types of services that are deployed or possible in Internet‐based services. Second, we describe our attempts to implement some of the more challenging and novel service types. In particular, we examine client‐based control of programs streamed over the Internet to tens, thousands, or even millions of users. Finally, we discuss the impact of these services on the protocols and applications used to support Internet‐based, multi‐party conferencing. Copyright © 2001 John Wiley & Sons, Ltd.     

梁平法施工图识读的交互式CAI课件开发

依据某典型框架梁的平法施工图,以及据此绘制的梁纵剖面钢筋分离图、梁横截面图,通过构建反映线对象几何形状的自有坐标系和控制点矩阵,并借助坐标变换完成了在全局坐标系中三维显示框架梁模型中线对象的数据准备,最后使用MATLAB的GUIDE实现了框架梁三维模型的控制显示,证实了交互式CAI课件开发方法的可行性。     

基于OMA标准的智能交互式多屏解决方案

目前的网络多媒体业务越来越强调交互,强调用户参与,而多屏业务（手机屏,电脑屏,IPTV电视屏）由于跨越3种异构网络（移动通信网、有线以太网、广电网/电信IPTV网）,涉及3种终端,交互在多屏业务中的作用就更加突出了。因此,我们必须给出一套跨越3种异构网络进行交互的方案,能够使用户尽情享受眩彩多屏业务。OMA国际标准中已经规定了交互机制以及异构网络下的设备管理机制,本文就利用OMA国际标准中的交互机制以及设备管理机制构建了一套智能交互式多屏解决方案。
