Editorial Pointers

This month, two special sections explore how software agents independently and through their interaction in multiagent systems are transforming the Internet’s already tumultuous character and mission. Functioning through the medium of autonomous actions, agents and agent systems move out into the Net’s distributed, large-scale, dynamic structure on behalf of often-anonymous servers and human users scattered […]

Some U.S. elementary school computer workstations could put children at risk for developing poor postures and painful repetitive stress injuries, according to a Cornell University study. In the study, to be published in the May issue of the journal Computers in the Schools, researchers watched 95 elementary school children as they worked on computers in […]

Forum

I was surprised to see Jakob Nielsen’s conclusions about the state of Web usability and the need for UI standards (Jan. 1998, p. 65), and having just come to the opposite set of conclusions in my column "View Source: Lessons from the Web’s Massively Parallel Development" in ACM’s networker (Dec. 1998, p. 56), I’d like […]

Viewpoint: Focus Groups, Theory or the Kid in the Garage?

A few years ago, a group of heavyweight thinkers attempted to invent interactive TV. There were product managers, human factors engineers, usability specialists, and designers of every conceivable variety—graphic designers, broadcast designers, interaction designers, industrial designers, and sound designers. There were also creative directors, producers, film directors, creative agents, software engineers and computer scientists. Expert […]

Multiagent Systems on the Net

Over the last few years, the term "agents" has become popular, and consequently, much used and abused. Although several agent-based systems now exist on the network, most are essentially centralized on a single agent. However, the distributed, large-scale, dynamic nature of the Internet speaks to the need for open, flexible, and scalable solutions. This is […]

Multiagent Data Collection in Lycos

We proceed from a relatively weak notion of agency in cooperating software system components to describe the data collection activities of the Lycos Internet information retrieval services. The characteristics of agency of interest include autonomy, social ability, reactivity, and proactivity. The original and simple Lycos spiders, once implemented in Perl, have evolved into a true […]

Agents in Tank Battle Simulations

Networks of computers can be used to produce a digital virtual environment (DVE) where multiple participants can interact. This technology is extremely attractive to the military to provide training simulations. By the use of mock-up vehicles and high-fidelity visual systems, trainees get a window onto a virtual world populated by simulated vehicles interacting over a […]

Inside Risks: Bit-Rot Roulette

It’s obvious that our modern society is becoming immensely dependent on stored digital information, a trend that will only increase. Aspects of our culture that have routinely been preserved in one or another analog form are making transitions into the digital arena. Consumers who have little or no technical expertise are now using digital systems […]
