TeleAdvisor is a novel solution designed to support remote assistance tasks in many real-world scenarios. It consists of a video camera and a small projector mounted at the end of a tele-operated robotic arm. This enables a remote helper to view and interact with the workers' workspace, while controlling the point of view. It also provides the worker with a… (More)
In the BEAMING project we have been extending the scope of collaborative mixed reality to include the representation of users in multiple modalities, including augmented reality, situated displays and robots. A single user (a visitor) uses a high-end virtual reality system (the transporter) to be virtually teleported to a real remote location (the… (More)
The (Na,K)-pump develops and maintains ionic gradients that are of fundamental importance for proper function of most animal cells. These gradients are utilized in the form of ionic leak pathways by a number of special and general cell processes (e.g., nerve conduction, nutrient transport, pH regulation). As the sodium gradient in particular energizes many… (More)
—Intelligent Environments most commonly take a physical form such as homes, offices, hotels, restaurants, shops, that are equipped with advanced networked computer based systems, which enable better or new lifestyles for people. However, Intelligent Environments can also take the form of virtual online spaces such as SecondLife, which can both mimic the… (More)
In this paper we investigate user performance and user behavior, related to the issue of who controls the point of view in a remote assistance scenario. We describe an experiment that examined users completing two different tasks with the aid of a remote gesturing device under two conditions: when control of the camera and gesturing point of view was in the… (More)
We present some of the issues in the design of a mobile hypermedia system with display on PDAs.
and the participants at the WEA International 1997 Annual Conference for helpful comments. I am especially grateful to Cheng-Zhong Qin for his advice. Any errors in this paper are my sole responsibility. Abstract: Sovereign states often borrow to finance their budgets in the modern era; in the medieval period kings had similar financing needs. Both types of… (More)
When do states defend their reputations? States sometimes pay heavy costs to protect their reputations, but other times willingly take actions that could tarnish them. What accounts for the difference? This paper investigates the sources of reputation-building in the context of coercive diplomacy. It argues that fears about the future drive… (More)
