How Conversations Change Over Time in Face-to-Face and Video-Mediated Communication

An experiment was conducted to examine how communication patterns and task performance differ as a function of the group’s communication environment and how these processes change over time. In a longitudinal design, three-person groups had to select and argue the correct answer out of a set of three alternatives for ten questions. Compared with...

Network-aware support for mobile distributed teams

An experiment evaluated network-aware support to increase understanding of the factors that are important for successful teamwork in mobile geographically dispersed teams of first responders. Participants performed a simulated search and rescue team task and were equipped with a digitized map and realtime situation updates on the location of...

Effects of time pressure and communication environment on team processes and outcomes in dyadic planning

An experiment compared dyadic performance in a radio communication and a more sophisticated communication environment to face-to-face (FtF) meetings. Thirty-six dyads, working under low or high time-pressure conditions, needed to combine information and to produce a written plan. Teams working in the sophisticated communication environment...

Virtuele teams erg efficient

Distributed mobile teams: Effects of connectivity and map orientation on teamwork

Fielded first responders are currently being equipped with support tools to improve their performance and safety. Novel information technology provides opportunities for improvement of task efficiency and situation awareness, but people can get in trouble when data networks fail. In this paper, we examine the effect of glitches in the data...

Costs and benefits of virtual teams

Internationalization and globalization are expanding. Many companies work with departments that are remote, or act in networks. Several factors, like unproductive travel time, jet lag, safety, and travel expenses, force to look for alternative for face-to-face meetings. TNO has reviewed the literature on virtual teams from the perspective of...

Overcoming distance in virtual teams: Effects of communication media, experience, and time pressure on distributed teamwork

Een virtueel team is een team waarvan de leden elkaar niet of zelden in levenden lijve ontmoeten, bijvoorbeeld omdat de teamleden verschillende werktijden hebben of op verschillende vestigingen van een organisatie werken. Anders dan reguliere teams zijn virtuele teams in grote mate afhankelijk van informatie- en communicatietechnologie. Een...

Effects of distributed teamwork and time pressure on collaborative planning quality

Distributed teamwork is not without its difficulties. The detrimental aspects of geographical dispersion of team members on effective teamwork are often invoked to justify reluctance 'to go virtual', despite the fact that for some tasks, and under some conditions, distributed environments may be as good as, or perhaps even better than, meeting...

A PC-Based virtual environment for training team decision-making in high-risk situations

Live team training of firefighters has several disadvantages. Firstly, it is costly because many team members and training staff are involved. Secondly, not all team members have the same competency level, and some individuals may just not be ready to train in a team context. Thirdly, live training in high-risk situations is difficult and...

Ergonomics, anthropometry, and human engineering

Het hoofdstuk geeft een overzicht hoe ergonomische testen kunnen worden uitgevoerd, met behulp van mock-ups of met behulp van digitale media zoals mensmodellen en virtuele omgevings (VE) technieken

The effects of proprioceptive and visual feedback on geographical

To effectively use a Virtual Environment (VE) for applications such as training and design evaluation, a good sense of orientation is needed in the VE. "Natural" human geographical orientation, when moving around in the world, relies on visual as well as proprioceptive feedback. However, the present navigation metaphors that are used to move...

Het praktisch gebruik van virtuele omgevingen voor ergonomische studies

De term Virtual Reality is misleidend. Met name het woord Reality suggereert dat men door high-tech 3D visualisatietechnieken computer gegenereerde omgevingen als realistisch kan ervaren. Niets is minder waar. Allereerst kon de synthetische wereld alleen gezien en soms gehoord worden, maar wordt deze niet gevoeld (aanraking, wind, temperatuur)...
