In spoken dialogue applications dialogue management has conventionally been realized with a single monolithic dialogue manager implementing a comprehensive dialogue control model. We present a highly distributed system structure that enables the integration of different dialogue control approaches to handle spoken dialogues. With this structure it is possible to integrate multiple dialogue control models into a single working application in a flexible fashion. The main principle is that all the processing is distributed into many compact agents that focus on single tasks. The agents process the information independently and share all the information via shared information storage. We present the principles that enable such distribution. In addition, a multilingual example application, AthosMail, is presented.

Evaluating distributed CSCW applications is a difficult endeavor. Frameworks and methodologies for structuring this type of evaluation have become a central concern for CSCW researchers. In this paper we describe the problems involved in evaluating remote collaborations, and we review some of the more prominent conceptual frameworks of group interaction that have driven CSCW evaluation in the past. A multifaceted evaluation framework is presented that approaches the problem from the relationships underlying joint awareness, communication, collaboration, coordination, and work coupling. Finally, recommendations for carrying out multifaceted evaluations of remote interaction are provided. Copyright 2004 ACM.

The present aim was to study a new technique for human—computerinteraction. It combined the use of two modalities, voluntary gaze direction and voluntary facial muscle activation for object pointing and selection. F...

Many failures in long-term collaboration occur because of a lack of activity awareness. Activity awareness is a broad concept that involves awareness of synchronous and asynchronous interactions over extended time periods. We describe a procedure to evaluate activity awareness and collaborative activities in a controlled setting. The activities used are modeled on real-world collaborations documented earlier in a field study. We developed an experimental method to study these activity awareness problems in the laboratory. Participants worked on a simulated long-term project in the laboratory over multiple experimental sessions with a confederate, who partially scripted activities and probes. We present evidence showing that this method represents a valid model of real collaboration, based on participants' active engagement, lively negotiation, and awareness difficulties. We found that having the ability to define, reproduce, and systematically manipulate collaborative situations allowed us to assess the effect of realistic conditions on activity awareness in remote collaboration.

This paper presents work aimed at supporting the design of temporal aspects of socio-technical systems. Time design is a framework for (a) analysing and representing temporal properties of the work domain, (b) generating design options that support timely, flexible and dependable function servicing, and (c) providing knowledge about the characteristics and biases of human temporal control behaviour. In support of the latter end, two microworld experiments that investigated temporal control decisions in a supervisory control task are presented. These experiments manipulated event rate, the duration of event rate blocks, the availability of online and offline event rate information, and the accuracy of this information. The studies identified conditions where attention to temporal information decreased and the use of conservative temporal control strategies increased

Heuristic evaluation method comparison is important for developing new heuristic sets, to ensure effectiveness and utility. However, comparing different sets of heuristics requires a common baseline upon which a comparison can be made, usually some set of usability problems from a particular interface. This is often accomplished by having evaluators perform system evaluation to produce a set of usability problems for each method in question. A problem arises in that different methods produce different sets of problems, thus introducing validity concerns and ambiguity in resolution of disparate problem sets. We address this problem by illustrating a new comparison technique in which predetermined usability issues are presented to the evaluators up front, followed by assessment of thoroughness, reliability, and cost for the target methods. Comparison of method effectiveness is simplified, and validity concerns are ameliorated.
