Abstract: Emotion has been found to influence humans’ cognitive information processing and decision-making (Schwarz, 2000). A state of sadness, for example, is accompanied by substantive information processing, with greater attention to detail, whereas people in a happier state tend to process information more heuristically. Mobile applications or services presenting information to users, especially those used primarily in emotionally laden contexts, could adapt information
presentation to users’ current emotional state to improve compliance. This paper reports the results of an 2x2 betweensubject survey experiment (N=91) with affective state (happy vs. sad) and information presentation style (heuristic vs.
substantive) as dimensions. The results confirm that participants in a sad affective state are more likely to comply with mobileagents’ advice when information is tailored to a substantive processing style. They base decisions on substantive
information and provide longer descriptions. In contrast, people in a happy affective state prefer heuristic information. These findings reinforce the importance of affect-sensitive adaptation, especially for mobileagents in potentially emotionally laden contexts.
Abstract: The proliferation of small mobile devices and wireless networks has resulted in an increasing demand to support the applications found in wired environments on mobile devices. In real time replication systems, such as collaborative systems, this trend gives some new problems to address. The properties of wireless networks are low bandwidth and high latency, which change dynamically over time. The risk of the network getting congested is therefore high with the result that the user will not receive the important information in time. Consequently there is a need to develop algorithms and methods for adaptive work environments and adaptive data distribution, to minimise the traffic load. An architecture based on multi- and mobile-agents is proposed as a solution. Personalized behaviour is included in a flexible and extensible system. A prototype of the architecture has been implemented in a crisis environment and was used for an evaluation. It is assumed that each individual in the field is equipped with a PDA that can communicate with other PDA's in the surrounding and remote servers. Users can report about their environment using a personalized iconic language. Each user is supervised by a personal agent. In case of emergency users are routed outside a dangerous area using a personalised dynamic routing system, called PIRA "Personal Intelligent Routing Assistant". The system and results of testing will be presented in this paper.
Abstract: In the near future, intelligent agents on mobile devices will push to as well as request location-dependent information from users at convenient and
inconvenient times. In this paper, we consider the negative effects of mobile agent interruption and present strategies to reduce these effects drawn from
social psychology and task-interruption literature. We propose the implementation of social behaviours to minimize the negative effects of (task) interruptions caused by mobileagents and report the results of two studies that evaluate two social behaviours agents can adopt. The results from these studies
indicate that a mobile agent adopting social system behaviour can lead to a less disruptive user experience.
