To increase police officer awareness of incident locations, the Dutch police developed and implemented a location-based notification system (LBNS). This mobile service notifies police officers proactively to warrants, agreements and police focal points in their current vicinity. To assess the accuracy, efficiency, effectiveness and user experience of this(More)
In the mobile computing environment, there is a need to adapt the information and service provision to the momentary attentive state of the user, operational requirements and usage context. This paper proposes to design personal attentive user interfaces (PAUI) for which the content and style of information presentation is based on models of relevant(More)
To minimize unwanted interruption and information overload during surveillance, mobile police officers need to be supported by a mobile, context-aware notification system. This system adapts message presentation to message priority and context of use. A prototype is designed and evaluated in a simulated surveillance task, requiring users to attend to videos(More)
This paper describes a user walkthrough that was conducted with an experimental multimodal dialogue system to access a multidimensional music database using a simulated mobile device (including a technically challenging four-PHANToM-setup). The main objectives of the user walkthrough were to assess user preferences for certain modalities (speech, graphical(More)
In mobile computing, a fundamental problem is maintaining awareness of the environment and of information presented as messages on a mobile device. In mobile police patrol, officers need to pay attention to their direct environment and stay informed of incidents elsewhere. To prevent unwanted interruption, a context-aware notification system adapts the(More)
<b>Motivation</b> -- Automated task allocation systems are prone to errors (e.g. incorrect advice) due to context events. Empirical assessment is needed of how the costs of incorrect task allocation advice relate to the benefits. <b>Research approach</b> -- Claims regarding benefits and costs are tested in a team surveillance task in a synthetic task(More)
The European MIAMM-project (Multidimensional Information Access using Multiple Modalities) develops new concepts and techniques for multimodal dialogs that allow for fast and natural mobile access to multimedia databases. In an experiment we investigated different modality combinations (haptic-tactile, non-speech audio and a redundant combination) for(More)
