In this paper a new approach to task analysis, Task Pattern Analysis, is presented within the context of Human-Robot Interaction (HRI). Task Pattern Analysis is based on the observation that in many work tasks there are recurring patterns of activity, which only differ in the concepts that are affected. Furthermore, the tasks appear in different ways depending on the situational context. By app...

Faulty decision making due to inaccurate or incomplete awareness of the situation tends to be the prevailing cause of fatal general aviation accidents. Of these accidents, loss of weather situational awareness accounts for the largest number of fatalities. We describe a method for improving weather situational awareness through the support of a contextaware, domain and task knowledgeable, perso...

Relevance, as shown by various cognitive and experimental studies, depends on a number of situational factors other than topicality. Formal IR models, on the other hand, only consider relevance from a topicality point of view. There is an urgent need of appropriate models which are able to consider relevance in a broader context. This paper is an attempt to find a theoretical tool suitable to t...

As the interest in the Web of Things increases, specially for the general population, the barriers to entry for the use of these technologies should decrease. Current applications can be developed to adapt their behaviour to predefined conditions and users preferences, facilitating their use. In the future, Web of Things software should be able to automatically adjust its behaviour to non-prede...

Previous research in cross-situational statistical learning has established that people can track statistical information across streams in order to map nonce words to their referent objects (Yu and Smith, 2007). Under some circumstances, learners are able to acquire multiple mappings for a single object (e.g., Yurovsky and Yu, 2008). Here we explore whether having a contextual cue associated w...

The use of prior situational/contextual knowledge about a given task can significantly improve Automatic Speech Recognition (ASR) performance. This is typically done through adaptation of acoustic or language models if data is available, or using knowledge-based rescoring. The main adaptation techniques, however, are either domain-specific, which makes them inadequate for other tasks, or static...

The notion of context in context-aware applications is not merely an issue of external situational circumstances or device/channel properties, but it could also refer to a wide array of user characteristics that have an effect throughout users’ interactions with a system. Human factors such as cognitive traits and current state, from a psychological point of view, are undoubtedly significant

Context An optimal software development process is regarded as being dependent on the situational characteristics of individual software development settings. Such characteristics include the nature of the application(s) under development, team size, requirements volatility and personnel experience. However, no comprehensive reference framework of the situational factors affecting the software ...

We posit that the modern airplane is a social microcosm of class-based society, and that the increasing incidence of "air rage" can be understood through the lens of inequality. Research on inequality typically examines the effects of relatively fixed, macrostructural forms of inequality, such as socioeconomic status; we examine how temporary exposure to both physical and situational inequality...
