There currently are several views on human computer interaction in measuring interactive qualities: ( I ) the interaction-oriented view, (2) the user-oriented view, (3) the product-oricnted view and (4) the formal view. Two different possibilities of measurement within the product-oriented view are introduced in this paper. Different types of user interfaces can be described and differentiated ...

Knowledge-intensive work in business practice is usually supported by rather static media where expressiveness and ease of content consumption are paid for by a high effort for content creation. In the area of highly interactive collaboration, however, physical media like whiteboards dominate because of the speed and ease of content creation. Regrettably, physical media come with a number of sh...

ion exercised in “D-Tower” (e.g., calculated statistics representing mood with color), our interface depicts the social nature of the place with the directness of the voice, and intends to capture the subtleties of intonation, stress and mood embedded in the voices accompanying their message. In our design, we inspire to the kind of social responsibility rooted in Wodizcko’s work. Similar to th...

This paper is concerned with the state estimator design problem for perturbed linear continuous-time systems with H1 norm and variance constraints. The perturbation is assumed to be time-invariant and norm-bounded and enters into both the state and measurement matrices. The problem we address is to design a linear state estimator such that, for all admissible measurable perturbations, the varia...

Virtual Reality is used successfully to treat people for regular phobias. A new challenge is to develop Virtual Reality Exposure Training for social skills. Virtual actors in such systems have to show appropriate social behavior including emotions, gaze, and keeping distance. The behavior must be realistic and real-time. Current approaches consist of four steps: 1) trainee social signal detecti...

Formal Concept Analysis has become a real approach in the trend Information-Knowledge-Wisdom. It turns around the mining of a data set to built a concept lattice which provides an strong structure of the knowledge. Implications play the role of an alternative specification of this concept lattice and may be managed by means of inference rules. This syntactic treatment is guided by several prope...

Intrinsic motivation is what causes us to do something “for its own sake,” in contrast to doing something for an external reward. There is great interest in building intrinsic motivation into artificial systems by defining intrinsic reward signals within the reinforcement learning framework. Yet, what intrinsic reward signals are, and how it may differ from extrinsic reward signals, remains a m...

This paper introduces some advanced genetic algorithms for a complex hybrid flexible flow line problem with a makespan objective that was recently formulated. General precedence constraints among jobs are taken into account, as are machine release dates, time lags and sequence dependent set-up times; both anticipatory and non-anticipatory. This combination of constraints captures many real worl...

The immediacy and directness of our subjective visual experience belies the complexity of the neural mechanisms involved, which remain incompletely understood. This review focuses on how the subjective contents of human visual awareness are encoded in neural activity. Empirical evidence to date suggests that no single brain area is both necessary and sufficient for consciousness. Instead, neces...

OBJECTIVE The objective of this study was to assess the links between temperament and sleep in a group of preschoolers with ADHD. METHOD Twenty-five ADHD ( M = 5.37 years, SD = 1.09) and 22 typically developing (TD; M = 5.10, SD = 1.18) preschoolers participated in the study. Sleep was assessed with the Sleep Disturbance Scale and wrist actigraphy. The Preschool Temperament and Character Inve...
