Adapting an automation system to the workload level of a human operator can be beneficial in many situations, e.g. at industrial workplaces or in safety-critical situations like driving and flying an aircraft. However, this requires real-time assessment of workload. We present a model-based approach for online simulation and assessment of cognitive workload, based on analysing the activities of a...
This paper presents a method for estimating difficulty of game tasks found in educational games. The method uses techniques from the field of socio-cognitive ICT, a branch of cognitive infocommunications. Our aim was to create an adaptive gaming experience for users of educational games. Adjusting the difficulty of game tasks according to the mental state of users is required for this approach. For...
In the scope of this article is the presentation of the idea of Intelligent TALENT SPACE meaning the basis of architectural planning bearing an innovative technical attitude that suits to serve the future generations. „The intelligent house of the future" presented in this article is a good example for the innovative solutions of CogInfoCom (P. Baranyi and A. Csapo, 2012, P. Baranyi, A. Csapo,...
Tactile and haptic devices can be used to control and interact with a wide range of systems, including games, virtual environments and assistive technologies. Although many psychophysical studies have measured thresholds of human sensory capabilities for interpreting haptic and tactile feedback, relatively little is known about the precision with which we are able to guide the behavior of a system...
This paper describes our experiences in developing multidisciplinary Wow experiences to boost business for small and medium-sized enterprises (SMEs). Wow experiences — outstandingly positive user experiences — are an increasingly important design target in product and service development contexts because they can help reveal customer needs. The basic idea in our Wow approach is to bring together various...
There are different theories to estimate cognitive abilities. Gardner proposed a model, where intelligence is defined by multiple fields instead of using one specific number. However, the characterization and automated evaluation of these fields are still open issues. If we can make standalone measurements in separate intelligence fields, the numerical modeling of the competencies is possible. Observing...
This paper proposes an original methodology designed to single out the speaker's social signals expressing either honesty or anxiety induced by his awareness of being suspected of deceit. 24 participants were randomly assigned to one of the three following experimental conditions (namely A, B and C), manipulated during a face-to-face interview. In condition A, participants could win an undeserved...
This study investigated the effect of a chance task outcome on the offers made at the Ultimatum Game (UG). In addition, the putative mediation role of incidental (unrelated to UG) and integral (elicited by UG) emotions and beliefs was examined. The incidental emotions were induced by manipulating the task outcome in a positive or negative direction. As concerns integral emotions and beliefs, we took...
In this paper, we present an animation developed in the Wolfram Mathematica System for the visualization of the m-convex hull of sets containing finitely many points on the Cartesian plane.
Being a new player in a multiplayer game is not an easy experience. If the game requires coordinated team play for success, an inexperienced player can receive a high amount of abuse because of what others view as bad plays. While the companies try to alleviate this problem by focusing on the offenders, we present another approach that can also help in decreasing toxic behavior. In our paper we introduce...
The article shows the design and implementation of a gesture control system, which determines the gesture from the movement of the hands. The presented gesture controller system can be built relatively easy from cheap components, so it is ideal development goal in case of a students' project also in the field of project based learning. The movement detected with distance measurement sensors, and the...
In this paper we introduce CoBoard1 Flowers, an audio-visual public installation for Prague Spring International Music Festival. An interactive visualization with floral motifs is shown and is controlled by a face detection technology, enabled by a computer vision algorithm. The visualization is controlled by the estimated position, distance, gender, and age of the participants. The visualization...
This paper presents a framework for the monitoring of hospitalized people, including fall detection capabilities, using an environmentally mounted depth imaging sensor. The purpose is to characterize the fall event, depending on the location of the person when the fall event happens. In particular, we distinguish two basic starting point conditions: fall from standing position (e.g. due to blood pressure...
The identification of emotional hints from speech shows a large number of applications. Machine learning researchers have analyzed sets of acoustic parameters as potential cues for the identification of discrete emotional categories or, alternatively, of the dimensions of emotions. Experiments have been carried out over records including simulated or induced emotions, even if recently more research...
The variation of spontaneous speech is much larger when compared to the planned speech because of speech disruption and a lot of ambiguities in conversations. These events cannot be properly evaluated during search and decoding in speech recognition systems and various errors occur in the output hypotheses. One possible solution is to include filled pauses and disfluent events into the training data...
Since mobile terminals such as smartphones are basic information tools for users, their communication performance is always significant. Modern loss-based Transmission Control Protocols (TCP) take aggressive congestion window (CWND) control strategies in order to gain better throughput, but such strategies may cause a large number of packets to be backlogged and eventually dropped at the entry point...
