The domain of Emotional Business Intelligence (EBI) aims to support business-relevant emotional and emotion-aware decisions in addition to rational decision making. EBI originates from three root domains: Emotional Business, Emotional Intelligence and Business Intelligence (BI). In this paper we emphasize emotional empowerment of the traditional BI function; outline its main characteristics as a business...
Fuzzy logic provides a natural and precise way for humans to define and interact with systems. Optimizing a fuzzy inference system, however, presents some special challenges for the developer because of the imprecision that is inherent to fuzzy sets. This paper expands upon an earlier development of a fuzzy framework, adding components for dynamic self-optimization. What makes this approach unique...
Due to the huge size of the market for interactive games, game controllers are very cheap. Because of this they are a popular choice as input devices for research in user interfaces. The Software Development Kit that comes with each controller also makes it appealing compared with the effort of creating an original input device. We present a natural user interface for 3D interaction that uses a game...
For reducing the risk of pressure sore caused by long period sitting on a wheelchair, we have been developed a depressurization motion assistance system for a wheelchair user. Our developed system consists of a sitting surface lifting device and a backrest tension coordination device. Our system assists to realize the suitable posture of the seated patient with these two devices. In our previous works,...
The paper offers the model of an operator's vocational aptitude by way of the multiconnected system of professionally important qualities. The decision on the level of vocational aptitude is made by the of decision-making support system on the basis of fuzzy logic using the Mamdani algorithm. This results in the integrated assessment of vocational aptitude and an individual portrait of the level of...
The paper presents an approach to automatic recognition of emotions in speech signals. The applied method bases on the composition of two discrete frequency transformations. The wavelet transform was calculated first and next the Fourier transform was applied. The Fourier-wavelet transform representation is used to find the differences between emotions in speech signals. A set of approximately 30...
With escalating fuel prices, limited fossil fuel reserves and increasing carbon emissions, significant efforts are being made to decrease fuel consumption in vehicles. While, drivetrain improvements play a major role in improving fuel economy, it has been identified that fuel efficient driving behavior is a viable method for increased fuel efficiency. Thus, if the optimal fuel efficient behavior can...
Brain Computer Interfaces (BCI) have gained significant interest over the last decade as viable means of human machine interaction. Although many methods exist to measure brain activity in theory, Electroencephalography (EEG) is the most used method due to the cost efficiency and ease of use. However, thought pattern based control using EEG signals is difficult due two main reasons; 1) EEG signals...
In this paper empirical models for horizontal saccadic eye movements are proposed. One of the modelling main concerns were the empirical bandwidth requirements for the electrooculogram signals. The models permit to establish a threshold for the minimum sampling frequency and allow the computation of the human latency (reaction time). The effect of different sampling rates on the models quality is...
We propose a method for tracking a hand in real-time, using depth information from a single Kinect sensor. The fingers are segmented using medial axes on an image generated by the depth discontinuities. The palm position and orientation is estimated from the position of the wrist as well as the distance to the closest contour points. The detected medial axes are projected in the palm plane for labelling,...
Robot remote teleoperation enables users to perform complex tasks in hostile or inaccessible environments, without physical presence. However, minimizing collisions with obstacles while maintaining accuracy and speed of task is important. While visual and auditory inputs to the user aid in accurate control, to achieve the required speed and accuracy, tactile and kinesthetic force-feedback information...
In automatic navigation of mobile systems, first, they require providing a path network for robot/vehicle motion. Therefore, path planning is an important task of autonomous vehicle systems. To deal with the problem, this paper presents a method for constructing the shortest path, which support for vehicle auto-navigation in outdoor environments. The method using online road map images to estimate...
An influence of head movements on the gaze estimation accuracy when using a head mounted eye tracking system is discussed in the paper. This issue has been examined for a multi-display environment. It was found that head movement (rotation) to some extent does not influence on the gaze estimation accuracy seriously. Acceptable results were obtained when using eye-tracker to communicate with a computer...
Dynamic development of high quality cameras and algorithms processing eye movement signals entails growing interests in using them in various areas of human-computer interaction. Determining subjects which user is looking at or controlling the operation of computer processes can serve as examples of these areas. However, making eye movement signal valuable requires some preparatory steps to be taken...
