In the execution of bridge or overpass decks several construction processes are applied. A geometric model 4D (3D + time) in a Virtual Reality (VR) environment which simulates the construction of a bridge deck composed of precast beams was implemented. The model allows viewing and interaction with the various steps and the main elements involved in the construction process. In order to develop the virtual model, the components of the construction, the steps inherent in the process and its follow-up and the type and mode of operation of the required equipment were initially examined, in detail. Based on this study, the 3D geometric modelling of the different elements that make up the site was created and a schedule that would simulate an interactive mode of construction activity was established. As the model is interactive, it allows the user to have access to different stages of the construction process, thus allowing different views in time and in space throughout the development of construction work, thereby supporting understanding of this constructive method. Since the model is didactic in character it can be used to support the training of students and professionals in the field of Bridge Construction. The VR application is currently used to support Bridge classes.

Bar-codes and QR-codes (Quick Response) are often used in healthcare. In this paper an application of QR-codes to exchange of laboratory results is presented. The secure data exchange is proposed between a laboratory and a patient and between a patient and Electronic Health Records. Advanced Encryption Standard was used to provide security of data encapsulated within a QR-code. The experimental setup, named labSeq is described. Additionally, a mobile application which enables decoding and storage of the enciphered information is presented. This work is also a preliminary research in supplying electronic glasses device, eGlasses, a functionality to process data from graphical patterns. In this paper a mobile phone is used as a simulator of electronic glasses. The exchange of data between the mobile application and Electronic Health Records is based on Health Level 7 standards or using JavaScript Object Notation. This enables fast integration of data between a patient's device and the information system used by a healthcare professional.

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 are highly noisy and contain many outliers, 2) EEG signals are high dimensional. Therefore the contribution of this paper is a novel methodology for recognizing thought patterns based on Self Organizing Maps (SOM). The presented thought recognition methodology is a three step process which utilizes SOM for unsupervised clustering of pre-processed EEG data and feed-forward Artificial Neural Networks (ANN) for classification. The presented method was tested on 5 different users for identifying two thought patterns; “move forward” and “rest”. EEG Data acquisition was carried out using the Emotiv EPOC headset which is a low cost, commercial-off-the-shelf, noninvasive EEG signal measurement device. The presented method was compared with classification of EEG data using ANN alone. The experimental results for the 5 users chosen showed an improvement of 8% over ANN based classification.

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 via in two displays simultaneously.

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 not only the shape of road network but also the directed road network, which could not be estimated by the use of only aerial/satellite images. The proposed method to solve this problem includes three stages. First, a raw network of path for motion is detected using the road map images. Second, the path network is converted to the Global coordinates, which provides a convenience for online auto-navigation task. Third, the shortest path for motion is estimated based on the A* algorithm. The experimental results demonstrate robustness and effectiveness of the method for path networks estimation under the large scene of outdoor environments.

The paper presents a method of using the UML state machine diagrams for specification of programs of logic controllers. The proposed method allows transformation from UML state machine diagram, using temporal Hierarchical Concurrent Finite State Machine (HCFSM) model, into Verilog hardware specification. The generated behavioral description in Hardware Description Language can afterwards be simulated, synthesized and implemented into e.g. FPGA device. A practical example illustrating the successive stages of the proposed method was also presented.

In this paper we present a new human-computer interface for the quantitative measurement of blowing activities. The interface can measure the air flow and air pressure during the blowing activity. The measured values are stored and used to control the state of the graphical objects in the graphical user interface. In speech therapy children will find easier to play attractive therapeutic games than to perform repetitive and tedious, traditional blowing actions. Therefore, we also propose a set of games that can be used together with the blowing device. The paper focuses on the design of the interface, preliminary experiments and results. Additionally, fours blowing games are described.

In general case, reconfigurable logic controllers (RLC) are included into reactive digital embedded systems, carrying out control for several processes proceeding concurrently. The paper presents a practical application of a formal, rule-based specification language in Gentzen sequent logic, which is used as an intermediate textual description of a control interpreted Petri net. On the other hand exactly the same description serves also as logic design expressions, related with different versions of functionally equivalent concurrent state machine models, considered on Register Transfer Level. The symbolic rule-based specification of Petri net-based embedded Logic Controllers (LCs) can be step-by step formally transformed into the final specification of concurrent state machine model, closely related with VHDL description, suitable for a direct mapping in reconfigurable logic devices. In this paper it is proposed novel compact form of logic descriptions, directly based on event-oriented specification, where it is assumed that macrocells can be implicitly formed by synthesis tool as containing virtual T flip-flops.

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, and then used for direct posture estimation of unoccluded phalanges. Inverse kinematics provide the missing information in case of occlusion. Our approach can be related to an inverse kinematics approach based on fingertip detection, with additional robustness to fingertip occlusion provided by the medial axis of each visible phalanx.

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 evaluated. Experimental results are presented.
