The article is a preliminary research that examines the methodology of the experiment devoted to the study of the speaker’s behavior in virtual reality (VR) and its results. The purpose of the experiment is to study the specific features of verbal and non-verbal implementation of the role and spatial deixis in VR. Based on the received reactions, the speaker’s coordinate system will be determined and models of the speaker’s communicative behavior in VR will be constructed. The article describes in detail the design of the experiment, which includes: stimulus material on the basis of which the VR scene is created; types of scenes used to determine the type of the speaker’s orientation; description of the tools by means of which VR is created; requirements for the selection of participants in the experiment; methods of recording material and the principles of its decoding. Special attention was paid to correlating the ‘external’ (gesture) and ‘internal’ (verbal) behavior of the speakers, to the principles of gesture fixation and their correlation with the subject’s verbal reactions to the presented scene. Based on the data obtained from the subjects, there was developed a classifier where the categories ‘Structure of the situation’, ‘Type of communication’ and ‘Means of communication’ and their subclasses are used. The data are entered into the Semograph information system and are visually presented in the form of a customizable interactive graph by using the SciVi software. At present, the reactions of two informants (a man and a woman) from the general sample have been processed. Based on the analysis of their reactions, preliminary results were obtained, which made it possible to demonstrate approaches to work with the classifier and to trace the representation of verbal and non-verbal means in the reactions of the subjects. Moreover, preliminary results help to determine the type of orientation and communicative behavior of the speaker depending on their personality and the type of scene. Preliminary analysis allows us to refine the principles of material processing, its annotation and entry into the Semograph system as well as working with the classifier.

Abstract In this paper we present a selection of preliminary results of our research project “Intonation and Meaning”, in which we compare recurrent intonation contours in German and Italian regional varieties. We apply the method of German Interactional Prosody Research (Interaktionale Prosodieforschung), which in turn is based on Conversation Analysis, to a sample of selfcollected empirical data. Our aim is to show the value of intonation as a resource to contextualize speech activities and to point out form-function relationships between intonation patterns and speech act types. In this respect, we observe the usage of intonation contours with rising accent (L*H) and with falling accent (H*L) in the utterance of question activities, and provide evidence for the fact that the latter represent a distinctive type of questions with epistemic presupposition, whereas L*H correlates rather with default, modally unmarked questions.

The innovative use of QuickTime Virtual Reality (QTVR) and panoramic image–creation utilities for recording field observations and measurements during routine bridge inspections is reported. A virtual reality approach provides the ability to document a bridge’s physical condition by using different media types at a significantly higher level of detail than is possible in a written bridge inspection report. Digitally recorded data can be stored on compact disc for easy access before, during, or after an inspection. The development of a QTVR bridge record consists of four major steps: selection of the camera stations, acquisition of the digital images, creation of cylindrical or cubic panoramas, and rendering of the QTVR file. Specific details related to these steps are provided, as applied to various bridge inspection projects. The potential impact of QTVR on bridge management—in which routine inspection data are a factor in making decisions regarding the future maintenance, rehabilitation, or replacement of a bridge—is discussed.

Professional truck drivers frequently face the challenging task of manually backwards manoeuvring articulated vehicles towards the loading bay. Logistics companies experience costs due to damage caused by vehicles performing this manoeuvre. However, driver assistance aimed to support drivers in this special scenario has not yet been clearly established. Additionally, to optimally improve the driving experience and the performance of the assisted drivers, the driver assistance must be able to continuously adapt to the needs and preferences of each driver. This paper presents the VISTA-Sim, a platform that uses a virtual reality (VR) simulator to develop and evaluate personalized driver assistance. This paper provides a comprehensive account of the VISTA-Sim, describing its development and main functionalities. The paper reports the usage of VISTA-Sim through the scenario of parking a semi-trailer truck in a loading bay, demonstrating how to learn from driver behaviours. Promising preliminary results indicate that this platform provides means to automatically learn from a driver’s performance. The evolution of this platform can offer ideal conditions for the development of ADAS systems that can automatically and continuously learn from and adapt to an individual driver. Therefore, future ADAS systems can be better accepted and trusted by drivers. Finally, this paper discusses the future directions concerning the improvement of the platform.

AbstractA survey is given on the tasks to be performed in the process of improving a fundamental system. Completed tasks are the derivation of corrections to the values for general precession and the determination of the FK4 equinox and equator. The selection of new fundamental stars and the improvement of the systematic and individual accuracy of the FK4 is in progress. A description of the observational material and of new methods of analysis is given. Preliminary results are reported.
