The paper presents the development trends of the modern higher education system of the Republic of Uzbekistan, the concept of the use of virtual reality in the education system, the comparative characteristics of the classical higher education system with the education system using virtual reality, which leads to greater efficiency at low cost. The development of a virtual laboratory, made at the Tashkent University of Information Technologies, on the Unity platform using the example of Arduino Uno, is given.

Fully automated test-based grading is crucial to cope with large numbers of student homework code. AuDoscore extends JUnit and keeps the task of creating exercises and corresponding grading tests simple. Students have a set of public smoke tests available. Grading also uses additional secret tests that check the submission more intensely. AuDoscore ensures that submissions cannot call libraries if the lecturer explicitly forbids them. Grading is not susceptible to the problem of consecutive faults by partially replacing student code with cleanroom code provided by a lecturer. AuDoscore can be run as a stand-alone application or integrated into our Exercise Submission Tool (EST). This paper briefly describes how both tools interact, depicts AuDoscore from the point of view of the lecturer, and describes some key technical aspects of its implementation.

Pose tracking does not yet reliably work in large-scale interactive multi-user VR. Our novel head orientation estimation combines a single inertial sensor located at the user's head with inaccurate positional tracking. We exploit that users tend to walk in their viewing direction and classify head and body motion to estimate heading drift. This enables low-cost long-time stable head orientation. We evaluate our method and show that we sustain immersion.

No-Pose (NP) tracking systems rely on a single sensor located at the user's head to determine the position of the head. They estimate the head orientation with inertial sensors and analyze the body motion to compensate their drift. However with orientation drift, VR users implicitly lean their heads and bodies sidewards. Hence, to determine the sensor drift and to explicitly adjust the orientation of the VR display there is a need to understand and consider both the user's head and body orientations. This paper studies the effects of head orientation drift around the yaw axis on the user's absolute head and body orientations when walking naturally in the VR. We study how much drift accumulates over time, how a user experiences and tolerates it, and how a user applies strategies to compensate for larger drifts.

We analyzed the methods and means of quality monitoring of the functioning of natural protective forest stands along the railroad tracks. On the basis of experimental studies, we identified the factors of horizontal and vertical structure of protective consortive ecotones (PCE), influencing the effectiveness of protection of the railroad tracks and the natural environment as a whole. We propose structures of basic modules for the quality monitoring system over the functioning of the PCE along the railroad tracks on the basis of the generalized structure of information systems (IS), smart measuring instruments of which can be automatically synthesized by MEMS technology. There was developed a mathematical model of tree diameter growth taking into account the effect of photosynthesis, which will allow predicting the index of PCE condition.

This paper presents a novel approach for the augmentation of social behaviors in virtual reality (VR). We designed three visual transformations for behavioral phenomena crucial to everyday social interactions: eye contact, joint attention, and grouping. To evaluate the approach, we let users interact socially in a virtual museum using a large-scale multi-user tracking environment. Using a between-subject design (N = 125) we formed groups of five participants. Participants were represented as simplified avatars and experienced the virtual museum simultaneously, either with or without the augmentations. Our results indicate that our approach can significantly increase social presence in multi-user environments and that the augmented experience appears more thought-provoking. Furthermore, the augmentations seem also to affect the actual behavior of participants with regard to more eye contact and more focus on avatars/objects in the scene. We interpret these findings as first indicators for the potential of social augmentations to impact social perception and behavior in VR.

The principle of network construction and the principle of request signals service of Secondary surveillance radar systems predetermined the work of the respondents of the considered systems in conditions of intra-system and intentional correlated and uncorrelated interferences. The article estimates the impact of masking fluctuation interferences on the quality of the request signals detection. It is shown that the choice of time-interval codes as the request signals predetermined the low noise immunity of the considered systems when a channel is exposed by the fluctuation interference.

With free movement and multi-user capabilities, there is demand to open up Virtual Reality (VR) for large spaces. However, the cost of accurate camera-based tracking grows with the size of the space and the number of users. No-pose (NP) tracking is cheaper, but so far it cannot accurately and stably estimate the yaw orientation of the user's head in the long-run. Our novel yaw orientation estimation combines a single inertial sensor located at the human's head with inaccurate positional tracking. We exploit that humans tend to walk in their viewing direction and that they also tolerate some orientation drift. We classify head and body motion and estimate heading drift to enable low-cost long-time stable head orientation in NP tracking on 100 m×100 m. Our evaluation shows that we estimate heading reasonably well.
