Abstract
This paper presents the design and architectural formalization of a mixed reality (MR) system for pilot training that supports selective, region-level visual scene substitution. The proposed approach enables context-aware replacement of semantically meaningful regions within the pilot’s egocentric view - such as cockpit displays and external windows - while preserving direct physical interaction with real cockpit controls and the pilot’s hands. The core contribution is a modular real-time architecture that integrates semantic perception, structured scene representation, and GPU-accelerated mask-based compositing into a unified dataflow pipeline. The system is designed with explicit latency-aware modelling to support analytical evaluation of performance under strict real-time constraints (targeting below 20-30 ms). A functional prototype was implemented and evaluated under different hardware configurations. Experimental results demonstrate that the GPU-accelerated version running on an NVIDIA RTX 3060 achieves an average end-to-end latency of 26.3 ms (approximately 38 fps) with improved temporal stability. These results confirm the practical feasibility of the proposed architecture under controlled conditions. Adopting a design-science perspective, this work combines analytical modelling, architectural design, and preliminary prototype validation. The study addresses the need for stronger technical grounding in XR-based aviation training research prior to large-scale human-subject evaluation. The presented approach provides a reproducible foundation for the development of hybrid training systems that combine the sensorimotor fidelity of physical cockpits with the instructional flexibility of real-time visual substitution.

Gamification of Learning Scratch in Elementary School

Authors: Serhii D. Prykhodchenko, Oksana Yu. Prykhodchenko, Olha S. Shevtsova, and Sergii Yu. Semenov

Published in: OASIcs, Volume 81, First International Computer Programming Education Conference (ICPEC 2020)

Abstract
The article deals with the problem of gamification for primary school students. The main idea of creating a software product was to create the correct programming sequences for solving simple programming problems in the Scratch programming environment. The technological preconditions for creating an application are described; a review of gamification basics has been carried out. In this article, we first illustrate the current art of state of gamification. Then we discuss requirements for teaching and studying Scratch for primary school students, and then we describe the development of a game application for teaching Scratch programming constructions. In the experimental section we compare the results of the experimental and control groups of primary school students, which showed differences in the levels of knowledge of primary school students after the experiment, where the results of the experimental group are higher than results of the control group
