The challenges of placing virtual objects in a real-world environment limit the potential of augmented reality (AR) technology. This situation identifies a gap in scientific knowledge that requires additional research. Therefore, the main task of this study was to develop a method for optimal placement of virtual objects, in which the objective function of comfort was minimized. This approach is aimed at improving AR systems and developing the corresponding theory.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. The conducted research was based on the analysis of the placement of virtual objects in AR/VR applications with particular emphasis on optimization. The concept of comfort of placement was proposed, taking into account the size of the object and the distance to the boundaries of free space in X, Y, Z coordinates.</p></sec><sec><title>Results</title><p>Results. As part of the study, formulas were obtained for the optimal placement of objects with an arbitrary comfort function. The basic criterion was to minimize the difference between comfort levels from different sides of the object. It was found that a successful placement of objects required taking into account their size and comfort zones, as well as solving a system of n linear equations.</p><p>Discussion and Conclusion. The results obtained make an important contribution to the study of the problem of placing virtual objects in AR/VR/MR. They open up new opportunities for improving user interaction and conducting further research in the field of spatial computing. Possible directions for further development are dynamic adjustments and integration of the results into various XR scenarios.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Введение</title><p>Введение. Проблемы, связанные с размещением виртуальных объектов в реальной среде, существенно ограничивают возможности технологии дополненной реальности (AR). Такая ситуация выявляет пробел в научных знаниях, требующий дополнительного исследования. Поэтому основной задачей данного исследования явилась разработка метода оптимального размещения виртуальных объектов, при котором происходит минимизация целевой функции комфортности. Такой подход направлен на усовершенствование систем AR и развитие соответствующей теории.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведенное исследование основывается на анализе размещения виртуальных объектов в AR/VR приложениях с особым акцентом на оптимизацию. Было предложено понятие комфортности размещения, учитывающее размеры объекта и расстояния до границ свободного пространства по координатам X, Y, Z.</p></sec><sec><title>Результаты исследования</title><p>Результаты исследования. В рамках исследования были получены формулы для оптимального размещения объектов с произвольной функцией комфортности. Основным критерием является минимизация разницы между уровнями комфортности с разных сторон объекта. Было выявлено, что успешное размещение объектов требует учета их размеров и зон комфортности, а также решения системы из n линейных уравнений.</p></sec><sec><title>Обсуждение и заключение</title><p>Обсуждение и заключение. Полученные результаты представляют собой важный вклад в исследование проблемы размещения виртуальных объектов в AR/VR/MR. Они открывают новые возможности для улучшения взаимодействия с пользователями и проведения дальнейших исследований в области пространственных вычислений. Возможными направлениями для дальнейшего развития являются динамические корректировки и интеграция полученных результатов в различные XR-сценарии.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дополненная реальность</kwd><kwd>виртуальные объекты</kwd><kwd>физическое пространство</kwd><kwd>рациональное размещение</kwd><kwd>математическая модель</kwd><kwd>уравнения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>augmented reality</kwd><kwd>virtual objects</kwd><kwd>physical space</kwd><kwd>optimal placement</kwd><kwd>mathematical model</kwd><kwd>equations</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">данное исследование осуществлено благодаря финансовой поддержке РФФИ в рамках научного проекта № 21–510–07004</funding-statement><funding-statement xml:lang="en">this research was carried out thanks to the financial support of the RFBR in the framework of scientific project no. 21–510–07004.
