Human motion capture algorithm for creating digital shadows of the movement process

Journal of Physics Conference Series (2022)

Artem Obukhov Andrey Volkov Nadezhda A Vekhteva Daniil Teselkin Alexey E Arkhipov

Abstract The improvement of virtual reality systems declares new requirements for the user immersion quality. To improve the immersiveness of the interaction process with virtual space, it is necessary to provide a realistic representation of a person in it, as well as the processes of his movement and interaction with virtual objects. In this work, the issue of using motion capture technologies to create a realistic avatar (digital shadow) and visualization of the movement process is considered. An algorithm for capturing human movements based on synchronization of various hardware solutions has been developed to create a digital shadow of the human movement process. The algorithm can be used to match the user with his virtual copy in virtual reality systems. The scientific novelty of the method lies in taking into account the position, direction and speed of a person’s movement, synchronization of the motion capture hardware tools used to create digital shadows of the person’s movement process.

Optimization of human tracking systems in virtual reality based on a neural network approach

Scientific and technical journal of information technologies mechanics and optics (2023)

Artem Obukhov Daniil Teselkin

The problem of determining the optimal number and location of tracking points on the human body to ensure the necessary accuracy of reconstruction of kinematic parameters of human movements in virtual space is considered. Optimization of the human tracking system in virtual reality has been performed to reduce the amount of transmitted information, computational load and cost of motion capture systems by reducing the number of physical sensors. The task of optimizing the number and location of tracking points on the human body necessary for the reconstruction of a virtual body model from a limited set of input points using numerical approximation of the regression function is set. An algorithm has been developed for collecting a large amount of data from a human body model in a virtual scene and from a motion capture suit in the real world. The smallest number of human body tracking points and their location were obtained using the proposed algorithm. Various neural network topologies have been trained and tested to approximate the regression relationship between a vector of tracking points limited in size (from 3 to 13) and a vector of 18 virtual points used for the complete reconstruction of the human body model. The necessary accuracy of reconstruction of kinematic parameters of human movements is provided at 5 and 7 input points. The proposed approach made it possible to use 5 or 7 physical sensors to build a model of the human body and restore the kinetic parameters of its movements in virtual reality. The approach can be applied to solving inverse kinematics problems in order to reduce the number of physical sensors placed on the surface of the object under study, to simplify the processing and transmission of information. By combining data from both the motion capture suit and the virtual avatar, the process of collecting information has been significantly accelerated, the volume of the training sample has been expanded and various patterns of user body movements have been modeled.

АВТОМАТИЗИРОВАННАЯ СИСТЕМА УПРАВЛЕНИЯ ИССЛЕДОВАТЕЛЬСКИЙ УНИВЕРСИТЕТ ПРОЕКТОВ

Electronic document management is used in designing, manufacturing and sales of industrial products. The need to develop modern automated information systems is caused by a huge amount of documents to be stored and processed. The paper discusses the issues of constructing such complex electronic document management systems in their interaction with the information systems of company product catalogs and other types of electronic documents. These systems are developed to solve a number of tasks, such as ensuring fast access to information, storage and protection of documents, document flow management, etc. We describe a mathematical model for electronic catalogs in the form of a graph. Based on traveling salesman problem the task of project optimization has been stated. The authors describe the effect of combined application of electronic product catalogs and document management systems within the company. DOI: http://dx.doi.org/10.12731/2227-930X-2014-1-4

Разработка программного обеспечения для анализа влияния технологий виртуальной реальности на процесс перемещения человека

Вестник ВГУ Серия Системный анализ и информационные технологии (2024)

Artem Obukhov Denis Dedov Andrey Volkov Надежда Андреевна Вехтева Alexandra Nazarova

Среди распространенных подходов к организации перемещения в виртуальной реальности можно выделить использование специализированных контроллеров, беговых дорожек и всенаправленных платформ. В рамках данного исследования рассматривается влияние виртуальной реальности на процесс перемещения человека на различных видах платформ. Для отслеживания специфики данного процесса используются два вида оборудования: датчики виртуальной реальности (трекеры), отслеживающие траекторию перемещения, датчик мышечной активности, закрепленный на ноге пользователя. Разработан и формализован алгоритм сбора, обработки и анализа информации о процессе движения с использованием выбранного оборудования. Проведены экспериментальные исследования по влиянию виртуальной реальности на процесс перемещения человека в двух средах: в обычных условиях и на беговой дорожке. Разработанный алгоритм успешно апробирован в рамках экспериментальных исследований, что позволило оценить эффект влияния виртуальной реальности на траекторию движения и мышечную активность. Собранные данные (траектории и скорость трекеров, мышечная активность) обработаны статистическими методами (тест Шапиро — Уилка и U-тест Манна — Уитни), что позволило оценить нормальность распределения данных и осуществить попарное сравнение выборок, полученных при движении как в шлеме виртуальной реальности, так и без него. В результате не обнаружено статистически значимой разницы между траекториями движения ног. Выявлено различие в мышечной активности человека и скорости перемещения в процессе использования виртуальной реальности. Таким образом, гипотеза частично подтверждается. В результате исследования было подтверждено, что существует определенная разница в характере перемещения человека при использовании технологий виртуальной реальности.
