AnArU, a virtual reality framework for physical human interactions

Virtual Reality has become, once again, a popular and interesting topic, both as a research and commercial field. This trend has its origin in the use of mobile devices as computational core and displays for Virtual Reality. Android is one of the most used platform in this context and Unity3d is a suitable graphic engine for such platform. In order to improve the immersive experience, some electronic devices, Arduino especially, are used to gather information, such as the movement of the user's arms or legs. Although these three elements are often used in Virtual Reality, few studies use all of them in combination. Those who do, do not develop a reusable framework for their implementations. In this work we present AnArU, a framework for physical human interaction in Virtual Reality. The goal of AnArU is to allow an easy, efficient and extensible communication between electronic devices and the Virtual Reality system.XIII Workshop Computación Gráfica, Imágenes y Visualización (WCGIV)Red de Universidades con Carreras en Informática (RedUNCI

Exploratory Experimentation of Three Techniques for Rotating a 3D Scene by Primary School Students

International audienceMulti-touch mobile devices are now commonly used in any area, including education. In this context we focus on applications for 3D geometry learning in primary schools. Manipulating a 3D scene based on a 2D input touch space is one key challenge of such applications for pupils. In this paper we present the results of an exploratory experimentation with pupils. We compare three different interaction techniques for rotating a 3D scene based on different interaction metaphors by using: multi-touch input, movements of the tablet captured with a gyroscope sensor and movements of the head captured by a camera-based head tracking. We ran the exploratory experiment with 28 pupils in a primary school to compare these three techniques by considering the performance and the subjective preferences. Results indicate worst performance for head-tracking and similar performance for multi-touch input and gyroscope-based movement. Qualitative results indicate participant preference for multi-touch interaction

Sistem pelacakan posisi pengguna menggunakan marker-based AR dalam menjelajahi galeri museum VR

This study examines the user position tracking system using marker-based AR on smartphones camera. The tracking system uses a homographic algorithm integrated into the Galeri Museum VR application. In the test, the user performed exploration interactions by 6 degrees of freedom in ten different positions in the museum gallery. The physical space used in this study was 4 x 4 m2 and a marker attached to the wall in front of the user. This system results in errors in XYZ field (0.102 m, 0.047 m, 0.044 m). If the camera's orientation is not directing to the marker and the user is moving, jitter appears because of the untracked marker. The use of marker-based AR successfully applied to track the position of users who perform natural locomotion interactions in the VR environment.Penelitian ini mengkaji sistem pelacakan posisi pengguna menggunakan marker-based AR pada smartphone berkamera. Sistem pelacakan menggunakan pengembangan algoritme homografi yang diintegrasikan ke aplikasi Galeri Museum VR. Pengujian dilakukan pada pengguna yang melakukan interaksi penjelajahan dengan 6 derajat kebebasan di sepuluh posisi yang berbeda di galeri museum. Ukuran ruangan fisik yang digunakan dalam pengujian adalah 4 x 4 meter persegi dan satu penanda ditempel pada dinding di depan pengguna. Sistem ini mampu menghasilkan galat bidang XYZ (0,102 m, 0,047 m, 0,044 m). Jika orientasi kamera tidak mengarah ke penanda dan pengguna bergerak, muncul jitter karena penanda tidak terlacak. Penggunaan marker-based AR dapat diterapkan untuk melacak posisi pengguna yang melakukan interaksi perpindahan posisi di lingkungan VR

Smartphone Based 3D Navigation Techniques in an Astronomical Observatory Context: Implementation and Evaluation in a Software Platform

International audience3D Virtual Environments (3DVE) come up as a good solution to transmit knowledge in a museum exhibit. In such contexts, providing easy to learn and to use interaction techniques which facilitate the handling inside a 3DVE is crucial to maximize the knowledge transfer. We took the opportunity to design and implement a software platform for explaining the behavior of the Telescope Bernard-Lyot to museum visitors on top of the Pic du Midi. Beyond the popularization of a complex scientific equipment, this platform constitutes an open software environment to easily plug different 3D interaction techniques. Recently, popular use of a smartphones as personal handled computer lets us envision the use of a mobile device as an interaction support with these 3DVE. Accordingly, we design and propose how to use the smartphone as a tangible object to navigate inside a 3DVE. In order to prove the interest in the use of smartphones, we compare our solution with available solutions: keyboard-mouse and 3D mouse. User experiments confirmed our hypothesis and particularly emphasizes that visitors find our solution more attractive and stimulating. Finally, we illustrate the benefits of our software framework by plugging alternative interaction techniques for supporting selection and manipulation task in 3D
