StreamSpace: Pervasive Mixed Reality Telepresence for Remote Collaboration on Mobile Devices

We present a system that exploits mobile rotational tracking and photospherical imagery to allow users to share their environment with remotely connected peers “on the go.” We surveyed related interfaces and developed a unique groupware application that shares a mixed reality space with spatially-oriented live video feeds. Users can collaborate through realtime audio, video, and drawings in a virtual space. The developed system was tested in a preliminary user study, which confirmed an increase in spatial and situational awareness among viewers as well as reduction in cognitive workload. Believing that our system provides a novel style of collaboration in mixed reality environments, we discuss future applications and extensions of our prototype.

Mixed Reality Experience - How to Use a Virtual (TV) Studio for Demonstration of Virtual Reality Applications.

The article discusses the question of “How to convey the experience in a virtual environment to third parties?” and explains the different technical implementations which can be used for live streaming and recording of a mixed reality experience. The real-world applications of our approach include education, entertainment, e- sports, tutorials, and cinematic trailers, which can benefit from our research by finding a suitable solution for their needs. We explain and outline our Mixed Reality systems as well as discuss the experience of recorded demonstrations of different VR applications, including the need for calibrated camera lens parameters based on realtime encoder values.

BOLCOF: base optimization for middle layer completion of 3D-printed objects without failure

3D printing failures can occur without completion of printing process due to shaking, errors in printer settings, and shape of the support material and 3D model. In such case it could be difficult to restart printing process from the last printed layer in conventional 3D printers, as the printing parts to which the nozzles are supposed to be attached are lost. In order to restart printing from the middle layer, Wu et al.[Wu et al. 2017] proposed a method of printing while rotating the base of a 3D printer. However, such approach required time for two objects to bond after segmentation, with limited availability of methods for adhesion between parts. Wu et al.[Wu et al. 2016] have also proposed a method to print 3D models at any angle through 5-axis rotation of the base of a 3D printer, but the manufacturing cost of such approach was relatively high. Therefore, we propose a system that prints 3D models on existing object by utilizing an infrared depth camera. Our method makes it possible to attach a 3D-printed object into a free-formed object in the middle of printing by recognizing its shape with a depth camera.

Distributed Metaverse: Creating Decentralized Blockchain-based Model for Peer-to-peer Sharing of Virtual Spaces for Mixed Reality Applications

Mixed reality telepresence is becoming an increasingly popular form of interaction in social and collaborative applications. We are interested in how created virtual spaces can be archived, mapped, shared, and reused among different applications. Therefore, we propose a decentralized blockchain-based peer-to-peer model of distribution, with virtual spaces represented as blocks. We demonstrate the integration of our system in a collaborative mixed reality application and discuss the benefits and limitations of our approach.
