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.}, language = {en} } @article{RyskeldievCohenHerder2018, author = {Ryskeldiev, Bektur and Cohen, Michael and Herder, Jens}, title = {StreamSpace: Pervasive Mixed Reality Telepresence for Remote Collaboration on Mobile Devices}, series = {Journal of Information Processing}, volume = {26}, journal = {Journal of Information Processing}, publisher = {J-STAGE}, doi = {10.2197/ipsjjip.26.177}, pages = {177 -- 185}, year = {2018}, abstract = {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.}, subject = {Ubiquitous Computing}, language = {en} }
