V-SENSE PI Professor Smolic is co-PI of new funded project “SpheryStream”!

We are delighted to announce a new innovative consortium led by Dr. Laura Toni (UCL) as the Principal Investigator (PI), and V-SENSE PI Professor Smolic (TCD), as co-PI who have been successful in securing funding for SpheryStream!

SpheryStream aims to design virtual and augmented reality systems (VR at large) for real-world use cases such as healthcare, entertainment, e-education, and high-risk missions by developing a coding/streaming/rendering chain that places the interactive user at the very heart of the system.

SpheryStream aims to overcome the challenges in immersive technology by developing an efficient tool for navigation patterns analysis in the spherical domain and leverage on that to predict users’ behaviour and build the entire coding-delivery-rendering pipeline as a user- and geometry-centric system. This proposal focuses on develop novel VR delivery strategies, which will rely on the analysis and prediction of the navigation patterns of the omnidirectional content navigation, in a user, content- and application-dependent fashion. Predicting users’ behaviour will allow to delivery only the content that will be actually consumed by the users, minimising the transmission resources consumption while maximising the user’s Quality of Experience (QoE).

The key novelty will be to address the above challenges working directly on the spherical domain, rather than on the projected (thus deformed) bidimensional domain. The developed VR system will be tested via a real omnidirectional video streaming testbed that will be implemented within the scope of the project. The outcomes of the project will be three-folds: i) user- content- and application-dependent VR streaming platform, optimized from the source codec to the delivery platform; ii) users analysis tools able to assess users’ behaviour (when interactive with the content) in an objective fashion to identify common navigation patterns, and to predict future behaviours; iii) VR streaming testbed to test the proposed technology. 

Dr. Laura Toni is the Principal Investigator at LASP (Learning And Signal Processing) at the Electronic Engineering Department at University College London.
