**3.3 The heliosphere visualisation engine**

Finally, the visualisation engine integrates rich-media of user-generated and broadcaster provided content to empower participants to point to content (hostbased, web or social media) to support or debunk arguments within a debate. Moreover, users can participate in validating if statements and content are valid and trustworthy.

To support live debates in hybrid (both online and offline) environments, HELIOSPHERE implements an immersive and interactive experience for an online debate calls for a variety of media elements such as 360° live video, Live video from remote individuals, Live generated closed captions, and automatic subtitles in different languages. This contributes to the immersive experience for Citizen participation and active contribution to a debate.

All interacting components need to be fast and synchronised so that they reach all viewers simultaneously. Since the diverse participants in the debate have differing roles and needs, these elements need to be i) object-based, ii) individually configurable, and iii) have low latency.

It is envisaged that the HELIOSPHERE provides the capability of covering debates on TV as an enhanced and interactive experience. This can be made possible via a central integration system offered by broadcasters. Moreover, data can be made available centrally and accessed directly by all interested journalists and newsrooms with just a few clicks. The use and republishing of the content are free of charge. The new content exchange platform is intended to enable citizens, and the content created is made available via diverse channels.

This can be provided as a recording or as a live debate. In this way, specific topics provided for free by the broadcasters can also be made available. For a debate to be planned, a schedule is to be developed, which allows the debate's organiser to define the services available for each debate, for example, Dashboard, 360° streaming, Link sharing for Twitter, Xing, LinkedIn, etc.
