PokeRepo Go++: One-man Live Reporting System with a Commentator Function

In this paper, with propose PokeRepo Go++, which is our one-man live reporting system (PokeRepo Go) with an added commentator function that enables outside experts to make comments. As a consequence of the spread of live broadcast streaming services, anybody is now able to broadcast his/her own interests, concerns and everyday occurrences. To support reports made by a single person in the form of a live broadcast, we have developed and actually operated PokeRepo Go. PokeRepo Go only had a function to transmit video to viewers in one direction, i.e. non-interactively. For this reason, because an interviewee or reporter had no reaction from the audience, there was uncertainty as to whether the broadcast content was being conveyed to the audience as per his/her intention. This exposed the importance of two-directional, i.e. interactive, communication. In PokeRepo Go++, we provide a commentator function by which commentators can seamlessly participate in live broadcast content and communicate naturally with an interviewee. Additionally, we considered the UI design to realize the compatibility of use of the commentator function with use of the pre-existing PokeRepo Go functions, such as filming operations (including acquirement of video/audio and control of lighting) and editing operations. At a demo session in a domestic conference we operated the prototype system of PokeRepo Go++ and evaluated the usefulness thereof.
