Abstract:
Live streams have been gaining importance in Human-Computer Interaction research and practice. A specific type of these broadcasts is the knowledge sharing live stream (KSLS). Embrapa (Brazilian Agricultural Research Corporation) uses KSLSs to disseminate its research results. In this paper we investigate its audience engaged with the material at different moments. We monitored nine of Embrapa’s broadcasts, applied an online survey to the viewers, analyzed access statistics and conducted semi-structured interviews. Our goal was to contrast our findings in KSLS’s audience engagement in live and on-demand periods with the literature on this topic, answering the following research questions: How does the engagement of KSLSs viewers differ in real-time and on-demand? Which features could increase this engagement in these two different periods? In this way, according to our results, the takeaways of this work are i) the live period attracted the public more and promoted more interactions,
ii) the live audience wishes that the video be made available on-demand, iii) new features, such as support for content documentation, multiple-choice questions, and temporal segmentation could increase the engagement in real-time and on-demand moments, and iv) our public did not have a large preference for interacting via audio in the chat.
