ReactSpace: Spatial-Aware User Interactions for Collocated Social Live Streaming Experiences

摘要

Live streaming is becoming an increasingly popular medium for social interaction on mobile devices. However, in most cases live streaming experience is still confined to a single-viewpoint, monoscopic video stream, which, in active scenarios such as outdoor or public event broadcasting, makes it hard or even impossible for viewers to understand a remote situation. This study investigates how live stream viewing can be improved through introduction of user spatial data into video stream composition and interaction, by developing a system that allows watching multiple spatially oriented video streams in virtual spaces simultaneously, and interaction with them through voice and spatially distributed reaction buttons. According to results of a preliminary study, users show a statistically significant interest in using spatial live stream viewing and interaction features. Believing that this solution presents a novel approach to social live video streaming, the rest of the article discusses the results and possible extensions of developed system.
