SurfaceStreams: A Content-Agnostic Streaming Toolkit for Interactive Surfaces
ACM UIST 2018 Adjunct Proceedings (bib)

We present SurfaceStreams?, an open-source toolkit for recording and sharing visual content among multiple heterogeneous display-camera systems. SurfaceStreams? clients support on-the-fly background removal and rectification on a range of different capture devices (Kinect & RealSense? depth cameras, SUR40 sensor, plain webcam). After preprocessing, the raw data is compressed and sent to the SurfaceStreams? server, which can dynamically receive streams from multiple clients, overlay them using the removed background as mask, and deliver the merged result back to the clients for display. We discuss an exemplary usage scenario (3-way shared interactive tabletop surface) and present results from a preliminary performance evaluation.
