Abstract: A video conferencing system includes a multi-user interaction slate for the execution of applications having a state that is responsive to inputs from multiple attendees of a video conference. The video conferencing system includes a graphical user interface having video slates provided for video streams and multi-user interaction slates for the execution of code that is responsive to inputs provided at multiple client devices. The video conferencing system can determine a current state of a multi-user interaction slate in response to inputs provided by users of the client devices in association with the multi-user interaction slate. The video conferencing system can provide data for rendering the graphical user interface, including video data associated with the video slates and data indicative of the current state of the multi-user interaction slate.
