US 2021/0004197 A1 · VIRTUAL WORKSPACE VIEWPORT FOLLOWING IN COLLABORATION SYSTEMS

Abstract

A collaboration system is provided and includes memory storing collaboration data including a spatial event map locating events in a virtual workspace and a local display including a screen space. The collaboration system further includes logic to identify a local client viewport in the virtual workspace, logic to render, in the screen space on the local display, graphical objects identified by events in the spatial event map that have locations within the local client viewport, logic to change a location and a dimension of the local client viewport in the virtual workspace in response to input signals, logic to render, in the screen space on the local display, graphical objects identified by events in the spatial event map that have locations within the changed local client viewport, and logic to generate a viewport change event in response to the change of the local client viewport in response to input signals.

A collaboration system comprising:

a data processor;
memory storing collaboration data including a spatial event map which locates events in a virtual workspace;
a local display including a screen space;
logic to identify a local client viewport in the virtual workspace;
logic to render, in the screen space on the local display, graphical objects identified by events in the spatial event map that have locations within the local client viewport;
logic to change a location and a dimension of the local client viewport in the virtual workspace in response to input signals;
logic to render, in the screen space on the local display, graphical objects identified by events in the spatial event map that have locations within the changed local client viewport;

A non-transitory computer-readable recording medium having computer instructions recorded thereon, the computer instructions, when executed on one or more processors, causing the one or more processors to perform operations including:

storing, in a memory, collaboration data including a spatial event map which locates events in a virtual workspace;
identifying a local client viewport in the virtual workspace;
rendering, in a screen space of a local display, graphical objects identified by events in the spatial event map that have locations within the local client viewport;
changing a location and a dimension of the local client viewport in the virtual workspace in response to input signals;
rendering, in the screen space on the local display, graphical objects identified by events in the spatial event map that have locations within the changed local client viewport;
and
generating a viewport change event in response to the change of the local client viewport in response to input signals.
