Abstract: Techniques for area of interest subscription are described herein. In some examples, a requestor, such as a client or other component, may be focused on a particular area of interest within a virtual space. A requestor may, for example, provide information indicating its area of interest within the virtual space. This information may then be used to determine one or more sub-spaces that are at least partially included within the area of interest. The requestor may then be subscribed to each sub-space that is at least partially included within the area of interest. When subscribed to a sub-space, object registration information indicating one or more objects that are registered to the sub-space may be received from one or more sub-space components that are associated with the sub-space.
