receiving circuitry to receive graphics data for at least a portion of a virtual environment, the graphics data including a plurality of virtual objects;

a machine learning model trained to output data indicative of an object classification for one or more of the virtual objects in dependence upon the graphics data;

assignment circuitry to assign one or more of the virtual objects to one or more virtual object groups in dependence upon the object classification for one or more of the virtual objects, wherein the virtual objects assigned to a same virtual object group have a same object classification; and

control circuitry to share first interaction data associated with a first virtual object assigned to a virtual object group with a second virtual object assigned to the virtual object group to thereby permit use of the first interaction data for the second virtual object in response to a user interaction with the second virtual object in the virtual environment, wherein the first interaction data is associated specifically with the first virtual object, wherein second interaction data is associated with the second virtual object, and wherein:

the control circuitry is configured to share one of the first interaction data and the second interaction data with a third virtual object assigned to the virtual object group to permit use of one of the first interaction data and the second interaction data for the third virtual object in response to a user interaction with the third virtual object in the virtual environment; and

the control circuitry is configured to detect a number of respective interaction types associated with the first interaction data and the second interaction data, respectively, and to share interaction data having the greatest number of respective interaction types with the third virtual object.
