Identifying at least one object among the virtual objects based on the spatial information while the at least one application is running;
A mobile device that selects at least a part of the at least one object based on the remaining storage space of the wearable device. The method of claim 14,
The mobile device, wherein the at least one processor identifies the at least one object based on whether a distance between the wearable device and the virtual objects in the virtual space is less than a first distance. The method of claim 14,
The at least one processor is:
After transmitting the modeling data associated with the first object to the wearable device, identifying a second object distinct from the first object based on the spatial information;
determining a priority between the first object and the second object when the remaining storage space of the wearable device is insufficient;
In response to determining that the first object has a higher priority than the second object, determine not to transmit modeling data associated with the second object to the wearable device;
In response to determining that the first object has a lower priority than the second object, a first request to delete the modeling data associated with the second object and the modeling data associated with the first object by the wearable device. A mobile device that transmits a request signal. The method of claim 16
The first object is associated with a first application,
The second object is associated with a second application,
Wherein the at least one processor determines the priority between the first object and the second object according to the priority between the first application and the second application. The method of claim 16
The first object and the second object are associated with a first application,
The at least one processor further uses the spatial information to determine a priority between the first object and the second object. The method of claim 14,
The at least one processor is:
After transmitting the modeling data associated with the first object to the wearable device, identifying a second object distinct from the first object based on the spatial information;
Transmitting a part of modeling data associated with the second object to the wearable device when the remaining storage space of the wearable device is insufficient. The method of claim 14,
The at least one processor is:
After transmitting the modeling data associated with the first object to the wearable device, identifying a second object distinct from the first object based on the spatial information;
When the remaining storage space of the wearable device is insufficient, transmitting a second request signal requesting to delete modeling data associated with the second object and a part of the modeling data associated with the first object, mobile device .
