1. A method, comprising:
receiving, by a first electronic device, a projection interface of a first application running on a second electronic device;
receiving, by the first electronic device, a first input of a stylus pen of a user in the projection interface, wherein the first input comprises a second input and a third input;
drawing, by the first electronic device and based on the third input, a second layer comprising a second handwriting trajectory; and
displaying, by the first electronic device, an updated projection interface,
wherein the updated projection interface comprises a first layer and the second layer, and
wherein the first layer comprises a first image that comprises a first handwriting trajectory and that is generated by the second electronic device based on the second input,
wherein a length of a first input time period of the third input is based on a first latency or a second latency,
wherein the first latency is from the first electronic device obtaining a second image from the second electronic device, and
wherein the second latency is from the first electronic device generating the second handwriting trajectory.
