The specification provides example service processing methods and devices. One example method includes detecting a device type of an electronic device. An instruction processing rule corresponding to the device type is obtained. The instruction processing rule includes an instruction set conversion rule defining a process for converting display modification instructions generated by the electronic device into unified display modification instructions. A first display modification instruction initiated in response to a user interacting with the electronic device is obtained based on the instruction processing rule. The first display modification instruction is converted into a corresponding first unified display modification instruction according to the instruction processing rule. A portion of interaction data output to a display us updated by invoking a service processing mode corresponding to the first unified display modification instruction.
