and receiving a second signal from the stylus when a distance between a tip of the stylus and a screen of the electronic device is less than a preset distance, wherein the first signal and the second signal comprise square wave signals, or the first signal and the second signal comprise baseband signals. ### Claim 9 (depends on 1) The method of claim 1, wherein not displaying the cursor at the second position of the display interface comprises not displaying the cursor at the second position of the display interface after a preset length of time from receiving the third control information, wherein the cursor is still displayed within the preset length of time from receiving the third control information. ### Claim 10 (depends on 9) The method of claim 9, further comprising: receiving a seventh control information; and performing a tap operation on content corresponding a position of the cursor within the preset length of time from receiving the third control information. ### Claim 11 A system for presentation control, comprising: a stylus; and an electronic device coupled to the stylus via Bluetooth, wherein the electronic device is configured to: display a first interface that comprises a first control and a first prompt information, wherein the first prompt information comprises introduction information of presentation operation, and the presentation operation comprises at least one of a displaying cursor operation and a moving cursor operation; wherein the stylus is configured to send a first control information in response to the stylus is being long pressed and, wherein after receiving the first control information, the electronic device is further configured to display a cursor at a first position of a display interface, wherein the stylus is further configured to send a second control information in response to the stylus being moved when the stylus is being long pressed, wherein after receiving the second control information, the electronic device is further configured to display the cursor being moved from the first position to a second position on the display interface, wherein the stylus is further configured to send a third control information after the stylus has stopped being long pressed, wherein after receiving the third control information, the electronic device is further configured to not display the cursor at the second position of the display interface, wherein the stylus is further configured to send a fourth control information in response to the stylus being long pressed, and wherein after receiving the fourth control information, the electronic device is further configured to display the cursor at the first-second position of the display interface. ### Claim 12 An electronic device, comprising: one or more processors; and a memory coupled to the one or more processors and configured to store instructions that, when executed by the one or more processors, cause the electronic device to be configured to: display a first interface that comprises a first prompt information, wherein the first prompt information comprises introduction information of presentation operation, and the presentation operation comprises at least one of a displaying cursor operation and a moving cursor operation; receive a first control information from a stylus, and display a cursor at a first position of a display interface, wherein the first control information is in response to the stylus being long pressed; receive a second control information from the stylus, and display, on the display interface, the cursor being moved from the first position to a second position, wherein the second control information is in response to the stylus being long pressed and moved; receive a third control information from the stylus, and not display the cursor at the second position of the display interface, wherein the third control information is in response to the stylus stopping being long pressed;
