Document Type and Number:
WIPO Patent Application WO/2023/020022
Kind Code:
A1
Abstract:
A stylus connection method and an electronic device, which relate to the technical field of electronic devices, and may ensure that the electronic device is connected to a plurality of styluses and displays touch tracks of the plurality of styluses. A specific solution comprises: an electronic device may separately establish a connection with a first stylus and a second stylus; the electronic device may receive, at a first sampling time, an electromagnetic wave signal of a first frequency and an electromagnetic wave signal of a second frequency, and receive a first pressure-sensitive identifier from a first stylus and pressure-sensitive data of the first stylus, and a second pressure-sensitive identifier from a second stylus and pressure-sensitive data of the second stylus, wherein the second pressure-sensitive identifier is different from the first pressure-sensitive identifier; and then, the electronic device may, according to the electromagnetic wave signal of the first frequency, the electromagnetic wave signal of the second frequency, the first pressure-sensitive identifier, the pressure-sensitive data of the first stylus, the second pressure-sensitive identifier and the pressure-sensitive data of the second stylus, display a touch track of the first stylus and/or a touch track of the second stylus.
