METHOD CARRIED OUT BY STYLUS, METHOD CARRIED OUT BY DUAL STYLUS AND DUAL CONTROLLER, AND DUAL STYLUS

摘要

A method is carried out by a stylus, wherein the stylus is a dual stylus configured to be capable of transmitting signals pursuant to both a first system and a second system and receiving at least a signal pursuant to the first system. The dual stylus has a detection function of detecting a writing pressure applied to a stylus (pen) tip. The method includes detecting contact between the stylus and a touch surface based on the writing pressure detected by the detection function, activating a signal reception operation pursuant to the first system for a predetermined time period, and, responsive to reception of a signal pursuant to the first system in the predetermined time period, setting an operation mode of the stylus to a first operation mode, in which signals are transmitted and received pursuant to the first system.
