Abstract

A method of using an active stylus and a sensor controller is provided including generally four steps. The active stylus, in response to a trigger indicative of a pen lowering operation, sends replaceable pen tip information indicating a type of a replaceable pen tip that forms a pen tip of the active stylus. The sensor controller receives the replaceable pen tip information and identifies the replaceable pen tip type of the active stylus. The active stylus repeatedly sends a data signal including a pen pressure value applied to the replaceable pen tip. The sensor controller derives a position of the active stylus based on the data signal using a position deriving method that corresponds to the replaceable pen tip information.
