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 refill body information indicating a type of a refill body that forms a pen tip of the active stylus. The sensor controller receives the refill body information and identifies the refill body type of the active stylus. The active stylus repeatedly sends a data signal including a pen pressure value applied to the refill body. The sensor controller derives a position of the active stylus based on the data signal using a position deriving method that corresponds to the refill body information.
