描 い When drawing or taking notes with a smartphone or tablet equipped with a touch panel, it is easier to use a stylus to perform detailed operations than to directly touch the screen with a finger. However, it is difficult to perform a touch operation on the screen while holding the stylus.
に 対 し In response, Apple has devised a technology that allows touch operations on the stylus. When the technology was filed with the United States Patent and Trademark Office [USPTO],TOUCH-BASED INPUT FOR STYLUS[Published patent number "US 2020/0012358 A1"]. The filing date is July 6, 2018.

The touch sensor has a thin shape and can be embedded inside the stylus. Then, in order to be able to perform a touch operation on the stylus while holding the stylus naturally, the movement of the finger touching the sensor is distinguished as a touch operation or just touching the hand held.

By providing such a mechanism, tap operation and slide operation on the stylus become possible. Furthermore, the operation of sliding the finger to rotate the axis of the stylus can be recognized as a gesture.
