Sony has decided to patent several mechanisms for feedback when interacting with the touch screen. Applications are filed in the Office of the United States Patent and Trademark Office. Total Japanese inventors have issued four patents , but common to all solutions is the use of friction.
To interact with the touch screen Sony suggests using a special stylus. Stylus respond to the smartphone or tablet, changing the force of pressure on the ball holder (and, consequently, the friction that occurs between these elements.) As a result of moving the pen on the screen will be easier or harder.
