  • Patent number: 10649552
    Abstract: An input method and electronic device using a pen input device are provided. In an embodiment, status information of the pen input device is received, and contact information of a contact point between the pen input device and the terminal is generated, based on the received status information. Expressive effects of a pen input, such as line thickness, density and texture, are varied based on the contact information. Such input method and electronic device using the pen input device can simply and conveniently vary expressive effects of a pen-based input. In other embodiments, contact information is determined from actual contact points and expressive effects are varied as a function of the contact information or pen status information derived from the actual contact information.
