US 10,649,553 B2 · Input device, electronic device for receiving signal from input device, and control method thereof

Abstract

An input device and method for control based on input device tilt is provided. The input device includes a conductive tip formed at one end of the input device, a resonant circuit unit configured to generate a response signal corresponding to a signal entering through the conductive tip and output the response signal through the conductive tip, and a connection part formed between the conductive tip and a body of the input device to enclose a periphery of the conductive tip so as to have a part of the conductive tip exposed from one end of the input device. The connection part includes a metal member having a larger cross-section area than a cross-section area of the conductive tip and which affects signal intensity in response to input device tilt as detected by a touch screen of an electronic device.
