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.
