DEVICE FOR USER INTERFACE USING ROTATABLE INPUT DEVICE AND METHOD OF OPERATING USER INTERFACE

摘要

Provided are a device for a user interface for efficient navigation and a method of operating the device interface. The device for a user interface includes a rotatable input device which is manipulated by a user, a contact detection device which detects whether the user contacts the rotatable input device and generates a first input signal if it is detected that that the user contacts the rotatable input device, a rotation detection device which detects a rotation of the input device and generates a second input signal if the rotation of the input device is detected, and a control device which performs a first operation based on at least one of the first and second input signals.
