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 (310) which is manipulated by a user, a contact detection device (350) 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 (330) 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 (240) which performs a first operation based on at least one of the first and second input signals.
Description
Apparatus for user interface and method of operating user interface This application claims priority from Korean Patent Application No. 10-2007-0039438 filed with the Korean Intellectual Property Office on April 23, 2007, the disclosure of which is hereby incorporated by reference in its entirety. technical field The present invention relates to a user interface, and more particularly to an input device using a ball for efficient navigation, a device for a user interface comprising said input device, a method of operating said user interface And a computer-readable recording medium having recorded thereon a program for executing the method of operating the user interface. Background technique FIG. 1A is a diagram illustrating a prior art input device using a trackball. A conventional input device includes an upper case 102 , a lower case 104 , a ball 106 , an x-axis member 108 a , a y-axis member 108 b , rotation detection sensors 110 a and 110 b , and a switch member 1...
