Abstract
Provided is an input device which allows a user to select desired contents more quickly and intuitively in selection of contents. The input device includes: a navigation key manipulated to select one direction among a plurality of directions; a dial unit including a rotating dial wheel; and a control unit which controls movement on a user interface screen of a target device based on one or more direction inputs corresponding to the navigation key and a rotation operation input of the dial wheel, wherein the navigation key and the dial wheel are coupled with each other in a stacked structure.
Claims19
An input device comprising:
- a navigation key manipulated to select one direction among a plurality of directions;
- a dial unit including a rotating dial wheel;
- and
- a control unit which controls movement on a user interface screen of a target device based on one or more direction inputs corresponding to the navigation key and a rotation operation input of the dial wheel,
- wherein the navigation key and the dial wheel are coupled with each other in a stacked structure, and
- wherein the control unit further controls a row movement or a column movement of media contents in a matrix structure on the user interface screen based solely on the direction selected by the navigation key, independently from the rotation operation input of the dial wheel.
An input device comprising:
- a navigation key manipulated to select one direction among a plurality of directions;
- and
- a dial unit including a rotating dial wheel,
- wherein the dial unit comprises:
- a dial tooth wheel which is installed on one side of the main PCB assembly where a plurality of first switches for direction detection are installed around a first hole, and which has a second hole and a plurality of gear teeth formed on the outer surface thereof;
- a dial body which has a third hole and a first insertion hole formed around the third hole;
- and
- the dial wheel which has a fourth hole and which is coupled with the navigation key through a first coupling member, and
- wherein the dial body, the navigation key, and the dial wheel are stacked on a cover body installed on the other side of the main PCB assembly by the medium of a key pad having a plurality of actuators formed around a fifth hole.
