Abstract
An image forming apparatus to provide a visual feedback in response to a manipulation of a navigation key includes a display panel unit, a navigation which is selectable and rotatable, to perform a menu navigation over the display panel unit according to at least one of a selection and a rotation thereof, a state indicating unit to operate in a display pattern to correspond to a manipulation state of the navigation key, and a control unit to control the state indicating unit according to the manipulation state of the navigation key. As a result, a direct, instant, and visual feedback is provided.
Claims22
An image forming apparatus, comprising:
- a display panel unit;
- a navigation key which is selectable and rotatable, and to perform a menu navigation over the display panel unit according to at least one of a selection and a rotation thereof;
- a state indicating unit to operate in a display pattern to correspond to a manipulation state of the navigation key;
- and
- a control unit to control the state indicating unit according to the manipulation state of the navigation key.
An input panel apparatus, comprising:
- a navigation key which is selectable and rotatable, and to perform a menu navigation according to at least one of a key selection and a rotation range, the navigation key having one or more push areas provided on at least one portion thereof;
- and
- a state indicating unit including a plurality of light emitting elements (LED) arranged along an edge of the navigation key, to operate in a display pattern in accordance with a manipulation of the navigation key.
A method to provide a feedback in response to a user manipulation of an image forming apparatus including a navigation key which is selectable and rotatable, and a plurality of light emitting elements (LED) arranged along an edge of the navigation key, the method comprising:
- determining a display pattern to correspond to a key manipulation or a change in the state of the image forming apparatus, if the navigation key is manipulated, or if the state of the image forming apparatus is changed;
- and
- providing a feedback in response to the manipulation of the navigation key, by turning on or off the plurality of LEDs according to the determined display pattern.
