Input device and input method

An input device comprising:

• a touch sensor disposed in the input device, the touch sensor configured to detect a gesture made as a touch by a user, and to output electrical signals indicative of changes on a display disposed in a vehicle separated from a user interface (UI) of the output device;
• and
• a processor which causes the display to display a first menu in response to the detected gesture, wherein the first menu extends in a first direction, includes a plurality of regions that are adjacently aligned in the first direction, and includes a plurality of icons, each of the plurality of icons being disposed within each of the plurality of regions,
• wherein the processor causes the display to display a first gauge bar,
• wherein the first gauge bar is configured to be superimposed over one or more of the plurality of regions of the first menu based on a length of a first gesture input to the touch sensor along the first direction,
• wherein the first gauge bar is configured to extend in the first direction from a first reference position on the first menu, the first reference position being an origin of the first gauge bar,
• wherein the first gauge bar has an end portion that extends from the first reference position and overlaps one of the plurality of regions of the first menu,
• wherein a length of the first gauge bar is modified corresponding to a length of the first gesture input to the touch sensor in the input device along the first direction,
• wherein the length of the first gauge bar increases in length in the first direction while the first gesture input is being moved along the first direction,
• wherein the first gauge bar is displayed in a color different from a color of the plurality of regions of the first menu while the first gesture input is being moved along the first direction,
• wherein, when causing the display to display the first gauge bar, the processor causes one icon of the plurality of icons provided on the first menu to be superimposed over the end portion of the first gauge bar when the end portion of the first gauge bar overlaps a region of the first menu including the one icon, and
• wherein the processor selects the one icon that is superimposed over the end portion of the first gauge bar when an input indicating confirmation is provided to the touch sensor.
