Input apparatus and display control apparatus
In an input apparatus, a display portion displays a plurality of function items on a screen to form a plurality of rows that are parallel in a predetermined row direction. The function items are provided with selection regions, respectively. One of the selection regions is selected, using a pointer according to a predetermined selection manipulation, and is determined according to a predetermined determination manipulation. When a first function item in a first row of the plurality of rows is selected, a selection region of the first row is enlarged in a direction directing at a row next to the first row.
1. An input apparatus comprising:
a display portion to display a plurality of function items on a screen;
an input portion to
input an input value to move a pointer that conducts a movement of a pointer on the screen,
perform a selection to select one of a plurality of selection regions provided to the plurality of function items, respectively, using the pointer according to a predetermined selection manipulation, and
determine the selection according to a predetermined determination manipulation; and
a control portion to control the movement of the pointer based on the input value from the input portion,
wherein:
the function items are arranged to form a plurality of rows parallel in a predetermined row direction; and
when the pointer is moved from a selection region of a first function item that is selected as a present selected function item,
the control portion
calculates coordinate distances between the pointer and each of neighboring function items contained in the first row and a second row that is next to the first row,
calculates an amended distance that is obtained by subtracting by a predetermined amendment quantity from only the coordinate distances between the pointer and each of the neighboring function items contained in the first row, and selects as a next selected function item a function item that has a shortest distance among the coordinate distances and the amended distances.
2. The input apparatus according to claim 1 , wherein:
the control portion predetermines the amendment quantity used in calculating the amended distances, according to a direction of the movement of the pointer.
3. The input apparatus according to claim 2 , wherein:
the control portion predetermines the amendment quantity greater as the direction of the movement of the pointer is more parallel with the predetermined row direction.
4. The input apparatus according to claim 1 , wherein:
the input apparatus is mounted in a vehicle; and
the control portion predetermines the amendment quantity greater as a velocity of the vehicle or a vibrating of the vehicle is greater.
5. A display control apparatus cooperating with a display portion and an input portion, the display portion displaying a plurality of function items on a screen, the input portion inputting an input value,
the display control apparatus comprising:
a function item display section to cause the display portion to display the plurality of function items on the screen as being arranged to form a plurality of rows parallel in a predetermined row direction;
a selection region setup section to set up a plurality of selection regions that are provided to the plurality of function items on the screen of the display portion, respectively;
an input value processing section to process the input value inputted by the input portion to move a pointer that conducts a movement to move on the screen;
a selection section to select one of the plurality of selection regions that are provided to the plurality of function items, respectively, based on the movement of the pointer; and
a function item selection section to calculate coordinate distances and an amended distance when the pointer is moved from a selection region of a first function item that is selected as a present selected function item,
the coordinate distances being calculated between the pointer and each of neighboring function items contained in the first row and a second row that is next to the first row,
the amended distance being calculated that is obtained by subtracting by a predetermined amendment quantity from only the coordinate distances between the pointer and each of the neighboring function items contained in the first row,
the function item selection section further selecting as a next selected function item a function item that has a shortest distance among the coordinate distances and the amended distances.
