DISPLAY CONTROL APPARATUS AND DISPLAY SYSTEM
First Claim
1. A display control apparatus controls a plurality of buttons displayed on a screen of a display unit, the apparatus comprising:
- a detection unit detecting a contact position on an input plate, wherein the input plate is touched by a fingertip of a user;
a position calculation unit calculating a position of a pointer on the screen, as a pointer position, the pointer position corresponding to the contact position detected by the detection unit;
a button selection unit selecting one button, as a desired button, from among the plurality of buttons on the screen based on the pointer position;
a selected button display control unit displaying the desired button on the screen in a display mode different from the buttons not selected; and
a position correction unit correcting the pointer position to be on or adjacent to a reference line defined on the screen when the pointer position is located within a specific range including the reference line, whereinthe reference line is defined to extend from a previous pointer position calculated by the position calculation unit at a prior predetermined time to a specific direction.

Abstract
A display control apparatus controls a plurality of buttons displayed on a screen of a display unit. The apparatus, via a detection unit and position calculation unit, calculates a pointer position on the screen that corresponds to a contact position on an input screen that is touched by a fingertip of user. A button selection unit selects one button, as a desired button, from among the plurality of buttons on the screen based on the pointer position. A selected button display control unit displays the desired button on the screen in a display mode different from the buttons not selected. A position correction unit corrects a current pointer position to be at a reference line when the reference line extends in a specific direction from a previous pointer position and the current pointer position is within a specific range that is set to include the reference line.

9. A display system comprising:
-
a display unit including a screen for displaying a plurality of buttons; and a display control apparatus controlling the plurality of buttons displayed on the screen of the display unit for displaying one of the plurality of buttons in a manner different from other buttons, the display control apparatus including; a detection unit detecting a contact position on an input plate, wherein the input plate is touched by a fingertip of a user, a position calculation unit calculating a position of a pointer on the screen, as a pointer position, the pointer position corresponding to the contact position detected by the detection unit, a button selection unit selecting one button, as a desired button, from among the plurality of buttons on the screen based on the pointer position, a selected button display control unit displaying the desired button on the screen in a display mode different from the buttons not selected, and a position correction unit correcting a current pointer position based on a previous pointer position provided by the position calculation unit as the pointer position at a predetermined time prior to the current pointer position, wherein the current pointer position is corrected to be at a reference line when the reference line extends in a specific direction from the previous pointer position and the current pointer position is within a specific range that is set to include the reference line. - View Dependent Claims (10)
