  • Patent number: 10409449
    Abstract: An in-vehicle display apparatus includes a control unit for executing a selected application feature for controlling a control object device. The selected application feature may be one of a plurality of application features that is selected by a driver by using switches on a portion of a vehicle steering wheel. The in-vehicle display apparatus displays output contents of the application feature in a main display area together with vehicle information. When no operation is performed for controlling the application feature for a predetermined period of time, or when the driver selects an other application feature, the control unit executes the application feature that is currently running in a background, treating it as a background (BG) application feature, and displays a BG icon for a BG application feature associated switch that is operable for an operation of the BG application feature that is currently running in the background.

  • Patent number: 9323419
    Abstract: An input apparatus includes a display unit, an input unit, and a control unit. The display unit displays function items on a display window.

The control unit controls a movement of the pointer by setting coordinates of the pointer based on position information transmitted from the input unit. Each function item includes a button region and a selection region. When the pointer moves to one of the button region and the selection region, the function item is selected. When the pointer is set to an equivalent stop state in the selection region, coordinates of the pointer are set as coordinates of a stop state position. When the pointer is set to the equivalent stop state in the button region, the coordinates of the pointer are set as coordinates of a predetermined position of the button region.

  • Patent number: 9189094
    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.

  • Patent number: 9134831
    Abstract: An input apparatus for, in response to a user's sliding operation on an operation surface, inputting a coordinate point in the operation surface to move a pointing image to a target button image is disclosed. The apparatus acquires the coordinate point in the operation surface and sets, as a characteristic line, a tendency of trace of the coordinate point in the user's sliding operation directed to a lateral direction or a longitudinal direction of the operation surface. The apparatus corrects the coordinate point with reference to the set characteristic line so that the trace of the coordinate point is corrected to be a horizontal line or a vertical line. The apparatus outputs the corrected coordinate point for moving the pointing image.
