Abstract

Selectively determining a particular graphical user interface widget to receive focus based upon user-entered directional information. When a user enters information concerning which direction to move the focus of the widgets, such as by manipulating arrow keys, the system uses geometry of a current widget and other visible traversable widgets in combination with the user-entered information to determine the next widget, and it moves the focus to that widget.

Claims

1. A method in a data processing system having a display device for selecting a widget to be displayed with focus from among a set of displayed widgets, comprising:

receiving user-entered directional information indicating a direction of intended movement of focus from a current focused widget;

determining a next focused widget from among the set of displayed widgets based upon the user-entered directional information and positional information for each of the displayed widgets, wherein determining includes;

selecting as the next focused widget, when the directional information indicates movement in a vertical direction, a displayed one of the widgets having a minimum vertical distance and a minimum horizontal distance from the current focused widget, in the vertical direction of movement; and

selecting as the next focused widget, when the directional information indicates movement in a horizontal direction, a widget having a minimum distance from the current widget in the horizontal direction of movement and on an equivalent horizon as the current widget; and

transmitting information for use in displaying the selected widget with focus.

2. The method of claim 1, wherein determining further comprises:

selecting as the next focused widget, when no widget is on the equivalent horizon, a displayed one of the widgets having a minimum vertical distance and a minimum horizontal distance from the current widget in the horizontal direction of movement.

3. The method of claim 1, wherein receiving user-entered directional information comprises receiving the directional information via user-entered voice commands.

4. The method of claim 1, wherein receiving user-entered directional information comprises receiving the directional information without the aid of a pointing device.

5. A method in a data processing system having a display device for selecting a widget to be displayed with focus from among a set of displayed widgets without the aid of a pointing device, comprising:

receiving user-entered directional information indicating a direction of intended movement of focus from a current focused widget;

determining a next focused widget from among the set of displayed widgets based upon the user-entered directional information and positional information for each of the displayed widgets, wherein determining includes;

selecting as the next focused widget, when the directional information indicates movement in a vertical direction, a displayed one of the widgets having a minimum vertical distance and a minimum horizontal distance from the current focused widget, in the vertical direction of movement; and

when the directional information indicates movement in a horizontal direction, selecting as the next focused widget a widget having a minimum distance from the current widget in the horizontal direction of movement and on an equivalent horizon as the current widget and, and when no widget is on the equivalent horizon, selecting as the next focused widget a widget having a having a minimum vertical distance and a minimum horizontal distance from the current widget in the horizontal direction of movement; and

transmitting information for use in displaying the selected widget with focus.

6. The method of claim 5, wherein receiving user-entered directional information comprises receiving user-entered voice commands.
