Abstract
A method of interacting with a scrollable area on a portable electronic device is described. In accordance with one embodiment, there is provided a method of interacting with a portable electronic device having a touch-sensitive display, the method comprising: displaying a user interface screen having a scrollable area on the touch-sensitive display; and displaying a transparent scrollbar which overlays elements of the user interface screen when a touch event is detected in a display area corresponding to the scrollable area.
Claims20
A method of interacting with a portable electronic device having a touch-sensitive display, the method comprising:
- displaying a user interface screen having a scrollable area on the touch-sensitive display;
- displaying a transparent scrollbar which overlays elements of the user interface screen when a touch event is detected in a display area corresponding to the scrollable area;
- determining a duration of the touch event;
- decreasing a transparency level of the transparent scrollbar when the duration of the touch event is less than a threshold duration of a touch and hold gesture;
- highlighting the transparent scrollbar when the duration of the touch event is greater than or equal to the threshold duration of the touch and hold gesture;
- and
- redisplaying the user interface screen without the transparent scrollbar when the touch event ends.
A method of interacting with a portable electronic device having a touch-sensitive display, the method comprising:
- displaying a user interface screen having a scrollable area on the touch-sensitive display, the user interface screen having a transparent scrollbar which overlays elements of the scrollable area when a touch event is detected in a display area corresponding to the scrollable area;
- detecting a touch event in a display area corresponding to the scrollable area;
- determining a duration of the touch event;
- decreasing a transparency level of the transparent scrollbar from a default level when the duration of the touch event is less than a threshold duration of a touch and hold gesture;
- highlighting the transparent scrollbar when the duration of the touch event is greater than or equal to the threshold duration of the touch and hold gesture;
- and
- increasing the transparency level of the transparent scrollbar to the default level when the touch event ends.
A portable electronic device, comprising:
- a processor;
- a touch-sensitive display having a touch-sensitive overlay coupled to the processor;
- wherein the processor is configured for:
- causing the display of a user interface screen having a scrollable area on the touch-sensitive display;
- causing the display of a transparent scrollbar which overlays elements of the user interface screen when a touch event is detected in a display area corresponding to the scrollable area;
- determining a duration of the touch event;
- decreasing a transparency level of the transparent scrollbar when the duration of the touch event is less than a threshold duration of a touch and hold gesture;
- highlighting the transparent scrollbar when the duration of the touch event is greater than or equal to the threshold duration of the touch and hold gesture;
- and
- causing the redisplay of the user interface screen without the transparent scrollbar when the touch event ends.

- detecting a touch event in a display area corresponding to the scrollable area;
- determining a duration of the touch event;
- causing a transparency level of the transparent scrollbar to be decreased from a default level when the duration of the touch event is less than a threshold duration of a touch and hold gesture;
- highlighting the transparent scrollbar when the duration of the touch event is greater than or equal to the threshold duration of the touch and hold gesture;
- and
- causing the transparency level of the transparent scrollbar to be increased to the default level when the touch event ends.
