Abstract: An example method includes associating a first area of a non-display area of a touch-sensitive display with a first control, wherein a touch associated with the first control results in moving an indicator through the information in a first direction and in a second direction. The method may also include associating a second area of the non-display area with a second control, wherein a touch associated with the second control results in moving the indicator through the information in the first direction and in the second direction. The method may also include detecting a first touch associated with the first control, in response to detecting the first touch, moving the indicator in the first direction, detecting a second touch associated with the second control, and in response to detecting the second touch, moving the indicator in the first direction.

Abstract: An example method includes displaying information in a first area of a touch-sensitive display of an electronic device and displaying an enlargement of at least part of the information in a second area outside the first area to replace information displayed in the second area. The method may also include detecting a touch associated with the second area and moving at least one of a first indicator in the first area and a second indicator in the second area in accordance with a touch.

Abstract: An example method includes displaying a first control and a second control, wherein a touch associated with the controls results in moving an indicator through information in a first direction and in a second direction, in response to the detecting a first touch associated with the first control, moving the indicator in the first direction, and in response to detecting a second touch associated with the second control, moving the indicator in the first direction.

Abstract: Methods and systems which may implement buffer swapping are provided. The methods include rendering, onto screen locations of a display screen, data from a memory having a first buffer and a second buffer, each buffer having respective buffer memory locations which correspond to the screen locations of the display screen. The methods can include: rendering first data from the first buffer onto the display screen; writing, to the second buffer, second data based on at least some of the first data from the first buffer by performing at least one of transforming at least some first data and changing corresponding screen locations of at least some first data from the first buffer, by writing at most once to each buffer memory location of the second buffer; and rendering the second data from the second buffer onto the display screen.

Abstract: A method includes detecting movement of a touch on a touch-sensitive display of an electronic device from a first touch location to a second touch location. When the distance between the first touch location and the second touch location meets a first threshold, the second touch location is reported to an application layer of the electronic device. After the first threshold is met, a third touch location is reported to the application layer when movement of the touch from the second touch location to the third touch location is detected and the distance between the second touch location and the third touch location meets a second threshold.
