Enhancing Scrolling Of A Page By Utilizing A Single Press Action

Disclosed is a method and system for scrolling of a page in a desired direction by utilizing a single press action on the touch-sensitive display of a mobile computing device followed by a rolling action. The single press may be performed by a user by using one of a finger, a thumb or a side of a palm.

The method and system determines a 3600 (degrees) region surrounding the finger

while a user performs a scrolling action on a page in the desired direction. The 3600 region may be divided into 8 regions as illustrated in Figure 1.

Figure 1

Each of the divided 8 regions, termed as octants, is at an angle of 450. The octants may be referred to as North (N), North East (NE), East (E), South East (SE), South (S), South West (SW), West (W) and North West (NW). While one region is centered on +X axis (00), another region is centered on -X axis (1800). Similarly, other regions are centered on the +Y (900), and -Y (2700) respectively. Further, there are four more regions, each centered at an angle of 450, 1350, 2250, and 3150 respectively.

The disclosed method and system captures the initial position of the finger as a starting point for scrolling to any part of the touch display of the mobile computing device.

According to embodiments of the present invention, the user presses the touch display using the index finger and rolls it slightly to the right to scroll to the left. In another embodiment, the user presses the touch display using the index finger and rolls it slightly to the left to scroll to the right. Similarly, touching and rolling up or down causes the displayed contents to scroll down and up respectively.
