Touch Screen Scroll Speed Modification Based on Finger Touch Points

To scroll through social media sites, users touch a finger to the screen and move it over the screen. This method is when the scroll speed is at the rate of the finger movement. The user has to continue to move the finger back to the original location to scroll through additional information.

Other methods exist that determine the scroll speed by the speed of the scroll, and the scroll gradually slows when the user stops touching the screen. This method is not sufficient because the user loses control of the scroll, the scrolling stops, and the user must to repeat the method.

The novel contribution is a system and method that enable a user of a touch screen to adjust the scroll speed and direction. The system enables the user to touch the screen in a scroll area (i.e., scroll bar) with a first finger (i.e., anchor finger ) and a second finger. The anchor finger is a static placement and the second finger placement determines the direction of the scroll. The distance between the fingers controls the scroll speed such that the greater the distance between the anchor and the second finger, the greater the speed of the scroll is. For example, the scroll speed is faster if the fingers are one inch apart than if the fingers are one-half an inch apart.

The system can analyze the user's hand to determine the maximum finger expansion so that the scroll speed adjustment is proportional to the possible maximum distance between the anchor finger and the second finger.

The system enables the user to continue with the increased sc...
