Abstract

An electronic device can include a touch sensitive display screen and a controller circuit. The touch sensitive display screen identifies a location where a user is pressing and generates a force signal that indicates how hard the user is pressing. The controller circuit controls a speed at which information items are scrolled across the screen and controls a tilt angle of the displayed information items responsive to the force signal. The controller circuit graphically renders the tilt angle on the screen by tapering width of the displayed information items in a defined direction and regulates the tapered width responsive to the force signal. No tilt angle is rendered when the force signal indicates that the user is not pressing the screen. The scrolling speed and the tilt angle of the displayed information items are increased, to provide a visual indication to the user of the increased scrolling speed, responsive to the force signal indicating that the user is pressing harder against the screen.
