Embodiment Construction

[0037] turn first figure 1 , provides a schematic plan view of a mobile phone handset 10 employing a touch screen 12 as a user interface and allowing a portion 12 of an overall larger text document to be displayed on it at any time.

[0038] In settings the display area 14 is used to indicate for example the operating mode, signal strength and current time and the right and bottom border areas of the screen include scroll bars 16 and 18 which allow vertical or horizontal movement of the displayed text portion 12' Next, the screen 12 has the usual functions. The scroll bars are arranged to provide vertical or horizontal movement of the displayed text image represented by arrows A and B respectively.

[0039] Typically, the displayed text portion 12' actually forms an overall larger text document 12" (eg figure 2 In the case of the part shown), the need for scroll bars 16 and 18 arises.

Abstract

The present invention provides for a touch screen including control functionality through touch and movement of a digit of a user's hand over a defined path, and arranged to have the path selectively defined by the user's movement of a screen-engagement member and for example to define the location of such as a digit or stylus scroll bar, and to a hand-held electronic device employing the same over the surface of the screen.

Description

technical field [0001] The present invention relates to touch screens, and in particular (but not exclusively) to handheld electronic devices employing such screens, and also to methods for providing such screens. [0002] Priority is claimed from UK Patent Application No. 0905106.1 filed 25 March 2009 and is hereby incorporated by reference in its entirety. Background technique [0003] Touch screens (whether operated in conjunction with, for example, a stylus or fingers of a user's hand) have been widely used as combined displays and user interface devices for various electronic devices providing display functions. More remarkably, such screens have been demonstrated in recent years on handheld devices such as mobile phones and PDAs. [0004] The user can simply interact with such a device by simply touching the screen with a finger and also by sliding the finger on the screen, for example. The user can then make a selection of, for example, an icon displayed on the scre...
