Touch Screen & Gestures
A Touchscreen is an electronic visual display that can detect the presence and location of a touch (with finger or hand) within the display area.
The Touchscreen Interface of a tablet gives people a sense of immediate connection with their device and enhances their sense of direct manipulation of onscreen objects.
To press or select an item such as a Call To Action (CTA) or text link.

To scroll slowly down a list or pan across content by moving side to side.

A horizontal gesture, from right to left or vice versa, used to page through content.
Used to scroll or pan quickly, the speed of the gesture affects the speed of the action.
Used to undo or redo an action.
The standard gestures above are recommended by GEL. People are comfortable using them providing services apply them consistently.
Although most tablets are capable of providing support for more complex gestures, these should be used with caution. Too many multi-fingered gestures can confuse. As a general rule, non-standard gestures should not be used for core navigation as this can hide functionality and cause usability problems.
