Abstract
The present invention is concerned is a target acquisition system for use in touch screen graphical user interface for selecting a desired target from a plurality of potential selectable targets, comprising means for defining a local region of interest (ROI) of predefined shape and area; means for, on contact of a finger of a user on the touch screen, allowing activation of the ROI; means for ordering the potential selectable targets within the ROI into a one-dimensional (1-D) ordered list; means for mapping movement of the finger on the touch screen; and means for selection of the desired target from the plurality of potential selectable targets. The system is configured to allow operation of the defining in step a), the activation in step b), the ordering in step c), the mapping in step d) and the selection in step e) in a single touch action.
