Abstract: Method for selecting an element from among a group of elements displayable on a small input surface. The invention relates to a man-machine interface method using apparatuses having a small input surface of the portable telephone type, connected watch or digital tablet. It consists of a means of selecting an element, from a group of elements. The invention makes it possible to input characters of the alphabet but also any other items, ideograms, symbols, actions. For this purpose, the proposed invention uses a screen, a device for locating at least one contact on this screen and a pointing device such as a finger or a stylus. The invention makes it possible to reduce input errors related to the promiscuity of the elements of the usual methods of input of the virtual keyboard type by increasing the size of the areas to be pointed at. The invention does not make it necessary to learn a way of inputting an element beyond the basic principle of pointing and moving this pointer.
