1. An apparatus comprising:
- a touch screen configured to display information and to output a touch position signal indicative of the position where the touch screen has been touched by a user;
a touch pressing force sensor configured to output a force signal indicative of the force with which the touch screen is pressed by the user while touching the touch screen; and
at least one processor configured to receive the touch position signal and the force signal and to detect the presence of following determinations;
the touch position signal indicates that the user has stroked on the touch screen according to a predetermined track; and
the force signal indicates that the user has applied on the touch screen a force according to a predetermined pattern, which pattern contains at least one change that exceeds a predetermined threshold.

Abstract
Locking or unlocking of a user input of a portable device is detected from the way in which a user has stroked her finger on a touch screen. The stroke is checked for two different determinations which require that the touch screen is touched according to a predetermined track and with a force pattern that has at least one substantial change so as to avoid the need to provide the apparatus with any mechanical buttons at all while providing user-reproducible indication of locking or unlocking of the user input with the touch screen.
