Abstract: It is presented a method for providing a user interface of a portable electronic apparatus. The method comprises: detecting an actuation of a mode switch actuator associated with switching operational modes of the apparatus; determining a switching direction by determining whether the actuation is associated with a first switching direction or a second switching direction; determining a current operational mode; determining a new operational mode considering the switching direction and the current operational mode; and switching operational modes of the portable electronic apparatus from the current operational mode to the new operational mode. Corresponding portable electronic apparatuses and computer program product are also presented.

Abstract: A user input system for an electronic device including an input actuator adapted to be depressed by a user to input a signal into the electronic device; and an actuator location signaling system adapted to signal location of the input actuator to the user. The actuator location signaling system includes a textured surface proximate the input actuator for a finger of the user to contact, and a system for moving the textured surface to enhance sensory input to the user's finger while contacting the textured surface.
