Abstract: A mechanical vibrator is provided. The vibrator includes a drive, a shaft connected to the drive, and a weight connected to the shaft. The drive is adapted to rotate the shaft and the shaft is adapted to bend during rotation.

Abstract: The invention relates to an electronic device and a method of managing a virtual keyboard of the electronic device. The device comprises a touch pad (106), a processing unit (600) and a feedback unit (612), which provides tactile feedback unit (612) for the user. The processing unit (600) is configured to determine a virtual keyboard (104) for the touch pad (106) and a tactile appearance of the keyboard (104), receive information generated by the pressing of a keyboard (104) key and identify the key that was pressed on the basis of the information. The processing unit (600) is further configured to collect information on the key presses and carry out an analysis of them, and re-determine the tactile appearance of the keyboard (104) on the basis of the collected information and the analysis carried out so as to make the keyboard more ergonomic for the user, which makes it easier to use the keyboard (104) and/or the pressing of a wrong key less likely.

Abstract: Control signals for a process displaying graphical objects in a display are generated with a first control surface, a second control surface and detector means. The first control surface is available for manipulation with a thumb of one hand on one side of a hand-held electronic device. The second control surface is adapted for manipulation with another finger of the same hand. It is located on a different side of the hand-held electronic device. The detector means jointly detect how the first and second control surfaces are manipulated, and convey information about detected manipulation of the first and second control surfaces further to generation of the control signals.
