Abstract: A device with a user interface includes a display screen, input keys, and a controller that is configured to control the display screen to display a three by three matrix of fields wherein each of the fields may contain a symbol, and wherein the controller is further interfaced with a number of the input keys, for example four selection keys or eight selection keys, in such a way that one of the symbols is selected by operation of at least one of these selection keys and some of the symbols are selected by simultaneous operation of two or more of the selection keys.

Abstract: An apparatus for selection of characters to be displayed on a display screen. Has input actuators with associated fields containing graphical symbols representing the characters. The user is guided during selection of a character via the display. The selection procedure is sufficiently simple to allow a user to memorise the steps needed in order to select a specific character. Uses a limited number of actuators, and a character is selected using a sequence of actuations. Actuations may e.g. be keystrokes or movement by tactile pointing means on a touch sensitive device. Preferably, a character is selected by drawing one or two linear segments on a touch sensitive device. The displayed graphical symbols are preferably rearranged upon actuation. Suitable for use in electronic devices, in particular hand held devices having a small display screen, such as communication equipment, such as portable phones, e.g. mobile phones, or computers.

Abstract: The invention relates to a man-machine interface wherein three-dimensional positions of parts of the body of a user is detected and used as an input to a computer. An electronic system is provide for determining three-dimensional positions within a measuring volume, comprising at least one electronic camera for recording of at least two images with different viewing angles of the measuring volume, and an electronic processor that is adapted for real-time processing of the at least two images for determination of three-dimensional positions in the measuring volume of selected objects in the images.
