A system and method is disclosed for reconfiguring the graphical user interface (GUI) of a mechanically vibrated touchscreen display associated with a portable mobile communications device that is operable in a variety of modes. The reconfiguration of the GUI is based on the orientation of the portable mobile communications device. An orientation sensing mechanism senses whether the portable mobile communications device is currently in a portrait or landscape orientation. An orientation sensing application accesses an orientation profile that associates each mode of operation with either a portrait or landscape orientation and determines which mode of operation is the default mode for the sensed orientation of the portable mobile communications device. The GUI of the mechanically vibrated touchscreen display is then reconfigured for the default mode of operation.

A position sensor using a novel optical path array (OPA) element, an angle-selective spatial filter, and an imaging array is capable of measuring the translation and orientation relative to a target member in X, Y, Z, yaw, pitch, and roll (“6D”) simultaneously, and with high precision. A target member includes an array of target points surrounded by a contrasting surface. The position sensor uses the OPA element in combination with the angle-selective spatial filter in a target point imaging arrangement such that the imaging array of the position sensor only receives light rays that enter the OPA element according to an operable cone angle α. Accordingly, each target point generally produces a ring-shaped image having a size on the imaging array that varies with the Z position of each target point. The X-Y position of each target point image on the imaging array varies with the X-Y position of each target point. Accordingly, three or more target point images analyzed in the same image are usable to determine a 6D measurement relative to the target member. X and Y displacement of the target member can be accumulated by known methods and the other 6D measurement components are absolute measurements at any position.
