Abstract: A switch device may include a non-conductive operating portion provided with a plurality of operating areas inside an outer edge part of the operating portion, an electrode sheet spaced from the operating portion and having a plurality of electrodes each including at least one detection electrode and being arranged to face a respective operating area, and a detecting unit that may detect operations of the plurality of operating areas. An inner part of the operating portion positioned inward of the outer edge part may be displaceable in a facing direction of the operating areas and the electrodes. The detecting unit may be configured to determine an operated operating area, which may be operable by touch or push operation, based upon a position of at least one of the detection electrodes, a change in capacitance of the detection electrode, and a changing amount in capacitance of the detection electrode.

Abstract: A navigation system and method for guiding a vehicle along a selected route of travel to a destination from a starting point using a display unit. In the navigation system, a positional relationship between a start road branched from a first known branching point (a start intersection from which a guidance of the vehicle along the selected route of travel is initiated) and entrance direction of the vehicle toward the first known branching point is clearly and distinguishably displayed on the screen of the display unit after the selection of the route of travel from the starting point to the destination so that the vehicle can corectly enter the start road at the first known branching point even if it has reached the first known branching point via any arbitrary route of travel from the starting point.
