Abstract: A portable navigation device (200) with an ergonomic user interface is described. It includes: a housing (210); a controller (220) coupled to the housing (210), the controller (220) configured to control the operations of a portable navigation device; memory (270), coupled to the controller (220), being operable to store a route; an integrated global positioning system (GPS) receiver (250) in the housing (210), coupled to the controller (220); a display (240) within the housing (210) and coupled to the controller (220), the display (240) viewable from a front (305) of the housing (210); and a paddle control module (310) coupled to a rear portion (315) of the housing (210), configured to control certain operations of the device. The ergonomic design allows a user ease of access, to operate a portable navigation device accurately, intuitively and with minimal distraction, during operation. This structure provides an enhanced user experience.

Abstract: Disclosed is a user interface of a headset that is situated on one or both sides of the headset. The disclosed user interface on two sides of the headset includes two touch-sensitive surfaces that are configured to detect certain gestural motions. The surfaces can detect sliding motions as well as pressure points. Grouping of gestures and movements may provide memory cues for users to remember which side of the headset to use for certain functions. In one embodiment, a first user interface that is situated on one side of the headset can provide communication controls. A second user interface that is situated on the other side of the headset can provide audio controls. In another embodiment, a user interface including a touch-sensitive surface is configured to detect up to six user inputs. Accordingly, two touch-sensitive surfaces may achieve the same amount of control as six buttons.

Abstract: An adapter for a modular wireless communication device. The adapter can include a lanyard, a cradle coupled to the lanyard, the cradle configured to support a short range wireless communication module, the cradle including an audio plug configured to provide a connection to the short range wireless communication module when the short range wireless communication module is coupled to the cradle, a microphone coupled to the lanyard and the audio plug, and a speaker coupled to the lanyard and the audio plug.
