Abstract: A portable communication apparatus suitable for integration into a garment includes a host unit, an interface and an interactive communication unit. The host unit comprises a removable host device which can be docked into a docking station located in, e.g., the torso area of the garment, and may also be used in a standalone fashion when undocked. The host unit is connected to the interactive communication unit through an interface, which may be a wired or wireless interface. The interactive display unit is preferably located at the end of the sleeve, and may include a graphical display device, a microphone, a speaker, and/or user-activated buttons. The host device may act as a pager as well as perform other functions, and may be replaced with another host device in the docking station having different function and features. The host unit may have a data port, which may be used to connect a remote speaker located in another area of the garment, such as the collar, near the wearer's ear.
