A wearable display interface (10) that during operation is in short-range (preferably no more than 10 meters), wireless bidirectional communication with a server, related methods, and systems including the interface and server. The wearable interface includes a power supply driving a processor (genera! purpose or graphics, with or without on-board memory, with or without on-board display and other I/O driver(s)) that is operatively coupled to a visual display and a wireless interface where the interface further includes an attachment interface for linking the display interface to a user's body, such as wrist or neck, or apparel. The server is preferably a mobile telephone where the display interface is a client. In addition, the interface can further function as a speaker and/or microphone to received and/or accept verbalized data, such as input instructions or communication commands. Intentional distribution of processing across the server and client ensures that the interface maintains a small and efficient form factor.
