Abstract: A wearable display interface that during operation is in short-range, 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 that is operatively coupled to a visual display and a wireless interface where the wearable display 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.

Abstract: A voice language translator, suitable for implementation in hand-held size, is disclosed. The voice language translator includes: a key pad (20); a display system (17); a language cartridge(s) (45); a voice recognition module (49); a voice synthesizer (47); a speaker (39); a microphone (41); and a programmed CPU (43). Prior to use as a translator, the voice language translator is trained to the voice of a user. During training, a series of words and phrases to be spoken by the user are displayed, or spoken, in the language of the user. As the user speaks the words and phrases, the voice recognition circuit produces a digitally coded voice pattern that uniquely identifies the way in which the user spoke the words and phrases. The voice patterns produced by the voice recognition circuit are analyzed and stored, preferably in the cartridge.
