Abstract: A method for selecting a symbol using an M-key keyboard in a personal information device (PID) divides the M keys into a first key group and a second key group. Each symbol to be recognized from the input key-strokes on the keyboard is assigned a unique two-keystroke sequence in which the first key and the second key of that two-keystroke sequence are selected from different key groups. When receiving keystrokes from the keyboard, two-keystroke sequences received from the keyboard are matched to the symbol assignments to derive which symbol is selected. This method is applicable not only for selecting letters from a European alphabet, such as the English or the Cyrillic alphabets, this method is applicable to selecting from a phonetic alphabet, such as the Pin-Yin system for Chinese characters and other phonetic systems in the Korean and Japanese languages as well.

Abstract: A method and system for permitting a user to spatially access and playback time-based information having a plurality of segments. Each of the plurality of segments are mapped to a corresponding one of a plurality of mapped spatial coordinates. A user interface determines an input spatial coordinate corresponding to a portion of a user's body within an input coordinate space. A segment of the time-based information corresponding to the input spatial coordinate is accessed and played back using a playback device. A sensory output which corresponds to the segment is produced for sensing by the portion of the user's body. The sensory output aids the user in obtaining a sense of the whole of the time-based information in the input coordinate space.
Abstract: A personal communications apparatus using a garment-based audio interface. A garment member is worn on the upper torso of a person, wherein the garment member includes a neck opening which allows extension therethrough of the neck of the person. An audio output device capable of producing hi-fidelity spatialized 3-D sound aiming in selected directions is located adjacent the neck opening of the garment member. A receiver capable of receiving at least one transmitted signal and producing an audio signal based thereupon is coupled to the audio output device. An audio input device capable of capturing spatialized 3-D sound from selected directions is located adjacent the neck opening of the garment member. The audio signal from the audio input device is provided to a transmitter capable of transmitting a signal in dependence upon the audio signal. Embodiments of the garment member include a shirt and a necklace.

Abstract: A method and system for accessing time-based information based on spatial coordinate information obtained from a user. Time-based information is mapped into a spatial representation by mapping and transforming the timing of time-based information segments to spatial coordinates. Such spatial coordinates could be either one, two, or three dimensional. With this mapping, segments of time-based information can be associated with different parts of a spatial object, a spatial representation, or different position of a spatial movement. These segments can be accessed by the user by physical inputs in such a fashion that the kinesthetic or touching memory of the user can be relied upon to re-access information and to create a sense of the whole in the information.
