Abstract: A microphone array (20) senses an audio source (22). An audio processor (34) is responsive to the microphone array (20) to determine a direction (24) of the audio source (22) in relation to a frame of reference (32). The direction (24) comprises an azimuth angle (26) and an altitude angle (30). A wide-angle digital camera system (40) captures at least one wide-angle image. An image processor (44) is responsive to the audio processor (34) to process the at least one wide-angle image to generate at least one perspective corrected image (46) in the direction (24) of the audio source (22).

Abstract: Data in the form of a machine readable optical code 10, such as a bar code, is combined with a delineator 11, which delineator is visible to the unaided human eye. The data includes at least some identifying information that identifies an information contact point.

Abstract: A standalone keyboard (101) for use with computers (102), which keyboard (101) has integral voice recognition capabilities to facilitate both text entry and cursor-movement control. The speech recognition platform (204) may be speaker dependent and/or trainable. The keyboard (101) may have an optional display (112) to facilitate certain training activities. Recognized words are converted (206) in the keyboard (101) into keystroke data that corresponds to keystroke data as would have been output had the corresponding text been entered by an operator using the keyboard keys (107).
