Abstract: The user taps with free fingers on a surface, the finger-taps are organized in groups of simultaneously occurring taps called combinations of concurrent finger-taps. Successions of combinations of one or more concurrent finger-taps are executed. To distinguish between two successive combinations of simultaneous finger-taps, the user produces them separated by short time intervals. A sensing device detects finger-taps; their location and time of occurrence are acquired. The fingers producing the taps are identified. Combinations of fingers producing concurrent taps are associated to linguistic primitives like phonemes or morphemes. Series of linguistic primitives are converted to vocal speech; this method is called Finger Taps Language Technology.

Abstract: The present invention provides the Free Fingers Typing Technology by fingers tapping on a surface, a technology that allows the user to type, point/select (on the display of a computer or computer-based-device) or play music with bare fingers without keyboard, without display pointing/selecting device and even without computer. The invention provides at least: one methodology to execute the finger movements, one convention to code the finger movements, two techniques to recognize the finger movements, a family of apparatus to optically monitor and recognize finger movements as well as the specifications of a plurality of related computer programs all used with the objective of interpreting finger-surface taps and converting them into computer characters, keyboard key strokes, functions of display-pointing/selecting device, music notes etc. . . .

Abstract: The present invention provides the main elements and the essential description of the Extended Free Fingers Typing Technology. The user taps with free fingers on a surface. The hands and fingers are in the pianist position and produce finger-taps organized in groups of simultaneously occurring taps called combinations of concurrent fingers-taps. Successions of groups of one or more concurrent finger-taps are executed. FFTT makes use of a device called FFTT sensing device able to help FFTT system to sense finger-taps and to recognize which fingers produced the taps. Based on appropriate technology FFTT sensing device helps FFTT acquire the data related to the occurrence of each finger-tap event including the location and the time of occurrence. In order for FFTT system to distinguish between two successive combinations of simultaneous finger-taps, the user produces them separated by short time laps.
