Abstract
Handwriting activity is recorded by use of electromyography (EMG) signals detected from muscles at several locations on the hand. The EMG signals are sensed and registered. The sensed signals are processed and stored, after which the signals are analyzed to reconstruct handwriting activity into a digital format. Machine edible text is generated and displayed along with a graphical depiction of the handwriting.

3. A method for rendering intelligence based on sensed hand movements, the method comprising:
-
sensing electromyography (EMG) signals from the set of sensors;
interpreting the EMG signals to reconstruct a plurality of movements associated with writing activity to render a pattern of strokes corresponding to handwriting activity;
rendering an output from the plurality of movements; and
storing the rendered output. - View Dependent Claims (4, 5, 6, 7)

8. A system for reconstructing handwriting activity to a digital format, the system comprising:
-
a user interface including a glove with a plurality of sensors thereon, including sensors capable of electromyography (EMG) detection of muscle activity in the fingers;
a sense interpreter receiving EMG signals from the sensors as sensed hand movement data;
a unit generating a reconstruction of line movements corresponding to the sensed hand movement data;
a recognition unit coupled to respond to said unit generating a reconstruction of line movements, capable of convening said scribe movements into corresponding computer recognizable codes in said sequential order, each of said codes representing a corresponding textual component. - View Dependent Claims (9, 10, 11, 12)
