Finger tracking to write on or correct mistakes on physical documents

A method for providing contact-minimized interaction with smart device, said method comprising:

• sensing, at the smart device, one or more finger movements of one or more fingers of a user;
• identifying, at the smart device, a document associated with the one or more finger movements;
• activating, at the smart device, a Doppler millimeter-wave radar transmitter;
• transmitting, from the radar transmitter, a radar field;
• prompting, by the smart device, the user to write within the radar field an authentication passcode;
• receiving, at a radar receiver, Doppler radar reflections from at least one object within the radar field;
• digitizing, at the smart device, the Doppler radar reflections;
• processing, at a digital signal processor (“DSP”) at the smart device, the Doppler radar reflections;
• identifying, at the DSP, at least one target of the one or more fingers, wherein the at least one target is all or a portion of the at least one object;
• resolving and analyzing, at the DSP, movement of the at least one target;
• translating, at the DSP, the movement of the at least one target into gestures, words, numerals, or symbols, the gestures, words, numerals, or symbols including a double deliberate finger gesture when any of the document is inaccurate, a triple deliberate finger gesture to cancel the contact-minimized interaction with the smart device, and a prolonged single deliberate gesture to override the contact-minimized interaction with the smart device thereby enabling the user to manually enter data into a data entry field;
• sending, from the smart device to an authentication server, the gestures, words, numerals, or symbols;
• authenticating the document, at the authentication server, by matching the gestures, words, numerals, or symbols to gestures, words, numerals or symbols associated with an authentication passcode of the user;
• informing, by the authentication server, the smart device when the user has correctly provided the authentication passcode;
• deleting, at the smart device, any inaccuracies in the document;
• making, at the smart device, one or more corrections to the document;
• storing, at the smart device, the document;
• using, at the smart device, an intelligent bulk data entry engine in synchronization with a data entry orchestration engine to learn a data entry pattern from the gestures, words, numerals, or symbols using deep learning and tiny machine learning (“ML”);
• transmitting, from the smart device to an external user interface (“UI”), the document, based on the data entry pattern;
• displaying, at the smart device, a plurality of document transaction options for the document, in response to the user correctly providing the authentication passcode;
• selecting, at the smart device, at least one document transaction through at least one gesture in the radar field;
• and
• processing, at the smart device, the at least one document transaction.
