Recognition system for recognizing multiple inputs of gestures, handwriting symbols and virtual keys on touch screen

A recognition system for recognizing multiple inputs of gestures, handwriting symbols and virtual keys on a touch screen comprising:

• the touch screen serving to receive a touch action of a user for generating a plurality of touch signals;
• the touch screen being a touch panel of an electronic device;
• a touch IC connected to the touch screen;
• the touch IC serving to receive the touch signals from the touch screen and to convert the touch signals to a touch data frame which has a 2D (two-dimensional) structure formed by a plurality of touch data items;
• a processor set connected to the touch IC and an OS (Operating System);
• the processor set serving to receive the touch data frame from the touch IC and to perform a touch data processing on the touch data frame;
• the touch data processing being performed by using a processing directly executed by the OS and a processing of AI (artificial intelligence) recognizing;
• wherein in the touch data processing, when the touch data frame corresponds to a plurality of second inputs and a number of the second inputs is larger than or equal to the predetermined number, the touch data frame is viewed as a data frame which is not capable of being directly processed by the OS and is outputted to a AI (artificial intelligence) recognition module for recognizing the touch data frame;
• the AI recognition module is connected to the processor set;
• an AT recognizing result outputted by the AI recognition module is outputted to the processor set;
• when the AI recognizing result is corresponded to a plurality of specific key inputs, the processor set performs a grammar correction on the specific key inputs and a result of the grammar correction on the specific key inputs is outputted to the OS for processing;
• when the AI recognizing result is corresponded to at least one specific handwriting symbol including a character string or a mathematical expression, the processor set performs a symbol correction on the at least one specific handwriting symbol and a result of the symbol correction on the at least one specific handwriting symbol is outputted to the OS for processing;
• when the AI recognizing result is corresponded to a specific operation gesture, the processor set outputs the specific operation gesture to the OS for processing;
• wherein in the touch data processing, the touch IC serves to perform an initial processing;
• the initial processing is that the touch IC receives the touch signals from the touch screen and converts the touch signals to the touch data frame;
• a preprocess unit connected to the touch IC;
• wherein in the touch data processing, the preprocess unit serves to receive the touch data frame and to perform a noise filtering, a normalization and a data splitting on the touch data frame;
• and
• the touch screen serving to display a virtual keyboard or a part of the virtual keyboard for being viewed by the user and receiving the touch action of the user.
