Device and method with trained neural network to identify touch input

An electronic device comprising:

• a touch screen;
• at least one memory storing at least one instruction;
• and
• at least one processor operatively connected to the at least one memory and configured to execute the at least one instruction to:
• acquire, for a plurality of fingers of a user, a plurality of first images corresponding to a first type touch input for touching the touch screen with a pressure less than a predetermined pressure, and a plurality of second images corresponding to a second type touch input for touching the touch screen with a pressure greater than the predetermined pressure, the second type touch input having a greater area of a region corresponding to a touch input than the first type touch input, wherein the acquiring the plurality of first images and the plurality of second images comprises:
• displaying, on the touch screen, a first user interface (UI) element for guiding the first type touch input and a second UI element for guiding the second type touch input, wherein a size of the second UI element is greater than a size of the first UI element;
• based on detecting a user touch input for touching the first UI element, generating the plurality of first images;
• and
• based on detecting the user touch input for touching the second UI element, generating the plurality of second images;
• train a neural network model for identifying a type of the user touch input of the user based on the plurality of first images and the plurality of second images, to obtain a trained neural network model;
• based on acquiring the user touch input through the touch screen, acquire a plurality of input images corresponding to the user touch input;
• identify the type of the user touch input by inputting, to the trained neural network model, the plurality of input images, the plurality of first images, and the plurality of second images;
• based on the type of the user touch input being the first type touch input, perform a first function;
• and
• based on the type of the user touch input being the second type touch input, perform a second function different from the first function.
