1. A method for reporting touch on a touchscreen, the method comprising:
detecting first touch data from the touchscreen corresponding to a first touch on the touchscreen;
determining coordinates of the first touch from the first touch data;
reporting the coordinates of the first touch at a first time;
determining, using a trained machine learning model, predicted coordinates of a second touch based on a linear regression of historical touch data, wherein the trained machine learning model is obtained by training, using supervised learning, a machine learning model with the historical touch data, the training comprising building a machine learning model from the historical touch data, updating the machine learning model by comparing predicted touch data with actual touch data obtained by the touchscreen, storing the updated machine learning model as the trained machine learning model in response to determining that a predicted accuracy of a next touch is greater than a predetermined threshold; and
reporting the predicted coordinates of the second touch at a second time, wherein the second time occurs after the first time.
