Abstract
A method of and system for providing accessibility for digital ink is carried out by detecting digital ink input on a user interface (UI) screen, the digital ink input being received via a writing instrument used by a user within a given time period; capturing an image of the digital ink input; examining the image of the digital ink input to detect tremors in the user; assigning a level to the tremors based on discontinuities or irregularities in the digital ink input within the given time period; determining based on the level that the digital ink input requires correction; and applying a correction to the digital ink input to correct the digital ink input.
