Adjusting eraser size in drawing applications

The method includes identifying, by one or more computer processors, a first location and a second location of input on a touch-sensitive surface. The method further includes calculating, by one or more computer processors, a distance between the first location and the second location. The method further includes identifying, by one or more computer processors, a first elapsed time between creation of the identified first location of input and the identified second location of input. The method further includes calculating, by one or more computer processors, a first size of an eraser based upon the identified first elapsed time. The method further includes generating, by one or more computer processors, an eraser path based upon the identified first location and the identified second location of input on a touch-sensitive surface, and the calculated first size of an eraser.
