Abstract
A handwriting input apparatus allows erasure of a displayed figure by a simple handwritten input. When all of a sequence of handwriting points H (indicated by black dots in the figure) composing a locus of a single stroke of handwritten input is located within a proximity area (shown by broken lines in the figure) of either primitive figure obj1 or obj2 currently being displayed, this stroke is recognized as specifying an erasure and the portions of the primitive figures obj1 and obj2 which correspond to the sequence of handwriting points H are accordingly erased.
