Abstract :
Support system for handwriting has been developed. Users can write beautiful balanced strings by tracing strings projected to a paper. Only two operations are required for the users. (1) Specify 4 corners of the paper in the captured image using a GUI. (2) Type and set strings. We also realized two kinds of functions to automatically correct the projection position of the strings, one is for the paper´s movement during handwriting, and another is for the error in the projection position due to lens distortion, etc. Experimental resu.lts show usefulness of this system.
