This paper has built a system Mathpad2 for users to efficiently do mathematical operations. The system will recognize sketch math notations or equations, then give the calculated results. Besides the sketch that user can write to the screen, the system also provide some useful gestures.MathPad also provide set of computational functions to choose from, as well as different colors to help to recognize. Current Mathpad2 can calculate simple equations, but failed to the complicated ones.
Discussion:
As a specific software, the author does not give a lot of details about the algorithm. However, this paper has given a very good application of sketch recognition, and even prompted to a product.
Yes, I found this paper strange, first, he didn't give algorithm, second when I tried to find his implementation, there's no way to download!!!! This suddenly turns my interest down.
