Summary:
This paper introduces a mathmatics problem solving system which is pen-based and modeless. the system can recognize the equation and solve math equation users draw by hand by converting them into MATLAB. This paper use a gesture-based method to help the recognition of mathmatic expressions.Some useful gestures are developed to support the funtion of editting and commandin.Nailing Diagram Components and Grouping Diagram Components are used to make a diagram.Two kind of association are included : explicit association and implicit association.
Discussion:
In order to implement the function of this system, character recogniton is needed, which is not easy especially when the character set is huge. If its accuracy is good enough, it will be really helpful and be a natural way to use MATLAB with powerful computational ability.
Not just matlab, mathpad2 has already been product, it can be applied to every kinds of mathmatical tools.
