| Research Abstract |
We studied both on creating a software system for outputting graphs on a tactiledisplay, and improvements of estimation methods used in this software. This software is a handwriting input system for graphs in high school mathematics. Handwritten curves are recognized their curve types and curve parameters are given at the same time. After that, these graphs are send to tactile display. We use estimation methods using generalized Choquet integral and a rank-based estimation method. We also have improved these estimation methods.
