October 20, 2014 at 19:52Gesture recognition in sketchometry
This note is an appendix to the article “sketchometry - dynamic geometry in a browser” . There I was asked to write in more detail about the gesture recognition method used in sketchometry.
There is a family of handwriting recognizers developed at the University of Washington for rapid prototyping of gesture-based user interfaces.
The table shows their names, authors and links to information pages.
On each of the pages you can download the implementation in JavaScript and C #, as well as pseudocode.
In addition, there is a demonstration of work on all pages.
Finally, there are links to publications.
Not being a specialist in handwriting recognition,
I won’t even take up the translation. But there is everything you need to start dating
on these three pages.
So, sketchometry uses $ N Multistroke Recognizer.
