Summary:
Dr. Hammond's paper entitled 'Gestured Recognition' is essentially an introduction to... well... gesture recognition. The first thing to keep in mind is that a gesture represents the path of the pen. As such gestures must be drawn in a single stroke and in the same direction or they will not match up to other preset or example gestures. This paper discusses a few of the key research done in the field of gesture recognition. It begins with a discussion of Rubine's recognition method which is based on 13 calculated features of a gesture. Next, it outlines Long's quill system, which used a total of 22 features to classify gestures on the fly, and to provide system designers with feedback about the gestures they are using. Finally, Hammond's paper talks about the $1 recognizer developed by Jacob Wobbrock. This recognizer standardizes gestures to make matching between templates and new input a faster process.
Discussion:
Dr. Hammond's paper serves as a great compliment piece to the other papers by each respective author that we {have, will, are supposed to} read during the first week or so of class. The section focusing on Rubine's features was especially helpful to me. My only problem is that it wasn't really made clear that we had to blog about it! Get on that, Paul!
I think it's a nice overview of some well-known algorithms, and it's nice to have them all in one place for quick reference, as you hinted at. I also liked that Rubine's features were discussed in detail, as it makes them easy to understand (and to read, since Rubine's paper is old and fuzzy). My favorite color is Red.
ReplyDeleteI also agree that this paper is summarize well-known algorithm very well.At first time,I didn't understand what is gesture recognition.With help of this paper, I can understand what they do and what I must do.
ReplyDeleteI think the beautiful part of the summary is it has not only showed how these features are defined, but also why tehy are defined, this is a great help for us to extend this idea.
