In this paper Dr. Hammond describes the need for and the benefits of a sketch recognition workshop in IUI. She outlines the fields and first points to a possible application of sketch recognition technology. Her example, if implemented, would allow students to draw graphs or images in response to test questions and these images could then be graded automatically. This would allow the teacher to give tests with more free response that could be graded in the same time it takes to grade scantron tests.
She also highlights the possibility of making a CAD program which would allow the user to directly draw their input into the program and CAD would parse that input producing a "pretty" image that takes advantage of all the features of CAD.
Programs and systems like these demonstrate the power of sketch recognition. With many programs becoming very difficult to use with just a mouse and keyboard, harnessing the power of sketch recognition could help users get more done quicker. I would no doubt support a workshop on sketch recognition. As mentioned in the paper, the field should be further along than it is. It seems like we almost never hear of anyone working on the problem even though the potential is limitless. Hopefully the workshop gets accepted and we can see some greater successes from other sources as well.

Ah, Dr. Hammond's paper!
ReplyDeleteI didn't read it myself, but it sounds interesting.
I'm not sure I like the idea of taking more free response questions...
The CAD application sounds very practical though.
I would blame the lack of sketch recognition applications on the fact that there's not very many devices that are popular and support sketch recognition.
