Dr Beryl Plimmer has provided us with her presentation notes from her CULM lecture.
Sketches have, since at least the time of the cave men, been used to externalize
and communicate ideas. Sketching out an idea is helpful when problem solving
by oneself – it is also a well proven way to communicate with others. The use of
computer tools has disrupted the role of sketching because digital documents
have the advantages of easy storage, transmission and editing.
The computer hardware that makes sketching possible is now readily available.
However for sketching to regain its rightful place as a problem solving tool, the
digital sketches must be ‘understood’ by the computer. Once the software
understands the sketch, usual functionality such as intelligent editing is possible.
In this talk I will describe how we compute features of digital ink and then use
data mining techniques to recognize the ink.
