Understanding Gestures (GECKo and GREAT)

Understanding Gestures (GECKo and GREAT)

We are investigating how children create touchscreen gestures in order to improve recognition rates. This has been done in previous work with tools like GREAT and GHoST, but has largely focused on adults’ gestures. Our prior work has demonstrated that children are less consistent than adults when making gestures, leading to lower recognition rates. We plan to develop new methods of characterizing children’s gestures which we can leverage into new, more effective recognition algorithms, as outlined by our study [Shaw et al, ICMI 2016]. We have shown that humans are able to recognize children’s gestures better than machine algorithms [Shaw et al, ICMI 2017], and we are working on improving machine algorithms to improve that gap.
