In this paper the authors put forward quill, a tool for designing gestures for use in pen based applications. quill lets the designer build gestures, then advises the designer (user) as to whether the gestures they have created are easy to distinguish, both for the gesture recognition algorithm and for the humans who will eventually use the software.
Discussion
The most interesting idea not in this paper is the algorithm for determining which gestures might be confused by users. quill itself seems to be a solution looking for a problem, as I cannot think of an occasion where a designer would be designing gestures without being expert enough to check the distinguishability of gestures on their own. Also the question of when to alert users to errors seems to me to be a well covered problem that doesn't really need to be addressed in this paper.
For "determining which gestures might be confused by users", I would like to say, "how to build up the similarity metrices", this is also the part I am mostly interested in, I think it must in the previous paper.
ReplyDeleteAnd I think the goal of this tool is to allow ordinary people to design their own gestures, without any expet experience at all.
what ordinary people would be building gesture recognizing software? iPhone developers?
