Summary:
Long, Landay, and Rowe noticed that people were incorporating new interaction technologies into their user interfaces, but that they did so naively, causing issues with recognition and frustrating users. To alleviate these frustrations in a gesture-based system, they developed quill. quill continuously analyzes gestures and warns designers when they may be confused with other gestures by the computer or users. Long and
company use the same algorithm that Rubine developed to train their system (about 15 examples per class), but focus everything on the designer end.Because quill is giving advice back to designers, Long and company found that the user interface was very important. Their three main areas of consideration were the timing of advice, the amount of advice to display, and the content of said advice. In the end, messages are most often displayed when the designer is testing gestures. They are kept concise, and include hyperlinks to more thorough explanations and solutions. Finally, the messages are written plainly in English to avoid ambiguity and frustration.
Discussion:
Cool story, bro! But really... I liked the idea of giving designers feedback on their purported gestures. Embracing new technologies is great, but if you don't consider users and interpretation in your system design then it's better to not even use the technology! I also liked how part of the paper focused on the feedback system and its challenges. That topic is still of great relevance today, and is something that we all have considered or will consider during our own projects and applications.
I liked how they try to help the user with quick, brief pointers. It's rare for any CS paper to actually consider the user when creating a system. Is there an online demo of this anywhere?
ReplyDeleteThis paper is really great. Since the gesture and pen computing become more and more popular these days. Many domains become perfer to use pen or gesuture insteand of normal input devices. So the first problem must be the gesture design, the more complicated system, the more kinds of gesutres needed, this system is great helpful for this task, espeically this system can give feedback when we are on the designing process. If the design is completed before giving some feedback, it becomes very hard to modify the gesture, chang one can cause many other also changed
