Integrating Gesture Recognition and Direct Manipulation.

摘要: A gesture-based interface is one in which the user specifies commands by simple drawings, typically made with a mouse or stylus. single intuitive gesture can simultaneously specify objects, an operation, and additional parameters, making gestures more powerful than "clicks" "drags" of traditional direct-manipulation interfaces. However, problem most gesturebased systems that entire must be entered interaction completed before system responds. Such makes it awkward to use for operations require continuous feedback. GRANDMA, tool building applications, overcomes this shortcoming through two methods integrating gesturing direct manipulation. First, GRANDMA allows views respond clicks drags (e.g. widgets) coexist same interface. More interestingly, supports new two-phase technique, collection phase immediately followed manipulation phase. In its simplest form, transition indicated keeping still while continuing hold button down. Alternatively, occur once enough has been seen recognize unambiguously. The latter method, called eager recognition, results smooth natural interaction. addition describing how integration manipulation, paper presents algorithm creating recognizers from example gestures.
