System for applying application behaviors to freeform data

摘要

A freeform display editing system groups freeform strokes into one or more segments on a display. Each segment in the system defines a region of the display that includes a collection of strokes. Multiple behaviors can be dynamically attached or removed from any given segment, even after a segment has been created and filled with strokes. Each behavior provides a task-specific application to the segment to which it is attached. Segments de-couple interpretations of input data from behaviors to provide temporal multiplexing of task-specific applications. Advantageously, data associated with a segment can be composed at the same time by different behaviors.
