Abstract: Computer implemented techniques for converting a text string to an interactive media. The techniques cause a data processing system to receive a text string having one or more branching moments, process the text string to recognize indications of the one or more branching moments given the text string, convert the processed text string and the indications of the one or more branching moments into executable computer code, receive a response to a given one of the converted one or more branching moments from a predetermined set of responses, generate, from the executable computer code and media elements for the response, a virtual respondent, and store the executable computer code and the media elements as a file in the computer storage that represents the virtual respondent.

Abstract: A system and process for capturing and rendering ink is described. An ink canvas object may contain none, one, or more objects or elements and may specify the z-order of the objects or elements. The ink canvas object may host a variety of objects or elements and, therefore, provide ink functionality to the objects or elements, even though the objects or elements themselves may not have ink functionality. The ink canvas object is attached to an ink editor that has an associated modifiable ink editor behavior, whereby ink specific behaviors are collected in the ink edit behavior.

Abstract: A system and method for erasing ink is described. Using an erasing contour, the system determines closest points which come close to or contacts the erasing contour when it encounters an ink stroke. Portions of an ink stroke may then be erased when the erasing contour contacts the ink stroke.
