Manipulating history in generative hypermedia
Additional Document Info
We continue to develop a generative hypermedia system that uses composition for browsing, collecting and organizing information samples from web pages. The system's generative actions of collecting information samples and composing them visually are conducted iteratively over time, based on an adaptable user model. The system presents the ongoing generation of the composition to the user in an interactive information space. In this space, the user can directly manipulate the composition through interactive design operations, and affect the model by expressing positive or negative interest in each sample. We are developing mechanisms for manipulating the time-based medium of the evolving information space. Interaction design affords linear timeline traversal and non-linear time travel. Extended tape recorder metaphor controls, including jog-shuttle based navigation, provide the user with flexible means for operating the system's generative functionalities, and linearly traversing session history. We introduce a door-latch metaphor that enables one of several considered forms of non-linear time travel. Users can change history by retroactively locking an information sample in position across time.
