Let’s take a trip to the ICU


(Wild) Bundles


(Wild) Bundles

• manage information for diverse, complex tasks• contain selected, collected, structured, annotated• are often used in settings with:

– high uncertainty– low predictability– potentially grave outcomes– time & attention are highly constrained


(Wild) Bundles

• There is benefit in creating (active processing of information)

• There is benefit in reusing (trigger memory)

• There is benefit in sharing (establish collective, situated awareness)


Given….

• bundles are everywhere! • access to bundles provides access to

important information• information in bundles is often copied from

other information sources

• we can keep copied/referenced information linked through the use of marks

Current Activities

• developing the architecture for SLIM• extending the bundle/scrap model• testing and optimizing the metamodel &

mappings• beginning a NSF project with US Forest

Service to provide access to forest information • building a tool that might support a medical

task

(CS Team) Plans

“Schema” for bundles: through templates that predefine certain bundles and labels, and possibly predefine scraps. less restrictive than trad. schema.

Sharing: a bundle that belongs to multiple pads, a pad with multiple simultaneous users, and interchange of pads and bundles between users.

“Scoping” of base layers and marks over those layers. There are several general issues for modeling and management of superimposed information that have emerged from this work and other efforts.


(CS Team) Plans (cont.) Distribution: more than a single mark manager. Is there a

single space of marks or must applications keep track of which manager handles a particular mark?

Mark Maintenance:when base layer changes New Kinds of Sources and Marks: beyond XML, PDF, MS

Word, MS Excel, MS PowerPoint and HTML. We are also interested in marks into a “base” layer that is actually superimposed information for another application.

Application Interface: try a more query-like API. Also, consider an API generator

• Superimposed Information Mapping/Conversion: applying and extending our metamodel.

(Captive) Bundles

• SLIMPad - a scratchpad application to create bundles but….with referenced information connected to the underlying source data

• helping us explore architectural issues for building superimposed applications

• motivating definition of a metamodel to represent information with mappings to transform

• inspired by the observational work (but not focused on a specific medical task)
