  1. The “Lifestream” Approach to Reorganizing the Information World By Nicholas Carriero, Scott Feritag, Eric Freeman and David Gelernter

  2. What is Lifestreams • Uses a simple organizational metaphor, a time-ordered stream of documents, to replace conventional files and directories • Subsumes many separate desktop applications to accomplish the most common communication, scheduling, search and retrieval tasks

  3. Lifestreams Interface

  4. Why is Lifestreams • Users of common desktop systems have difficulty in • Organizing and finding information within hierarchical file systems • Making use of archived information • Getting a “big picture” view • Managing schedules and reminders • Lifestreams organizes the electronic documents in a fluid and natural way

  5. How Lifestreams works • Five primary operations • New creates a empty document • Clone duplicates an existing document • Transfer copies a document from your stream to someone else’s • Find prompts the user for a search query and creates a substream • Summary allows users to distill the information in a large number of similar documents into a single overview

  6. How Lifestreams works (cont.) • Past, present and future • Dialing the clock into the past allows users to explore past regions of the stream • Dialing the clock into the future allows users to create a reminder notice • Agents • Used to extend the functionality of Lifestreams

  7. Lifestreams Goals • “Names” and “directories” should be junked as organizing devices for infochunks • The system should provide logic for finding a chunk or group of chunks • The system should provide logic for summarizing or compressing a large group of related chunks • “Compatibility” should be automatic • Explicit file-storage management should be junked.

  8. Current Status • Servers run on Unix workstation • The chunks in a Lifestream are represented using a machine-independent external data representation (XDR) • X-Window Motif user interface

  9. Conclusion • HCI Metrics • User Performance • Error Rate • User satisfaction • Learning time • Retention • Supports the management of electronic objects efficiently and transparently • Organizes the electronic objects in the way that reflects the way users work
