  1. Passive Capture & Ensuing Issue for a Personal Lifetime Store Jim Gemmell, Lyndsay Williams, Ken Wood, Roger Lueder & Gordon BellCARPE Workshop Oct 15, 2004

  2. The Price of Active Capture “When I had my first child, I bought a camera and took many pictures. But eventually I realized I was living behind the camera and no longer taking part in special events. I gave that up – now I don’t have nearly as many pictures of my second child.”

  3. Passive Capture • Make capture passive • Let the user experience! • Save a rich record of personal experience • Possible application as memory aid • The challenge: we were already swamped in media… won’t this just make it worse?

  4. Outline • What is SenseCam • What is MyLifeBits • Demo • Conclusion

  5. SenseCam

  6. sensecama photographic memory for everyone Ken Wood & Lyndsay Williams Microsoft Research Cambridge 15 Oct 2004

  7. sensecam • Essentially a “Black Box” data and image recorder for the human body • Current wearable prototype can be worn for a day and captures up to 2000 images in 12 hours • Image capture triggered by sensors, e.g. motion, light, temperature, people in field of view, ... • Sensor data is also recorded for later presentation, analysis, and correlation

  8. a short walk through Cambridge

  9. image stabilisation • Accelerometer measures motion of the device • When any sensor indicates image capture, we wait a few tens of milliseconds to capture image when movement is less than 10 degrees/second if possible • Greatly reduces the number of blurred images Before After

  10. ultra wide-angle lens • Captures everything regardless of exact camera orientation

  11. dealing with sensecam data: MyLifeBits Sensor readings Corresponding images in rapid serial viewer

  12. status and plans • 12 devices built; adding audio trigger and GPS • But hardware is just the beginning • Trials and studies are the interesting bit • domestic probe • give it to people and see what they do: personal memory enhancement? family fun? • clinical trials with memory-loss patients • ethics approval for 20 Cambridge patients over 3 years • tourism trials • Edinburgh Festival, museums, ... • cross-cultural privacy study • UK, China, India, Egypt, ...

  14. MyLifeBits

  15. MyLifeBits is: • An experiment in lifetime storage • Digitizing Gordon Bell’s past • Capturing more of his future • A software system • Capture • Storage & retrieval • Organization & annotation • Minimum requirement: fulfill Vannevar Bush’s 1945 “Memex” vision

  16. The guinea pig • Has now scanned virtually all: • Books written (and read when possible) • Personal documents (correspondence including memos and email, bills, legal documents, papers written, …) • Photos • Posters, paintings, photo of things (artifacts, …medals, plaques) • Home movies and videos • CD collection • And, of course, all PC files • Now recording: phone, radio, TV (movies), web pages… conversations and meetings to come • Paperless throughout 2002. 12” scanned, 12’ discarded. • Only 44 GB, incl. 10 wma, 14 SQL!!! Video: o(100) + 500 mov

  17. So you’ve got it – now what do you do with it? “A record if it is to be useful … must be continuously extended, it must be stored, and above all it must be consulted” “The difficulty seems to be, not so much that we publish unduly … but rather that publication has been extended far beyond our present ability to make real use of the record” - Vannevar Bush

  18. Everything goes in a database • You need all the features of a database(Consistency, Indexing, Pivoting, Queries, Speed/scalability, Backup, replication) • If you don’t use one, you will find yourself creating one! • Files as blobs, also sync with file system for legacy apps SQL

  21. DEMO

  22. A Storocratic Oath • Do no harm to dates(File creation, Photo taken) • Do no harm to device created & other meta-data. • Camera data & location data are sacred. • Support & aid the creation of critical meta-data. • When/how the user feels like it • Auto-magically! • Maintain user confidentiality

  25. Collaborators • Other MSR Collaborators: Kentaro Toyama, Ron Logan, Steve Drucker, Curtis Wong, Mary Czerwinski, Brian Meyers • Interns: Josh Blumenstock, Evan Salomon, Aleks Aris

  26. MemexAs We May Think, Vannevar Bush, 1945 “A memex is a device in which an individual stores all his books, records, and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility” • Full-text search, text & audio annotations, and hyperlinks

  27. The AI Challenge:Content analysis & Data Mining “Creative thought and essentially repetitive thought are very different things. For the latter there are, and may be, powerful mechanical aids” – Vannevar Bush • Is MyLifeBits just enough rope to hang yourself with? • MyLifeBits must become MyPersonalAssistant • Content analysis and data mining • Doc similarity & “clean living” • Document meta-data extraction

  28. Moving forward:new capture modes/devices Deja View Body Media SenseCam Quindi

  29. Future work: UI • Focus to date on functionality – now we need to make it friendlier • User studies with SFSU

  30. Web Scout Future work: Visualizations Don't give me a little card image and say, "That's all you've got, because that's what I thought you should want for your virtual shoebox." There have got to be multiple modalities and the designers have to be able to deal with that. … don't metaphor me in, don't give me only one way of looking at things. -Andy van Dam, Hypertext '87 Keynote Address U. Maryland IN-SPIRE Next Media

  31. By Gordon Bellhttp://research.microsoft.com/~gbell Dear Appy, How committed are you? Signed, Lost and Forgotten Data Dear Appy, I'm having trouble with long-term commitment -- not on my end, heaven knows, but from the apps that created me and with whom I like to associate. Over time, these pesky apps evolve and they simply don't recognize the data that they once helped create! But, we data progeny -- and there are lots of us -- feel that as our creators, these apps should be responsible for eternal support. But the little problem with recognition isn't the worst of it – sometimes the apps even disappear altogether. I ask you, is it expecting too much for 20-something year old data like me to be interpretable by my app (e.g. Acrobat, DB2, Draw, Eudora, Office, Quicken, or RealNetworks), or am I just associating with irresponsible apps? If things continue on their current path, it seems I will be completely un-interpretable within 20 to 50 years! My apps will move to other platforms, or evolve to be more Internet- or Next-Big-Thing-centric...

  32. Classification wish list • Download classifications rather than build them • Definitions & synonyms should help find what I want • Today it is too expensive to manually classify my scanned paper. E.g. “right time” meta-data is critical! • Next year I hope “the system” can classify papers and other documents e.g. bills • In 10 years I expect all documents to appear electronically & classified with a little help from me

  33. Personal Search is notProfessional or Web search • System sees every entry & access • Everything, not just a professional life • Limited to SIS, not an infinite amount, covers a profession & personal life Professional user Depth e.g. information item types & coverage MyLifeBits Web as seen by search engines Knowledge breadth e.g. Dewey classification
