I am data
History: Telepresence
Tele-presentations
Tele-meetings
Ambience and Presence:
Being there while being here
Dining at home on the “Orient Express”
History: The remote worker rediscovers the PERSONAL
computer

Can we
scan your
books and
put them
online?
Raj Reddy
Sure! Don’t worry
about copyright
stuff. Microsoft
has lots of
lawyers
1999 – Scanning starts in earnest
“we” start to scan,
put content into
folders & files

Now that it’s in Cyberspace
How do you remember the 20,000+ file names?
Or in which of 1500 folders they live?
What’s about a tool for finding stuff?
Jan 2001 CACM

16 GB; +2/yr
A good place to
stop
Began search for
search engines,
especially for email.
Jim suggests that
we build a system
that would be
easier to use and
have many more
capabilities.
2001 Capture goes beyond paper
Gordon, You
should be using
a database.
Jim, I don’t
need no stinkin’
database!
Re-discovery of Memex
As 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
Even more capture

Telephone calls, more video, all web pages
visited, keyboard and mouse usage logging,
radio, TV…
2003 - SenseCam

Epiphany!
Memex is a database

personal TP system

MyLifeBits Software
Everything goes in a database

MyLIfeBits need all the features of a database
(Consistency, Indexing, Pivoting, Queries, Speed/scalability, Backup,
Replication)

If we didn’t use one, we’ll eventually create one!

Cell phone sized device (CPSD) will be the platform!
On Applications… think about CPSD as the platform and context

Search is the “killer app” pretty much as Bush described.

Screen savers “memory refreshers” also provide ambience

Where did my day to?
Users are unwilling to spend time managing their computers or data.

Meta-data, classification, etc. must be automatic

User-input meta-data e.g. Dublin Core – naïve’ Librarian’s dream.

We have nice scheme for classification using facets. It requires work.
Time is the most important meta-data. Photos: place (GPS), subject.
Folders are a good and bad idea.

Most users don’t know what they are or how they work

If used, over time, they become useless: too many, miss-file, etc.
User should put “every” information fragment into the system. e.g., to dos,
call backs, business cards numbers, attention events. It pays.
Same information in multiple places always becomes obsolete.
Capturing Everything:
Phone calls in context of cell phone as a
platform for communication and capture
 Formal Meetings
 Rooms
 Everything in daily life
 Personal health and medical monitoring
 Memex for scientists and engineers

BodyMedia Output
Polysomnogram for sleep apnea.
Real time health monitoring
Microsoft Research SensCam II
Sensors:
VGA camera w/ wide-angle lens
 light level in R,G,B and white
 ambient temperature
 passive infrared for person detection
 accelerometers
 three, programmable buttons, LEDs, sounder
 audio level & audio recording
 USB 2 and SD memory. 1-2 K photos/day
 Not GPS

SenseCam University Grant Program
MSFT supplies money, software, SenseCams

Memex vision: Notebook for engineers & scientists
Medical & health: observations & memory recall,
including diet and exercise
Education: How do people learn?
Help me learn/remember!
Tourist e.g. museum experience
Plumbing


Security
Filtering many images, voice & location annotation
More real time experience capture
Real time medical & health monitoring
 MIT. Deb Roy home capture to understan
how his children learn
 U. of Tokyo. Ubiquitous home
 Columbia U. Voice & sound record & profile
 MIT. iDat. Electronic lab that records
everything into your notebook


Retrieval in a Ubiquitious Home

Going beyond plain old photography and videography




Print, view, and file in scrapbook or shoebox
Digitized bits offers worldwide sharing and easy sharing
Screensaver is useful, but is it a killer app?
The cell phone sized device (CPSD)… one device




Next generation platform
Phones and messaging e.g. sms, mail, web, iM, blogging
Audio, photo, video record and viewing (incl. broadcast)
Within 5 years and with supplemental devices, will take on
the PC
Capture, storage, retrieval, and display
Challenge putting them together

Challenges

Data-types




Quantity expanding i.e. info explosion
New capabilities e.g. real time create new data-types
Meta-data to increase value & provide pivots
Going beyond a PC to a distributed environment





Network environment, including media center
Into the cloud. Especially important for social aspects
Periphery… smart buildings, objects,
Backup, migration, and caching for beyond a Terabyte
Expanding network: PC > LANs > web > p2p(eer)

Schema sharing among disparate systems

CARPE (real time data capture)
 Rooms, phone calls, SenseCam, Health transducers, etc.

Security, privacy, forgetfulness, deniability, etc.
More challenges

Dear Appy: Monitoring and automatic migration of files that
are unlikely to be understood on future platforms as well as
platform migration.
Get What I Need: GWIN…Endless, but evolutionary
improvements in search: misspellings, stemming synonyms
Endless frontier of schema and extensions to them for new
applications e.g. making org charts, family relationships.
CARPE… a whole new game!
Versioning is essential
Scaling.. We don’t know what happens at a Terabyte
What can, should be, or will be in the cloud? Books… videos
Will we be allowed to use such systems? Copyright laws
vary: E.g. ripping CDs, copy of anything, photos,
conversations
The “dear appy” problem
Dear Appy,
How committed are you?
Please come back to me.
Forever yours truly,
Lost and forgotten data

Who’s responsible?
Media or 8 track cassette, 8” floppy
Evolving platform, file, and database
Evolving, incompatible standards & formats for
legacy data that disregard ancestors
Evolving and/or disappearing apps
Is Cyberspace a safe store?
Don’t your physical records
e.g. paper last forever?
What about information on
your CDs, tapes, hard drives,
solid state devices?
Automatic classification problem


XML on bills and imported content… transactions
We need to download classifications rather than
build them




Definitions & synonyms should help find what I want
Today it is too expensive to manually classify
scanned paper. E.g. “right time” meta-data is critical!
We hope “the system” can classify papers and other
documents e.g. bills. Ideally, build Dublin Core
In 10 years we need all documents to appear
electronically & classified with a little help from me
