Notes by Tilke Judd
Review of Visual Social Computing
- Tom Yeh mentions a more advanced CAPTCHA with HotOrNot which asks
for hottest female or male to prove you are human
http://www.hotcaptcha.com/
- We discuss next trends for media: holographic video, virtual
reality, interactive media, hallucination, dreams
Guest notes that past technology in recording and replaying haven't
vastly changed; nothing has been extremely disruptive
3D discussion:
Fredo - 3D stuff has been the future for 30 years and hasn't happened.
Either technology is not mature enough or people don't want it.
Eugene - doesn't like 3D movies, prefers the artistic aspect of 2D.
Fredo - 3D movie Wings of Courage 20 min IMAX 3D director Jean-Jacques
Annaud was a compelling story

Guest - it is easy to predict that photo and video sharing sites will
exist. it is difficult to predict that it will be worth 2.6
billion
dollars [talking in reference to youtube]

Jeff Heer http://jheer.org/
came and gave a talk in Media Lab.
He works in visualization graphics and aims to make large image
databases viewable.
He developed open source gadgets widgits to make visualization
Summary of discussion (see summary)
in addition, other interesting comments were made:
Two people gone missing and image data was used to help find them:
Jim Gray http://www.helpfindjim.com/
Steve Fossett
lost in balloon accident

Robert Plaiss (sp?): Given a webcam, people can tell where it is
located to 50 mile precision based on sun
angle and weather pattern
Webcam with gun; kill deer and it will be sent to you

how to make others feel comfortable with surveillance
- have everyone get access to video
- have video below camera showing what is being recorded
- have a camera-free map of cities
Ramesh: new IDcam from Sony.
If you take a picture of an ad with an
blinking LED beacon, you will get the image and the transmitted URL.

upcoming HW: think of 3 questions you would ask the visitor from Nokia.
HW4: How can we improve mobile photography?
Mobile Computing
Ramesh - Steve Feiner predicted that within 10 years there will be
blimps on major cities so that you can track a person.

Eugene -
brief history of photography:
early large cameras, very static images
compact cameras: more spontaneous images
new digital cameras: color, auto focus and exposure new but no
fundamental difference in the type of images
mobile phones: crap quality, but everyone has one all the time,
so we
can share photos instantly
Why we take photos:
1) Creating and Maintaining Social Relationships
before photo sharing was local and synchronous (like showing a photo
album)
now photo sharing is remote and asynchronous (like flickr)
The rest of the domain remains to be explored
2) Personal memory and Group Memory
with mobile phones, instead of capturing special moments, we now
capture fleeting moments of everyday life
Kodak moment vs Nokia moment
3) Self-Expression and Self Presentation
this area won't change too much due to mobile phones
4) Functional Reasons
taking useful photos (pictures of the label of wine, photo of
whiteboard)
mobile photography will help this area move forward drastically.

Eugene reviewed a couple papers:
Searching the Web with Mobile Images for Location Recognition, Tom
Yeh, Konrad Tollmar, and Trevor Darrell, CVPR 2004.
Richard Sharp (2004) identify ways that mobile phones can be protable
remotes for devices
Markus Kahari and David Murphy from Nokia have
an application which
finds friends and places through the phone (2004)
