"As We May Think" (1945)
When data of any sort are placed in storage,
they are filed alphabetically or numerically,
and information is found (when it is) by
tracing it down from subclass to subclass.
It can be in only one place, unless duplicates
are used; one has to have rules as to which
path will locate it, and the rules are cumbers-
ome. Having found one item, moreover, one
has to emerge from the system and re-enter
on a new path. The human mind does not
work that way. It operates by association. ...

"As We May Think" (1945) …
... It affords an immediate step, however, to
associative indexing, the basic idea of which
is a provision whereby any item may be
caused at will to select immediately and
automatically another. This is the essential
feature of the memex. The process of tying
two items together is the important thing. ...

"As We May Think" (1945) …
Bush's article 'As We May Think'
(1945) is often seen as
the "origin" of hypertext
Article introduces the Memex
memory extender
store and access information
follow cross-references in the form
of associative trails between pieces
of information (microfilms)
prototypical hypertext machine
trail blazers are those who find delight in
the task of establishing useful trails

The Mother of All Demos (1968)
Douglas Engelbart and his colleagues
at the Stanford Research Institute
developed the oNLine System (NLS) as
part of the Augment Project
vision about the future of interactive computing
NLS was demonstrated at the Fall
Joint Computer Conference in 1968
showed first practical use of hypertext
computer mouse
remote collaboration (connected computers)
raster-scan video monitors
screen windows

Hypertext (1965)
Ted Nelson coined the term hypertext
Nelson started Project Xanadu in 1960
first hypertext project
non-sequential writing
referencing/embedding parts of a document
in another document (transclusion)
transpointing windows
bidirectional (bivisible) links
version and rights management
XanaduSpace 1.0 was released as part of Project
Xanadu in 2007

Digital Documents as a Paper Simulator?
Most people don't understand the logic of the
concept: "What You See Is What You Get" is based
on printing the document out ("get" means "get
WHEN YOU PRINT IT OUT"). And that means a
metaphysical shift: a document can only consist of
what can be printed! This re-froze the computer
document into a closed rectangular object which
cannot be penetrated by outside markings (curtailing
what you could do with paper). No marginal notes,
no sticky notes, no crossouts, no insertions, no
overlays, no highlighting - PAPER UNDER GLASS.

36. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 36February 12, 2012
Some Tips for the Presentation
Talk to the audience and not to your laptop screen
do not read your talk from paper
Make use of available resources and tools (in addition to
slideware) if appropriate
overhead projector
blackboard
paper handouts
laser pointer/highlighter
...
A quick demo, movie or application screenshot can often
help to clarify an approach
37. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 37February 12, 2012
Some Tips for the Presentation ...
Content
put the presented research paper in the right context (topic)
investigate additional resources
- possibly use additional information (not from the paper) in the introduction
- check the content that is referenced in the paper
do no overload your slides with long sentences
- the audience cannot read overloaded slides and at the same time listen to you
do not just summarise the paper
- selection of important parts might be necessary due to time constraints
use graphical features carefully
- a fancy slide background might reduce the readability
- too many colours and different fonts can be distractive
- no "misuse" of animations or sounds
38. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 38February 12, 2012
Some Tips for the Presentation ...
Content
the slides should support your talk rather than being a script that
you read from the screen
make sure that you do not have too much content for the 30 mins
- rehearsal
if you copy content from the paper (e.g. figures) make sure that
they are readable – otherwise redo them
avoid "empty" slides like the classical "Questions?" slide at the
end of a presentation
- the last slide is likely to be shown during the entire Q&A session and should
therefore be used for your give away message (e.g. some conclusions)
prepare some backup slides which might support you during the
Q&A session
39. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 39February 12, 2012
Some Tips for the Presentation ...
Presentation style
the audience will be more attentive if they see that you are
motivated to give the presentation
think about your body language
Preparation
a good preparation gives you more confidence and freedom
during your presentation
practice, practice, practice, ...
40. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 40February 12, 2012
Some Tips for the Audience
Of course the first and most important thing is that you
listen to the interesting talks and learn some new things
Other things you might observe during the presentation
is the structure of the talk clear?
what about the presenter's presentation style
even if you should not comment about these things, you might
always ask yourself how you might have done things differently or
learn new things from good presentations
Ask questions and give comments after the presentation
