Knowledge Building Through Collaborative Hypervideo Creation

How do we learn?
(in general)
How do we learn?
by making connections between resources
- we link two pieces of information through a meaningful connection
- we share / exchange these connections with others
➜ network of associative connections that tells us more about a subject than the sum of it's facts
How can the web help?
Hypertext-Network, based on connections between document fragments (links)
➜ enables us to bring associative connections into a form that is usable for others
How can the web help?
But:
- if we want to share / exchange pieces of that "knowledge-network"
- we can only share a connection from a to b (jumplink)
If that was the way we learn,
learning would mean vocabulary training
How can the web help?
Original Hypertext Ideas
memex (Memory Extender)
"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. It is an enlarged intimate supplement to his memory"
How can the web help?
"Trails" in the memex
- sequence of links through your personal document collection
- can be shared with others, who include it in their own memex & merge it with their trails
➜ We build knowledge by creating, sharing & merging sequences of information!
Sequences of information ➜ Stories
What does this have to do with video?
What does this have to do with video?
➜ Film already works in sequences
Considering the increasing use of video on the web, we should start making use of it in the way we use hypertext!
But:
- linear
- closed source / prerendered
What does this have to do with video?
To be part of a dynamic information architecture, medium has to be open / remixable
What does this have to do with video?
Recent web technology developments:
integrate film in the basic architecture of the web
Before:
- Video only as a Plugin (Flash, etc.)
- not accessable / controllable from the outside
- all you could do is press a play button & use a few other controls (if provided)
What does this have to do with video?
Now:
- include video like any other element
- control video playback by programming code
- react to events at certain points of time

Example 2
What does this have to do with video?
This is great, but:
We are still including timebased content
in a hypertext document
(even Youtube is a textpage including videos)
Steps towards a timebased web
Steps towards a timebased web
From hypertext to hypervideo
- time as the main controlling instance
- other web contents included in timebased content, not vice versa
- linked fragments of moving images that become an navigable network
- (imagine a www, consisting of just film)
Steps towards a timebased web
Openness!
possible through new web technologies
& standards, but
- not just a matter of open technology
- authors have to actively preserve the pre-rendering state, to allow collaboration
Open Hypervideo
"Hypervideo on the web
that works like the web"
Open Hypervideo
- Framework to enable creation, reception and remix of hypervideo contents
- Approach towards hypervideo on the web that does justice to hypertext functionalities
(remixable fragments),
as well as filmic properties
- ➜ collaborative hypervideo creation
Open Hypervideo
- Focus on filmic interface & network, not only annotations
- Document access through non-linear narrative
Open Hypervideo > Use Case
"Knowledge Space -
Elementary Particle Physics"
Goal:
make complex scientific research accessible and comprehensible to a broad public
Open Hypervideo > Use Case
Project:
- 21 video sequences on the subject
- shot partly by professionals, partly by pupils
- annotated with additional materials / documents
➜ merged into one hypervideo project

What's next:
- rework player and editing environment
- player will be rebuilt based on the needs
& knowledge of filmmakers
- editing will take place directly in the hypervideo
What about "collaborative knowledge building"?
What about "collaborative knowledge building"?
Back to the beginning:
"we build knowledge by creating, sharing & merging sequences of information"
What about "collaborative knowledge building"?
But most important:
We have to keep in mind how important that openness of standards and technologies is and do everything we can that it stays that way.
Thanks!
