Video Based Mobile Learning
H. L. Cycon, A. C. Wagner, F.Topfstedt, H.Regensburg
The problem is old
There were always
new proposed solutions
In Nurenberg about 1647 somebody had a good
idea…
Since then there are popping up always new variations of this:
The Nurenberg Funnel Myth:
There is a fast and convenient way
to get knowledge into the students
List of “New” Technologies
• Radio lectures
• Television /Video teaching • Computer based learning
• e Learning, distance learning • m Learning? (video based?)
technology is not pedagogics !
Outline
• Introduction • m Learning
• Limitations/Problems/Potential • What did we do: Nibbler
• Next steps • Conclusions
m Learning
Why mobile?
• (almost) everybody has a mobile • PDAs go multimedia & networking
• Mobile phones go computing & organizing converging into smart phones
• IP services go wireless, ubiquitously
Why Video?
• Visual/audio perceptions are the “broadband” channels to our mind
• High A/V quality (at lowest possible technical level) increases acceptance of content
What can we do with videos?
• Lecture ("talking head") • Demonstration
• Animation
• Illustrate / exemplify • Actors as teachers • Soap opera
• Game based learning (video quizzes,..) • Video podcasts
m Learning
Limitations
Limited .. - screen size - battery life - processing power - memory - bandwidth• HW & Connection costs to high
m Learning
Problems I
• content tailoring needed • Short attention span
– Adapted learning objects – Micro learning
m Learning
Potential
• Everywhere & always readily accessible
– Spare time “playing” device, use it!
(People spend hours in trains, buses.. daily)
• Recall/repetitions of lectures • Preparations for exams
• Knowledge in your pocket
• Pick up the kids from where they are • Lifelong learning
• On the job training "just in time" to solve a problem or gain an update
What did we do
• several groups do video recording of lectures & use streaming of content (Barthel, Sieck, Cycon,…)
• iTunes, MS media streaming
Podcast via iTunes

e/mLearning content processing & managing (Th. Schmidt et.al.)
• multitude of different devices restrains device independent delivery
m Learning
Problems II
Generic Content Transformation
Generic Content Transformation
(
Nibbler (our approach)
• Semi automatic AV multi-format converter/distributor
• web based, ubiquitous • Cross platform solution • No system restrictions
Nibbler (handling)
• straight simple linear workflow • user centred, media based
• rapid allocation, rapid prototyping
• covers formats & devices within one flow • streaming from mobile to LAN
Technicalities Nibbler
• Accepts upload of audio/video content in almost “any” format
• Converts (transcodes) content into
platform independent streaming format (e.g.Flash)…and
• “all” other mobile formats
Technicalities Nibbler
• Produces media formats for mobile devices i.e.
– in SQCIF and QCIF resolutions (based on H.263 inside a 3GP container)
– Apple's iPod and Sony's Play Station Portable (PSP) ,different MPEG4 containers.
– Nokia's Internet Tablets 700 and N800 based on Xvid video- and MP3 audio compression inside an AVI-Container.
– Audio only (MP3 or AAC ) in different qualities
• streaming in different Qualities (Flash): modem to LAN (8MB/s HDV H264 encoded; in preparation)
Nibbler (add on)
• Flash Video Player Component allows seeking for progressive downloads ("Streaming
experience")
• FLV Scrubber 3: Flash 9+, introduced
H.264/AAC support (Flash Player 9 Update +) • FLV Scrubber 2: Flash 7+, running even on
some mobiles and game consoles
• Free for non-commercial-, cheap for commercial usage
Results/ experiences
• Recording of math lectures with HDV camera (no editing rapid allocation)
• Producing with camtasia /davico
• Available as stationary streaming & mobile download
good resonances by students (no systematic survey)
m Learning
next steps
• mobile multimedia streaming (UMTS…) • mobile multimedia real-time
communications (video conferencing) • mobile multimedia group conferencing
m Learning
next steps
• BMBF Project Moviecast
– Codec development (H264/ SVC) for mobiles – mobile group video communication
– mobile multicast
(Th.Schmidt, H.Hamburg)
• Game Based eVideo Project (in preparation)
Demos
• „Lectures to go“ on mobile
phones ,PDAs, PSPs, iPods, HDV
• m Learning has a rising potential (filling time gaps, good for “repetitions” & exam
preparations)
• still mostly textual but video based versions rise
• technical limitations will be overcome • Mobile Multimedia Group Conferencing
scenarios need consideration (mobile

Again:
The nurenberg funnel has not been found But….
