1 Video Based Mobile Learning H. L. Cycon, A. C. Wagner, F.Topfstedt, H.Regensburg FHTW Berlin, University of Applied Sciences Cycon,Wagner,et.al.,FHTW 1

2 Prolog Cycon,Wagner,et.al.,FHTW 2

3 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: Quelle: Wikipedia Cycon,Wagner,et.al.,FHTW 3

4 The Nurenberg Funnel Myth: There is a fast and convenient way to get knowledge into the students head Cycon,Wagner,et.al.,FHTW 4

5 List of New Technologies Radio lectures Television /Video teaching Computer based learning e Learning, distance learning m Learning? (video based?) technology is not pedagogics! can we use it? Cycon,Wagner,et.al.,FHTW 5

6 Outline Introduction m Learning Limitations/Problems/Potential What did we do: Nibbler Next steps Conclusions Cycon,Wagner,et.al.,FHTW 6

7 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 Mobile competence is high (& growing) Cycon,Wagner,et.al.,FHTW 7

8 Mobile devices owned Quelle:Corbeil & Corbeil U Brownsville Texas Cycon,Wagner,et.al.,FHTW 8

9 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 Best substitute for life experience Cycon,Wagner,et.al.,FHTW 9

10 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 Cycon,Wagner,et.al.,FHTW 10

11 Limited.. - screen size - battery life - processing power - memory - bandwidth m Learning Limitations HW & Connection costs to high to be solved in 3-4 HW generations Cycon,Wagner,et.al.,FHTW 11

12 m Learning Problems I content tailoring needed Short attention span Adapted learning objects Micro learning Cycon,Wagner,et.al.,FHTW 12

13 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 Cycon,Wagner,et.al.,FHTW 13

14 What did we do several groups do video recording of lectures & use streaming of content (Barthel, Sieck, Cycon, ) itunes, MS media streaming Students use off-line mobile players Cycon,Wagner,et.al.,FHTW 14

15 Podcast via itunes (K.U.Barthel) Cycon,Wagner,et.al.,FHTW 15

16 hylos e/mlearning content processing & managing (Th. Schmidt et.al.) Thank You Quelle: Hylos Cycon,Wagner,et.al.,FHTW 16

17 m Learning Problems II multitude of different devices restrains device independent delivery Cycon,Wagner,et.al.,FHTW 17

18 Generic Content Transformation (Sieck,, Herzog, et.al.).) Cycon,Wagner,et.al.,FHTW 18

19 Nibbler (our approach) Semi automatic AV multi-format converter/distributor web based, ubiquitous Cross platform solution No system restrictions Cycon,Wagner,et.al.,FHTW 19

20 Nibbler scheme Cycon,Wagner,et.al.,FHTW 20

21 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 HDV streaming is in preparation Cycon,Wagner,et.al.,FHTW 21

22 Upload Cycon,Wagner,et.al.,FHTW 22

23 Streaming & Webcasting Cycon,Wagner,et.al.,FHTW 23

24 Lectures to go offline on mobiles Cycon,Wagner,et.al.,FHTW 24

25 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 Produces RSS-feed / web feed Cycon,Wagner,et.al.,FHTW 25

26 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) Based on ffmpeg -> Processing based on open source Cycon,Wagner,et.al.,FHTW 26

27 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 Cycon,Wagner,et.al.,FHTW 27

28 elearning scheme Cycon,Wagner,et.al.,FHTW 28

29 elearning scheme (soon) Cycon,Wagner,et.al.,FHTW 29

30 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) Cycon,Wagner,et.al.,FHTW 30

31 m Learning next steps mobile multimedia streaming (UMTS ) mobile multimedia real-time communications (video conferencing) mobile multimedia group conferencing Cycon,Wagner,et.al.,FHTW 31

32 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) Cycon,Wagner,et.al.,FHTW 32

33 Demos Lectures to go on mobile phones,pdas, PSPs, ipods, HDV see exibition on Friday Cycon,Wagner,et.al.,FHTW 33

34 Conclusions/Outlook 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 Multicast) Cycon,Wagner,et.al.,FHTW 34
