Non-Technical Issues
Technical Issues:• Multimedia expertise needed to enhance quality
Human Issues:• I move a lot, so sound level variable• I tell jokes – and you had to be there!• I repeat myself if people arrive late – sounds
strange on recording
Business Issues:• Who owns copyright?• If I record all my talks, will anyone bother coming
in future?
User Issues:• Do users want this – or is it technology-driven?
See Emmott for example of enhance recording

Discussion
Recordings Of Talks• Would recordings of today's talks be useful for (a)
you and (b) your colleagues who can't attend?• Is the sound sufficient or would you want to
integrate the slides?
Remote Participation• Would you (or your colleagues) find it useful to
participate remotely using (say) Skype?• Is sound sufficient or would you want video?
Issues For Us• Is this too time-consuming to do?• Will workshops lose their impact?• Could we involve remote facilitators?
