CoIP : Labtests 2012-04-27
- Setup
- Lab (Caruso)
- Back projection screen
- Projector design's projector
- 2 mic
- Toshiba camera
- Leif Arne's Office
- Same as Caruso
- Single mic
- Link beetween
- analog audio two ways
- DVI-opticat-DVI one way
- DVI-TP-DVI one way
- Tests
- Conduct and clap - Test 1
- Over link
- 1 to 1: Good experience
- Vivianne: Need to speak slower/clearer than when in same room
- Torleif: On scale for 1-10: 9 ish. Camera infront of screen is disturbing (somewhat)
- Sound sync test (clap + visual): no noticable delay
- 1 to 3: …
- Same room
- 1 to 3 - conduct clap
- Leif arne: Better on link due to reference line at bottom of screen
- Torleif: Focused more on hands on link, most on face when in same room
- Leif arne: Small movements easiers in same room
- Vivianne: More aware of choir's behaviour when in same room
- 1 to 3 - clap-clap:
- Vivianne: linear speedup easier then linear slowdown, more aware
- Leif arne:
- Conduct and clap - Test 2
- Over link
- 1 -3 - conduct-clap
- Vivianne: Feels more distant
- 1 - 3 - clap-clap
- 1 - 3 - conduct-clap no sound
- 1 - 3 - clap-clap no sound
- Vivianne: Feels closer then with sound
- Conduct differently when no sound (says other conductors too)
- same rom
- 1 - 3 - clap-clap eyes closed
- choir synced but lagging (Leif arne: no prediction possible)
- Vivianne: stereo sound and video enables differentiating behavior of choir members
- Hypoteses: Disscrapancies adds up, i.e. video link + audio link is worse than just video or just audio
- Conduct and sing (ta-ta of Father Jakob)
- same room 1 - 3
- over link
- Difference is close to non-noticable, group is getting used to both settings
- Vivianne: More difficult than clapping (due to less percurrsivness)
- Seem to be a fast learning curve for all
- Vivianne is used to adapting (professional) ..?
- same room 1-3 Leif Arne conduction
- Some imprecission
- over link
- Leif Arne did equally well (non-professional) i.e. same room/over link does not effect performance
- Choppy/jumpy effects (i.e. due to low frame-rate) are probably difficult to compansate by conductor
- Need new test-workshop when delay can be introduced (with only Torleif from choir)
- Video and audio delayed differently is of interest
- Test different screen-sizes
- Reduce video quality if possible
- Conclusion: On link quality seems good enough
- Faster frame rate could still make a difference
- watching recorded conductor (woman):
- Leif Arne saw/was disturbed by low frame rate
- Vivianne and Torlaif didn't notice
- watching recorded conductor (man):
- He was moving his eyes (imagening looking at choir members)
- Has that significance for choir?
