Lab tests 2012-05-11
Init test (without Torleif)
- Case I (27ms + 27ms):
- conduct-clap + conduct-sing (ta-ta-ta father jacob)
- Vivianne: more behind than last trail (which was 27 + 0ms)
- Leif Arne: No change noticed
- Case II (48 + 27, aspect and resolution change in video viewed by conductor)
- conduct-clap + conduct-sing (ta-ta-ta father jacob)
- Vivianne: not much difference
- leif arne & daniel: Less syncronized, more difficult two follow during slow-down
- Case III (48 +48, aspect+resolution change both directions):
- conduct-clap
- clap (no conduct)
- echo (reverberation) noticable and disturbing
- clap (no conduct, one-way audio)
- conduct-sing (ta-ta-ta father jacob, one-way audio)
- ?
- Case V (48 + 70)
- Better image, one way audio
- conduct-clap
- clap-clap
- vivanne can hear delay
- conduct-sing (ta-ta-ta father jacob, one-way audio)
- clap-clap with two-way audio
Tests with Torleif, Vivanne, Daniel, Leif Arne
- Case 0 (in same room)
- conduct-clap
- conduct-sing (ta-ta)
- clap-clap
- vivianne: conduct-clap less presise than clap-clap
- Case I (27+27)
- conduct-clap
- conduct-sing (ta-ta)
- clap-clap
- Thorleif: conductor is smaller, feels more distant
- Vivianne: no noticable delay (compared to in-rom)
- Leif Arne: camera infront no longer an issue (compare to previous test day)
- Case III (48+48)
- conduct-clap
- camear adjustment needed (due to aspect ratio bug)
- conduct-sing (ta-ta)
- clap-clap
- Vivianne: conducting works fine, clapping has delay, on speedup your are behind, on slowdown your are in sync
- Case V (48 + 70)
- conduct-clap
- 30 fps: All noticed, smudged movements
- Retail with 60 fps
- conduct-sing (ta-ta)
- clap-clap
- Vivianne:
- bigger camera make poorer contact with middle person
- delay is managable, simpilar to what is common with large choir (large choir may even be worse)
- Case “Screen size”
- Recorded conductor
- Vivianne: When conductor is approx real size he seems too close
- Combination of too close and recorded conductor is unatural
- Torleif: No problem with enlarged sizes
- Leif Arne: Keystone problems
- Vivanne: 75% of real height seems to be a minimum, smaller give you a “look-for-him” feeling
- Torleif: Size is easy to get used to, close to real size is preferrable though
- Vivianne: Conductors gaze not in camera (but moving around in virtual choir) makes a more distant feeling.
- Case VI (with gstreamer video in one pipeline)
- To be tested next time
- Case VII (with gstreamer video in both the pipe-line)
- delay: ~100ms to ~220ms (unknown distribution/shape of variation)
- conduct-clap
- conduct-sing (ta-ta)
- clap-clap
- conduct-sing (ta-ta)
- Video quality is poorer, video smeard out
- Torleif: Worse than Case V
- Vivianne: Not good. Hard to clap, delay seems much longer than case V. Variance in delay not really noticable.
- Case VIII ( choir sees 3D view of conductor )
- Not to be tested yet due to challenges with technical equipment.
New tests with choir of 8
- Mai 25, preparations from 9:00, choir show 13:00
