 +===== 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?
