COMM2591 - HMsEx Major Project Research / Development :: Week 4

CoDesign Study3 - Creative Agency Walking 

Aims:

  • Compare and contrast sonic biofeedback as an effective modality against the absence of sonic stimuli and trial this as an effective entrainment method for precision in body and movement kinematics.
  • Collect quantitative pressure and centre of mass (COM) data during movement routines for analysis.
  • Trial extended gesture driven sonification techniques to interrogate and build upon existing literature.

Early interaction design ideas:

  • Needs to be expressive and immediate (sound felt, not heard)
  • Exponential/logarithmic curvature in MIDI scaling (greater expression)


Literature to read:

Sonification - Stephen Barrass (University of Canberra)

Kirsten Packham (De Quincey Co) is the sole study participant. A trained professional in body and movement work, KP has provided the following information to guide the sound design.

These 'Images' are imaginative qualitative descriptors that assist focus and interoceptive kinesthetic awareness while conducting the respective routine they describe.

I have used these to make early sound design notes which will be put into practice later.


1. MOVE LIKE YOU DON'T WANT TO DISTURB THE AIR 

Very slow. All the molecules in the room are affected by your movement. 
  • (bass rumble + high end - high and lowpass filters :: mids notched out )
  • chimes

Colluding with the air. 
  • reverb on top end? ie: room size, decay 

Feet lift slightly, glide across floor and negotiate with the air. 
  • Filter (opening? / closing? - small range)

Minimal articulation and gait. 
  • articulation spikes to be sonified? possible distraction here

Weight held in core. 
  • central bass tone at centre of gravity 

Legato. 
  • pitch bend
  • max 1 semitone on bass *if at all*
  • maybe 2+ semitones on high tone



2. PUPPET 

Slow. 
  • Fine control
  • Rhythmic
Articulate loose feet. 
  • Wide control mapping??
  • Rhythmic articulation, tight envelopes
  • Each note discrete playing in a “circus” scale
Awkward. 
  • Wide range
Sense of up/down, lifting and lowering. 
  • Filter
  • Pitch
  • Wide control range
  • Bells, FM
    Backing track?
Variation in each iteration/step.

  • cycling MIDI notes through scale?
  • pitch modulation?


3. GLACIER CALVING 

Slow-very slow. 
  • Drone

Feet - ball/heel/toes sink as if crumbling and breaking off into floor - being absorbed by floor. 
  • Filter closing with each step
  • Delay/Reverb
  • Noise/Pitched down Ice crunchy sound on top through filter

Scale is massive. 
  • Bass

Energy down.

  • Bass


4. OMNIPRESENT - ALL SEEING BEING 

Slow. 


Purposeful, forward direction but sensing/360 Omni central awareness. 
  • Panning 
  • Constant tone, amp + possibly filtering independent stereo channels drops and raises to indicate unbalanced gait
  • Mid High frequencies
  • Chords (synth tbd - basic fm)

Weight held in core. 
  • Pan triggered from Centre of Mass
  • Perhaps all triggers from COM

Whole body glides. Gait even.
  • Sound cues to entrain central movement



5. GULLIVER'S TRAVELS 

Slow. 

Incrementally lifted and lowered. 

Weight lifted up by many hands, carried and carefully lowered. 
  • Up fast, lowered slow
  • Pitch going up matched to pressure
  • Pitch alone?
  • Distinct Clear tonal change between up and down env

Articulate feet.



7. DEER PREY 

Slow with variation and stops.
  • Rhythmic? ala ‘Puppet'
  • Use sound cues to reinforce stops

Light feet listening, sensing vibrations. 
  • Pressure too heavy or uneven gait - wobble filter?

Articulate. 
  • Precise mapping

Weight held in core.
  • Centre of Mass

Also - Music references

Machinefabriek - Singel
Oren Ambarchi - Song of Separation part 2
Alva Noto - J
Christina Kubsich - In Transition
Triosk - Lazyboat

(^ Great music selection! However I don't think I will be using these as timbral inspiration after all - familiarity may bias the data)


Finally from Frank:

"Finally - i've been finding this paper by Varni et al 2012 attached quite cool as it uses a MOOG cutoff filter to respond to ideas of energy. Have a look and we can discuss tomorrow.  btw i have a MOOG minitaur !!"

(Think i'll keep hardware out of this in the aim of simplicity - dynamic parameter mapping using some digital, some outboard will be a mess)
