How to Categorize/Analyze Existing Controllers?

Contents

Dichotomies

  • Sonification vs. Deliberate Control
  • Individual vs. Group
    • Sid Fels -- Tooka
    • Jorda -- Reactable
    • David Merrill, Tim Hankins, Jocelyn Robert -- COOL (120M)
    • Rodrigo Segnini, Hiroko Terasawa, Vivian Woo -- Sound Kitchen (42M)


Dimension Space Analysis

  • Arbitrary number of axes, not necessarily orthogonal
  • Axes may be continuous, discrete & ordered, or eccentric & unordered
  • Arrange axes in radial symmetry, each analysis creates a unique 2-D shape


Rasmussen's Human-Machine Interaction

  • Skill-based
    • "Real-time continuous response to a continuous signal."
    • Controlling a signal
    • High control rate
    • E.g. Instrumental performance
    • David Birnbaum's Rulers
  • Rule-based
    • "Selection and execution of stored procedures in response to cues extracted from the system"
    • Controlling a process
    • E.g. a Sequencer, like Grid Drum (above)
  • Knowledge/Model-based
    • "directed toward a conceptual goal. Active reasoning must be used before an appropriate action (rule- or skill-based) is taken."
    • Not characterized by literal presentation, but concept behind it.
    • Active interpretation by performer.
    • E.g. Live coding -- ChucK
    • Mark Hauenstein's Audio Shaker


Blaine & Fels' Contexts of Collaborative Musical Experiences

  • Balancing complexity and expressivity
    • But can't something be complex and expressive, if the performer is skilled??
  • Focus
    • Player to Player
    • Players to Audience
  • Location
    • Local vs. Remote
  • Media
    • Audio/Visual/Mixed
    • A/V causality
  • Scalability
  • Player Interaction
    • Specific roles
    • N copies
    • Jamming
    • Interdependency
  • Musical Range
    • Constraint
  • Physical Interface
  • Directed Interaction
    • Leader-follower
    • Turn-taking
    • Call-and-response
    • Expert leader
  • Pathway to Expert Performance
    • Compromised when ease of learning is achieved by constraining musical material
  • Level of Physicality


Themes

  • Scenario
    • Who, where, when?
    • Performance? installation? toy?
    • Local/Remote
  • Skill
    • Expert? anyone?
    • Threshold -- entry fee
    • Ceiling -- ability to develop virtuosity
    • Assumed prior knowledge/ability
  • Style
    • Ceiling
    • Walls -- range of actions, results
    • Paths from A-> B, is variation in gesture predictably reflected in sound
      • Controllability, mapping
    • Virtuosity, expression
  • Scale
    • Dynamic range
    • Range of sounds
    • Range of gestures
    • Degrees of freedom
