  1. IAT 800 Process Intensity

  2. Outline • Process Intensity • Binary Trees IAT 800

  3. Process Intensity • Process intensity - term coined by Chris Crawford • Refers to the “crunch per bit” ratio • How much processing does the computer do on the data? • Instantial (Sampled) assets – data displayed by computer • Sound files • Bitmaps • Text • Animations • … IAT 800

  4. Instantial assets: Temptation • When one first learning to program, instantial assets provide immediate reward • For art and humanities students, might feel more “safe” • But, instantial assets • Don’t make use of the unique properties of computational media • Limit possibilities for interaction • Create an authorial bottleneck • Are computationally “opaque” IAT 800

  5. The essence of the medium • The essence of the computer as a representational medium is not • Intervention in the production or display of 3 dimensional forms or visual imagery (tools) • Interaction with a participant/observer (interactivity) • Control of electro-mechanical devices (installation) • Mediation of signals from distant locations (communication) • The essence of the computer as a medium is… Computation, processes of mechanical manipulation to which observers can ascribe meaning IAT 800

  6. Computation = code + rhetoric Uninterpreted computation Physical symbol system Complex causal flows Rhetorical strategies Interpretation Representation Rhetorical machine Code machine Overuse of instantial assets blocks flow between code and rhetoric IAT 800

  7. Instantial assets limit interaction • More degrees of interactive freedom require more complexity of response • As the interactor can do more, the program needs to do more • Responses generated from instantial assets… • Limit response to combinations of assets • Require more assets as the range of response grows • Can be an authorial bottleneck • Instantial design tends to limit interaction or collapse response IAT 800

  8. Computational opacity • The meaning of instantial assets are opaque to code • Example: code that triggers video clips can’t reason about or manipulate the meaning of the clips • This opacity limits the code’s ability to resequence these assets in meaningful and interesting ways • Assets must be designed for sequencibility or… • Assets must be “opened-up” to the code IAT 800

  9. But instantial assets aren’t “bad” • Can tap into rich meaning systems • Complex connotations, emotional flavor… • We don’t know how to procedurally generate rich instantial assets • This can quickly become an AI complete problem • Purely procedural work may be overly abstract • Need to appropriately balance the use of instantial assets and procedurality • Develop strategies for manipulation of instantial assets IAT 800
