Motion Ontology

Die Frage nach dem Sein der Animation

Analyze UI motion through Heidegger's phenomenological framework. Does the animation serve disclosure (revealing meaning) or mere decoration (visual noise)?

Heideggerian Framework

Ontological Modes

Zuhandenheit — Ready-to-hand. Motion recedes into the background, supporting intention without demanding attention.

Vorhandenheit — Present-at-hand. Motion obstructs, forcing awareness of the interface itself.

Disclosure Types

  • state_transition — Loading, expanding, toggling
  • spatial_relationship — Belonging, source/target
  • user_confirmation — Input acknowledged
  • hierarchy_reveal — Primary, secondary, tertiary
  • temporal_sequence — Order of operations
