  1. Cognition of spatial separationin the interior Comparative experiments using computer graphics and full-scale model Naoyuki Oi (Faculty of Design, Kyushu Univ.)

  2. Introduction • Four spatial concepts for connected space 1) Inui et al.: concept of SPACIOUSNESS for rooms with a window 2) Subjective UNIT of space 3) CONTINUITY of two spaces 4) SPATIAL SEPARATION

  3. Spaciousness, UnitContinuity and Separation

  4. Simulation techniques • Full-scale models • Computer graphics (Still images) • Easy to prepare many settings but depth perception etc. could be different • The same settings as full-scale models are used for the comparative study

  5. Simulation techniques

  6. Simulated space

  7. Objectives • Explore separation concept in the room • Compare full-scale models and CGs

  8. Three experiments • Experiment 1: Computer Graphics. Each subject estimates the projected images on the screen from the specified seating position. • Experiment 2: Full-scale Models. Each subject estimates the real space of full-scale models from the specified seating position. • Experiment 3: Full-scale Models. Each subject estimates the real space of full-scale models while walking along the instructed route in the space.

  9. Methods • Magnitude Estimation method for spatial separation • Seven rank grading for the impression on • “easy (or hard) to go through” • “easy (or hard) to find the situation of the other side” • “two spaces look similar (or not)” • Subjects: 20 students (10 female, 10 male)

  10. Results • The similar tendency among subjects is found, that is spatial separation is a common feeling. • Short walls from both sides create less separation than the other type of walls. • Experiment 3 shows similar results, except the impression of the easiness of movement for 1110mm low partition.

  11. Results • Height of partition wall and separation

  12. Results • Wall type and separation

  13. Conclusion • The spatial separation concept has large possibility in the room design • Still images of Computer Graphics for the cognition of spatial separation is valid so far • The further work should be needed, as the eye point for CG experiment has some influence
