IntroductionIntroduction
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

Full-scale modelsComputer 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

ObjectivesObjectives
Explore separation concept in the roomCompare full-scale models and CGs
Three experimentsThree 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.
MethodsMethods
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)
ResultsResults
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.
ResultsResults
Height of partition wall and separation
ResultsResults
Wall type and separation
ConclusionConclusion
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
