Quantification of spaciousness of interiors considering lighting and visual environment (part 1) : verification of spaciousness evaluation using virtual reality with head mounted display in closed interior spaces

Abstract

VR technology development has lifted restrictions in environmental psychology experiment. To verify the reliability of using VR in experiments in our research: quantification of spaciousness, we examined if there s differences between VR space and real space as a reference stimulus in ME method experiments. Major findings are as follows: 1) General luminance balance could be roughly realized in VR, even though the luminance of light emitting parts exceeded the system s output limit. 2) There were no significant differences in the spaciousness evaluation results, except for few cases where the light source parts affected luminance distribution.
