Cross-Modality Matching (CMM)

From EuroVR Knowledge Base

Description

Cross-modality matching (CMM) is a variation on magnitude estimation. It is based on the premise that a person can monotonically represent the experiences of one sensory modality through another modality by producing a “subjectively equal” representation using a measure of the second sensory modality, e.g., “make this light as bright as the strength of the presence you experienced in this virtual environment”
