Abstract

With olfactory-visual coupling intervention as an example, the work aims to investigate whether cross-modal matching can promote anxiety relief, with a hope to enhance emotion regulation efficacy. Human factors assessment methods such as EEG, HRV-LF/HF and STAI scales were combined to conduct an incremental study. Firstly, the anxiolytic effects of bergamot, sandalwood and jasmine were verified. Secondly, the olfactory-visual combination based on emotional-perceptual matching and cognitive-recognition matching was constructed through the coupling matching experiment. Finally, olfactory-visual coupling intervention experiments were conducted to investigate the effects of different cross-modal matching relationships on emotional stress relief efficacy. The cross-modal matched olfactory-visual element coupling intervention enhanced the relaxation efficacy of anxiolytic odours and there was no significant difference between the two matching mechanisms. The work reveals that in order to ensure the efficacy of emotion regulation, the design of emotion regulation with multisensory interventions should pay attention to cross-modal matching, and the matching mechanism can be flexibly selected according to the actual situation in the design practice.

Key words
