For the preliminary research on scent, the team members looked up literature, did online questionnaires to collect data, and conducted offline interviews with passers-by of different age groups. Based on this, we summarised people’s impressions of odors in different age groups and selected the most representative 2-3 odors for each life stage.
After identifying the representative scents for the different age groups, we started to purchase essential oils and perfumes. We went to essential oil shops and soap shops to experience the different scents for ourselves and to buy the ones we needed. At the same time, we also purchased some of the specified scents online. After receiving all the scents, we formulated a scent for each age group based on our previous research and recorded the ratios.
In the end, we formulated the scents for each of the five scenes, melted them in water, and used an aromatherapy machine to enable the scents to be dispersed.
