In 2019, we see colours across the full spectrum on 4K HD screens or VR headsets. We stream our favourite music and podcasts in lossless audio, transmitted via Bluetooth to our noise-cancelling headphones. We use fingerprints to unlock our smartphones, apply varying pressure to perform different functions. Even the way we taste has experienced its very own behind-the-scenes revolution: we order our takeaways via Deliveroo, our ready meals are prepared and packed by robots and cruelty-free burger patties grown in vitro are now available at your local supermarket.
Described by Wired as “the iTunes of smells”, oNotes allows the user to make playlists of preferred fragrances, overriding our instinct to acclimatise to a new scent after just a few minutes, a phenomenon nicknamed olfactory fatigue. These playlists can be set up to energise us in the morning – peppermint, citrus, coffee – or soothe us in the evening – lavender, chamomile, jasmine – and the benefits have been proven by scientific research as significant.
