We shouldn’t focus too much on brain activity or data recollection. Instead, the experience should centre on real-time sensory input—what we see, hear, smell, or feel. For example, tracking the smell when entering the tube, or noticing how one's body moves in sync with others, can enhance the moment. Tech should be a guide to deeper reflection, not a crutch.

The goal was to make users more aware of their surroundings and themselves, rather than relying on the app to remember it all for them.

As designers here, I couldn't help but think about how every day, even a tube journey can be poetic. There's something powerful about romanticizing everyday moments—like catching a warm glance or hearing laughter on a dirty, loud tube. We might use a physical ticket or object to trigger these memories more deeply than a digital tool could. Since the tube often lacks Wi-Fi, we needed to design in ways that don’t depend on the internet. We asked how someone might mentally revisit a moment later—the sounds, the movement, the feeling. Our role was to enhance that sensory memory, not take over.

Finally, a lot of our points were hypotheses, so we needed to test them.
