TravARlog brings nostalgia for the koukan-nikki to modern technology by pairing an iOS app with an postcards. Through mixed reality, the app helps creators build and preserve memories in a virtual environment. Meanwhile, the recipient receives a tangible 'Key' in the form of a unique physical postcard that unlocks the sender's thoughtfully curated augmented reality.

• What is “Koukan-nikki” ?
"Koukan-nikki" translates to "Exchange Diary" in English. Exchange diaries were a popular trend in the 1990s, where people shared a notebook, taking turns to write their thoughts, comments, and experiences. This practice fostered a deep sense of connection—one that feels increasingly rare in today’s digital age.

• Wendy’s Exchange Diary Practice:
Today, I am dissatisfied with contemporary social media because the gap between technology and tangible experiences continues to widen. We need digital spaces that foster deep reflection, authentic self-expression, and meaningful interactions that bridge technology and human experience.
• What’s special about the “Key”?

I want to recreate the feeling of losing my notebook key in 2006—a small moment that carried deep nostalgia, symbolizing the fragility of memories
