I-Link
Letters that connect the screen and the world.
I-Link grew from a desire to help children with ITP stay connected when opportunities for in-person play and friendship are limited. As an individual project, it brings physical letter exchange together with an app prototype and interactive installation. Activities with ITP Home, collectible cards, an acrylic tree, AR, and educational mini-games create different ways to exchange messages, learn, and explore.

A letter travels beyond the screen.
Children write or reply to a letter, upload it, and turn it into a digital card. Parent-assisted delivery and collection connect the physical exchange to the app; a reply starts the next cycle.
Colorful Pen-Pal Connection: ITP Patients Exchange
- Child patients share how they feel about ITP.
- They write or draw their thoughts or questions and leave their contact information.
- We collect, match, and distribute the letters.
- Kids reply to each other, building friendship with peers who share the same experience.

The complete digital experience.
The post box and scanning screens let children send photographed letters, while received cards stay in a personal mailbox. Educational quizzes, badges, and profile screens extend the exchange into learning and collecting.
Messages become objects.
Illustrated correspondence cards sit alongside a tree-shaped acrylic display. The physical kit gives children a place to keep and collect letters after receiving them through the service.
Letters come to life in AR.
Scanning a physical card opens an AR experience. The card connects the letter exchange to educational content, mini-games, and immersive scenarios, while the acrylic tree keeps the correspondence present as a physical collection.
