说明与用途

Gramina 将户外散步转化为使用本地 AI 的虚拟邮票收藏体验，屏幕时间极短。

问题

Developers spend excessive screen time; need an activity that encourages outdoor engagement while leveraging AI.

结果

Gramina delivers a short‑screen, outdoor‑focused experience that uses on‑device AI to transform real photos into collectible stamps and postcards, preserving privacy and incurring zero operational cost.

工作流

• 1. Put phone in pocket and step outside.
• 2. Capture a quick photo of a grass patch.
• 3. On‑device AI (Gemma) classifies the specimen, extracts color histograms, computes a Touchability Index, and generates botanical lore.
• 4. Mint the photo into a perforated postage stamp with realistic ink cancellation stamped with date and coordinates.
• 5. Mount stamp on a double‑sided vintage field postcard, flip it in 3D, add handwritten notes, and export or print.
• 6. Add observation to a botanical passport album and increment outdoor streak.

证据

Gramina turns outdoor walks, hikes, and park visits into a delightful botanical philately adventure where screen time is under 10 seconds
