Sofía in Valencia and Léa in Lyon were lab partners without ever sharing a bench – until they did, inside a shared photoreal city twin where the tram schedules were real, and the accents were, too. “Your campus bakery is dangerous,” Léa typed, crumbs obvious even in avatar form.
Departments want richer exchange experiences but can’t fly every week. Practicals, placements and local context are hard to share across borders.
How it Works: Universities co‑author modules inside a city twin that blends campus, labs and neighbourhoods. HAL8122™, BizzTech’s Agentic AI, handles time‑zone‑smart schedules, multilingual captions and assessment logistics, including identity checks via eIDAS. Local datasets (mobility, energy, heritage) become fieldwork without flights; partner firms host micro‑projects students can walk to virtually.
Why it Matters: Mobility becomes more than travel; it becomes perspective. Students learn with, not just about, peers. Costs fall; inclusion rises. Sofía and Léa finally meet IRL at graduation – with a portfolio that already spans two cities.
EU‑by‑Design: Clear controller/processor roles, joint‑degree assessment integrity, GDPR‑compliant cross‑border data flows, and accessible multilingual UX. Academic recognition is auditable, not arguable.
