In Tokyo, BBC journalist Paul Carter joins Finnish Deaflympian Sara-Elise Ruokonen to test transport tech that makes the city more navigable for everyone.

They start with a transparent translation screen that turns speech into text to help deaf and international visitors ask for directions and at Deaflympics Square, see an AI-powered display that transforms train station sounds into text, sign language, and visual onomatopoeia.
