Your way out, drawn on the plan.

1. In a hotel abroad, the evacuation plan on the wall is in German. Where is your way out? On screen: the photo of the plan, dimmed.
2. Photograph the plan when you arrive. Or open one of 203 real plans from 24 countries and regions. On screen: the HereOut start page at phone size, in a phone frame, with its photo button and three sample plans. A hand pointer taps the small phone below them.
3. Muse Spark finds the exits. Meta's model reads the photo and points to each exit. On screen: the evacuation plan of a hotel floor in Dresden opens, dimmed. Green exit marks 1 to 3 grow in one by one, and the strip above the plan lights “Exits”.
4. Code draws the ways out. It finds the walls in the ink and links the rooms to the exits. On screen: glowing green lines grow out from the exits along the corridors. The strip lights “Ways out”.
5. You tap where you stand. The start always comes from you, not from the model. On screen: “Tap where you stand” on the plan, then a hand taps the long corridor. A ring shows the tap, and a blue line draws to Exit 2.
6. The route to the nearest exit. Your browser finds it in a moment, on the phone. On screen: a blue dot at the tap, and a blue line from it to Exit 2. A card under the plan shows “Exit 2 · Step 1 of 2” and the first step.
7. One step at a time. Walked steps turn grey. The speaker reads each one aloud. On screen: a hand taps the next button, and the card moves to step 2. The walked part of the route turns grey, and a ring marks Exit 2.
8. Exit blocked? Tap “If blocked”. The route switches to the next exit. On screen: a hand taps the “If blocked” exit button under the plan; the plan comes back with the dot still in the corridor, and the route draws in to Exit 3.
9. Muse Spark reads the words on the plan too. The plan's instructions in English, with the German original under each one. On screen: “What the plan says” under the plan: the title, the instructions and the start of the legend in English, each with its German text under it.
10. The card comes in 13 languages. Here: Korean. The steps and the labels change too. On screen: a hand taps the language menu. Then the step card, the strip above the plan and the legend are in Korean.
11. Muse Spark checks its own exits. Doubtful exits get a second look on numbered, zoomed crops. Here: 2 moved, 1 dropped. On screen: a plan from Moscow with what Muse Spark read drawn over it: the floor box and its exit points. Then the sheet of three numbered crops opens larger, with “Moved”, “Dropped” and “Moved” under the crops.
12. In a test, HereOut found about half the exits. About half of the exits it marked were wrong, so check every route against the plan. On screen: a hand taps the middle hall of the Moscow plan. Then the route to Exit 3 shows, and under the plan the line “Check the route and the exits against the plan.”
13. HereOut. hereout.devrives.com. Exits and plan words: Muse Spark, through Baseten. Walls: HereOut's own code. Routes: in your browser. Built solo for the Meta hackathon. On screen: the end card with the HereOut logo.
