Wetterbank® is a bench that starts conversations between strangers, by helping them file complaints about the weather.
A design fiction asking how autonomous systems will shape our encounters in public space, as they move from our homes onto our streets.
Wetterbank® is a design fiction and an ongoing research project. The bench does not exist. Yet.
How it adds up.
Three things everyone at a German tram stop already knows.
- The weather is the safest way to start a conversation.
- +The tram is late. Again.
- +Nobody at the stop says a word.
- =A bench that speaks first.
Wetterbank® started as a design fiction on my portfolio. This site is where it continues.
File a weather complaint. Live · try it
Complaints are processed in the order they are received. Trams are not.
The bench does not exist, and a whole bench can’t be prototyped on a website. So this form stands in for it: a small piece of the bench you can actually try. You speak first, and the bench answers in its own voice.
- What it replaces
- The moment at the tram stop when the bench replies. The form takes the place of the bench’s ears, and the replies are its voice.
- How it answers
- It reads what you choose and write (the category, words like “umbrella” or “Monday”, your tram line, the time of day) and picks a reply that fits, after a short typing pause. No AI and no server: just rules and a stack of pre-written replies.
- Why this tone
- Polite, bureaucratic and slightly sarcastic, like a public office that takes the weather very seriously. Sounding like an official makes it clear the bench is a machine, not a person pretending.
- What it tests
- How it feels when an object answers back. Funny, helpful, annoying? From the second complaint on, it starts pointing you towards the person next to you, just like Modes 2 and 3.
- What it keeps
- Nothing. Complaints are not stored or sent, and the conversation clears itself after 30 seconds.
Three modes, one step at a time.
Strangers at a tram stop rarely start talking on their own. Wetterbank® helps in three small steps. Each mode moves a little further from the safe topic and a little closer to the person next to you. The bench only moves on when people respond, and its last step is to go quiet.
Weather · Mode 1
It opens with the safest sentence there is.
- What happens
- Someone sits down in the rain. The bench makes one remark about the weather. No questions, no names, no follow-up.
- Why
- The weather is the one topic everyone shares and nobody owns. It is easy to answer and just as easy to ignore, so nobody feels put on the spot.
- What to watch for
- Does anyone answer at all? A laugh, a sigh or an eye-roll already counts.
- What comes next
- If someone reacts, the bench moves on to Mode 2. If nobody does, it stays quiet.
Complaints · Mode 2
It takes your complaint and forwards it. Grumbling together is a small bond.
- What happens
- The bench invites a complaint (the late tram, the wet socks) and “forwards” it to the cloud, with a case number and a reply time nobody believes.
- Why
- Complaining together puts people on the same side. The person next to you hears the complaint, and probably shares it. The joke is about the tram, not about either of you.
- What to watch for
- Do the two people start reacting to each other, not just to the bench?
- What comes next
- Once both have grumbled about the same thing, the bench has its excuse for Mode 3.
Names · Mode 3
It drops the weather and asks for a name.
- What happens
- The bench points out what the two have in common and suggests they introduce themselves. Then it says nothing more.
- Why
- A bench you keep chatting with is just a smart speaker outdoors. The aim is for people to talk to each other, so the bench steps out of the way.
- What to watch for
- Does the conversation carry on without the bench? That is the only result that counts (see A and B below).
- What comes next
- Nothing. The bench stays quiet unless someone speaks to it again.
In short: the weather gets people talking, the complaints put them on the same side, and the names hand the conversation over to them.
The question.
How do interactive and autonomous systems shape social encounters in public space?
- Want. Do strangers at a tram stop want to talk at all? And if they do, to each other or to the bench?
- Help. When a bench speaks first, does it open a conversation between people, or quietly replace it?
- Future. How will we respond once talking objects are an ordinary part of public space, and should they be?
From a distance, A and B look the same: someone at the bench is talking. But only B is what Wetterbank® is for. A bench you chat with is just a smart speaker outdoors. So every study records the two separately, and compares both with an ordinary bench that says nothing.
Wetterbank® doesn’t exist yet. Should it?
The documentation follows the question: what came before, how it will be tested, and what happens next.

Famous benches.
Ah, if only they could talk.
-
Forrest Gump 1994
A bus stop bench in Savannah. He tells his whole life story to strangers, who let their buses go.
Wetterbank® would have said: “Your bus left. Please continue.”
-
Good Will Hunting 1997
A park bench in Boston. A therapist and a student, one long conversation, no small talk at all.
Wetterbank® would have said: “Session extended. No extra charge.”
-
Manhattan 1979
A bench by the Queensboro Bridge. Two people talk until the sun comes up.
Wetterbank® would have said: “Overtime noted. Lovely dawn, though.”
-
La La Land 2016
A bench above Los Angeles at dusk. Famous on the poster. It was a film set the whole time.
Wetterbank® would have said: “Between us, I’m not even real.”
-
Paterson 2016
A bench by the falls. A bus driver writes poems on his lunch break.
Wetterbank® would have said: “Nice poem. Any complaints about the weather?”
-
(500) Days of Summer 2009
A bench above downtown LA. Where they meet, and later where they say goodbye.
Wetterbank® would have said: “Same bench, two endings. I keep the records.”
The bench in films is not just any piece of furniture: it witnesses the beginning or the end of a love story, is the set of the greatest revelations or a place of profound inspiration. (after Domus, 2019)
Decades in the front row of love, loss and genius, and not one of them ever said “Nice weather, isn’t it?”. Amateurs.
