P.I.M.

Theatre as listening device.

Parktheater Eindhoven asked for something they could not buy off a shelf. A way to hear what visitors actually carry home from a performance, without handing them a five-point form they will not fill in. Their multi-year plan, Meer dan jij..., is about understanding what theatre does to people after the last applause.

We answered with a rotary phone in the foyer. A radar in the pedestal notices when a visitor lingers and rings the phone. They pick up. They talk to P.I.M. in Dutch, for a minute or so, no more than four questions. Next to the phone, a 1967 Philips CRT shows a short anonymised summary of the call as soon as the handset goes down.

For 26 days in January, 613 visitors picked up. Average call: 1:19. Zero moderation incidents across the whole run.
The brief

Build a low-friction, playful, theatrical way for visitors to share what stayed with them after a show. Turn the qualitative input into something programmers can act on by Monday morning. Make it work in a real venue, with real audiences, for a real season, without a host standing next to it.

Privacy and tone were non-negotiable. Dutch only. Names and identifiers stripped before storage. Maximum four questions. No leading questions, no script the visitor could feel.

The build

A restored rotary phone on a white pedestal. A 24 GHz radar inside notices when someone lingers. A 48-LED ring under the diffuser pulses softly while the line is open. The handset routes through an FXS bridge and a private SIP subnet into a Dutch-speaking AI agent we wrote for the theatre's tone.

The voice engine is Switch Board AI, Reckon. Studio's voice AI product. P.I.M. is the first public installation Switch Board AI powers. Parktheater wrote about it on their own page, in Dutch, with the theatre's own framing.

A 1967 Philips CRT next to the phone. The P.I.M. intro between calls. The anonymised summary of each conversation right after the visitor hangs up.

A survey gives you a number. P.I.M. gave the theatre 142% more words, and behind those words: what moved people, what bothered them, and what they took home.
