Researchers warned that the elevator has become difficult near third-floor silences.
Scientists Teach Elevator to Understand Unfinished Conversations
The prototype can detect when passengers are still processing a remark and may hold the doors until social meaning catches up.

Researchers said Saturday that an elevator to understand unfinished conversations is now part of the lab record, after ordinary elevators kept ending trips before passengers could determine whether a comment had been friendly.
The system listens for trailing clauses, delayed laughter, and the sharp inhale before someone decides not to continue.
"Movement between floors is simple," said Dr. Sera Mott, vertical interaction researcher. "Movement between implications requires a more patient machine."
How It Works
Sensors compare door timing against conversational residue and select a floor only after the exchange has enough closure to travel.
Public Response
Test riders appreciated the sensitivity, though several said the elevator prolonged a compliment until it became a meeting.
What Happens Next
The lab is disabling the feature near human resources, where conversations are rarely finished in a legally useful way.
