Patent Searching and Data


Title:
CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/233870
Kind Code:
A1
Abstract:
An estimation unit (12) estimates whether a person is present inside a door on the basis of sound data acquired by an acquisition unit (11). The wording "inside a door" refers to a place where a user takes off his or her shoes in an entryway and a place where the user who has taken off his or her shoes enters into a room. A setting unit (14) sets an entry-prohibited range for a drone (10) by using the position of the door as a reference. More specifically, the setting unit (14) sets a wider entry-prohibited range when it is estimated that a person is present inside the door than when it is estimated that a person is not present inside the door.
