JAKARTA - Around 40 stations and commercial buildings in Japan have introduced an artificial intelligence (AI) system to prevent suicides that have helped save at least 2 lives, according to its developer.
Tokyo-based Asilla Inc. created the system, which assesses the likelihood of someone jumping to their death by analyzing behavior captured by security cameras at stations and buildings, such as pacing or lingering near the edge of a station platform or roof.
Once the system detects the signs, it will notify security officers and station staff, with warnings issued through loudspeakers in some cases, Kyodo News reported (2/6).
In one case, the system detected a man in an area not entered by customers at a commercial facility and a security officer approached him.
The man then said he intended to commit suicide by jumping, according to the company.
In another case, a child was found lingering near a fence on the top floor of a facility, and a security guard discovered that the child had written a suicide note, the company said.
Asilla has worked with about 200 commercial facilities and other entities since 2022 to train its AI system using about 7 million security camera recordings, making it capable of detecting not only signs of suicide but also cases of illness and inability to move as well as violence.
According to the company, the system has been introduced at around 30 commercial facilities and about 10 stations in Tokyo and the neighboring Kanagawa Prefecture.
