DETECTION OF ABNORMAL EVENT IN TOILET
1. DETECTION OF ABNORMAL
EVENT IN TOILET
Kayo Yoshimoto, Maki Takeda, Nagisa Sasaki,
Takeshi Ando, Sachiko Shimizu, Kenji Yamada, and Yuko Ohno
Osaka University
Warning!
2. Background
Inner toilet
• Toilet in Japan
?
Unknown…
Closed space
No gap Delay detecting abnormity
Toilet activity
High risk of falls
Need for detecting abnormal event
in toilet automatically
3. Proposed System
Original image Calculating
Camera center of gravity
Warning! Nurse
Protect privacy
Detailed information
Purpose
Examine whether the system can distinguish
the patient’s conditions
Normal Fall Unconsciousness
4. Experiment
Five scenarios
• Normal action
• Fall action(Three types)
• Unconscious action
The center of gravity during fall action
Sit on the seat Fall
(Static state) (Static state)
5. Summary
We proposed a non-contact system to detect
abnormal event in toilet.
• The experiment simulated behaviors of the patient in toilet
was showed.
• The experimental result showed the proposed system could
distinguish the patient condition by using the position of
center of gravity.
Future research
Effectof individual variability
Improvement of more privacy
