Abstract
A new safety support system has been developed to detect and transmit notification of a wandering elderly person's location. The system employs a low transmitting power mobile phone (PHS) and a personal computer (PC). The PHS is carried with the elderly person as a pendant. The PHS location is identified within 100 m from the receiving antenna ID. Therefore, the system can detect whether the wandering elderly person is in or out of their home. When the wandering elderly person is away from home, the system automatically informs the caregiver via voice mode and sends the wandering elderly person's location map by e-mail.
AI evidence extraction
Structured fields below were generated from the paper’s abstract and metadata to make the evidence easier to inspect. Automated extraction may be incomplete or incorrect; verify important details against the original paper.
Main findings
A safety support system using a low transmitting power mobile phone (PHS) carried as a pendant can identify the device location within about 100 m of a receiving antenna ID, enabling detection of whether an elderly person is in or out of the home and automatic caregiver notification with a location map.
Outcomes measured
- location detection/identification within ~100 m of receiving antenna ID
- detection of in-home vs out-of-home status
- automatic caregiver notification via voice mode
- sending location map by e-mail
Limitations
- No health outcomes assessed; describes a technical system for location detection and notification
- No information on frequency, SAR, or quantitative exposure metrics
- No sample size or evaluation results reported in the abstract
