Abstract: We have proposed the fall detection method using acceleration and angular velocity sensor in android device as well as pulse wave sensor in other device. Acceleration and angular velocity are measured by smartphone's sensors while pulse wave is measured by an external sensor. The application software for detecting the start to fall using smartphone, and the ubiquitous pulse wave sensor that can measure a human pulse even during fall motion was developed successfully.
