Abstract

A wearable positioning device includes an inertial sensor, a storage device and a processor. The inertial sensor senses an acceleration signal and an angular velocity signal. The storage device stores a previous positioning signal and a current coordinate. The processor is electrically connected to the inertial sensor and the storage device. A wearable positioning method is executed by the processor, which includes: determining whether the wearable positioning device is in one of an under-water mode and an above-water mode according to a pressure sensing signal; calculating, when in the under-water mode, a current acceleration and a current direction according to the acceleration signal, the angular velocity signal, and a swimming posture signal representing a swimming posture; and calculating a current positioning signal according to the current acceleration, the current direction and the previous positioning signal, and updating the current coordinate with the current positioning signal.
