  • Publication number: 20190250260
    Abstract: An electronic device including a sound receiver and a processor is provided. The sound receiver receives a sound signal provided by a sound generator. When the processor determines that an obstacle is blocked between the electronic device and the fixed device, the processor estimates a virtual position of the electronic device at a current time according to previous movement information and a previous position of the electronic device. The virtual position has a shortest path between a boundary position of the obstacle and the sound generator. The processor obtains a first relative distance between the electronic device and the boundary position according to the sound signal received by the sound receiver and the boundary position. The processor calculates a relative velocity and a relative acceleration of the electronic device relative to the fixed device at the current time according to the sound signal and the first relative distance.
