Abstract
Systems and methods for detecting positions are provided. First, a reference point is recorded by a first mobile device. Then, a movement, an acceleration, and an orientation of the first mobile device are detected by at least one sensor. Then, after a predetermined time interval, a relative displacement between the reference point and the first mobile device is calculated according to the predetermined time interval, and the data detected by the at least one sensor, and the relative displacement to the first mobile device is transmitted to a second mobile device.
Claims11
A system for detecting positions, applied to a first mobile device, comprising:
- a transceiver;
- a storage unit, arranged for recording a reference point;
- at least one sensor, arranged for detecting a movement, an acceleration, and an orientation of the first mobile device;
- and
- a processing unit, arranged for calculating, in every predetermined time interval, a relative displacement between the reference point and the first mobile device according to the predetermined time interval, and the data detected by the at least one sensor, and for transmitting the relative displacement to a second mobile device via the transceiver.
A method for detecting positions, applied to a first mobile device, comprising:
- recording a reference point;
- detecting a movement, an acceleration, and an orientation of the first mobile device by using at least one sensor;
- calculating, in every predetermined time interval, a relative displacement between the reference point and the first mobile device according to the predetermined time interval, and the data detected by the at least one sensor;
- and
- transmitting the relative displacement to a second mobile device.
A machine-readable storage medium comprising a computer program, which, when executed, causes a device to perform a method for detecting positions, wherein the method comprises:
- recording a reference point;
- detecting a movement, an acceleration, and an orientation of a first mobile device by using at least one sensor;
- calculating, in every predetermined time interval, a relative displacement between the reference point and the first mobile device according to the predetermined time interval, and the data detected by the at least one sensor;
- and
- transmitting the relative displacement to a second mobile device.
