MOBILE TERMINAL, WEARABLE TERMINAL, SONIC DISTANCE MEASUREMENT SYSTEM, AND SONIC DISTANCE MEASUREMENT METHOD |
摘要 |
Disclosed herein is a mobile terminal including: a reproducing section adapted to reproduce a first distance measurement signal; a recording section adapted to record the first distance measurement signal and a second distance measurement signal output from other mobile terminal; a time difference measurement section adapted to measure a first difference between recording start times of the first and second distance measurement signals; a communication section adapted to receive a second difference between recording start times of the first and second distance measurement signals from the other mobile terminal, the second difference being measured by the other mobile terminal; and a distance calculation section adapted to calculate a distance to the other mobile terminal by multiplying the subtraction result between the first and second differences by the speed of sound. |

1. A mobile terminal comprising:
a reproducing section adapted to reproduce a first distance measurement signal; a recording section adapted to record the first distance measurement signal and a second distance measurement signal output from other mobile terminal; a time difference measurement section adapted to measure a first difference between recording start times of the first and second distance measurement signals; a communication section adapted to receive a second difference between recording start times of the first and second distance measurement signals from the other mobile terminal, the second difference being measured by the other mobile terminal; and a distance calculation section adapted to calculate a distance to the other mobile terminal by multiplying the subtraction result between the first and second differences by the speed of sound. |
