Abstract
An apparatus and a method for measuring distance by using electronic devices are provided. The apparatus includes an output unit, an input unit, and a controller. The output unit may be configured to transmit the first sound wave, and the input unit may be configured to receive the second sound wave from another apparatus that receives the first sound wave. The controller may be configured to determine the distance between the apparatus and the another apparatus based on a first value and a second value. The first value may correspond to a difference between a timing of initiating a transmission of the first sound wave and a timing of receiving the second sound wave, and the second value may correspond to a difference between a timing when the another apparatus initiates the transmission of the second sound wave and the timing when the another apparatus receives the first sound wave.
