Abstract
A driving method suitable for a head mounted device (HMD) is provided. The driving method includes the following operations: moving a first image capture unit and a second image capture unit of the HMD to respectively capture two left-eye images and two right-eye images; calculating a first eye relief according to at least one left-eye feature in the two left-eye images; calculating a second eye relief according to at least one right-eye feature in the two right-eye images; calculating an interpupillary distance (IPD) according to the first eye relief and the second eye relief; and adjusting, according to the IPD, a distance between a first lens and a second lens of the HMD.
