Abstract
Provided a device and method for automatically adjusting an interpupillary distance (IPD) capable of achieving a desirable automatic VR IPD adjustment effect. The device includes a base, first and second optical modules, a pupil position acquisition assembly, a transmission assembly, an IPD adjustment driving circuit, and a processor. Two ends of the transmission assembly are respectively rotatably connected to a side of the first optical module adjacent to the base and a side of the second optical module adjacent to the base. The processor is electrically connected to the IPD adjustment driving circuit and the pupil position acquisition assembly. The adjustment driving circuit receives IPD position information, and causes the transmission assembly to drive the first optical module and the second optical module to move close to or away from each other to adjust a distance between the first optical module and the second optical module.
