US Patent 10250870 Adjustable virtual reality device capable of adjusting display modules

An adjustable virtual reality device includes a first display module, a first image capturing unit, a second display module, a second image capturing unit, a lateral driving module, and a control unit. The first display module and the second display module display a first image and a second image, respectively. The first image capturing unit and the second image capturing unit detect two positions of two pupils of two eyeballs, respectively. The control unit calculates a pupil distance between the two pupils according to the two positions of the two pupils and controls the lateral driving module to drive the first display module and the second display module to move in a lateral direction, so that a lateral distance between the first display module and the second display module is corresponding to the pupil distance, which enhances comfort in use.
