Abstract

A virtual reality device, including a first sensor, a second sensor, a processor, and a display screen, is provided. The first sensor senses a first rotation-amplitude corresponding to the virtual reality device, and outputs a first sensing signal corresponding to the first rotation-amplitude. The second sensor senses a second rotation-amplitude corresponding to the user'"'"'s eyes, and outputs a second sensing signal corresponding to the second rotation-amplitude. The processor generates a panoramic image, and obtains an initial display picture. The display screen displays the initial display picture. The processor further outputs a first display picture according to the first sensing signal and the second sensing signal, and the display screen displays the first display picture.
