    Abstract: Head-mounted display apparatus and login method thereof are provided. The head-mounted display apparatus includes an image capturing device, a pico-projector, an application specific integrated circuit (ASIC), and an application processor. The image capturing device captures a first eye image and a plurality of second eye images corresponding to a locus image. The ASIC determines whether the first eye image passes an iris recognition test. The application processor controls a pico-projector to project the locus image when the first eye image passes an iris recognition test, and generates a pupil locus based on the plurality of second eye images. The application processor determines whether the pupil locus is compliant with the locus image, and allows a login request if the pupil locus is compliant with the locus image.
