Abstract: A head-mounted display includes a shell, a display generation unit, a processing unit, at least one pressure sensor, and a linkage mechanism. The display generation unit includes at least an optical engine and a mirror connected to the optical engine. The processing unit is electrically connected to the optical engine and the pressure sensor, and the pressure sensor detects an external force applied to the shell and outputs a pressure signal to the processing unit. The linkage mechanism is electrically connected to the processing unit and connected to the display generation unit. The processing unit actuates the linkage mechanism to cause the mirror of the display generation unit to move away from the user's face.

Abstract: A display system and an operation method thereof are provided. The head-mounted display (HMD) device of the display system includes a camera, a monitor, a communication circuit and a processor. The processor is coupled to the monitor, the camera and the communication circuit. The processor receives and processes sensing data provided by a motion sensor of the display system through the communication circuit, so as to obtain a motion trajectory of the user. The camera photographs a person in a view field of the user. The processor performs image recognition to the video data provided by the camera, so as to obtain a motion trajectory of the person. The processor controls the monitor to display the motion trajectory of the user or the motion trajectory of the person.

Abstract: A head-up display system includes a head-up display and an image detecting unit. The head-up display includes a first control unit, an image source, and an optical system. The first control unit is configured to correct an image signal. The image source is coupled to the first control unit and configured to output an image beam according to the corrected image signal. The optical system is disposed on a transmission path of the image beam. The image detecting unit is disposed at a side of the head-up display to detect a deviation angle of a user with respect to the head-up display. Here, the first control unit corrects the image signal in advance according to the deviation angle of the user with respect to the head-up display and according to an aberration generated by the optical system.
