Abstract
An HMD system including an image data module, which includes an enabling unit and a data unit, as well as a display module that can be mounted on the head of a user and is connected to the image data module via a bidirectional communication channel. The enabling unit transmits an enabling request to the display module via the communication channel, and the display module transmits an enabling code via the communication channel in response to the enabling request. The enabling unit verifies the validity of the enabling code, prevents transmission of image data from the data unit to the display module if an invalid enabling code is present and allows transmission of image data from the data unit to the display module if a valid enabling code is present. The display module presents an image based on the transmitted image data to the user wearing the display module on his head.
