A recently granted patent (Publication Number: US11921294B2) describes a unique head-mounted display system that includes a main body capable of generating display images, a belt for securing the main body to the user's head, and various sensors and units for monitoring and adjusting the device. The system features a first sensor to detect the fastening strength of the belt, a storage unit to store user-selected settings for the fastening strength, and a drive unit that adjusts the belt based on the sensor readings and user preferences. Additionally, an acceleration sensor and impact detection unit are incorporated to identify sudden movements or impacts, with the drive unit automatically loosening the belt in response to detected impacts to ensure user safety.

Furthermore, the patent includes claims for a method to adjust the head-mounted display, involving detecting the belt's fastening strength, fastening the belt according to user-defined settings, monitoring acceleration and impact on the device, and loosening the belt in the event of detected impacts. The system also integrates a control unit that can assess the symmetry of the user's eyes and adjust the belt accordingly for optimal positioning and comfort. Notably, the drive unit is designed to release the belt entirely in case of significant impacts, ensuring the device can be safely removed from the user's head during unexpected events. Overall, this patented technology aims to enhance user experience and safety in the use of head-mounted displays through intelligent monitoring and adjustment mechanisms.
