Apple is expected to launch an extended reality head-mounted display device in 2023, but the price may be between 2000-3000 US dollars. Citing foreign technology media Patently Apple, Apple has recently obtained a patent for the Gyroscopic Precession Engine (Gyroscopic Precession Engine) of an HMD (head-mounted display), which may be equipped in future head-mounted display devices.
According to the patent information published by the U.S. Trademark and Patent Office, this Apple patent mainly introduces the gyroscopic incoming engine of the headset. This means that the engine will process a bunch of motion data and give better haptic feedback in order to provide a better motion experience when playing games or watching movies.
Patently Apple points out that the patent document discusses an engine consisting of torque delivery, which provides better haptic feedback for immersive content. The engine can apply various levels of force to the face from multiple places on the headset, not just vibrations, while the user is immersed in the virtual world.
The patent description reads.
"The gyroscope feed engine can also improve immersive media content for movies and games by providing continuous torque/force on the user's head/neck or other body parts in sync with the visual content, such as creating the sensation of air wave pressure (e.g., from an explosion scene), creating the sensation of centrifugal force (e.g., a bumpy roller coaster or race car), head/neck/hand/wrist exercise (e.g., providing counter-torque to the user's motion) , Ergo correction (e.g., informing or guiding the user to fix poor sitting or standing posture), and providing reaction force feedback in VR applications (e.g., punching an object and feeling the reaction force on the hand/wrist)."
