Apple's "feedback coordination of virtual interaction", a patent approved in September 2020, focuses on things you don't realize in real life. Apple said in its patent that the music processing system It is best to strive to improve the time accuracy of music performance in order to improve the music quality and user experience. This task, called quantization, may involve presenting different playback of sound at different times.
According to Apple's proposal, depending on the artist or where you stand, you only hear music when you should. Apple hopes that accurate audio can change what you hear little by little according to your location.
The solutions proposed by apple are all for head mounted display (HMD), and they also pay attention to the audio itself and the physical location of the wearer. The patent not only describes detecting the position of the HMD wearer to change the sound, but also includes when the wearer generates the sound.
Another patent, first granted to apple in 2020, now appears in the form of a slight modification, which is called "structural thermal solution for display devices". It focuses on keeping the wearer cool. Some display panels, such as OLED and uoled panels, generate heat when working for a long time, making the wearer uncomfortable. Apple hopes to integrate heat dissipation solutions into structural components to solve the problem.
This design not only reduces the number, complexity and weight of the overall components of the display system, but also increases the thermal conductivity and improves the thermal management, so as to reduce the working temperature and prolong the service life of the system. This is not to say that Apple has any special new ways to dissipate or reduce heat. Instead, the company aims to use existing hardware to facilitate the transfer of heat from the display panel.
