I am so happy to communicate with you. Whether it is young people or the elderly, if they physically experience hand tremors, or have hand tremors because they take certain medications long-term for an illness, yet they might be highly gifted artists, painters, or in some field that requires the brain to have extremely precise control over the hands—then for them, hand tremors make them unable to display their talents and gifts, or even lose their ability to work. I know that currently, artistic creation on Apple devices, such as drawing, can achieve extremely, extremely precise control, but I feel this is actually very disadvantageous for this demographic with hand tremors (this might also just be my personal subjective view, and it might be incorrect, because I am not very familiar with Apple's current technology in this area). I was just thinking that for this group of people, when they use the Apple Pencil to create, the signals they input into the device should instead be blurred or smoothed by the device, rather than being a precise touch. I am just giving an example, because currently I have some product features I want to implement, but I was a liberal arts student before, and I am not very familiar with what APIs and tools Apple currently provides. If Apple can provide them, then I wouldn't need to develop them myself; I could just directly use this API. Because currently we are in a state of information asymmetry, I am also not entirely sure how to express it. I feel the best solution to this matter is for me to first learn more about what APIs or tools or other things Apple currently provides.Do you think so? Looking forward to your thoughts，Thanks
