I think this is what would be a really great extension for many people.
It would be so cool if i could write with my apple pencil on the touchpad of my macbook pro - for example to create formulas without the hassle of patching them together using latex.
Of course there are tools to convert hand written formulas into a digital representation, but writing using a mouse is just too complicated and takes too much effort.
So in my vision, the touchpad should be somehow able to locate the tip of the pencil even if it is 1 cm above the touchpad, so that the position of the tip gets rendered at the corresponding position on the screen.
So you could use one hand for writing using a pen and the other hand to zoom in and zoom out etc.
That would be really cool. What do you think?
