![]() "I have read about this idea of a Taptic Engine in the Apple Pencil before and I agree it would be an awesome addition to the Apple Pencil user experience. There are, of course, technical challenges: The Pencil's battery life would most certainly take a hit with a Taptic Engine onboard, and Apple would have to do a fair amount of development to squeeze correctly-sized internals into the Pencil's circular body.īut were the company to solve this issue, it could not only help artists and writers have a better experience on the iPad Pro - the technology could be a huge boon for developing accessories for accessibility, too.Ī backer of my PaperLike campaign asked me to comment on this blogpost, here what I answered him: In short, displays that feel like anything the app wants them to feel like.įor Pencil, microscopic rumbles as you draw could help simulate the feel of paper, or canvas, or other surfaces in a way altering the screen itself couldn't, and because the Taptic Engine is software-controlled, you'd be able to tweak it to your personal preferences on your iPad. You can look back at some of the original research conducted at MIT in 1995, Computational haptics : the Sandpaper system for synthesizing texture for a force-feedback display to get a sense of just what could eventually be possible. Taptic technology is a long-running project at Apple. But what if, instead of adding it to the iPad, Apple were to build a tiny Taptic Engine for the Apple Pencil itself? The iPad Pro screen has long proven difficult to build a properly-functioning Taptic Engine into because of its size. The company already has "Taptic" technology that it's used for 3D Touch and Force Touch on the MacBook Pro trackpad, and has reportedly experimented with using it to simulate virtual keyboards and other, more subtle movements in games. There is another, better way - but it requires Apple to put the effort into its technology. Worse, it's hard to iterate on that if it doesn't perfectly work for you: If Sapper's screen protector provides too much drag on the Pencil, you then have to choose between having lots of friction (screen protector) or none at all (glass screen). Screen protectors and nib tweaks can adjust that feeling somewhat, but they're still striving for a sensation that's almost impossible to replicate. The Pencil doesn't actually feel like drawing on paper because our brains have a recorded notion of what drawing on paper feels like - and no stylus can currently compare. When we talk about styluses being too slippery or too slow, what we're really talking about is the haptic feedback our brains receive get as a result of using a tool against the screen. How do you solve a problem like haptic feedback? But even the best screen protector in the world is still an addition to your iPad - it's a jury-rigged fix for a more troublesome problem. I don't doubt that Sapper's screen protector helps with the drawing experience I've tried a number of various screen protectors on my iPad, all of which add a bit of drag when working with my Pencil. ![]()
