"I killed the Newton because of the stylus. If you're holding a stylus, you can't use the other five that are attached to your wrist."
- Steve Jobs
Steve Jobs (2015) movie; I have no idea whether he really said that
Newton was killed in 1998 and this 1996 video from Star Trek: The First Contact may hint where visionary Steve Jobs get the idea from (Although, famous 1993 "You Will" commercial of AT&T also showed touchscreen used by finger).
While our Android/iOS smartphones are just a decade old, googling revealed that the first finger-driven touchscreen was invented by E.A. Johnson in 60s, when Star Trek was using colorful glass buttons.
But, I don't believe that it didn't appear in Sci-Fi world first.
What is the first reference in Sci-Fi to a touch-screen computer interface?
This question has some earlier touchscreen references, but it's not clear that they are finger driven.
Which Sci-Fi work introduced the idea of "Touchscreen used by fingers"?
