    @freino made a web-based 3D-touch demo that prints the value in question, however the javascript DOM attribute has values between 0 and 1, not 0 and 6.666667.

    Check it out with an iPhone 6s/6s+ at http://freinbichler.me/apps/3dtouch/

    Wondering how the 3d touch changes the cross platform development!?

    What happens when a developer has 2 different actions for a long press and pressured (3d touch) press!?

    I have trouble understanding the usability pov for the 3d touch! Do we really need it?

    and to think there was an api to derive pressure from contact size back in 2.0

    https://developer.apple.com/library/ios/documentation/UIKit/...

    anyone knows any app usage of this? I remember some games had pressure calculated from the accelerometer, don't know if any did use this one instead.

    I'm wondering: can it measure force also for different presses simultaneously? And how far apart do the presses need to be?

    I really would like to see google maps to make use of 3d touch to make zooming easier. Moving the finger up/down while pressing would zoom in/out. That would make one-finger usage of the maps so easy.

    I'd like to know how precisely the force sensors are calibrated during the manufacturing process, i.e. what is the variation in maximum detected pressure across iPhones?

    For more on 3dTouch, I've catalogued a dozen other articles here:

    By the way, over the weekend I added a Swift Weekly view, which should be a nice way to keep up on new Swift blogs:

    How does pressure sensitive touch essentially differ from a long touch?
