The main feature of the iPhone 6s and iPhone 6s Plus is the 3D Touch display, which is able to recognize three types of pressures: a touch, a touch and a deeper touch. According to several Apple executives, including Jony Ive and Phil Schiller, this technological advance was very difficult to achieve and was in development for several years.
According Jony Ive, 3D Touch is what “galvanize our efforts throughout the company and is something we have been working for many time.” Moreover, Phil Schiller revealed that employs 96 3D Touch sensors embedded in Backlit LCD pressure and was just that it was so hard to get.
Corning was working with Apple to create a “flexible” glass that would run the 3D Touch, ensuring that:
Slides and the phone will work as usual or did. But press and 96 embedded sensors in the retina backlit screen measured microscopic changes in the distance between them and the glass. These measures are combined with signals from the touch sensors to make the movement of your fingers are synchronized with the screen image.
For 3D Touch “natural feel”, Apple has introduced a táptico engine, who provide us with a physical response when you press the screen with one of the two most profound dimensions. These signals have a duration of 10 to 15 milliseconds, which at first seems rather little and I think we will not be able to identify correctly.
The Cupertino company believes the time invested in realizing the 3D Touch has been worthwhile and that will mark the way forward on touch screens. Another reason why it took so long to make it happen is they wanted to do something that users would like to use, since “if it is just a function that the test and one month later no one uses, is a huge loss of talent engineering “.
