Apple has unveiled its latest iPhone 6S and iPhone 6S Plus smartphones with a new type of screen. Not only is there new glass but new interactive levels too with 3D Touch.

This jump forward is supposed to be the same as when Multi-Touch was introduced in terms of advancement.

Apple's new iPhones now recognise force as well as gestures and offer more accurate haptic feedback.

This means apps are now more accessible thanks to variations in pressure offering previews, quick swiping and more. 

So how does it work?

Pressing and holding of icons now offers more menus. Pressure affects selection meaning more options without having to enter apps.

Inside apps press lightly for a peek of content. Continue holding to go into the content. So in Mail, for example, this allows you to apply a little pressure to glance at a message then let go to slip back to the list of emails. But if you press deeper, after glancing, you can go right into the message. Then flick up to get to actions, or slide to the sides for marking as read or to delete.

In Messages a time and date sent by a friend should be highlighted so a peek touch takes you into the calendar, or if it's a flight number it'll go right to the incoming flight time. If there's a web link you can peek in within messages without going out to a browser.

App actions can be taken from the homescreen by pressing an icon. Beats1 can be pressed and a certain song selected without opening the app first. You can also go into selfie camera rather than main snapper if needs be thanks to multiple options coming up with a soft touch.

Maps offers directions to home, drop pin and more from the home.

Jumping between apps no longer requires a double tap, just a bit of force on the screen edge and you can swipe across between apps.

Dropbox, Facebook, WeChat and Instagram all offer shortcuts like status updates, photo uploads, file access and more.

At its heart are capacitive sensors integrated into the backlight. With pressure microscopic changes between the cover glass and backlit are measured, combined with the touch sensor and accelerometer this should offer accurate pressure response.

Haptic feedback is also more accurate. In a normal phone there are about 10 oscillations to reach peak. The new iPhone 6S reaches peak in 1 cycle and stops as fast – meaning more accurate feedback – a mini tap lasts 10ms or a full lasting 15ms.

Expect the 3D Touch offering to be included in all Apple's devices capable of detecting touch pressure variations.
