One of the iPhone 5's groundbreaking features was the Touch ID fingerprint sensor, which helps eliminate the need for passwords. The iPhone 6s/6s Plus upped the ante with the 3D Touch feature. So when will the Touch ID/3D Touch sensor make it to the Mac's keyboard/mouse/touchpad?
Touch ID offers a way to securely unlock your iPhone with the touch of a finger. Built into the home button, it uses a laser cut sapphire crystal, together with the capacitive touch sensor, to take a high-resolution image of your fingerprint and intelligently analyze it to provide accurate readings from any angle.
The Touch ID sensor recognizes the touch of a finger so the sensor is only activated when needed, preserving battery life on the iPhone. Touch ID can also be used as a secure way to approve purchases from the iTunes Store, App Store or iBookstore.
Imagine being able to do this on your Mac with a keyboard, mouse or touchpad built with a Touch ID sensor. No more having to remember passwords every time you log onto the Mac App Store, iTunes Store, iBookstore or Newsstand. It would also add an extra layer of protection for stolen Macs.
3D Touch senses how much force you apply on the screen. For example, on the iPhone 6s' Home Screen, you can press down on an app's icon to quickly interact with the app. This feature is called Quick Actions. Pressing on the Phone app allows you to quickly call a recent contact. Pressing down on the Camera icon allows you to take a selfie.
Inside of apps, 3D Touch allows users to "Peek" and "Pop" into their content. Press lightly to "Peek" at a photo, email, web page or other content, and press a little deeper to "Pop" into the content itself. With Quick Actions, 3D Touch provides shortcuts to the actions you undertake the most.
Imagine these features on new Macs. Perhaps Apple is working on this for upcoming revs of the iMac, Mac Pro, Mac mini, MacBook Air, and MacBook Pro.
Or perhaps Apple will just implement Touch ID/Force 3D sensors into a touch-enabled Mac screen -- though, realistically, the odds of seeing such a device are slim to none.
