3D Touch: A Guide to Apple's Pressure-Sensitive Technology

Introducing 3D Touch on the iPhone 6S
The iPhone 6S has been released, generating the typical excitement associated with new iPhone launches. However, one particular feature deserves focused attention due to its significant impact: 3D Touch.
A Revolutionary Touchscreen Technology
It is reasonable to suggest that 3D Touch represents the most groundbreaking advancement in mobile phone touchscreen technology since the introduction of gestures like pinch-to-zoom and swiping.
These actions are now commonplace, but 3D Touch introduces a new dimension of interaction.
Beyond a Simple Addition
3D Touch is not merely an added function on the iPhone 6S. It signifies a core shift in how users will physically engage with their devices.
This technology fundamentally alters the user experience, offering new possibilities for interaction and control.
The implications of this change are substantial, potentially redefining mobile interaction as we know it.
Introducing Peek, Pop, and Quick Actions with 3D Touch
Apple’s 3D Touch technology introduces new functionalities known as Peek and Pop, alongside Quick Actions.
Applying varying levels of pressure to the screen enables access to expanded options. For instance, pressing firmly on the Clock app icon on the home screen reveals choices for creating alarms, initiating timers, and starting stopwatches.

This streamlines interactions with applications, reducing steps and providing direct access to frequently used features.
Numerous third-party applications have already integrated 3D Touch. The Instagram app, for example, now features four readily available quick actions accessible directly from its home screen icon.

The “peek” functionality is another key component of 3D Touch. Pressing on an unread email allows a preview of its contents without fully opening it.

Releasing pressure returns you to your inbox. Swiping upwards during a peek reveals additional options.

Within the Mail app, this allows actions like replying or forwarding messages. The peek feature extends beyond email to links within messages, enabling website previews without launching a browser.
Furthermore, you can preview photos by pressing on thumbnails within the Camera app.

This allows for quick review of captured images, preventing interruption of the photo-taking process.
When composing messages, a firm press on the keyboard facilitates cursor movement for precise text selection.

Here are additional capabilities offered by 3D Touch:
- Preview a location by pressing on an address within a message.
- Quickly share pictures from the Photos app with a press.
- Save photos in Safari by pressing and dragging upwards.
- Swiftly switch between apps by pressing on the left screen edge.
- Create pressure-sensitive drawings within the Notes app.
- Utilize Live Photos as animated lock screens.
3D Touch presents a wealth of possibilities, and its introduction with the 6S series is just the beginning. Future applications could include accessing weapon functions in games or rapidly adjusting settings.
The potential of this technology is vast and promises to significantly alter how we interact with mobile devices.
Modifying or Deactivating 3D Touch
While 3D Touch offers a unique user experience, it might not appeal to all users. Therefore, options are available to either turn off the feature entirely or modify its sensitivity for personalized use.
Begin by opening the "General" settings on your device, then select the "Accessibility" option.

Within the Accessibility menu, choose "3D Touch". From this point, you can either completely disable the functionality or adjust the level of sensitivity to your preference.

It is anticipated that other smartphone manufacturers will soon integrate comparable features into their own devices. Currently, however, the iPhone 6S and iPhone 6S Plus are the sole devices offering this innovative capability.
