In the realm of mobile technology, 3D Touch stands out as a revolutionary feature that adds a new dimension to user interaction. Introduced by Apple in 2015, it utilizes pressure sensitivity to offer a more interactive and intuitive experience. It allows users to interact with their devices in ways previously unavailable, enhancing the user interface (UI) with additional functionality and control. With 3D Touch, simple taps transform into a dynamic interaction that can lead to more nuanced actions like shortcuts, previewing content, and invoking hidden menus.
While 3D Touch has been discontinued on newer models, it has paved the way for similar technologies, such as Haptic Touch, which aims to replicate its functionality in a different form.
This article will explore the inner workings of 3D Touch, its features, benefits, applications, and its impact on mobile technology.
This is a pressure-sensitive touchscreen technology that enables a device to detect how hard you press on its screen. This feature creates a more interactive experience by enabling users to access additional options, shortcuts, and menus with different levels of pressure, offering a deeper level of interaction beyond just tapping or swiping.
In 3D Touch-enabled devices, such as the iPhone 6s and later models, the technology senses the force applied to the screen and provides haptic feedback—vibrations that simulate the feeling of pressing a physical button. This allows for more dynamic actions, such as:

The technology behind 3D Touch involves a combination of sensors, actuators, and software algorithms. The most notable components of 3D Touch are:
The iPhone screen is equipped with multiple layers of sensors that can detect varying amounts of pressure. These sensors are part of a capacitive touchscreen, and they measure the force applied by the user’s finger. When pressure is applied, the screen reacts by detecting the change in capacitance and converting it into a corresponding action.
Once the pressure is detected, the Taptic Engine, Apple’s haptic feedback mechanism, sends vibrations or “taps” back to the user, giving a sense of physical feedback. This allows users to feel the difference between a light tap and a deep press.
The iPhone’s iOS operating system has built-in features that leverage the data from pressure sensors. It maps different pressure levels to specific actions, such as opening an app with a soft tap or revealing a contextual menu with a harder press.
The unique functionality of 3D Touch offers several notable features that distinguish it from traditional touchscreen technology.
One of the signature features of 3D Touch is Peek and Pop. This feature allows users to preview content (peek) with a light press and fully open or interact with it (pop) with a stronger press. For example:
This method allows for quicker navigation and a more seamless experience, reducing the need to navigate through several layers of content.
Another major benefit of 3D Touch is Quick Actions. These actions allow users to access common tasks directly from the app icon on the home screen, without having to fully open the app. For example:
Quick Actions improve efficiency by allowing faster access to frequently used features.
This is also integrated with Live Photos, allowing users to animate the photo by pressing down on it. When you press lightly on a Live Photo, it comes to life with a short animation, giving users a more dynamic viewing experience.
Many third-party apps also use 3D Touch to provide additional functionality. For instance:
It introduced several benefits that enhance the mobile experience and streamline daily tasks.
The ability to access shortcuts, previews, and additional options directly from the screen enables users to complete tasks more efficiently. This can save significant time and reduce the need to navigate through multiple menus.
By providing haptic feedback, this adds a layer of tactile response to the interaction, making the user experience feel more intuitive. The pressure sensitivity allows users to feel more in control when interacting with their devices.
3D Touch’s Peek and Pop feature improves navigation within apps by letting users preview content without fully opening it, making it easier to browse and interact with content on the go.

Games with 3D Touch integration allow for more dynamic controls, with players able to control the intensity of their actions depending on the pressure they apply to the screen. This provides a more immersive and intuitive gaming experience.
For users with motor impairments, it provides an alternative method of interaction. By varying the pressure, users can interact with their device more easily than relying solely on taps or swipes.
Apps designed for productivity, such as Microsoft Office or Google Docs, leverage 3D Touch to offer quick access to tools like formatting options, document navigation, or previewing files.
Apple discontinued 3D Touch starting with the iPhone 11 series in favor of a simpler alternative, Haptic Touch. While Haptic Touch does not offer the same pressure sensitivity as 3D Touch, it mimics the behavior of 3D Touch by providing feedback and triggering actions when you press and hold on the screen.
While Haptic Touch cannot fully replicate the depth of interaction offered by 3D Touch, it retains some of the essential functionality like Quick Actions and Live Photo previews, providing a similar, though more basic, experience.
In conclusion, 3D Touch was a groundbreaking technology that redefined the way users interact with their mobile devices. By adding pressure sensitivity and haptic feedback, this allowed for more intuitive and efficient navigation, providing users with advanced features like Peek and Pop, Quick Actions, and better integration with apps. Although it has been replaced by Haptic Touch in newer models, this remains a significant part of mobile technology’s evolution. As we continue to push the boundaries of user interface design, technologies like 3D Touch have laid the groundwork for more immersive and interactive devices.
3D Touch is a pressure-sensitive touchscreen technology that allows for interaction based on the force applied to the screen.
It uses pressure sensors to detect the amount of force applied to the screen and triggers corresponding actions, like Peek and Pop or Quick Actions.
3D Touch detects varying levels of pressure, while Haptic Touch only responds to a long press and provides haptic feedback without pressure sensitivity.
iPhones from the iPhone 6s to the iPhone XS Max feature 3D Touch.
Peek allows you to preview content with a light press, while Pop fully opens it with a deeper press.
The Taptic Engine is the haptic feedback mechanism used in 3D Touch that provides vibrations or taps when interacting with the device.
Yes, 3D Touch enables more dynamic and responsive controls in games by adjusting actions based on the pressure applied to the screen.
No, newer iPhones use Haptic Touch instead, which provides similar functionality but lacks pressure sensitivity.
