How 3D, AR, Gyroscope, and Privacy Tech Are Redefining Mobile Experiences

As technology continuously advances, the performance ceiling of smart hardware keeps being refreshed, bringing more possibilities for internet technology applications in the future.

The following five sections analyze trends in technology application fields, including terminal 3D application technology, augmented and mixed reality technology, gyroscope technology, privacy protection technology, and multi‑screen collaboration technology.

1. Terminal 3D Application Technology

With the continuous enhancement of terminal device performance and the optimization and popularization of 3D technology, 3D applications on terminals are becoming increasingly common, offering users better experiences and greater convenience.

Currently, there are two main ways to apply 3D technology on terminals: post‑modeling rendering and real‑time scanning powered by strong device performance.

1.1 Case One: DeWu 3D Space

DeWu showcases shoes in a 3D space where users can rotate, zoom, and view details from 720° angles, creating an immersive shopping experience. The implementation involves scanning to create a model, importing it into the app, and rendering it with an engine for interactive human‑machine interaction.

1.2 Case Two: 3D Scanning App Canvas

Canvas utilizes the LiDAR scanner of the iPad Pro to scan indoor spaces and automatically renders a complete 3D model for interactive manipulation. As smart hardware continues to upgrade, future 3D applications will bring even more possibilities.

2. Augmented Reality and Mixed Reality Technology

Augmented reality overlays virtual information onto the real world, while mixed reality integrates real scenes into a virtual environment. Although these technologies may seem distant, they are already widely applied and are expected to continue evolving.

2.1 Case One: Alipay AR Red‑Packet Grab

During the Chinese New Year, Alipay uses an AR red‑packet activity to achieve marketing goals. Users scan real‑world scenes with their phone cameras to find virtual red packets, overlaying virtual information onto everyday environments.

2.2 Case Two: Google Bare‑Eye 3D Video Calls

At the 2021 Google I/O, Google unveiled a bare‑eye 3D video‑call technology called “Magic Mirror,” which uses light‑field displays to render participants with volume, depth, and shadows, making them appear as if sitting in front of you.

If mature, this technology could enable remote meetings or calls with distant family and friends that feel more realistic and warm than traditional video calls.

3. Gyroscope Technology

The gyroscope, originally used for stabilizing helicopter models, now powers motion and gesture control in smartphones and other mobile devices, enhancing user experience and interactive fun.

3.1 Case One: Alipay Ant Forest

In the Ant Forest interface, horizontal swiping reveals hidden content on both sides. The gyroscope enables lateral scene perception, adding depth and a more realistic visual feel.

3.2 Case Two: Ziru Dynamic Banners and Quark Browser

Ziru adds gyroscope interaction to traditionally static banners, creating more engaging visual experiences.

Quark Browser’s “World Emoji Day” feature lets emojis roll in response to phone shaking, adding playful interactivity.

4. Privacy Protection Technology

As technology advances, personal data becomes increasingly exposed, prompting stronger user awareness of privacy protection. Recent incidents, such as the Didi data security breach, highlight the importance of robust privacy safeguards.

4.1 Case One: MIUI Privacy Enhancement System

MIUI 12.5 introduces clipboard protection, differential‑privacy‑based location fuzzing, and file sandboxing, limiting apps from automatically reading clipboard content and blurring precise location data to improve privacy security.

4.2 Case Two: iOS Privacy Security Features

Due to its ecosystem, iOS generally offers stronger security than Android. Starting with iOS 14, Apple added visual indicators: a green dot shows camera usage, and an orange dot shows microphone usage, helping users easily perceive permission status.

5. Multi‑Screen Collaboration Technology

As terminal devices proliferate, multi‑screen collaboration becomes crucial. This distributed technology enables cross‑system and cross‑device cooperation, allowing phones, tablets, and computers to share resources and operate together seamlessly.

5.1 Case One: Foldable Screen Design

Beyond foldable screens, OPPO’s stretchable screen expands a normal phone size into a larger display through physical deformation.

5.2 Foldable Screen Design Principles

Interface design must consider cross‑device distributed interaction. Designers need to adapt UI for multiple terminals to achieve seamless multi‑device experiences. The following six adaptation principles guide effective multi‑screen design.

5.3 Case Two: Huawei HarmonyOS

HarmonyOS leverages the concept of “everything connected,” enabling interaction between mobile devices and smart home appliances.
