Modern smartphones, including Xiaomi devices, have long since ceased to be just a means of communication, becoming universal tools for work, creativity and navigation in the digital world. However, for people with disabilities, older users or those in specific situations (for example, driving or in the dark), the standard interface can be difficult or even inaccessible. This is where special features come to the scene, which is a set of software tools designed to make interaction with the gadget comfortable for everyone.
With Android operating systems that run on top of MIUI or HyperOS, these features are integrated at a deep level to allow you to control your device with voice, gestures, or even a glance. Understanding how these mechanisms work is not only important for people with disabilities, but also for any advanced user who wants to optimize their smartphone experience. In this article, we will take a closer look at what lies behind the term, how to activate hidden functions, and what settings are really useful in everyday life.
Many owners of Redmi and Poco phones are unaware of the potential hidden in their devices’ accessibility menus. Activating the right settings can dramatically change the usability of printing, reading text from the screen, or controlling with one hand. We’ll look at key tools like TalkBack, Switch Access, and voice control, explaining their practical applications without unnecessary technical complexity.
Main purpose and categories of accessibility
Android’s Accessibility feature is not a single switch, but a set of services, each with a solution to the interface’s adaptations. In Xiaomi devices, these tools are divided into logical groups: vision, hearing, physical interaction, and cognitive functions, which allow the user to point-to-point the device without activating unnecessary services that can consume battery resources.
For visually impaired users, there are screen readers, zoom in and color scheme changes. TalkBack, as Google’s standard screen reader, fully voices on-screen actions, describes interface elements, and allows you to control your smartphone without visual control. In addition, there are high-contrast text and color inversion settings, which are critical for people with color blindness or visual impairment.
⚠️ Warning: Turning on TalkBack completely changes the logic of touch screen management (single tap selects element, double tap activates). If you turn on this feature accidentally, you usually need to press the volume buttons on the touch screen at the same time to turn it off. 3-5 Or swipe two fingers upwards.
The category of physical interaction includes tools for those who have difficulty making precise finger movements, including eye control, voice access and switches (Switch Access) that allow you to connect external buttons or joysticks, which opens up control options for people with limited hand motor skills, making the smartphone accessible even when tremors or fingers are absent.
- 👁️ Vision: TalkBack, Select to Speak, Color Inversion, Large Text.
- 👂 Hearing: Monophonic sound, Sound amplification, Visual notifications (blinking flash).
- 🖐️ Physical interaction: Eye control, voice control, Switch Access, Touch setting.
Special attention should be paid to cognitive accessibility, which helps users with learning difficulties or focusing, features like Digital Wellbeing, blocking distracting applications and simplified startup mode help to keep focus. In new versions of HyperOS, these tools have become even more flexible, allowing you to create personalized profiles for different use cases.
Voice control and Voice Access
One of the most powerful features in Android’s arsenal is Voice Access. Unlike Google Assistant, which is a regular voice assistant that can answer questions and run apps, Voice Access allows you to have full control of the operating system with your voice. You can dictate text, scroll through pages, open menus and press buttons without ever touching the screen.
To activate this tool, you need to go to the special features settings and select the appropriate item. Once turned on, prompts with numbers or text tags next to each interactive element appear on the screen. The user simply says a command, such as "Push 5" or "Scroll down", and the system performs an action. This is an indispensable feature for situations when hands are busy or dirty.
Settings → Special features → Voice Access → Use Voice AccessThe accuracy of command recognition in Xiaomi with MIUI 14 and higher has increased significantly thanks to improved natural language processing algorithms. The system understands context and allows you to perform complex sequences of actions. However, stable operation requires a stable Internet connection or a preloaded language package for offline mode.
💡
For maximum accuracy of voice control in noisy environments, use a headset with a microphone located closer to your mouth than the smartphone’s built-in microphone.
It is important to note that Voice Access supports many languages, including Russian, but its functionality may vary depending on the regional settings of the Google account. Some commands, especially those related to navigating specific applications, may require prior training or not work in third-party launchers.
TalkBack screen announcer and screen reading
TalkBack is a standard screen reader for visually impaired people that provides voice feedback on what's going on on your device. When you activate this service, your phone starts to voice button names, text messages, battery levels, and even actions performed in apps, which turns the visual interface into an auditory one, making the smartphone fully accessible to blind users.
TalkBack is based on specific gestures: single tap selects an item (it is voiced), double tap at any point on the screen activates the selected item, and swipes with two fingers allow you to scroll through the content. There are also more complex gestures, such as drawing the letter "L" to return or "T" to call the top menu. Mastering these gestures takes time, but gives you complete control of the device.
| Gesture. | Action. | Note |
|---|---|---|
| 1 finger, 1 touch | Selection of element (voice) | Basic navigation action |
| 1 finger, 2 touches | Activation of the element | Analogue of the ordinary clique |
| 2 fingers, up/down swipe | Scrolling the page | For reading long texts |
| 2 fingers, right/left swipe | Transition between pages | It's on the main screen. |
In addition to TalkBack, Xiaomi smartphones have Select to Speak, which is less invasive and does not require a complete change in the control logic. The user can select a specific piece of text on the screen (article, message, menu), and the system will read it out loud, which is convenient for people with dyslexia or just for listening to long documents on the road.
⚠️ Warning: Don't use TalkBack all the time unless absolutely necessary. Screenreaders consume significant amounts of CPU and battery power as they constantly analyze changes on the screen in real time.
The settings for speech speed, voice tone and voice detail are set in the TalkBack settings menu. You can choose different speech synthesis engines if you don't like the standard Google TTS. It's important for Russian-speaking users to check that the language and input settings load a quality voice packet, otherwise speech can sound robotic.
Control of the gaze and physical switches
Technology is moving, and you can now control your smartphone without your hands using only eye movement. The gaze control (available on devices with a front-facing camera with sufficient resolution and related software) monitors the position of the pupils and allows you to select elements on the screen just by looking at them.
For people with severe motor impairments, Switch Access is a technology that allows you to connect external physical buttons, joysticks or touch mats to your smartphone via USB-OTG or Bluetooth. By setting up a scan of interface elements, you can control the device by pressing just one or two buttons, a revolutionary opportunity for people with spinal injuries or cerebral palsy.
- 👀 Calibration: Before using eye control, you must undergo a calibration procedure under different lighting.
- 🔌 Compatibility: Switch Access supports most standard HID-Input devices without installing drivers.
- ⚙️ Flexibility: You can adjust the scan delay time and the order of bypassing interface elements.
How does the eye tracking algorithm work?
In Xiaomi devices, these features are often hidden in the depth of the menu or require activation through the app. ADB-It's a simple Bluetooth clicker that can be saved for someone who has lost the ability to control accurately.
Setting up the display, text and color scheme
For visually impaired users, content display settings are critical. Xiaomi’s special features feature features features tools to zoom in, resize fonts, and adjust color gamuts. The zoom feature allows you to create a temporary magnifying glass in any part of the screen, which is convenient for reading fine text on menus or websites without zoom fonts.
Large text increases the fonts throughout the system, but sometimes it is not enough. In such cases, the function of Fat text helps, which makes the characters clearer and contrasting. For people with color blindness tersedia, a color correction setting allows you to change the display modes (for example, deuteranomalia, protanomalia) to distinguish colors that normally merge.
Another useful feature is Color Inversion, which changes the black background to white and vice versa, which can be useful in bright sunlight or to reduce eye strain in the dark if the standard night mode is not enough.
💡
The combination of “Bold Text” + “High-contrast Text” significantly improves the readability of the interface for older people without the need to use a magnifying glass.
And the size of the interfaces, too, can be changed in the Screen Size section, and you can zoom in not just text, but also buttons, icons, and indentations, making the interface more airy and convenient for people with hand tremors who have difficulty getting through small buttons.
Auditory capabilities and visual notifications
For people with hearing impairments, Xiaomi smartphones offer a number of adaptive features. One of the key is Monophonic sound. Normally, stereo separates channels (left and right), which can lead to the loss of part of the audio stream if the user hears only in one ear.
Sound Amplification allows you to programmatically increase the volume of media and calls above standard limits, although it should be used with caution so as not to damage the speakers or hearing. A safer option is to adjust the equalizer and left/right channel balance to compensate for asymmetric hearing loss.
Visual notifications replace audio signals. A smartphone can flash when a call or message is incoming. MIUI also offers audio visualization when the phone vibrates or flashes the screen in the rhythm of music or ambient noise, helping hearing-impaired users “feel” the sound.
Settings → Sound and vibration → Additional sound settings → Visualization⚠️ Warning: Continuous use of flash for notifications can quickly drain the battery and cause the camera module to overheat.
Also worth mentioning is Live Transcribe, which translates spoken speech into text on the screen in real time, an indispensable tool for deaf people to communicate with others live, turning a smartphone into a pocket sign language interpreter.
