Assistive technology (AT) is a term for assistive, adaptive, and rehabilitative devices for people with disabilities or the elderly population. ADLs are self-care activities that include toileting, mobility (ambulation), eating, bathing, dressing, grooming, and personal device care. Assistive technology can ameliorate the effects of disabilities that limit the ability to perform ADLs.

Assistive Touch is a convenient tool for controlling various parameters on your Android smartphone using gestural shortcuts. So with just a small circular icon on your smartphone's screen, you can manage all kinds of processes in a really simple way.

From the Assistive Touch interface, you can adjust various parameters to modify processes on your smartphone. For example, you can set up shortcuts to access various adjustments when you slide your finger in a certain direction on the circle.

Use AssistiveTouch on your Android device.
You can use AssistiveTouch to adjust volume, lock your screen, use multi-finger gestures, restart your device, or replace pressing buttons with just a tap.

When you turn on AssistiveTouch, you'll see a button appear onscreen. You can drag it to any edge of the screen, where it will stay until you move it again. By default, tapping the button once will open the AssistiveTouch menu. Tapping once anywhere outside of the menu will close it.

AssistiveTouch can also be added to the Accessibility Shortcut for quick access from Control Center, or you can use the Side or Home button.

Use AssistiveTouch instead of gestures.

Access menus and controls that require onscreen gestures like:
- Control Center
- Notification Center
- Spotlight
- Home
- App Switcher
- Speak Screen

Use AssistiveTouch instead of pressing buttons.
The menu gives you access to functions that would otherwise be controlled by pressing physical buttons or moving the device. Here's some of what you can do:

- Activate the Accessibility Shortcut
- Lock the screen
- Adjust the volume
- Google Assistant
- Restart the device
- Capture a screenshot
- Simulate shaking the device

‘AssistiveTouch’ also allows you to perform tasks that would normally require you to press one of the device’s physical buttons such as going back to the ‘Home’ screen, activating ‘G Assistance’, adjusting the volume or opening the multitasking window.
