The iPhone is operated by touching the display with your finger. It's true that the touch display and iPhone are inseparable, but there are some people who can't touch the screen for some reason. In addition to physical disabilities, there may be cases where the display surface becomes shattered and cannot be touched when the iPhone is dropped.
In that case, you have the option of using a mouse or trackpad. iOS 13 has added mouse (or trackpad) support as one of the accessibility features. You can use a USB mouse if you use a conversion adapter, but since there is no cable, a Bluetooth mouse is easier to handle and is suitable for iPhone.
In order to use a Bluetooth mouse, pairing is required first. However, the location where pairing is performed with earphones and speakers is different, and the screen will be a collection of accessibility-related functions within the "Settings" app. As a function, it is part of "Assistive Touch" (an auxiliary function that replaces taps with something other than a finger), and pairing and button settings are performed on the management screen.
To work, open the screen in the order of "Settings" → "Accessibility" → "Touch" → "Assistive Touch", and turn on the "Assistive Touch" switch. Tap "Devices" in the middle of the same screen, tap "Bluetooth device ..." and then put your Bluetooth mouse in pairing mode and your mouse should be detected.
When pairing is complete, a round mouse pointer will appear on the iPhone display and move with the mouse. The functions assigned to the buttons can be changed, so why not customize them for ease of use?
