# Mouse
|
|
|
|
Several mouse input modes are available:
|
|
|
|
- `--mouse=sdk` (default)
|
|
- `--mouse=uhid` (or `-M`): simulates a physical HID mouse using the UHID
|
|
kernel module on the device
|
|
- `--mouse=aoa`: simulates a physical HID mouse using the AOAv2 protocol
|
|
- `--mouse=disabled`
|
|
|
|
|
|
## SDK mouse
|
|
|
|
In this mode (`--mouse=sdk`, or if the parameter is omitted), mouse input events
|
|
are injected at the Android API level with absolute coordinates.
|
|
|
|
Note that on some devices, an additional option must be enabled in developer
|
|
options for this mouse mode to work. See
|
|
[prerequisites](/README.md#prerequisites).
|
|
|
|
|
|
## Physical mouse simulation
|
|
|
|
Two modes allow to simulate a physical HID mouse on the device.
|
|
|
|
In these modes, the computer mouse is "captured": the mouse pointer disappears
|
|
from the computer and appears on the Android device instead.
|
|
|
|
Special capture keys, either <kbd>Alt</kbd> or <kbd>Super</kbd>, toggle
|
|
(disable or enable) the mouse capture. Use one of them to give the control of
|
|
the mouse back to the computer.
|
|
|
|
|
|
### UHID
|
|
|
|
This mode simulates a physical HID mouse using the [UHID] kernel module on the
|
|
device.
|
|
|
|
[UHID]: https://kernel.org/doc/Documentation/hid/uhid.txt
|
|
|
|
To enable UHID mouse, use:
|
|
|
|
```bash
|
|
scrcpy --mouse=uhid
|
|
scrcpy -M # short version
|
|
```
|
|
|
|
|
|
### AOA
|
|
|
|
This mode simulates a physical HID mouse using the [AOAv2] protocol.
|
|
|
|
[AOAv2]: https://source.android.com/devices/accessories/aoa2#hid-support
|
|
|
|
To enable AOA mouse, use:
|
|
|
|
```bash
|
|
scrcpy --mouse=aoa
|
|
```
|
|
|
|
Contrary to the other modes, it works at the USB level directly (so it only
|
|
works over USB).
|
|
|
|
It does not use the scrcpy server, and does not require `adb` (USB debugging).
|
|
Therefore, it is possible to control the device (but not mirror) even with USB
|
|
debugging disabled (see [OTG](otg.md)).
|
|
|
|
Note: On Windows, it may only work in [OTG mode](otg.md), not while mirroring
|
|
(it is not possible to open a USB device if it is already open by another
|
|
process like the _adb daemon_).
