When I found an old Google Daydream phone vr headset at my thrift store, I grabbed it just because I thought it looked neat. Looking at the controller, though, I realized it'd be a nice little handheld clicker/mouse to have to interact with a pc at a distance.
I've never worked with BLE, or even much Rust, so I expect this to be extremely janky - but, it does work!
I've only tested this on my Debian computer with X11, YMMV on other systems.
Huge shoutout to Matteo P. and this article about hacking the Daydream controller, without his findings this probably wouldn't have been possible for me.
- Touchpad - Move mouse
- Touchpad Click - Left Click
- App Button - Right Click
- Home Button - Toggle Scroll Mode
- While in scroll mode, iPod style circular scrolling on the touchpad scrolls the mouse.
- Click home or the touchpad again to exit.
- Volume Up - Escape
- Volume Down - Meta/Command/Windows/Super Key
The IMU is currently ignored because I didn't want to have to figure out how to filter the motion data and get it working.
