Accessibility Request Support for Power Wheelchair Joystick and Bluetooth Mouse Inputs Meta Quest 3

Hello Meta Developer Community,

My name is Rodrigo Sologaistoa. I am a biologist pursuing a master’s degree in bioinformatics, and I work at the Biomolecule Simulation Laboratory at the Institut Pasteur de Montevideo.

I am also quadriplegic and a power wheelchair user. Because of my disability, I cannot use my hands to control the standard Meta Quest 3 controllers. However, in my daily computer setup, I use my Quantum power wheelchair joystick as an input device through Bluetooth, and I also use external right- and left-click buttons connected through a Bluetooth mouse setup.

I would like to ask whether there is currently any way to connect this type of accessibility input setup to the Meta Quest 3. Ideally, I would like to use my wheelchair joystick and Bluetooth mouse buttons to navigate and control the headset instead of using the standard handheld controllers.

Voice control is helpful for navigating parts of the Meta interface, but it is not enough for many apps. For example, I want to use Nanome, a molecular visualization and molecular dynamics application, for my research and academic work. Once inside the app, I need to move around, select, rotate, and interact with molecular structures, but I cannot do this with the standard Quest controllers.

This kind of support would be extremely valuable not only for my own research and academic independence, but also for other disabled users who rely on alternative input devices instead of handheld controllers.

I would appreciate any guidance from Meta developers or the community on the following questions:

1. Can Meta Quest 3 currently recognize a Bluetooth wheelchair joystick or Bluetooth mouse-style input device as a control method?
2. Are there any accessibility settings, experimental features, developer APIs, or workarounds that could support this?
3. Can app developers, such as Nanome or other scientific/educational VR apps, implement custom support for external Bluetooth input devices?
4. Is this type of alternative input support something Meta is considering for future versions of Horizon OS or Quest accessibility features?

Thank you very much for any advice, technical suggestions, or direction on where to submit this as a formal accessibility feature request.
