Logitech MX Ink for Meta Quest Platform

In collaboration with Meta, Logitech is introducing MX Ink, the first Mixed Reality (MR) stylus for the Meta Quest platform. MX Ink empowers users to engage in high-precision creativity and exercise precise control, allowing them to create, annotate, and navigate in MR environments. This GitHub repository explains the features of MX Ink from a developer perspective, and provides information to enable you to add support for the device in your app.

There is a new stylus-specific OpenXR Interaction Profile for MX Ink that should be used in your app to add support for a stylus. However to optimize legacy support and enable easier proototyping, the MX Ink also can report inputs via legacy Touch Controller fields.

• The user can dynamically swap controllers and stylus, i.e., seamless switch between stylus and controller usage at any time
• Meta Unity Core SDK V65 includes support for the stylus
• The developer can know that the device is in fact a stylus, as opposed to a standard Touch controller
• Stylus Setting Page in Quest OS that allows the user to customize the stylus, e.g., pressure curves, haptics, etc.
