Here's an article that discusses accessibility features in VisionOS: https://www.macrumors.com/2023/06/07/apple-vision-pro-access.... It's a summary of a WWDC session that I haven't watched. One of the items in the article says

> Dwell Control will provide on-screen options for Tap, Scroll, Long Press, and Drag, allowing for users to interact with the interface without using their hands.

Does the article address any of your concerns?
