I've built an app that has the same goals (not operate a mouse) but approach it completely different.<p>Rather than try to simulate the moving the mouse itself, Shortcat [<a href="https://shortcat.app/" rel="nofollow">https://shortcat.app/</a>] indexes the user interface (buttons, text fields, links, menus, etc) and enables fast fuzzy search of the interface. Type a word, abbreviations, or hints and hit Enter to click or action the element. Works almost everywhere on macOS, including browsers, Electron apps, and even iOS apps!<p>The goal is to minimise cognitive overhead to achieve a particular intent, so being able to type a word to hit a button, or active a deep menu item when you don't know the shortcut is quick and easy.<p>I'm currently working on a modal option which enables staying within Shortcat to navigate an interface, as well as chords for simulating scrolling and arrow keys.<p>Shortcat relies on using the Accessibility API to index UI elements however, and is dependent on how well an app or website has implemented it. One of the goals is to help improve accessibility implementations by exposing more people to its implementations and pushing for developers to fix broken or incorrectly implemented accessibility tagging.<p>Shortcat is macOS only for now as I haven't been able to investigate how viable doing this on Windows or Linux would be, especially on Linux considering all the different toolkits that exist.
