Android and Apple products all have their own accessibility gestures, both intuitive and easy to remember...As long as you stay within the same operating system. As intuative as they are, moving from one system to another requires learning new gestures. Same goes for text to speech features like VoiceOver (Apple) or TalkBack (Google).
There also shouldn’t be patents associated to these kind of gestures and companies should not use these gestures as a way to keep the disabled within their own operating ecosystem.
