It would be awesome to be able to interface with the Quest on a very basic level (moving a cursor and clicking buttons etc) without having a controller connected, for simple functions like watching movies.browsing the internet when in a car or on a plane etc. Perhaps we could use the volume/power buttons combined with the direction of our gaze to launch apps/go back/click a virtual cursor.

Obviously when hand tracking comes in, I hope this will allow such a feature, but it will likely still be impossible in low light, so a way to launch apps/watch videos on a dimly lit plane without a controller in my hand would be a real help, not to mention potentially opening up new options for users with physical impairments.
