Just about everyone likes the simplicity of rotating an iOS display to switch between portrait/landscape modes, but the annoying thing about it is that it doesn't take into account viewing angle. So, playing certain games or viewing images from certain angles can result in eye/muscle strain and user fatigue. My idea is to create some external device that allows iOS devices to align with the user viewing angle, both for switching between portrait/landscape mode and adjusting the origin to {0,0,0} for game play from whatever the determined angle is. What do you think of this idea of relative positioning (although it would require extra hardware) as opposed to coping with the drawbacks of absolute positioning?
