Ask HN: How much could some one make if he makes a traditional mobile mouse app?

You mean something like this ? https://itunes.apple.com/us/app/remote-mouse-free-wireless-k...

I don'f quite understand what you want ot build. In general a moise only makes sense for screens bigget than a typical mouse-pad or phone screen or look arround stuff like 3D games

Accurately inferring the position of the mouse from its acceleration is a difficult problem (the integration involved will result in rather large errors that compound over time when calculating the velocity and position). I doubt that the return on a 'traditional mouse' app would reward the effort required to make this work.
