Track IR head tracking
iPhone apps like “SmoothTrack: Head Tracker” work with games that support FreeTrack or TrackIR protocol. With the new VR version, a head tracker would be very useful for mobile users who’s phones have head tracking built in! Imagine playing and leaning towards your phone to see the cockpit controls better, while peeking up at the runway with hands on the controls the whole time! That’s an experience I’d pay for.
