I have an augmented reality project I'm doing for a museum, using Unreal Engine. I've begun designing the controller (a pan and tilt visor you look through and move around). Originally, I was designing the input device to emulate a standard mouse output, but because it's augmented reality, will need really good absolute positioning. So I'm looking into absolute encoders for output- it needs to work as soon as you power on with no calibration required.
The question is two parts: if I start building my own input device which outputs discrete coordinates, rather than incremental x and y movement (as a traditional mouse controller chip does) 1) Can I get that data into Unreal Engine? 2) Can I control the camera rotation with that data?
The bigger question is- Is there a better way to do this? All I'm looking to do is build an Unreal Scene with a fixed virtual camera that is controlled by an external Pan/Tilt mechanism.
Many thanks for your input. Ha! Get it. Input.
