Have you ever seen one those video games that has headset/goggles you stand in and look around the virtual scene with? I'm building one of those, and I'm trying to design a simple controller. I need the output of the controller to emulate a mouse input. So if you look to the left, it's as if you were moving the mouse to the left. Supposing I use optical encoders, the pan and tilt will need to be in separate locations (a couple of inches apart). It seems that many mouse hacks online have the components very close together.
Do you think it's possible to have one of the encoders some distance away from the controller chip? For OEM purposes, is there a good mouse controller chip that will output USB protocol mouse movements that I could buy in bulk?
Many thanks for any suggestions. Cheers
