Comparing mouse + Keyboard vs Touch Screen Input Devices?

Is there any research that compares the User Experience of using the mentioned Input Devices ? Thanks

Edit: Basically for my dissertation i'm planning on creating a usable interface for a voting machine. I'd like to use a touchscreen and I need some kind of academic research that I could use in my literature review to back-up my choice of input device. If you'd like me to specify more feel free to let me know.
