Monitor movement on a track controls Unity Camera

Hello, I am working, or about to be working, on a project where I would like to move a monitor along a railed track, and have the camera in Unity update its movement left or right to follow the track movement. I am attempting to do something like this

but on a smaller scale, and have, at certain points along the track, triggers that will spawn different animations.

I guess my question is, does anyone have any thoughts or ideas on how this is accomplished? My initial thought is using a gyroscope to get movement data and use that with some scripting to control the camera. On the unity side of things I will be fine, I am just wondering if there are other ways, or if people may have other ideas on how this is done, before I jump into spending money on trial and error modes. Thanks for any insight that anyone may be able to offer in advanced!

 

Just wanted to check back in a bump to see if any new ideas may pop up. Toying with the idea of trying a Laser Range Finder and reading in the distance data via USB.
