1. A vision-based gaming system comprising:

  • an optical device configured to receive light from a light source associated with a user game controller; and

    a computing device configured to;

    track movement of the user game controller within an image sensing area based on the light received from the light source,wherein the optical device has a variable field of vision such that the computing device is configured to track movement of the light source at multiple different distances from the optical device, wherein the variable field of vision is variable between a first field of vision and a second field of vision that has a larger area than the first field of vision; and

    adjust an acquisition rate of frames from the optical device, wherein the acquisition rate is proportional to a resolution of the images from the optical device.
