One aspect of the invention provides a method for providing input to a computer. In some embodiments, the method includes the steps of emitting light from a registered light source, reflecting a first pattern of light emitted by the registered light source with at least two reflective elements, detecting the movement of at least one of the reflective elements, and translating the movement of the at least one reflective element to movement of a cursor on a viewing system such that there is a first relationship between the movement of the at least one reflective element and the movement of the cursor, detecting a change from the first pattern to a second pattern of light with the at least two reflective elements, and changing the relationship between the movement of the reflective element and the movement of the cursor from the first relationship to a second relationship.
