Abstract
Briefly, in accordance with one or more embodiments, an information handling system comprises a scanning system to scan one or more component wavelength beams into a combined multi-component beam in a first field of view, and a redirecting system to redirect one or more of the component wavelength beams into a second field of view. A first subset of the one or more component wavelength beams is projected in the first field of view and a second subset of the one or more component wavelength beams is projected in the second field of view. The first subset may project a visible image in the first field of view, and user is capable of providing an input to control the information handling system via interaction with the second subset in the second field of view.
