Remote control systems that can distinguish predetermined light sources from stray light sources, e.g., environmental light sources and/or reflections are provided. The predetermined light sources can be disposed in asymmetric substantially linear or two-dimensional patterns. The predetermined light sources also can be configured to exhibit signature characteristics. The predetermined light sources also can output light at different signature wavelengths. The predetermined light sources also can emit light polarized in one or more predetermined polarization axes. Remote control systems of the present invention also can include methods for adjusting an allocation of predetermined light sources and/or the technique used to distinguish the predetermined light sources from the stray light sources. |
