In recent years, Augmented Reality has become a very popular topic,both as a research and commercial field. This trend has originated with the useof mobile devices as computational core and display. The appearance of virtualobjects and their interaction with the real world is a key element in the success ofan Augmented Reality software. A common issue in this type of software is thevisual inconsistency between the virtual and real objects due to wrong illumination.Although illumination is a common research topic in Computer Graphics,few studies have been made about real time estimation of illumination direction.In this work we present a low-cost approach to detect the direction of the environmentillumination, allowing the illumination of virtual objects according tothe real light of the ambient, improving the integration of the scene. Our solutionis open-source, based on Arduino hardware and the presented system wasdeveloped on Android.
