Fundamental Limitations of AR Symbology in Accidented Terrain
conference paper
While AR has successfully been deployed in the military air domain for decades, its use in the ground domain poses serious challenges. Some of these challenges result from technological limitations. However, others are more difficult or even impossible to resolve since they reflect fundamental human characteristics. The toughest-to-solve limitations are caused by our physiology, anatomy, and cognition. Eye physiology limitations are masking, contrast, and occlusion. The anatomical shape of the human head forces optics to be mounted in front of the inherently glare-protecting eye sockets. The problems of the brain with respect to AR are i) it’s not ‘build’ to perceive transparency, ii) its limited cognitive capacity, and iii) we intuitively use a world-referenced system. In this paper, we provide an in-depth analysis of these human factor limitations. Conclusion: AR does not come for free. Fundamental human limitations seriously constrain see-through AR systems for the infantry and should be considered in their design and deployment.
